We discuss the latest trends in diffusion models, ask questions, show off personal projects, help each other with contributions, or just hang out ☕. <a href="https://Discord.gg/G7tWnz98XR"><img alt="Join us on Discord" src="https://img.shields.io/Discord/823813159592001537?color=5865F2&logo=Discord&logoColor=white"></a>
|
||||
It also helps us if you spread the word: reference the library from blog posts
|
||||
on the awesome projects it made possible, shout out on Twitter every time it has
|
||||
helped you, or simply star the repo to say "thank you".
|
||||
|
||||
Whichever way you choose to contribute, we strive to be part of an open, welcoming, and kind community. Please, read our [code of conduct](https://github.com/huggingface/diffusers/blob/main/CODE_OF_CONDUCT.md) and be mindful to respect it during your interactions. We also recommend you become familiar with the [ethical guidelines](https://huggingface.co/docs/diffusers/conceptual/ethical_guidelines) that guide our project and ask you to adhere to the same principles of transparency and responsibility.
|
||||
Whichever way you choose to contribute, please be mindful to respect our
|
||||
[code of conduct](https://github.com/huggingface/diffusers/blob/main/CODE_OF_CONDUCT.md).
|
||||
|
||||
We enormously value feedback from the community, so please do not be afraid to speak up if you believe you have valuable feedback that can help improve the library - every message, comment, issue, and pull request (PR) is read and considered.
|
||||
## You can contribute in so many ways!
|
||||
|
||||
## Overview
|
||||
There are 4 ways you can contribute to diffusers:
|
||||
* Fixing outstanding issues with the existing code;
|
||||
* Implementing [new diffusion pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines#contribution), [new schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers) or [new models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models)
|
||||
* [Contributing to the examples](https://github.com/huggingface/diffusers/tree/main/examples) or to the documentation;
|
||||
* Submitting issues related to bugs or desired new features.
|
||||
|
||||
You can contribute in many ways ranging from answering questions on issues to adding new diffusion models to
|
||||
the core library.
|
||||
In particular there is a special [Good First Issue](https://github.com/huggingface/diffusers/contribute) listing.
|
||||
It will give you a list of open Issues that are open to anybody to work on. Just comment in the issue that you'd like to work on it.
|
||||
In that same listing you will also find some Issues with `Good Second Issue` label. These are
|
||||
typically slightly more complicated than the Issues with just `Good First Issue` label. But if you
|
||||
feel you know what you're doing, go for it.
|
||||
|
||||
In the following, we give an overview of different ways to contribute, ranked by difficulty in ascending order. All of them are valuable to the community.
|
||||
*All are equally valuable to the community.*
|
||||
|
||||
* 1. Asking and answering questions on [the Diffusers discussion forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers) or on [Discord](https://discord.gg/G7tWnz98XR).
|
||||
* 2. Opening new issues on [the GitHub Issues tab](https://github.com/huggingface/diffusers/issues/new/choose)
|
||||
* 3. Answering issues on [the GitHub Issues tab](https://github.com/huggingface/diffusers/issues)
|
||||
* 4. Fix a simple issue, marked by the "Good first issue" label, see [here](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
|
||||
* 5. Contribute to the [documentation](https://github.com/huggingface/diffusers/tree/main/docs/source).
|
||||
* 6. Contribute a [Community Pipeline](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3Acommunity-examples)
|
||||
* 7. Contribute to the [examples](https://github.com/huggingface/diffusers/tree/main/examples).
|
||||
* 8. Fix a more difficult issue, marked by the "Good second issue" label, see [here](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+second+issue%22).
|
||||
* 9. Add a new pipeline, model, or scheduler, see ["New Pipeline/Model"](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22) and ["New scheduler"](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22) issues. For this contribution, please have a look at [Design Philosophy](https://github.com/huggingface/diffusers/blob/main/PHILOSOPHY.md).
|
||||
## Submitting a new issue or feature request
|
||||
|
||||
As said before, **all contributions are valuable to the community**.
|
||||
In the following, we will explain each contribution a bit more in detail.
|
||||
Do your best to follow these guidelines when submitting an issue or a feature
|
||||
request. It will make it easier for us to come back to you quickly and with good
|
||||
feedback.
|
||||
|
||||
For all contributions 4.-9. you will need to open a PR. It is explained in detail how to do so in [Opening a pull requst](#how-to-open-a-pr)
|
||||
|
||||
### 1. Asking and answering questions on the Diffusers discussion forum or on the Diffusers Discord
|
||||
|
||||
Any question or comment related to the Diffusers library can be asked on the [discussion forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/) or on [Discord](https://discord.gg/G7tWnz98XR). Such questions and comments include (but are not limited to):
|
||||
- Reports of training or inference experiments in an attempt to share knowledge
|
||||
- Presentation of personal projects
|
||||
- Questions to non-official training examples
|
||||
- Project proposals
|
||||
- General feedback
|
||||
- Paper summaries
|
||||
- Asking for help on personal projects that build on top of the Diffusers library
|
||||
- General questions
|
||||
- Ethical questions regarding diffusion models
|
||||
- ...
|
||||
|
||||
Every question that is asked on the forum or on Discord actively encourages the community to publicly
|
||||
share knowledge and might very well help a beginner in the future that has the same question you're
|
||||
having. Please do pose any questions you might have.
|
||||
In the same spirit, you are of immense help to the community by answering such questions because this way you are publicly documenting knowledge for everybody to learn from.
|
||||
|
||||
**Please** keep in mind that the more effort you put into asking or answering a question, the higher
|
||||
the quality of the publicly documented knowledge. In the same way, well-posed and well-answered questions create a high-quality knowledge database accessible to everybody, while badly posed questions or answers reduce the overall quality of the public knowledge database.
|
||||
In short, a high quality question or answer is *precise*, *concise*, *relevant*, *easy-to-understand*, *accesible*, and *well-formated/well-posed*. For more information, please have a look through the [How to write a good issue](#how-to-write-a-good-issue) section.
|
||||
|
||||
**NOTE about channels**:
|
||||
[*The forum*](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) is much better indexed by search engines, such as Google. Posts are ranked by popularity rather than chronologically. Hence, it's easier to look up questions and answers that we posted some time ago.
|
||||
In addition, questions and answers posted in the forum can easily be linked to.
|
||||
In contrast, *Discord* has a chat-like format that invites fast back-and-forth communication.
|
||||
While it will most likely take less time for you to get an answer to your question on Discord, your
|
||||
question won't be visible anymore over time. Also, it's much harder to find information that was posted a while back on Discord. We therefore strongly recommend using the forum for high-quality questions and answers in an attempt to create long-lasting knowledge for the community. If discussions on Discord lead to very interesting answers and conclusions, we recommend posting the results on the forum to make the information more available for future readers.
|
||||
|
||||
### 2. Opening new issues on the GitHub issues tab
|
||||
### Did you find a bug?
|
||||
|
||||
The 🧨 Diffusers library is robust and reliable thanks to the users who notify us of
|
||||
the problems they encounter. So thank you for reporting an issue.
|
||||
|
||||
Remember, GitHub issues are reserved for technical questions directly related to the Diffusers library, bug reports, feature requests, or feedback on the library design.
|
||||
First, we would really appreciate it if you could **make sure the bug was not
|
||||
already reported** (use the search bar on Github under Issues).
|
||||
|
||||
In a nutshell, this means that everything that is **not** related to the **code of the Diffusers library** (including the documentation) should **not** be asked on GitHub, but rather on either the [forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) or [Discord](https://discord.gg/G7tWnz98XR).
|
||||
### Do you want to implement a new diffusion pipeline / diffusion model?
|
||||
|
||||
**Please consider the following guidelines when opening a new issue**:
|
||||
- Make sure you have searched whether your issue has already been asked before (use the search bar on GitHub under Issues).
|
||||
- Please never report a new issue on another (related) issue. If another issue is highly related, please
|
||||
open a new issue nevertheless and link to the related issue.
|
||||
- Make sure your issue is written in English. Please use one of the great, free online translation services, such as [DeepL](https://www.deepl.com/translator) to translate from your native language to English if you are not comfortable in English.
|
||||
- Check whether your issue might be solved by updating to the newest Diffusers version. Before posting your issue, please make sure that `python -c "import diffusers; print(diffusers.__version__)"` is higher or matches the latest Diffusers version.
|
||||
- Remember that the more effort you put into opening a new issue, the higher the quality of your answer will be and the better the overall quality of the Diffusers issues.
|
||||
Awesome! Please provide the following information:
|
||||
|
||||
New issues usually include the following.
|
||||
* Short description of the diffusion pipeline and link to the paper;
|
||||
* Link to the implementation if it is open-source;
|
||||
* Link to the model weights if they are available.
|
||||
|
||||
#### 2.1. Reproducible, minimal bug reports.
|
||||
If you are willing to contribute the model yourself, let us know so we can best
|
||||
guide you.
|
||||
|
||||
A bug report should always have a reproducible code snippet and be as minimal and concise as possible.
|
||||
This means in more detail:
|
||||
- Narrow the bug down as much as you can, **do not just dump your whole code file**
|
||||
- Format your code
|
||||
- Do not include any external libraries except for Diffusers depending on them.
|
||||
- **Always** provide all necessary information about your environment; for this, you can run: `diffusers-cli env` in your shell and copy-paste the displayed information to the issue.
|
||||
- Explain the issue. If the reader doesn't know what the issue is and why it is an issue, she cannot solve it.
|
||||
- **Always** make sure the reader can reproduce your issue with as little effort as possible. If your code snippet cannot be run because of missing libraries or undefined variables, the reader cannot help you. Make sure your reproducible code snippet is as minimal as possible and can be copy-pasted into a simple Python shell.
|
||||
- If in order to reproduce your issue a model and/or dataset is required, make sure the reader has access to that model or dataset. You can always upload your model or dataset to the [Hub](https://huggingface.co) to make it easily downloadable. Try to keep your model and dataset as small as possible, to make the reproduction of your issue as effortless as possible.
|
||||
|
||||
For more information, please have a look through the [How to write a good issue](#how-to-write-a-good-issue) section.
|
||||
|
||||
You can open a bug report [here](https://github.com/huggingface/diffusers/issues/new/choose).
|
||||
|
||||
#### 2.2. Feature requests.
|
||||
### Do you want a new feature (that is not a model)?
|
||||
|
||||
A world-class feature request addresses the following points:
|
||||
|
||||
1. Motivation first:
|
||||
* Is it related to a problem/frustration with the library? If so, please explain
|
||||
why. Providing a code snippet that demonstrates the problem is best.
|
||||
* Is it related to something you would need for a project? We'd love to hear
|
||||
about it!
|
||||
* Is it something you worked on and think could benefit the community?
|
||||
Awesome! Tell us what problem it solved for you.
|
||||
* Is it related to a problem/frustration with the library? If so, please explain
|
||||
why. Providing a code snippet that demonstrates the problem is best.
|
||||
* Is it related to something you would need for a project? We'd love to hear
|
||||
about it!
|
||||
* Is it something you worked on and think could benefit the community?
|
||||
Awesome! Tell us what problem it solved for you.
|
||||
2. Write a *full paragraph* describing the feature;
|
||||
3. Provide a **code snippet** that demonstrates its future use;
|
||||
4. In case this is related to a paper, please attach a link;
|
||||
5. Attach any additional information (drawings, screenshots, etc.) you think may help.
|
||||
|
||||
You can open a feature request [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feature_request.md&title=).
|
||||
If your issue is well written we're already 80% of the way there by the time you
|
||||
post it.
|
||||
|
||||
#### 2.3 Feedback.
|
||||
|
||||
Feedback about the library design and why it is good or not good helps the core maintainers immensely to build a user-friendly library. To understand the philosophy behind the current design philosophy, please have a look [here](https://huggingface.co/docs/diffusers/conceptual/philosophy). If you feel like a certain design choice does not fit with the current design philosophy, please explain why and how it should be changed. If a certain design choice follows the design philosophy too much, hence restricting use cases, explain why and how it should be changed.
|
||||
If a certain design choice is very useful for you, please also leave a note as this is great feedback for future design decisions.
|
||||
|
||||
You can open an issue about feedback [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=).
|
||||
|
||||
#### 2.4 Technical questions.
|
||||
|
||||
Technical questions are mainly about why certain code of the library was written in a certain way, or what a certain part of the code does. Please make sure to link to the code in question and please provide detail on
|
||||
why this part of the code is difficult to understand.
|
||||
|
||||
You can open an issue about a technical question [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=bug&template=bug-report.yml).
|
||||
|
||||
#### 2.5 Proposal to add a new model, scheduler, or pipeline.
|
||||
|
||||
If the diffusion model community released a new model, pipeline, or scheduler that you would like to see in the Diffusers library, please provide the following information:
|
||||
|
||||
* Short description of the diffusion pipeline, model, or scheduler and link to the paper or public release.
|
||||
* Link to any of its open-source implementation.
|
||||
* Link to the model weights if they are available.
|
||||
|
||||
If you are willing to contribute to the model yourself, let us know so we can best guide you. Also, don't forget
|
||||
to tag the original author of the component (model, scheduler, pipeline, etc.) by GitHub handle if you can find it.
|
||||
|
||||
You can open a request for a model/pipeline/scheduler [here](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=New+model%2Fpipeline%2Fscheduler&template=new-model-addition.yml).
|
||||
|
||||
### 3. Answering issues on the GitHub issues tab
|
||||
|
||||
Answering issues on GitHub might require some technical knowledge of Diffusers, but we encourage everybody to give it a try even if you are not 100% certain that your answer is correct.
|
||||
Some tips to give a high-quality answer to an issue:
|
||||
- Be as concise and minimal as possible
|
||||
- Stay on topic. An answer to the issue should concern the issue and only the issue.
|
||||
- Provide links to code, papers, or other sources that prove or encourage your point.
|
||||
- Answer in code. If a simple code snippet is the answer to the issue or shows how the issue can be solved, please provide a fully reproducible code snippet.
|
||||
|
||||
Also, many issues tend to be simply off-topic, duplicates of other issues, or irrelevant. It is of great
|
||||
help to the maintainers if you can answer such issues, encouraging the author of the issue to be
|
||||
more precise, provide the link to a duplicated issue or redirect them to [the forum](https://discuss.huggingface.co/c/discussion-related-to-httpsgithubcomhuggingfacediffusers/63) or [Discord](https://discord.gg/G7tWnz98XR)
|
||||
|
||||
If you have verified that the issued bug report is correct and requires a correction in the source code,
|
||||
please have a look at the next sections.
|
||||
|
||||
For all of the following contributions, you will need to open a PR. It is explained in detail how to do so in the [Opening a pull requst](#how-to-open-a-pr) section.
|
||||
|
||||
### 4. Fixing a "Good first issue"
|
||||
|
||||
*Good first issues* are marked by the [Good first issue](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22) label. Usually, the issue already
|
||||
explains how a potential solution should look so that it is easier to fix.
|
||||
If the issue hasn't been closed and you would like to try to fix this issue, you can just leave a message "I would like to try this issue.". There are usually three scenarios:
|
||||
- a.) The issue description already proposes a fix. In this case and if the solution makes sense to you, you can open a PR or draft PR to fix it.
|
||||
- b.) The issue description does not propose a fix. In this case, you can ask what a proposed fix could look like and someone from the Diffusers team should answer shortly. If you have a good idea of how to fix it, feel free to directly open a PR.
|
||||
- c.) There is already an open PR to fix the issue, but the issue hasn't been closed yet. If the PR has gone stale, you can simply open a new PR and link to the stale PR. PRs often go stale if the original contributor who wanted to fix the issue suddenly cannot find the time anymore to proceed. This often happens in open-source and is very normal. In this case, the community will be very happy if you give it a new try and leverage the knowledge of the existing PR. If there is already a PR and it is active, you can help the author by giving suggestions, reviewing the PR or even asking whether you can contribute to the PR.
|
||||
|
||||
|
||||
### 5. Contribute to the documentation
|
||||
|
||||
A good library **always** has good documentation! The official documentation is often one of the first points of contact for new users of the library, and therefore contributing to the documentation is a **highly
|
||||
valuable contribution**.
|
||||
|
||||
Contributing to the library can have many forms:
|
||||
|
||||
- Correcting spelling or grammatical errors.
|
||||
- Correct incorrect formatting of the docstring. If you see that the official documentation is weirdly displayed or a link is broken, we are very happy if you take some time to correct it.
|
||||
- Correct the shape or dimensions of a docstring input or output tensor.
|
||||
- Clarify documentation that is hard to understand or incorrect.
|
||||
- Update outdated code examples.
|
||||
- Translating the documentation to another language.
|
||||
|
||||
Anything displayed on [the official Diffusers doc page](https://huggingface.co/docs/diffusers/index) is part of the official documentation and can be corrected, adjusted in the respective [documentation source](https://github.com/huggingface/diffusers/tree/main/docs/source).
|
||||
|
||||
Please have a look at [this page](https://github.com/huggingface/diffusers/tree/main/docs) on how to verify changes made to the documentation locally.
|
||||
|
||||
|
||||
### 6. Contribute a community pipeline
|
||||
|
||||
[Pipelines](https://huggingface.co/docs/diffusers/api/pipelines/overview) are usually the first point of contact between the Diffusers library and the user.
|
||||
Pipelines are examples of how to use Diffusers [models](https://huggingface.co/docs/diffusers/api/models) and [schedulers](https://huggingface.co/docs/diffusers/api/schedulers/overview).
|
||||
We support two types of pipelines:
|
||||
|
||||
- Official Pipelines
|
||||
- Community Pipelines
|
||||
|
||||
Both official and community pipelines follow the same design and consist of the same type of components.
|
||||
|
||||
Official pipelines are tested and maintained by the core maintainers of Diffusers. Their code
|
||||
resides in [src/diffusers/pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines).
|
||||
In contrast, community pipelines are contributed and maintained purely by the **community** and are **not** tested.
|
||||
They reside in [examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) and while they can be accessed via the [PyPI diffusers package](https://pypi.org/project/diffusers/), their code is not part of the PyPI distribution.
|
||||
|
||||
The reason for the distinction is that the core maintainers of the Diffusers library cannot maintain and test all
|
||||
possible ways diffusion models can be used for inference, but some of them may be of interest to the community.
|
||||
Officially released diffusion pipelines,
|
||||
such as Stable Diffusion are added to the core src/diffusers/pipelines package which ensures
|
||||
high quality of maintenance, no backward-breaking code changes, and testing.
|
||||
More bleeding edge pipelines should be added as community pipelines. If usage for a community pipeline is high, the pipeline can be moved to the official pipelines upon request from the community. This is one of the ways we strive to be a community-driven library.
|
||||
|
||||
To add a community pipeline, one should add a <name-of-the-community>.py file to [examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) and adapt the [examples/community/README.md](https://github.com/huggingface/diffusers/tree/main/examples/community/README.md) to include an example of the new pipeline.
|
||||
|
||||
An example can be seen [here](https://github.com/huggingface/diffusers/pull/2400).
|
||||
|
||||
Community pipeline PRs are only checked at a superficial level and ideally they should be maintained by their original authors.
|
||||
|
||||
Contributing a community pipeline is a great way to understand how Diffusers models and schedulers work. Having contributed a community pipeline is usually the first stepping stone to contributing an official pipeline to the
|
||||
core package.
|
||||
|
||||
### 7. Contribute to training examples
|
||||
|
||||
Diffusers examples are a collection of training scripts that reside in [examples](https://github.com/huggingface/diffusers/tree/main/examples).
|
||||
|
||||
We support two types of training examples:
|
||||
|
||||
- Official training examples
|
||||
- Research training examples
|
||||
|
||||
Research training examples are located in [examples/research_projects](https://github.com/huggingface/diffusers/tree/main/examples/research_projects) whereas official training examples include all folders under [examples](https://github.com/huggingface/diffusers/tree/main/examples) except the `research_projects` and `community` folders.
|
||||
The official training examples are maintained by the Diffusers' core maintainers whereas the research training examples are maintained by the community.
|
||||
This is because of the same reasons put forward in [6. Contribute a community pipeline](#contribute-a-community-pipeline) for official pipelines vs. community pipelines: It is not feasible for the core maintainers to maintain all possible training methods for diffusion models.
|
||||
If the Diffusers core maintainers and the community consider a certain training paradigm to be too experimental or not popular enough, the corresponding training code should be put in the `research_projects` folder and maintained by the author.
|
||||
|
||||
Both official training and research examples consist of a directory that contains one or more training scripts, a requirements.txt file, and a README.md file. In order for the user to make use of the
|
||||
training examples, it is required to clone the repository:
|
||||
|
||||
```
|
||||
git clone https://github.com/huggingface/diffusers
|
||||
```
|
||||
|
||||
as well as to install all additional dependencies required for training:
|
||||
|
||||
```
|
||||
pip install -r /examples/<your-example-folder>/requirements.txt
|
||||
```
|
||||
|
||||
Therefore when adding an example, the `requirements.txt` file shall define all pip dependencies required for your training example so that once all those are installed, the user can run the example's training script. See, for example, the [DreamBooth `requirements.txt` file](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/requirements.txt).
|
||||
|
||||
Training examples of the Diffusers library should adhere to the following philosophy:
|
||||
- All the code necessary to run the examples should be found in a single Python file
|
||||
- One should be able to run the example from the command line with `python <your-example>.py --args`
|
||||
- Examples should be kept simple and serve as **an example** on how to use Diffusers for training. The purpose of example scripts is **not** to create state-of-the-art diffusion models, but rather to reproduce known training schemes without adding too much custom logic. As a byproduct of this point, our examples also strive to serve as good educational materials.
|
||||
|
||||
To contribute an example, it is highly recommended to look at already existing examples such as [dreambooth](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth.py) to get an idea of how they should look like.
|
||||
We strongly advise contributors to make use of the [Accelerate library](https://github.com/huggingface/accelerate) as it's tightly integrated
|
||||
with Diffusers.
|
||||
Once an example script works, please make sure to add a comprehensive `README.md` that states how to use the example exactly. This README should include:
|
||||
- An example command on how to run the example script as shown [here e.g.](https://github.com/huggingface/diffusers/tree/main/examples/dreambooth#running-locally-with-pytorch).
|
||||
- A link to some training results (logs, models, ...) that show what the user can expect as shown [here e.g.](https://api.wandb.ai/report/patrickvonplaten/xm6cd5q5).
|
||||
- If you are adding a non-official/research training example, **please don't forget** to add a sentence that you are maintaining this training example which includes your git handle as shown [here](https://github.com/huggingface/diffusers/tree/main/examples/research_projects/intel_opts#diffusers-examples-with-intel-optimizations).
|
||||
|
||||
If you are contributing to the official training examples, please also make sure to add a test to [examples/test_examples.py](https://github.com/huggingface/diffusers/blob/main/examples/test_examples.py). This is not necessary for non-official training examples.

### 8. Fixing a "Good second issue"
|
||||
|
||||
*Good second issues* are marked by the [Good second issue](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+second+issue%22) label. Good second issues are
|
||||
usually more complicated to solve than [Good first issues](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
|
||||
The issue description usually gives less guidance on how to fix the issue and requires
|
||||
a decent understanding of the library by the interested contributor.
|
||||
If you are interested in tackling a second good issue, feel free to open a PR to fix it and link the PR to the issue. If you see that a PR has already been opened for this issue but did not get merged, have a look to understand why it wasn't merged and try to open an improved PR.
|
||||
Good second issues are usually more difficult to get merged compared to good first issues, so don't hesitate to ask for help from the core maintainers. If your PR is almost finished the core maintainers can also jump into your PR and commit to it in order to get it merged.
|
||||
|
||||
### 9. Adding pipelines, models, schedulers
|
||||
|
||||
Pipelines, models, and schedulers are the most important pieces of the Diffusers library.
|
||||
They provide easy access to state-of-the-art diffusion technologies and thus allow the community to
|
||||
build powerful generative AI applications.
|
||||
|
||||
By adding a new model, pipeline, or scheduler you might enable a new powerful use case for any of the user interfaces relying on Diffusers which can be of immense value for the whole generative AI ecosystem.
|
||||
|
||||
Diffusers has a couple of open feature requests for all three components - feel free to gloss over them
|
||||
if you don't know yet what specific component you would like to add:
|
||||
- [Model or pipeline](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22)
|
||||
- [Scheduler](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22)
|
||||
|
||||
Before adding any of the three components, it is strongly recommended that you give the [Philosophy guide](https://github.com/huggingface/diffusers/blob/main/PHILOSOPHY.md) a read to better understand the design of any of the three components. Please be aware that
|
||||
we cannot merge model, scheduler, or pipeline additions that strongly diverge from our design philosophy
|
||||
as it will lead to API inconsistencies. If you fundamentally disagree with a design choice, please
|
||||
open a [Feedback issue](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=) instead so that it can be discussed whether a certain design
|
||||
pattern/design choice shall be changed everywhere in the library and whether we shall update our design philosophy. Consistency across the library is very important for us.
|
||||
|
||||
Please make sure to add links to the original codebase/paper to the PR and ideally also ping the
|
||||
original author directly on the PR so that they can follow the progress and potentially help with questions.
|
||||
|
||||
If you are unsure or stuck in the PR, don't hesitate to leave a message to ask for a first review or help.

||||
|
||||
## How to write a good issue
|
||||
|
||||
**The better your issue is written, the higher the chances that it will be quickly resolved.**
|
||||
|
||||
1. Make sure that you've used the correct template for your issue. You can pick between *Bug Report*, *Feature Request*, *Feedback about API Design*, *New model/pipeline/scheduler addition*, *Forum*, or a blank issue. Make sure to pick the correct one when opening [a new issue](https://github.com/huggingface/diffusers/issues/new/choose).
|
||||
2. **Be precise**: Give your issue a fitting title. Try to formulate your issue description as simple as possible. The more precise you are when submitting an issue, the less time it takes to understand the issue and potentially solve it. Make sure to open an issue for one issue only and not for multiple issues. If you found multiple issues, simply open multiple issues. If your issue is a bug, try to be as precise as possible about what bug it is - you should not just write "Error in diffusers".
|
||||
3. **Reproducibility**: No reproducible code snippet == no solution. If you encounter a bug, maintainers **have to be able to reproduce** it. Make sure that you include a code snippet that can be copy-pasted into a Python interpreter to reproduce the issue. Make sure that your code snippet works, *i.e.* that there are no missing imports or missing links to images, ... Your issue should contain an error message **and** a code snippet that can be copy-pasted without any changes to reproduce the exact same error message. If your issue is using local model weights or local data that cannot be accessed by the reader, the issue cannot be solved. If you cannot share your data or model, try to make a dummy model or dummy data.
|
||||
4. **Minimalistic**: Try to help the reader as much as you can to understand the issue as quickly as possible by staying as concise as possible. Remove all code / all information that is irrelevant to the issue. If you have found a bug, try to create the easiest code example you can to demonstrate your issue, do not just dump your whole workflow into the issue as soon as you have found a bug. E.g., if you train a model and get an error at some point during the training, you should first try to understand what part of the training code is responsible for the error and try to reproduce it with a couple of lines. Try to use dummy data instead of full datasets.
|
||||
5. Add links. If you are referring to a certain naming, method, or model make sure to provide a link so that the reader can better understand what you mean. If you are referring to a specific PR or issue, make sure to link it to your issue. Do not assume that the reader knows what you are talking about. The more links you add to your issue the better.
|
||||
6. Formatting. Make sure to nicely format your issue by formatting code into Python code syntax, and error messages into normal code syntax. See the [official GitHub formatting docs](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax) for more information.
|
||||
7. Think of your issue not as a ticket to be solved, but rather as a beautiful entry to a well-written encyclopedia. Every added issue is a contribution to publicly available knowledge. By adding a nicely written issue you not only make it easier for maintainers to solve your issue, but you are helping the whole community to better understand a certain aspect of the library.
|
||||
|
||||
## How to write a good PR
|
||||
|
||||
1. Be a chameleon. Understand existing design patterns and syntax and make sure your code additions flow seamlessly into the existing code base. Pull requests that significantly diverge from existing design patterns or user interfaces will not be merged.
|
||||
2. Be laser focused. A pull request should solve one problem and one problem only. Make sure to not fall into the trap of "also fixing another problem while we're adding it". It is much more difficult to review pull requests that solve multiple, unrelated problems at once.
|
||||
3. If helpful, try to add a code snippet that displays an example of how your addition can be used.
|
||||
4. The title of your pull request should be a summary of its contribution.
|
||||
5. If your pull request addresses an issue, please mention the issue number in
|
||||
the pull request description to make sure they are linked (and people
|
||||
consulting the issue know you are working on it);
|
||||
6. To indicate a work in progress please prefix the title with `[WIP]`. These
|
||||
are useful to avoid duplicated work, and to differentiate it from PRs ready
|
||||
to be merged;
|
||||
7. Try to formulate and format your text as explained in [How to write a good issue](#how-to-write-a-good-issue).
|
||||
8. Make sure existing tests pass;
|
||||
9. Add high-coverage tests. No quality testing = no merge.
|
||||
- If you are adding new `@slow` tests, make sure they pass using
|
||||
`RUN_SLOW=1 python -m pytest tests/test_my_new_model.py`.
|
||||
CircleCI does not run the slow tests, but GitHub actions does every night!
|
||||
10. All public methods must have informative docstrings that work nicely with markdown. See `[pipeline_latent_diffusion.py](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/latent_diffusion/pipeline_latent_diffusion.py)` for an example.
|
||||
11. Due to the rapidly growing repository, it is important to make sure that no files that would significantly weigh down the repository are added. This includes images, videos, and other non-text files. We prefer to leverage a hf.co hosted `dataset` like
|
||||
[`hf-internal-testing`](https://huggingface.co/hf-internal-testing) or [huggingface/documentation-images](https://huggingface.co/datasets/huggingface/documentation-images) to place these files.
|
||||
If an external contribution, feel free to add the images to your PR and ask a Hugging Face member to migrate your images
|
||||
to this dataset.

||||
|
||||
```bash
|
||||
$ git clone git@github.com:<your Github handle>/diffusers.git
|

# Philosophy
|
||||
|
||||
🧨 Diffusers provides **state-of-the-art** pretrained diffusion models across multiple modalities.
|
||||
Its purpose is to serve as a **modular toolbox** for both inference and training.
|
||||
|
||||
We aim at building a library that stands the test of time and therefore take API design very seriously.
|
||||
|
||||
In a nutshell, Diffusers is built to be a natural extension of PyTorch. Therefore, most of our design choices are based on [PyTorch's Design Principles](https://pytorch.org/docs/stable/community/design.html#pytorch-design-philosophy). Let's go over the most important ones:
|
||||
|
||||
## Usability over Performance
|
||||
|
||||
- While Diffusers has many built-in performance-enhancing features (see [Memory and Speed](https://huggingface.co/docs/diffusers/optimization/fp16)), models are always loaded with the highest precision and lowest optimization. Therefore, by default diffusion pipelines are always instantiated on CPU with float32 precision if not otherwise defined by the user. This ensures usability across different platforms and accelerators and means that no complex installations are required to run the library.
|
||||
- Diffusers aim at being a **light-weight** package and therefore has very few required dependencies, but many soft dependencies that can improve performance (such as `accelerate`, `safetensors`, `onnx`, etc...). We strive to keep the library as lightweight as possible so that it can be added without much concern as a dependency on other packages.
|
||||
- Diffusers prefers simple, self-explainable code over condensed, magic code. This means that short-hand code syntaxes such as lambda functions, and advanced PyTorch operators are often not desired.
|
||||
|
||||
## Simple over easy
|
||||
|
||||
As PyTorch states, **explicit is better than implicit** and **simple is better than complex**. This design philosophy is reflected in multiple parts of the library:
|
||||
- We follow PyTorch's API with methods like [`DiffusionPipeline.to`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.to) to let the user handle device management.
|
||||
- Raising concise error messages is preferred to silently correct erroneous input. Diffusers aims at teaching the user, rather than making the library as easy to use as possible.
|
||||
- Complex model vs. scheduler logic is exposed instead of magically handled inside. Schedulers/Samplers are separated from diffusion models with minimal dependencies on each other. This forces the user to write the unrolled denoising loop. However, the separation allows for easier debugging and gives the user more control over adapting the denoising process or switching out diffusion models or schedulers.
|
||||
- Separately trained components of the diffusion pipeline, *e.g.* the text encoder, the unet, and the variational autoencoder, each have their own model class. This forces the user to handle the interaction between the different model components, and the serialization format separates the model components into different files. However, this allows for easier debugging and customization. Dreambooth or textual inversion training
|
||||
is very simple thanks to diffusers' ability to separate single components of the diffusion pipeline.
|
||||
|
||||
## Tweakable, contributor-friendly over abstraction
|
||||
|
||||
For large parts of the library, Diffusers adopts an important design principle of the [Transformers library](https://github.com/huggingface/transformers), which is to prefer copy-pasted code over hasty abstractions. This design principle is very opinionated and stands in stark contrast to popular design principles such as [Don't repeat yourself (DRY)](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself).
|
||||
In short, just like Transformers does for modeling files, diffusers prefers to keep an extremely low level of abstraction and very self-contained code for pipelines and schedulers.
|
||||
Functions, long code blocks, and even classes can be copied across multiple files which at first can look like a bad, sloppy design choice that makes the library unmaintainable.
|
||||
**However**, this design has proven to be extremely successful for Transformers and makes a lot of sense for community-driven, open-source machine learning libraries because:
|
||||
- Machine Learning is an extremely fast-moving field in which paradigms, model architectures, and algorithms are changing rapidly, which therefore makes it very difficult to define long-lasting code abstractions.
|
||||
- Machine Learning practitioners like to be able to quickly tweak existing code for ideation and research and therefore prefer self-contained code over one that contains many abstractions.
|
||||
- Open-source libraries rely on community contributions and therefore must build a library that is easy to contribute to. The more abstract the code, the more dependencies, the harder to read, and the harder to contribute to. Contributors simply stop contributing to very abstract libraries out of fear of breaking vital functionality. If contributing to a library cannot break other fundamental code, not only is it more inviting for potential new contributors, but it is also easier to review and contribute to multiple parts in parallel.
|
||||
|
||||
At Hugging Face, we call this design the **single-file policy** which means that almost all of the code of a certain class should be written in a single, self-contained file. To read more about the philosophy, you can have a look
|
||||
at [this blog post](https://huggingface.co/blog/transformers-design-philosophy).
|
||||
|
||||
In diffusers, we follow this philosophy for both pipelines and schedulers, but only partly for diffusion models. The reason we don't follow this design fully for diffusion models is because almost all diffusion pipelines, such
|
||||
as [DDPM](https://huggingface.co/docs/diffusers/v0.12.0/en/api/pipelines/ddpm), [Stable Diffusion](https://huggingface.co/docs/diffusers/v0.12.0/en/api/pipelines/stable_diffusion/overview#stable-diffusion-pipelines), [UnCLIP (Dalle-2)](https://huggingface.co/docs/diffusers/v0.12.0/en/api/pipelines/unclip#overview) and [Imagen](https://imagen.research.google/) all rely on the same diffusion model, the [UNet](https://huggingface.co/docs/diffusers/api/models#diffusers.UNet2DConditionModel).
|
||||
|
||||
Great, now you should have generally understood why 🧨 Diffusers is designed the way it is 🤗.
|
||||
We try to apply these design principles consistently across the library. Nevertheless, there are some minor exceptions to the philosophy or some unlucky design choices. If you have feedback regarding the design, we would ❤️ to hear it [directly on GitHub](https://github.com/huggingface/diffusers/issues/new?assignees=&labels=&template=feedback.md&title=).
|
||||
|
||||
## Design Philosophy in Details
|
||||
|
||||
Now, let's look a bit into the nitty-gritty details of the design philosophy. Diffusers essentially consist of three major classes, [pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines), [models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models), and [schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers).
|
||||
Let's walk through more in-detail design decisions for each class.
|
||||
|
||||
### Pipelines
|
||||
|
||||
Pipelines are designed to be easy to use (therefore do not follow [*Simple over easy*](#simple-over-easy) 100%)), are not feature complete, and should loosely be seen as examples of how to use [models](#models) and [schedulers](#schedulers) for inference.
|
||||
|
||||
The following design principles are followed:
|
||||
- Pipelines follow the single-file policy. All pipelines can be found in individual directories under src/diffusers/pipelines. One pipeline folder corresponds to one diffusion paper/project/release. Multiple pipeline files can be gathered in one pipeline folder, as it’s done for [`src/diffusers/pipelines/stable-diffusion`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/stable_diffusion). If pipelines share similar functionality, one can make use of the [#Copied from mechanism](https://github.com/huggingface/diffusers/blob/125d783076e5bd9785beb05367a2d2566843a271/src/diffusers/pipelines/stable_diffusion/pipeline_stable_diffusion_img2img.py#L251).
|
||||
- Pipelines all inherit from [`DiffusionPipeline`]
|
||||
- Every pipeline consists of different model and scheduler components, that are documented in the [`model_index.json` file](https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/model_index.json), are accessible under the same name as attributes of the pipeline and can be shared between pipelines with [`DiffusionPipeline.components`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.components) function.
|
||||
- Every pipeline should be loadable via the [`DiffusionPipeline.from_pretrained`](https://huggingface.co/docs/diffusers/main/en/api/diffusion_pipeline#diffusers.DiffusionPipeline.from_pretrained) function.
|
||||
- Pipelines should be used **only** for inference.
|
||||
- Pipelines should be very readable, self-explanatory, and easy to tweak.
|
||||
- Pipelines should be designed to build on top of each other and be easy to integrate into higher-level APIs.
|
||||
- Pipelines are **not** intended to be feature-complete user interfaces. For future complete user interfaces one should rather have a look at [InvokeAI](https://github.com/invoke-ai/InvokeAI), [Diffuzers](https://github.com/abhishekkrthakur/diffuzers), and [lama-cleaner](https://github.com/Sanster/lama-cleaner)
|
||||
- Every pipeline should have one and only one way to run it via a `__call__` method. The naming of the `__call__` arguments should be shared across all pipelines.
|
||||
- Pipelines should be named after the task they are intended to solve.
|
||||
- In almost all cases, novel diffusion pipelines shall be implemented in a new pipeline folder/file.
|
||||
|
||||
### Models
|
||||
|
||||
Models are designed as configurable toolboxes that are natural extensions of [PyTorch's Module class](https://pytorch.org/docs/stable/generated/torch.nn.Module.html). They only partly follow the **single-file policy**.
|
||||
|
||||
The following design principles are followed:
|
||||
- Models correspond to **a type of model architecture**. *E.g.* the [`UNet2DConditionModel`] class is used for all UNet variations that expect 2D image inputs and are conditioned on some context.
|
||||
- All models can be found in [`src/diffusers/models`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models) and every model architecture shall be defined in its file, e.g. [`unet_2d_condition.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unet_2d_condition.py), [`transformer_2d.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/transformer_2d.py), etc...
|
||||
- Models **do not** follow the single-file policy and should make use of smaller model building blocks, such as [`attention.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention.py), [`resnet.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/resnet.py), [`embeddings.py`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/embeddings.py), etc... **Note**: This is in stark contrast to Transformers' modeling files and shows that models do not really follow the single-file policy.
|
||||
- Models intend to expose complexity, just like PyTorch's module does, and give clear error messages.
|
||||
- Models all inherit from `ModelMixin` and `ConfigMixin`.
|
||||
- Models can be optimized for performance when it doesn’t demand major code changes, keeps backward compatibility, and gives significant memory or compute gain.
|
||||
- Models should by default have the highest precision and lowest performance setting.
|
||||
- To integrate new model checkpoints whose general architecture can be classified as an architecture that already exists in Diffusers, the existing model architecture shall be adapted to make it work with the new checkpoint. One should only create a new file if the model architecture is fundamentally different.
|
||||
- Models should be designed to be easily extendable to future changes. This can be achieved by limiting public function arguments, configuration arguments, and "foreseeing" future changes, *e.g.* it is usually better to add `string` "...type" arguments that can easily be extended to new future types instead of boolean `is_..._type` arguments. Only the minimum amount of changes shall be made to existing architectures to make a new model checkpoint work.
|
||||
- The model design is a difficult trade-off between keeping code readable and concise and supporting many model checkpoints. For most parts of the modeling code, classes shall be adapted for new model checkpoints, while there are some exceptions where it is preferred to add new classes to make sure the code is kept concise and
|
||||
readable longterm, such as [UNet blocks](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/unet_2d_blocks.py) and [Attention processors](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
|
||||
|
||||
### Schedulers
|
||||
|
||||
Schedulers are responsible to guide the denoising process for inference as well as to define a noise schedule for training. They are designed as individual classes with loadable configuration files and strongly follow the **single-file policy**.
|
||||
|
||||
The following design principles are followed:
|
||||
- All schedulers are found in [`src/diffusers/schedulers`](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers).
|
||||
- Schedulers are **not** allowed to import from large utils files and shall be kept very self-contained.
|
||||
- One scheduler python file corresponds to one scheduler algorithm (as might be defined in a paper).
|
||||
- If schedulers share similar functionalities, we can make use of the `#Copied from` mechanism.
|
||||
- Schedulers all inherit from `SchedulerMixin` and `ConfigMixin`.
|
||||
- Schedulers can be easily swapped out with the [`ConfigMixin.from_config`](https://huggingface.co/docs/diffusers/main/en/api/configuration#diffusers.ConfigMixin.from_config) method as explained in detail [here](./using-diffusers/schedulers.md).
|
||||
- Every scheduler has to have a `set_num_inference_steps`, and a `step` function. `set_num_inference_steps(...)` has to be called before every denoising process, *i.e.* before `step(...)` is called.
|
||||
- Every scheduler exposes the timesteps to be "looped over" via a `timesteps` attribute, which is an array of timesteps the model will be called upon
|
||||
- The `step(...)` function takes a predicted model output and the "current" sample (x_t) and returns the "previous", slightly more denoised sample (x_t-1).
|
||||
- Given the complexity of diffusion schedulers, the `step` function does not expose all the complexity and can be a bit of a "black box".
|
||||
- In almost all cases, novel schedulers shall be implemented in a new scheduling file.

🤗 Diffusers is the go-to library for state-of-the-art pretrained diffusion models for generating images, audio, and even 3D structures of molecules. Whether you're looking for a simple inference solution or training your own diffusion models, 🤗 Diffusers is a modular toolbox that supports both. Our library is designed with a focus on [usability over performance](https://huggingface.co/docs/diffusers/conceptual/philosophy#usability-over-performance), [simple over easy](https://huggingface.co/docs/diffusers/conceptual/philosophy#simple-over-easy), and [customizability over abstractions](https://huggingface.co/docs/diffusers/conceptual/philosophy#tweakable-contributorfriendly-over-abstraction).
|
||||
🤗 Diffusers provides pretrained diffusion models across multiple modalities, such as vision and audio, and serves
|
||||
as a modular toolbox for inference and training of diffusion models.
|
||||
|
||||
🤗 Diffusers offers three core components:
|
||||
More precisely, 🤗 Diffusers offers:
|
||||
|
||||
- State-of-the-art [diffusion pipelines](https://huggingface.co/docs/diffusers/api/pipelines/overview) that can be run in inference with just a few lines of code.
|
||||
- Interchangeable noise [schedulers](https://huggingface.co/docs/diffusers/api/schedulers/overview) for different diffusion speeds and output quality.
|
||||
- Pretrained [models](https://huggingface.co/docs/diffusers/api/models) that can be used as building blocks, and combined with schedulers, for creating your own end-to-end diffusion systems.
|
||||
- State-of-the-art diffusion pipelines that can be run in inference with just a couple of lines of code (see [src/diffusers/pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines)). Check [this overview](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/README.md#pipelines-summary) to see all supported pipelines and their corresponding official papers.
|
||||
- Various noise schedulers that can be used interchangeably for the preferred speed vs. quality trade-off in inference (see [src/diffusers/schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers)).
|
||||
- Multiple types of models, such as UNet, can be used as building blocks in an end-to-end diffusion system (see [src/diffusers/models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models)).
|
||||
- Training examples to show how to train the most popular diffusion model tasks (see [examples](https://github.com/huggingface/diffusers/tree/main/examples), *e.g.* [unconditional-image-generation](https://github.com/huggingface/diffusers/tree/main/examples/unconditional_image_generation)).

## Quickstart
|
||||
## Contributing
|
||||
|
||||
Generating outputs is super easy with 🤗 Diffusers. To generate an image from text, use the `from_pretrained` method to load any pretrained diffusion model (browse the [Hub](https://huggingface.co/models?library=diffusers&sort=downloads) for 4000+ checkpoints):
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16)
|
||||
pipeline.to("cuda")
|
||||
pipeline("An image of a squirrel in Picasso style").images[0]
|
||||
```
|
||||
|
||||
You can also dig into the models and schedulers toolbox to build your own diffusion system:
|
||||
|
||||
```python
|
||||
from diffusers import DDPMScheduler, UNet2DModel
|
||||
from PIL import Image
|
||||
import torch
|
||||
import numpy as np
|
||||
|
||||
scheduler = DDPMScheduler.from_pretrained("google/ddpm-cat-256")
|
||||
model = UNet2DModel.from_pretrained("google/ddpm-cat-256").to("cuda")
|
||||
scheduler.set_timesteps(50)
|
||||
|
||||
sample_size = model.config.sample_size
|
||||
noise = torch.randn((1, 3, sample_size, sample_size)).to("cuda")
|
||||
input = noise
|
||||
|
||||
for t in scheduler.timesteps:
|
||||
with torch.no_grad():
|
||||
noisy_residual = model(input, t).sample
|
||||
prev_noisy_sample = scheduler.step(noisy_residual, t, input).prev_sample
|
||||
input = prev_noisy_sample
|
||||
|
||||
image = (input / 2 + 0.5).clamp(0, 1)
|
||||
image = image.cpu().permute(0, 2, 3, 1).numpy()[0]
|
||||
image = Image.fromarray((image * 255).round().astype("uint8"))
|
||||
image
|
||||
```

## Stable Diffusion is fully compatible with `diffusers`!
|
||||
|
||||
## Popular libraries using 🧨 Diffusers
|
||||
Stable Diffusion is a text-to-image latent diffusion model created by the researchers and engineers from [CompVis](https://github.com/CompVis), [Stability AI](https://stability.ai/), [LAION](https://laion.ai/) and [RunwayML](https://runwayml.com/). It's trained on 512x512 images from a subset of the [LAION-5B](https://laion.ai/blog/laion-5b/) database. This model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 4GB VRAM.
|
||||

You need to accept the model license before downloading or using the Stable Diffusion weights. Please, visit the [model card](https://huggingface.co/runwayml/stable-diffusion-v1-5), read the license carefully and tick the checkbox if you agree. You have to be a registered user in 🤗 Hugging Face Hub, and you'll also need to use an access token for the code to work. For more information on access tokens, please refer to [this section](https://huggingface.co/docs/hub/security-tokens) of the documentation.
|
||||
|
||||
Thank you for using us ❤️
|
||||
|
||||
### Text-to-Image generation with Stable Diffusion
|
||||
|
||||
First let's install
|
||||
```bash
|
||||
pip install --upgrade diffusers transformers scipy
|
||||
```
|
||||
|
||||
Run this command to log in with your HF Hub token if you haven't before (you can skip this step if you prefer to run the model locally, follow [this](#running-the-model-locally) instead)
|
||||
```bash
|
||||
huggingface-cli login
|
||||
```
|
||||
|
||||
We recommend using the model in [half-precision (`fp16`)](https://pytorch.org/blog/accelerating-training-on-nvidia-gpus-with-pytorch-automatic-mixed-precision/) as it gives almost always the same results as full
|
||||
precision while being roughly twice as fast and requiring half the amount of GPU RAM.
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import StableDiffusionPipeline
|
||||
|
||||
pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16, revision="fp16")
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
image = pipe(prompt).images[0]
|
||||
```
|
||||
|
||||
#### Running the model locally
|
||||
If you don't want to login to Hugging Face, you can also simply download the model folder
|
||||
(after having [accepted the license](https://huggingface.co/runwayml/stable-diffusion-v1-5)) and pass
|
||||
the path to the local folder to the `StableDiffusionPipeline`.
|
||||
|
||||
```
|
||||
git lfs install
|
||||
git clone https://huggingface.co/runwayml/stable-diffusion-v1-5
|
||||
```
|
||||
|
||||
Assuming the folder is stored locally under `./stable-diffusion-v1-5`, you can also run stable diffusion
|
||||
without requiring an authentication token:
|
||||
|
||||
```python
|
||||
pipe = StableDiffusionPipeline.from_pretrained("./stable-diffusion-v1-5")
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
image = pipe(prompt).images[0]
|
||||
```
|
||||
|
||||
If you are limited by GPU memory, you might want to consider chunking the attention computation in addition
|
||||
to using `fp16`.
|
||||
The following snippet should result in less than 4GB VRAM.
|
||||
|
||||
```python
|
||||
pipe = StableDiffusionPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5",
|
||||
revision="fp16",
|
||||
torch_dtype=torch.float16,
|
||||
)
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
pipe.enable_attention_slicing()
|
||||
image = pipe(prompt).images[0]
|
||||
```
|
||||
|
||||
If you wish to use a different scheduler (e.g.: DDIM, LMS, PNDM/PLMS), you can instantiate
|
||||
it before the pipeline and pass it to `from_pretrained`.
|
||||
|
||||
```python
|
||||
from diffusers import LMSDiscreteScheduler
|
||||
|
||||
pipe.scheduler = LMSDiscreteScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
image = pipe(prompt).images[0]
|
||||
|
||||
image.save("astronaut_rides_horse.png")
|
||||
```
|
||||
|
||||
If you want to run Stable Diffusion on CPU or you want to have maximum precision on GPU,
|
||||
please run the model in the default *full-precision* setting:
|
||||
|
||||
```python
|
||||
# make sure you're logged in with `huggingface-cli login`
|
||||
from diffusers import StableDiffusionPipeline
|
||||
|
||||
pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5")
|
||||
|
||||
# disable the following line if you run on CPU
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
image = pipe(prompt).images[0]
|
||||
|
||||
image.save("astronaut_rides_horse.png")
|
||||
```
|
||||
|
||||
### JAX/Flax
|
||||
|
||||
Diffusers offers a JAX / Flax implementation of Stable Diffusion for very fast inference. JAX shines specially on TPU hardware because each TPU server has 8 accelerators working in parallel, but it runs great on GPUs too.
|
||||
|
||||
Running the pipeline with the default PNDMScheduler:
|
||||
|
||||
```python
|
||||
import jax
|
||||
import numpy as np
|
||||
from flax.jax_utils import replicate
|
||||
from flax.training.common_utils import shard
|
||||
|
||||
from diffusers import FlaxStableDiffusionPipeline
|
||||
|
||||
pipeline, params = FlaxStableDiffusionPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", revision="flax", dtype=jax.numpy.bfloat16
|
||||
)
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
|
||||
prng_seed = jax.random.PRNGKey(0)
|
||||
num_inference_steps = 50
|
||||
|
||||
num_samples = jax.device_count()
|
||||
prompt = num_samples * [prompt]
|
||||
prompt_ids = pipeline.prepare_inputs(prompt)
|
||||
|
||||
# shard inputs and rng
|
||||
params = replicate(params)
|
||||
prng_seed = jax.random.split(prng_seed, jax.device_count())
|
||||
prompt_ids = shard(prompt_ids)
|
||||
|
||||
images = pipeline(prompt_ids, params, prng_seed, num_inference_steps, jit=True).images
|
||||
images = pipeline.numpy_to_pil(np.asarray(images.reshape((num_samples,) + images.shape[-3:])))
|
||||
```
|
||||
|
||||
**Note**:
|
||||
If you are limited by TPU memory, please make sure to load the `FlaxStableDiffusionPipeline` in `bfloat16` precision instead of the default `float32` precision as done above. You can do so by telling diffusers to load the weights from "bf16" branch.
|
||||
|
||||
```python
|
||||
import jax
|
||||
import numpy as np
|
||||
from flax.jax_utils import replicate
|
||||
from flax.training.common_utils import shard
|
||||
|
||||
from diffusers import FlaxStableDiffusionPipeline
|
||||
|
||||
pipeline, params = FlaxStableDiffusionPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", revision="bf16", dtype=jax.numpy.bfloat16
|
||||
)
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
|
||||
prng_seed = jax.random.PRNGKey(0)
|
||||
num_inference_steps = 50
|
||||
|
||||
num_samples = jax.device_count()
|
||||
prompt = num_samples * [prompt]
|
||||
prompt_ids = pipeline.prepare_inputs(prompt)
|
||||
|
||||
# shard inputs and rng
|
||||
params = replicate(params)
|
||||
prng_seed = jax.random.split(prng_seed, jax.device_count())
|
||||
prompt_ids = shard(prompt_ids)
|
||||
|
||||
images = pipeline(prompt_ids, params, prng_seed, num_inference_steps, jit=True).images
|
||||
images = pipeline.numpy_to_pil(np.asarray(images.reshape((num_samples,) + images.shape[-3:])))
|
||||
```
|
||||
|
||||
### Image-to-Image text-guided generation with Stable Diffusion
|
||||
|
||||
The `StableDiffusionImg2ImgPipeline` lets you pass a text prompt and an initial image to condition the generation of new images.
|
||||
|
||||
```python
|
||||
import requests
|
||||
import torch
|
||||
from PIL import Image
|
||||
from io import BytesIO
|
||||
|
||||
from diffusers import StableDiffusionImg2ImgPipeline
|
||||
|
||||
# load the pipeline
|
||||
device = "cuda"
|
||||
model_id_or_path = "runwayml/stable-diffusion-v1-5"
|
||||
pipe = StableDiffusionImg2ImgPipeline.from_pretrained(
|
||||
model_id_or_path,
|
||||
revision="fp16",
|
||||
torch_dtype=torch.float16,
|
||||
)
|
||||
# or download via git clone https://huggingface.co/runwayml/stable-diffusion-v1-5
|
||||
# and pass `model_id_or_path="./stable-diffusion-v1-5"`.
|
||||
pipe = pipe.to(device)
|
||||
|
||||
# let's download an initial image
|
||||
url = "https://raw.githubusercontent.com/CompVis/stable-diffusion/main/assets/stable-samples/img2img/sketch-mountains-input.jpg"
|
||||
|
||||
response = requests.get(url)
|
||||
init_image = Image.open(BytesIO(response.content)).convert("RGB")
|
||||
init_image = init_image.resize((768, 512))
|
||||
|
||||
prompt = "A fantasy landscape, trending on artstation"
|
||||
|
||||
images = pipe(prompt=prompt, image=init_image, strength=0.75, guidance_scale=7.5).images
|
||||
|
||||
images[0].save("fantasy_landscape.png")
|
||||
```
|
||||
You can also run this example on colab [](https://colab.research.google.com/github/huggingface/notebooks/blob/main/diffusers/image_2_image_using_diffusers.ipynb)
|
||||
|
||||
### In-painting using Stable Diffusion
|
||||
|
||||
The `StableDiffusionInpaintPipeline` lets you edit specific parts of an image by providing a mask and a text prompt. It uses a model optimized for this particular task, whose license you need to accept before use.
|
||||
|
||||
Please, visit the [model card](https://huggingface.co/runwayml/stable-diffusion-inpainting), read the license carefully and tick the checkbox if you agree. Note that this is an additional license, you need to accept it even if you accepted the text-to-image Stable Diffusion license in the past. You have to be a registered user in 🤗 Hugging Face Hub, and you'll also need to use an access token for the code to work. For more information on access tokens, please refer to [this section](https://huggingface.co/docs/hub/security-tokens) of the documentation.
|
||||
|
||||
|
||||
```python
|
||||
import PIL
|
||||
import requests
|
||||
import torch
|
||||
from io import BytesIO
|
||||
|
||||
from diffusers import StableDiffusionInpaintPipeline
|
||||
|
||||
def download_image(url):
|
||||
response = requests.get(url)
|
||||
return PIL.Image.open(BytesIO(response.content)).convert("RGB")
|
||||
|
||||
img_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo.png"
|
||||
mask_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo_mask.png"
|
||||
|
||||
init_image = download_image(img_url).resize((512, 512))
|
||||
mask_image = download_image(mask_url).resize((512, 512))
|
||||
|
||||
pipe = StableDiffusionInpaintPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-inpainting",
|
||||
revision="fp16",
|
||||
torch_dtype=torch.float16,
|
||||
)
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "Face of a yellow cat, high resolution, sitting on a park bench"
|
||||
image = pipe(prompt=prompt, image=init_image, mask_image=mask_image).images[0]
|
||||
```
|
||||
|
||||
### Tweak prompts reusing seeds and latents
|
||||
|
||||
You can generate your own latents to reproduce results, or tweak your prompt on a specific result you liked. [This notebook](https://github.com/pcuenca/diffusers-examples/blob/main/notebooks/stable-diffusion-seeds.ipynb) shows how to do it step by step. You can also run it in Google Colab [](https://colab.research.google.com/github/pcuenca/diffusers-examples/blob/main/notebooks/stable-diffusion-seeds.ipynb).
|
||||
|
||||
|
||||
For more details, check out [the Stable Diffusion notebook](https://colab.research.google.com/github/huggingface/notebooks/blob/main/diffusers/stable_diffusion.ipynb) [](https://colab.research.google.com/github/huggingface/notebooks/blob/main/diffusers/stable_diffusion.ipynb)
|
||||
and have a look into the [release notes](https://github.com/huggingface/diffusers/releases/tag/v0.2.0).

|
||||
## Fine-Tuning Stable Diffusion
|
||||
|
||||
Fine-tuning techniques make it possible to adapt Stable Diffusion to your own dataset, or add new subjects to it. These are some of the techniques supported in `diffusers`:
|
||||
|
||||
Textual Inversion is a technique for capturing novel concepts from a small number of example images in a way that can later be used to control text-to-image pipelines. It does so by learning new 'words' in the embedding space of the pipeline's text encoder. These special words can then be used within text prompts to achieve very fine-grained control of the resulting images.
|
||||
|
||||
- Textual Inversion. Capture novel concepts from a small set of sample images, and associate them with new "words" in the embedding space of the text encoder. Please, refer to [our training examples](https://github.com/huggingface/diffusers/tree/main/examples/textual_inversion) or [documentation](https://huggingface.co/docs/diffusers/training/text_inversion) to try for yourself.

- Dreambooth. Another technique to capture new concepts in Stable Diffusion. This method fine-tunes the UNet (and, optionally, also the text encoder) of the pipeline to achieve impressive results. Please, refer to [our training example](https://github.com/huggingface/diffusers/tree/main/examples/dreambooth) and [training report](https://huggingface.co/blog/dreambooth) for additional details and training recommendations.
|
||||
|
||||
- Full Stable Diffusion fine-tuning. If you have a more sizable dataset with a specific look or style, you can fine-tune Stable Diffusion so that it outputs images following those examples. This was the approach taken to create [a Pokémon Stable Diffusion model](https://huggingface.co/justinpinkney/pokemon-stable-diffusion) (by Justing Pinkney / Lambda Labs), [a Japanese specific version of Stable Diffusion](https://huggingface.co/spaces/rinna/japanese-stable-diffusion) (by [Rinna Co.](https://github.com/rinnakk/japanese-stable-diffusion/) and others. You can start at [our text-to-image fine-tuning example](https://github.com/huggingface/diffusers/tree/main/examples/text_to_image) and go from there.

||||

||||
## Stable Diffusion Community Pipelines
|
||||
|
||||
The release of Stable Diffusion as an open source model has fostered a lot of interesting ideas and experimentation.
|
||||
Our [Community Examples folder](https://github.com/huggingface/diffusers/tree/main/examples/community) contains many ideas worth exploring, like interpolating to create animated videos, using CLIP Guidance for additional prompt fidelity, term weighting, and much more! [Take a look](https://huggingface.co/docs/diffusers/using-diffusers/custom_pipeline_overview) and [contribute your own](https://huggingface.co/docs/diffusers/using-diffusers/contribute_pipeline).
|
||||
|
||||
## Other Examples
|
||||
|
||||
There are many ways to try running Diffusers! Here we outline code-focused tools (primarily using `DiffusionPipeline`s and Google Colab) and interactive web-tools.
|
||||
|
||||
### Running Code
|
||||
|
||||
If you want to run the code yourself 💻, you can try out:

||||
# !pip install diffusers["torch"] transformers
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
device = "cuda"
|
||||
model_id = "CompVis/ldm-text2im-large-256"
|
||||
|
||||
# load model and scheduler
|
||||
ldm = DiffusionPipeline.from_pretrained(model_id)
|
||||
ldm = ldm.to(device)
|
||||
|
||||
# run pipeline in inference (sample random noise and denoise)
|
||||
prompt = "A painting of a squirrel eating a burger"
|
||||
image = ldm([prompt], num_inference_steps=50, eta=0.3, guidance_scale=6).images[0]
|
||||
|
||||
# save image
|
||||
image.save("squirrel.png")

||||
model_id = "google/ddpm-celebahq-256"
|
||||
device = "cuda"
|
||||
|
||||
# load model and scheduler
|
||||
ddpm = DDPMPipeline.from_pretrained(model_id) # you can replace DDPMPipeline with DDIMPipeline or PNDMPipeline for faster inference
|
||||
ddpm.to(device)
|
||||
|
||||
# run pipeline in inference (sample random noise and denoise)
|
||||
image = ddpm().images[0]

## Philosophy
|
||||
|
||||
- Readability and clarity is preferred over highly optimized code. A strong importance is put on providing readable, intuitive and elementary code design. *E.g.*, the provided [schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers) are separated from the provided [models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models) and provide well-commented code that can be read alongside the original paper.
|
||||
- Diffusers is **modality independent** and focuses on providing pretrained models and tools to build systems that generate **continuous outputs**, *e.g.* vision and audio.
|
||||
- Diffusion models and schedulers are provided as concise, elementary building blocks. In contrast, diffusion pipelines are a collection of end-to-end diffusion systems that can be used out-of-the-box, should stay as close as possible to their original implementation and can include components of another library, such as text-encoders. Examples for diffusion pipelines are [Glide](https://github.com/openai/glide-text2im) and [Latent Diffusion](https://github.com/CompVis/latent-diffusion).
|
||||
|
||||
## In the works
|
||||
|
||||
For the first release, 🤗 Diffusers focuses on text-to-image diffusion techniques. However, diffusers can be used for much more than that! Over the upcoming releases, we'll be focusing on:
|
||||
|
||||
- Diffusers for audio
|
||||
- Diffusers for reinforcement learning (initial work happening in https://github.com/huggingface/diffusers/pull/105).
|
||||
- Diffusers for video generation
|
||||
- Diffusers for molecule generation (initial work happening in https://github.com/huggingface/diffusers/pull/54)
|
||||
|
||||
A few pipeline components are already being worked on, namely:
|
||||
|
||||
- BDDMPipeline for spectrogram-to-sound vocoding
|
||||
- GLIDEPipeline to support OpenAI's GLIDE model
|
||||
- Grad-TTS for text to audio generation / conditional audio generation
|
||||
|
||||
We want diffusers to be a toolbox useful for diffusers models in general; if you find yourself limited in any way by the current API, or would like to see additional models, schedulers, or techniques, please open a [GitHub issue](https://github.com/huggingface/diffusers/issues) mentioning what you would like to see.

# Generating the documentation
|
||||
|
||||
To generate the documentation, you first have to build it. Several packages are necessary to build the doc,
|
||||
you can install them with the following command, at the root of the code repository:
|
||||
|
||||
```bash
|
||||
pip install -e ".[docs]"
|
||||
```
|
||||
|
||||
Then you need to install our open source documentation builder tool:
|
||||
|
||||
```bash
|
||||
pip install git+https://github.com/huggingface/doc-builder
|
||||
```
|
||||
|
||||
---
|
||||
**NOTE**
|
||||
|
||||
You only need to generate the documentation to inspect it locally (if you're planning changes and want to
|
||||
check how they look before committing for instance). You don't have to commit the built documentation.
|
||||
|
||||
---
|
||||
|
||||
## Previewing the documentation
|
||||
|
||||
To preview the docs, first install the `watchdog` module with:
|
||||
|
||||
```bash
|
||||
pip install watchdog
|
||||
```
|
||||
|
||||
Then run the following command:
|
||||
|
||||
```bash
|
||||
doc-builder preview {package_name} {path_to_docs}
|
||||
```
|
||||
|
||||
For example:
|
||||
|
||||
```bash
|
||||
doc-builder preview diffusers docs/source/en
|
||||
```
|
||||
|
||||
The docs will be viewable at [http://localhost:3000](http://localhost:3000). You can also preview the docs once you have opened a PR. You will see a bot add a comment to a link where the documentation with your changes lives.
|
||||
|
||||
---
|
||||
**NOTE**
|
||||
|
||||
The `preview` command only works with existing doc files. When you add a completely new file, you need to update `_toctree.yml` & restart `preview` command (`ctrl-c` to stop it & call `doc-builder preview ...` again).
|
||||
|
||||
---
|
||||
|
||||
## Adding a new element to the navigation bar
|
||||
|
||||
Accepted files are Markdown (.md).
|
||||
|
||||
Create a file with its extension and put it in the source directory. You can then link it to the toc-tree by putting
|
||||
the filename without the extension in the [`_toctree.yml`](https://github.com/huggingface/diffusers/blob/main/docs/source/_toctree.yml) file.
|
||||
|
||||
## Renaming section headers and moving sections
|
||||
|
||||
It helps to keep the old links working when renaming the section header and/or moving sections from one document to another. This is because the old links are likely to be used in Issues, Forums, and Social media and it'd make for a much more superior user experience if users reading those months later could still easily navigate to the originally intended information.
|
||||
|
||||
Therefore, we simply keep a little map of moved sections at the end of the document where the original section was. The key is to preserve the original anchor.
|
||||
|
||||
So if you renamed a section from: "Section A" to "Section B", then you can add at the end of the file:
|
||||
|
||||
```
|
||||
Sections that were moved:
|
||||
|
||||
[ <a href="#section-b">Section A</a><a id="section-a"></a> ]
|
||||
```
|
||||
and of course, if you moved it to another file, then:
|
||||
|
||||
```
|
||||
Sections that were moved:
|
||||
|
||||
[ <a href="../new-file#section-b">Section A</a><a id="section-a"></a> ]
|
||||
```
|
||||
|
||||
Use the relative style to link to the new file so that the versioned docs continue to work.
|
||||
|
||||
For an example of a rich moved section set please see the very end of [the transformers Trainer doc](https://github.com/huggingface/transformers/blob/main/docs/source/en/main_classes/trainer.md).
|
||||
|
||||
|
||||
## Writing Documentation - Specification
|
||||
|
||||
The `huggingface/diffusers` documentation follows the
|
||||
[Google documentation](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html) style for docstrings,
|
||||
although we can write them directly in Markdown.
|
||||
|
||||
### Adding a new tutorial
|
||||
|
||||
Adding a new tutorial or section is done in two steps:
|
||||
|
||||
- Add a new file under `docs/source`. This file can either be ReStructuredText (.rst) or Markdown (.md).
|
||||
- Link that file in `docs/source/_toctree.yml` on the correct toc-tree.
|
||||
|
||||
Make sure to put your new file under the proper section. It's unlikely to go in the first section (*Get Started*), so
|
||||
depending on the intended targets (beginners, more advanced users, or researchers) it should go in sections two, three, or four.
|
||||
|
||||
### Adding a new pipeline/scheduler
|
||||
|
||||
When adding a new pipeline:
|
||||
|
||||
- create a file `xxx.md` under `docs/source/api/pipelines` (don't hesitate to copy an existing file as template).
|
||||
- Link that file in (*Diffusers Summary*) section in `docs/source/api/pipelines/overview.md`, along with the link to the paper, and a colab notebook (if available).
|
||||
- Write a short overview of the diffusion model:
|
||||
- Overview with paper & authors
|
||||
- Paper abstract
|
||||
- Tips and tricks and how to use it best
|
||||
- Possible an end-to-end example of how to use it
|
||||
- Add all the pipeline classes that should be linked in the diffusion model. These classes should be added using our Markdown syntax. By default as follows:
|
||||
|
||||
```
|
||||
## XXXPipeline
|
||||
|
||||
[[autodoc]] XXXPipeline
|
||||
- all
|
||||
- __call__
|
||||
```
|
||||
|
||||
This will include every public method of the pipeline that is documented, as well as the `__call__` method that is not documented by default. If you just want to add additional methods that are not documented, you can put the list of all methods to add in a list that contains `all`.
|
||||
|
||||
```
|
||||
[[autodoc]] XXXPipeline
|
||||
- all
|
||||
- __call__
|
||||
- enable_attention_slicing
|
||||
- disable_attention_slicing
|
||||
- enable_xformers_memory_efficient_attention
|
||||
- disable_xformers_memory_efficient_attention
|
||||
```
|
||||
|
||||
You can follow the same process to create a new scheduler under the `docs/source/api/schedulers` folder
|
||||
|
||||
### Writing source documentation
|
||||
|
||||
Values that should be put in `code` should either be surrounded by backticks: \`like so\`. Note that argument names
|
||||
and objects like True, None, or any strings should usually be put in `code`.
|
||||
|
||||
When mentioning a class, function, or method, it is recommended to use our syntax for internal links so that our tool
|
||||
adds a link to its documentation with this syntax: \[\`XXXClass\`\] or \[\`function\`\]. This requires the class or
|
||||
function to be in the main package.
|
||||
|
||||
If you want to create a link to some internal class or function, you need to
|
||||
provide its path. For instance: \[\`pipelines.ImagePipelineOutput\`\]. This will be converted into a link with
|
||||
`pipelines.ImagePipelineOutput` in the description. To get rid of the path and only keep the name of the object you are
|
||||
linking to in the description, add a ~: \[\`~pipelines.ImagePipelineOutput\`\] will generate a link with `ImagePipelineOutput` in the description.
|
||||
|
||||
The same works for methods so you can either use \[\`XXXClass.method\`\] or \[~\`XXXClass.method\`\].
|
||||
|
||||
#### Defining arguments in a method
|
||||
|
||||
Arguments should be defined with the `Args:` (or `Arguments:` or `Parameters:`) prefix, followed by a line return and
|
||||
an indentation. The argument should be followed by its type, with its shape if it is a tensor, a colon, and its
|
||||
description:
|
||||
|
||||
```
|
||||
Args:
|
||||
n_layers (`int`): The number of layers of the model.
|
||||
```
|
||||
|
||||
If the description is too long to fit in one line, another indentation is necessary before writing the description
|
||||
after the argument.
|
||||
|
||||
Here's an example showcasing everything so far:
|
||||
|
||||
```
|
||||
Args:
|
||||
input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`):
|
||||
Indices of input sequence tokens in the vocabulary.
|
||||
|
||||
Indices can be obtained using [`AlbertTokenizer`]. See [`~PreTrainedTokenizer.encode`] and
|
||||
[`~PreTrainedTokenizer.__call__`] for details.
|
||||
|
||||
[What are input IDs?](../glossary#input-ids)
|
||||
```
|
||||
|
||||
For optional arguments or arguments with defaults we follow the following syntax: imagine we have a function with the
|
||||
following signature:
|
||||
|
||||
```
|
||||
def my_function(x: str = None, a: float = 1):
|
||||
```
|
||||
|
||||
then its documentation should look like this:
|
||||
|
||||
```
|
||||
Args:
|
||||
x (`str`, *optional*):
|
||||
This argument controls ...
|
||||
a (`float`, *optional*, defaults to 1):
|
||||
This argument is used to ...
|
||||
```
|
||||
|
||||
Note that we always omit the "defaults to \`None\`" when None is the default for any argument. Also note that even
|
||||
if the first line describing your argument type and its default gets long, you can't break it on several lines. You can
|
||||
however write as many lines as you want in the indented description (see the example above with `input_ids`).
|
||||
|
||||
#### Writing a multi-line code block
|
||||
|
||||
Multi-line code blocks can be useful for displaying examples. They are done between two lines of three backticks as usual in Markdown:
|
||||
|
||||
|
||||
````
|
||||
```
|
||||
# first line of code
|
||||
# second line
|
||||
# etc
|
||||
```
|
||||
````
|
||||
|
||||
#### Writing a return block
|
||||
|
||||
The return block should be introduced with the `Returns:` prefix, followed by a line return and an indentation.
|
||||
The first line should be the type of the return, followed by a line return. No need to indent further for the elements
|
||||
building the return.
|
||||
|
||||
Here's an example of a single value return:
|
||||
|
||||
```
|
||||
Returns:
|
||||
`List[int]`: A list of integers in the range [0, 1] --- 1 for a special token, 0 for a sequence token.
|
||||
```
|
||||
|
||||
Here's an example of a tuple return, comprising several objects:
|
||||
|
||||
```
|
||||
Returns:
|
||||
`tuple(torch.FloatTensor)` comprising various elements depending on the configuration ([`BertConfig`]) and inputs:
|
||||
- ** loss** (*optional*, returned when `masked_lm_labels` is provided) `torch.FloatTensor` of shape `(1,)` --
|
||||
Total loss is the sum of the masked language modeling loss and the next sequence prediction (classification) loss.
|
||||
- **prediction_scores** (`torch.FloatTensor` of shape `(batch_size, sequence_length, config.vocab_size)`) --
|
||||
Prediction scores of the language modeling head (scores for each vocabulary token before SoftMax).
|
||||
```
|
||||
|
||||
#### Adding an image
|
||||
|
||||
Due to the rapidly growing repository, it is important to make sure that no files that would significantly weigh down the repository are added. This includes images, videos, and other non-text files. We prefer to leverage a hf.co hosted `dataset` like
|
||||
the ones hosted on [`hf-internal-testing`](https://huggingface.co/hf-internal-testing) in which to place these files and reference
|
||||
them by URL. We recommend putting them in the following dataset: [huggingface/documentation-images](https://huggingface.co/datasets/huggingface/documentation-images).
|
||||
If an external contribution, feel free to add the images to your PR and ask a Hugging Face member to migrate your images
|
||||
to this dataset.
|
||||
|
||||
## Styling the docstring
|
||||
|
||||
We have an automatic script running with the `make style` command that will make sure that:
|
||||
- the docstrings fully take advantage of the line width
|
||||
- all code examples are formatted using black, like the code of the Transformers library
|
||||
|
||||
This script may have some weird failures if you made a syntax mistake or if you uncover a bug. Therefore, it's
|
||||
recommended to commit your changes before running `make style`, so you can revert the changes done by that script
|
||||
easily.

### Translating the Diffusers documentation into your language
|
||||
|
||||
As part of our mission to democratize machine learning, we'd love to make the Diffusers library available in many more languages! Follow the steps below if you want to help translate the documentation into your language 🙏.
|
||||
|
||||
**🗞️ Open an issue**
|
||||
|
||||
To get started, navigate to the [Issues](https://github.com/huggingface/diffusers/issues) page of this repo and check if anyone else has opened an issue for your language. If not, open a new issue by selecting the "Translation template" from the "New issue" button.
|
||||
|
||||
Once an issue exists, post a comment to indicate which chapters you'd like to work on, and we'll add your name to the list.
|
||||
|
||||
|
||||
**🍴 Fork the repository**
|
||||
|
||||
First, you'll need to [fork the Diffusers repo](https://docs.github.com/en/get-started/quickstart/fork-a-repo). You can do this by clicking on the **Fork** button on the top-right corner of this repo's page.
|
||||
|
||||
Once you've forked the repo, you'll want to get the files on your local machine for editing. You can do that by cloning the fork with Git as follows:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/YOUR-USERNAME/diffusers.git
|
||||
```
|
||||
|
||||
**📋 Copy-paste the English version with a new language code**
|
||||
|
||||
The documentation files are in one leading directory:
|
||||
|
||||
- [`docs/source`](https://github.com/huggingface/diffusers/tree/main/docs/source): All the documentation materials are organized here by language.
|
||||
|
||||
You'll only need to copy the files in the [`docs/source/en`](https://github.com/huggingface/diffusers/tree/main/docs/source/en) directory, so first navigate to your fork of the repo and run the following:
|
||||
|
||||
```bash
|
||||
cd ~/path/to/diffusers/docs
|
||||
cp -r source/en source/LANG-ID
|
||||
```
|
||||
|
||||
Here, `LANG-ID` should be one of the ISO 639-1 or ISO 639-2 language codes -- see [here](https://www.loc.gov/standards/iso639-2/php/code_list.php) for a handy table.
|
||||
|
||||
**✍️ Start translating**
|
||||
|
||||
The fun part comes - translating the text!
|
||||
|
||||
The first thing we recommend is translating the part of the `_toctree.yml` file that corresponds to your doc chapter. This file is used to render the table of contents on the website.
|
||||
|
||||
> 🙋 If the `_toctree.yml` file doesn't yet exist for your language, you can create one by copy-pasting from the English version and deleting the sections unrelated to your chapter. Just make sure it exists in the `docs/source/LANG-ID/` directory!
|
||||
|
||||
The fields you should add are `local` (with the name of the file containing the translation; e.g. `autoclass_tutorial`), and `title` (with the title of the doc in your language; e.g. `Load pretrained instances with an AutoClass`) -- as a reference, here is the `_toctree.yml` for [English](https://github.com/huggingface/diffusers/blob/main/docs/source/en/_toctree.yml):
|
||||
|
||||
```yaml
|
||||
- sections:
|
||||
- local: pipeline_tutorial # Do not change this! Use the same name for your .md file
|
||||
title: Pipelines for inference # Translate this!
|
||||
...
|
||||
title: Tutorials # Translate this!
|
||||
```
|
||||
|
||||
Once you have translated the `_toctree.yml` file, you can start translating the [MDX](https://mdxjs.com/) files associated with your docs chapter.
|
||||
|
||||
> 🙋 If you'd like others to help you with the translation, you should [open an issue](https://github.com/huggingface/diffusers/issues) and tag @patrickvonplaten.

# Pipelines
|
||||
|
||||
The [`DiffusionPipeline`] is the easiest way to load any pretrained diffusion pipeline from the [Hub](https://huggingface.co/models?library=diffusers) and to use it in inference.
|
||||
|
||||
<Tip>
|
||||
|
||||
One should not use the Diffusion Pipeline class for training or fine-tuning a diffusion model. Individual
|
||||
components of diffusion pipelines are usually trained individually, so we suggest to directly work
|
||||
with [`UNetModel`] and [`UNetConditionModel`].
|
||||
|
||||
</Tip>
|
||||
|
||||
Any diffusion pipeline that is loaded with [`~DiffusionPipeline.from_pretrained`] will automatically
|
||||
detect the pipeline type, *e.g.* [`StableDiffusionPipeline`] and consequently load each component of the
|
||||
pipeline and pass them into the `__init__` function of the pipeline, *e.g.* [`~StableDiffusionPipeline.__init__`].
|
||||
|
||||
Any pipeline object can be saved locally with [`~DiffusionPipeline.save_pretrained`].

[`logging.get_verbosity`] to get the current level of verbosity in the logger and
|
||||
[`logging.set_verbosity`] to set the verbosity to the level of your choice.
|
||||
[`logging.set_verbosity`] to set the verbosity to the level of your choice. In order (from the least
|
||||
verbose to the most verbose), those levels (with their corresponding int values in parenthesis) are:
|
||||
|
||||
In order from the least verbose to the most verbose:
|
||||
- `diffusers.logging.CRITICAL` or `diffusers.logging.FATAL` (int value, 50): only report the most
|
||||
critical errors.
|
||||
- `diffusers.logging.ERROR` (int value, 40): only report errors.
|
||||
- `diffusers.logging.WARNING` or `diffusers.logging.WARN` (int value, 30): only reports error and
|
||||
warnings. This the default level used by the library.
|
||||
- `diffusers.logging.INFO` (int value, 20): reports error, warnings and basic information.
|
||||
- `diffusers.logging.DEBUG` (int value, 10): report all information.
|
||||
|
||||
| Method | Integer value | Description |
|
||||
|----------------------------------------------------------:|--------------:|----------------------------------------------------:|
|
||||
| `diffusers.logging.CRITICAL` or `diffusers.logging.FATAL` | 50 | only report the most critical errors |
|
||||
| `diffusers.logging.ERROR` | 40 | only report errors |
|
||||
| `diffusers.logging.WARNING` or `diffusers.logging.WARN` | 30 | only report errors and warnings (default) |
|
||||
| `diffusers.logging.INFO` | 20 | only report errors, warnings, and basic information |
|
||||
| `diffusers.logging.DEBUG` | 10 | report all information |
|
||||
|
||||
By default, `tqdm` progress bars are displayed during model download. [`logging.disable_progress_bar`] and [`logging.enable_progress_bar`] are used to enable or disable this behavior.
|
||||
By default, `tqdm` progress bars will be displayed during model download. [`logging.disable_progress_bar`] and [`logging.enable_progress_bar`] can be used to suppress or unsuppress this behavior.

# Models
|
||||
|
||||
Diffusers contains pretrained models for popular algorithms and modules for creating the next set of diffusion models.
|
||||
The primary function of these models is to denoise an input sample, by modeling the distribution $p_\theta(\mathbf{x}_{t-1}|\mathbf{x}_t)$.
|
||||
The models are built on the base class ['ModelMixin'] that is a `torch.nn.module` with basic functionality for saving and loading models both locally and from the HuggingFace hub.

# BaseOutputs
|
||||
|
||||
All models have outputs that are instances of subclasses of [`~utils.BaseOutput`]. Those are
|
||||
data structures containing all the information returned by the model, but that can also be used as tuples or
|
||||
dictionaries.
|
||||
|
||||
Let's see how this looks in an example:
|
||||
|
||||
```python
|
||||
from diffusers import DDIMPipeline
|
||||
|
||||
pipeline = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32")
|
||||
outputs = pipeline()
|
||||
```
|
||||
|
||||
The `outputs` object is a [`~pipeline_utils.ImagePipelineOutput`], as we can see in the
|
||||
documentation of that class below, it means it has an image attribute.
|
||||
|
||||
You can access each attribute as you would usually do, and if that attribute has not been returned by the model, you will get `None`:
|
||||
|
||||
```python
|
||||
outputs.images
|
||||
```
|
||||
|
||||
or via keyword lookup
|
||||
|
||||
```python
|
||||
outputs["images"]
|
||||
```
|
||||
|
||||
When considering our `outputs` object as tuple, it only considers the attributes that don't have `None` values.
|
||||
Here for instance, we could retrieve images via indexing:
|
||||
|
||||
```python
|
||||
outputs[:1]
|
||||
```
|
||||
|
||||
which will return the tuple `(outputs.images)` for instance.
|
||||
|
||||

# AltDiffusion
|
||||
|
||||
AltDiffusion was proposed in [AltCLIP: Altering the Language Encoder in CLIP for Extended Language Capabilities](https://arxiv.org/abs/2211.06679) by Zhongzhi Chen, Guang Liu, Bo-Wen Zhang, Fulong Ye, Qinghong Yang, Ledell Wu
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*In this work, we present a conceptually simple and effective method to train a strong bilingual multimodal representation model. Starting from the pretrained multimodal representation model CLIP released by OpenAI, we switched its text encoder with a pretrained multilingual text encoder XLM-R, and aligned both languages and image representations by a two-stage training schema consisting of teacher learning and contrastive learning. We validate our method through evaluations of a wide range of tasks. We set new state-of-the-art performances on a bunch of tasks including ImageNet-CN, Flicker30k- CN, and COCO-CN. Further, we obtain very close performances with CLIP on almost all tasks, suggesting that one can simply alter the text encoder in CLIP for extended capabilities such as multilingual understanding.*
|
||||
|
||||
|
||||
*Overview*:

||||

||||

|
||||

||||

|
||||
|
||||
## Tips
|
||||
|
||||
- AltDiffusion is conceptually exaclty the same as [Stable Diffusion](./api/pipelines/stable_diffusion).
|
||||
|
||||
- *Run AltDiffusion*
|
||||
|
||||
AltDiffusion can be tested very easily with the [`AltDiffusionPipeline`], [`AltDiffusionImg2ImgPipeline`] and the `"BAAI/AltDiffusion-m9"` checkpoint exactly in the same way it is shown in the [Conditional Image Generation Guide](./using-diffusers/conditional_image_generation) and the [Image-to-Image Generation Guide](./using-diffusers/img2img).
|
||||
|
||||
- *How to load and use different schedulers.*
|
||||
|
||||
The alt diffusion pipeline uses [`DDIMScheduler`] scheduler by default. But `diffusers` provides many other schedulers that can be used with the alt diffusion pipeline such as [`PNDMScheduler`], [`LMSDiscreteScheduler`], [`EulerDiscreteScheduler`], [`EulerAncestralDiscreteScheduler`] etc.
|
||||
To use a different scheduler, you can either change it via the [`ConfigMixin.from_config`] method or pass the `scheduler` argument to the `from_pretrained` method of the pipeline. For example, to use the [`EulerDiscreteScheduler`], you can do the following:
|
||||
|
||||
```python
|
||||
>>> from diffusers import AltDiffusionPipeline, EulerDiscreteScheduler
|
||||
|
||||
>>> pipeline = AltDiffusionPipeline.from_pretrained("BAAI/AltDiffusion-m9")
|
||||
>>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
|
||||
|
||||
>>> # or
|
||||
>>> euler_scheduler = EulerDiscreteScheduler.from_pretrained("BAAI/AltDiffusion-m9", subfolder="scheduler")
|
||||
>>> pipeline = AltDiffusionPipeline.from_pretrained("BAAI/AltDiffusion-m9", scheduler=euler_scheduler)
|
||||
```
|
||||
|
||||
|
||||
- *How to convert all use cases with multiple or single pipeline*
|
||||
|
||||
If you want to use all possible use cases in a single `DiffusionPipeline` we recommend using the `components` functionality to instantiate all components in the most memory-efficient way:
|
||||
|
||||
```python
|
||||
>>> from diffusers import (
|
||||
... AltDiffusionPipeline,
|
||||
... AltDiffusionImg2ImgPipeline,
|
||||
... )
|
||||
|
||||
>>> text2img = AltDiffusionPipeline.from_pretrained("BAAI/AltDiffusion-m9")
|
||||
>>> img2img = AltDiffusionImg2ImgPipeline(**text2img.components)
|
||||
|
||||
>>> # now you can use text2img(...) and img2img(...) just like the call methods of each respective pipeline
|
||||
```

# Cycle Diffusion
|
||||
|
||||
## Overview
|
||||
|
||||
Cycle Diffusion is a Text-Guided Image-to-Image Generation model proposed in [Unifying Diffusion Models' Latent Space, with Applications to CycleDiffusion and Guidance](https://arxiv.org/abs/2210.05559) by Chen Henry Wu, Fernando De la Torre.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*Diffusion models have achieved unprecedented performance in generative modeling. The commonly-adopted formulation of the latent code of diffusion models is a sequence of gradually denoised samples, as opposed to the simpler (e.g., Gaussian) latent space of GANs, VAEs, and normalizing flows. This paper provides an alternative, Gaussian formulation of the latent space of various diffusion models, as well as an invertible DPM-Encoder that maps images into the latent space. While our formulation is purely based on the definition of diffusion models, we demonstrate several intriguing consequences. (1) Empirically, we observe that a common latent space emerges from two diffusion models trained independently on related domains. In light of this finding, we propose CycleDiffusion, which uses DPM-Encoder for unpaired image-to-image translation. Furthermore, applying CycleDiffusion to text-to-image diffusion models, we show that large-scale text-to-image diffusion models can be used as zero-shot image-to-image editors. (2) One can guide pre-trained diffusion models and GANs by controlling the latent codes in a unified, plug-and-play formulation based on energy-based models. Using the CLIP model and a face recognition model as guidance, we demonstrate that diffusion models have better coverage of low-density sub-populations and individuals than GANs.*
|
||||
|
||||
*Tips*:
|
||||
- The Cycle Diffusion pipeline is fully compatible with any [Stable Diffusion](./stable_diffusion) checkpoints
|
||||
- Currently Cycle Diffusion only works with the [`DDIMScheduler`].
|
||||
|
||||

# DDIM
|
||||
|
||||
## Overview
|
||||
|
||||
[Denoising Diffusion Implicit Models](https://arxiv.org/abs/2010.02502) (DDIM) by Jiaming Song, Chenlin Meng and Stefano Ermon.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
Denoising diffusion probabilistic models (DDPMs) have achieved high quality image generation without adversarial training, yet they require simulating a Markov chain for many steps to produce a sample. To accelerate sampling, we present denoising diffusion implicit models (DDIMs), a more efficient class of iterative implicit probabilistic models with the same training procedure as DDPMs. In DDPMs, the generative process is defined as the reverse of a Markovian diffusion process. We construct a class of non-Markovian diffusion processes that lead to the same training objective, but whose reverse process can be much faster to sample from. We empirically demonstrate that DDIMs can produce high quality samples 10× to 50× faster in terms of wall-clock time compared to DDPMs, allow us to trade off computation for sample quality, and can perform semantically meaningful image interpolation directly in the latent space.

# DDPM
|
||||
|
||||
## Overview
|
||||
|
||||
[Denoising Diffusion Probabilistic Models](https://arxiv.org/abs/2006.11239)
|
||||
(DDPM) by Jonathan Ho, Ajay Jain and Pieter Abbeel proposes the diffusion based model of the same name, but in the context of the 🤗 Diffusers library, DDPM refers to the discrete denoising scheduler from the paper as well as the pipeline.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
We present high quality image synthesis results using diffusion probabilistic models, a class of latent variable models inspired by considerations from nonequilibrium thermodynamics. Our best results are obtained by training on a weighted variational bound designed according to a novel connection between diffusion probabilistic models and denoising score matching with Langevin dynamics, and our models naturally admit a progressive lossy decompression scheme that can be interpreted as a generalization of autoregressive decoding. On the unconditional CIFAR10 dataset, we obtain an Inception score of 9.46 and a state-of-the-art FID score of 3.17. On 256x256 LSUN, we obtain sample quality similar to ProgressiveGAN.

# Latent Diffusion

|

|
||||
The abstract of the paper is the following:
|
||||
|
||||
*By decomposing the image formation process into a sequential application of denoising autoencoders, diffusion models (DMs) achieve state-of-the-art synthesis results on image data and beyond. Additionally, their formulation allows for a guiding mechanism to control the image generation process without retraining. However, since these models typically operate directly in pixel space, optimization of powerful DMs often consumes hundreds of GPU days and inference is expensive due to sequential evaluations. To enable DM training on limited computational resources while retaining their quality and flexibility, we apply them in the latent space of powerful pretrained autoencoders. In contrast to previous work, training diffusion models on such a representation allows for the first time to reach a near-optimal point between complexity reduction and detail preservation, greatly boosting visual fidelity. By introducing cross-attention layers into the model architecture, we turn diffusion models into powerful and flexible generators for general conditioning inputs such as text or bounding boxes and high-resolution synthesis becomes possible in a convolutional manner. Our latent diffusion models (LDMs) achieve a new state of the art for image inpainting and highly competitive performance on various tasks, including unconditional image generation, semantic scene synthesis, and super-resolution, while significantly reducing computational requirements compared to pixel-based DMs.*

# Pipelines
|
||||
|
||||
Pipelines provide a simple way to run state-of-the-art diffusion models in inference.
|
||||
Most diffusion systems consist of multiple independently-trained models and highly adaptable scheduler
|
||||
components - all of which are needed to have a functioning end-to-end diffusion system.
|
||||
|
||||
As an example, [Stable Diffusion](https://huggingface.co/blog/stable_diffusion) has three independently trained models:
|
||||
- [Autoencoder](./api/models#vae)
|
||||
- [Conditional Unet](./api/models#UNet2DConditionModel)
|
||||
- [CLIP text encoder](https://huggingface.co/docs/transformers/v4.21.2/en/model_doc/clip#transformers.CLIPTextModel)
|
||||
- a scheduler component, [scheduler](./api/scheduler#pndm),
|
||||
- a [CLIPFeatureExtractor](https://huggingface.co/docs/transformers/v4.21.2/en/model_doc/clip#transformers.CLIPFeatureExtractor),
|
||||
- as well as a [safety checker](./stable_diffusion#safety_checker).
|
||||
All of these components are necessary to run stable diffusion in inference even though they were trained
|
||||
or created independently from each other.
|
||||
|
||||
To that end, we strive to offer all open-sourced, state-of-the-art diffusion system under a unified API.
|
||||
More specifically, we strive to provide pipelines that
|
||||
- 1. can load the officially published weights and yield 1-to-1 the same outputs as the original implementation according to the corresponding paper (*e.g.* [LDMTextToImagePipeline](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/latent_diffusion), uses the officially released weights of [High-Resolution Image Synthesis with Latent Diffusion Models](https://arxiv.org/abs/2112.10752)),
|
||||
- 2. have a simple user interface to run the model in inference (see the [Pipelines API](#pipelines-api) section),
|
||||
- 3. are easy to understand with code that is self-explanatory and can be read along-side the official paper (see [Pipelines summary](#pipelines-summary)),
|
||||
- 4. can easily be contributed by the community (see the [Contribution](#contribution) section).
|
||||
|
||||
**Note** that pipelines do not (and should not) offer any training functionality.
|
||||
If you are looking for *official* training examples, please have a look at [examples](https://github.com/huggingface/diffusers/tree/main/examples).

|
||||
|
||||
**Note**: Pipelines are simple examples of how to play around with the diffusion systems as described in the corresponding papers.
|
||||
|
||||
However, most of them can be adapted to use different scheduler components or even different model components. Some pipeline examples are shown in the [Examples](#examples) below.
|
||||
|
||||
## Pipelines API
|
||||
|
||||
Diffusion models often consist of multiple independently-trained models or other previously existing components.
|
||||
|
||||
|
||||
Each model has been trained independently on a different task and the scheduler can easily be swapped out and replaced with a different one.
|
||||
During inference, we however want to be able to easily load all components and use them in inference - even if one component, *e.g.* CLIP's text encoder, originates from a different library, such as [Transformers](https://github.com/huggingface/transformers). To that end, all pipelines provide the following functionality:
|
||||
|
||||
- [`from_pretrained` method](../diffusion_pipeline) that accepts a Hugging Face Hub repository id, *e.g.* [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) or a path to a local directory, *e.g.*
|
||||
"./stable-diffusion". To correctly retrieve which models and components should be loaded, one has to provide a `model_index.json` file, *e.g.* [runwayml/stable-diffusion-v1-5/model_index.json](https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/model_index.json), which defines all components that should be
|
||||
loaded into the pipelines. More specifically, for each model/component one needs to define the format `<name>: ["<library>", "<class name>"]`. `<name>` is the attribute name given to the loaded instance of `<class name>` which can be found in the library or pipeline folder called `"<library>"`.
|
||||
- [`save_pretrained`](../diffusion_pipeline) that accepts a local path, *e.g.* `./stable-diffusion` under which all models/components of the pipeline will be saved. For each component/model a folder is created inside the local path that is named after the given attribute name, *e.g.* `./stable_diffusion/unet`.
|
||||
In addition, a `model_index.json` file is created at the root of the local path, *e.g.* `./stable_diffusion/model_index.json` so that the complete pipeline can again be instantiated
|
||||
from the local path.
|
||||
- [`to`](../diffusion_pipeline) which accepts a `string` or `torch.device` to move all models that are of type `torch.nn.Module` to the passed device. The behavior is fully analogous to [PyTorch's `to` method](https://pytorch.org/docs/stable/generated/torch.nn.Module.html#torch.nn.Module.to).
|
||||
- [`__call__`] method to use the pipeline in inference. `__call__` defines inference logic of the pipeline and should ideally encompass all aspects of it, from pre-processing to forwarding tensors to the different models and schedulers, as well as post-processing. The API of the `__call__` method can strongly vary from pipeline to pipeline. *E.g.* a text-to-image pipeline, such as [`StableDiffusionPipeline`](./stable_diffusion) should accept among other things the text prompt to generate the image. A pure image generation pipeline, such as [DDPMPipeline](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/ddpm) on the other hand can be run without providing any inputs. To better understand what inputs can be adapted for
|
||||
each pipeline, one should look directly into the respective pipeline.
|
||||
|
||||
**Note**: All pipelines have PyTorch's autograd disabled by decorating the `__call__` method with a [`torch.no_grad`](https://pytorch.org/docs/stable/generated/torch.no_grad.html) decorator because pipelines should
|
||||
not be used for training. If you want to store the gradients during the forward pass, we recommend writing your own pipeline, see also our [community-examples](https://github.com/huggingface/diffusers/tree/main/examples/community)
|
||||
|
||||
## Contribution
|
||||
|
||||
We are more than happy about any contribution to the officially supported pipelines 🤗. We aspire
|
||||
all of our pipelines to be **self-contained**, **easy-to-tweak**, **beginner-friendly** and for **one-purpose-only**.
|
||||
|
||||
- **Self-contained**: A pipeline shall be as self-contained as possible. More specifically, this means that all functionality should be either directly defined in the pipeline file itself, should be inherited from (and only from) the [`DiffusionPipeline` class](.../diffusion_pipeline) or be directly attached to the model and scheduler components of the pipeline.
|
||||
- **Easy-to-use**: Pipelines should be extremely easy to use - one should be able to load the pipeline and
|
||||
use it for its designated task, *e.g.* text-to-image generation, in just a couple of lines of code. Most
|
||||
logic including pre-processing, an unrolled diffusion loop, and post-processing should all happen inside the `__call__` method.
|
||||
- **Easy-to-tweak**: Certain pipelines will not be able to handle all use cases and tasks that you might like them to. If you want to use a certain pipeline for a specific use case that is not yet supported, you might have to copy the pipeline file and tweak the code to your needs. We try to make the pipeline code as readable as possible so that each part –from pre-processing to diffusing to post-processing– can easily be adapted. If you would like the community to benefit from your customized pipeline, we would love to see a contribution to our [community-examples](https://github.com/huggingface/diffusers/tree/main/examples/community). If you feel that an important pipeline should be part of the official pipelines but isn't, a contribution to the [official pipelines](./overview) would be even better.
|
||||
- **One-purpose-only**: Pipelines should be used for one task and one task only. Even if two tasks are very similar from a modeling point of view, *e.g.* image2image translation and in-painting, pipelines shall be used for one task only to keep them *easy-to-tweak* and *readable*.
|
||||
|
||||
## Examples
|
||||
|
||||
### Text-to-Image generation with Stable Diffusion
|
||||
|
||||
```python
|
||||
# make sure you're logged in with `huggingface-cli login`
|
||||
from diffusers import StableDiffusionPipeline, LMSDiscreteScheduler
|
||||
|
||||
pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5")
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "a photo of an astronaut riding a horse on mars"
|
||||
image = pipe(prompt).images[0]
|
||||
|
||||
image.save("astronaut_rides_horse.png")
|
||||
```
|
||||
|
||||
### Image-to-Image text-guided generation with Stable Diffusion
|
||||
|
||||
The `StableDiffusionImg2ImgPipeline` lets you pass a text prompt and an initial image to condition the generation of new images.
|
||||
|
||||
```python
|
||||
import requests
|
||||
from PIL import Image
|
||||
from io import BytesIO
|
||||
|
||||
from diffusers import StableDiffusionImg2ImgPipeline
|
||||
|
||||
# load the pipeline
|
||||
device = "cuda"
|
||||
pipe = StableDiffusionImg2ImgPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", revision="fp16", torch_dtype=torch.float16
|
||||
).to(device)
|
||||
|
||||
# let's download an initial image
|
||||
url = "https://raw.githubusercontent.com/CompVis/stable-diffusion/main/assets/stable-samples/img2img/sketch-mountains-input.jpg"
|
||||
|
||||
response = requests.get(url)
|
||||
init_image = Image.open(BytesIO(response.content)).convert("RGB")
|
||||
init_image = init_image.resize((768, 512))
|
||||
|
||||
prompt = "A fantasy landscape, trending on artstation"
|
||||
|
||||
images = pipe(prompt=prompt, image=init_image, strength=0.75, guidance_scale=7.5).images
|
||||
|
||||
images[0].save("fantasy_landscape.png")
|
||||
```
|
||||
You can also run this example on colab [](https://colab.research.google.com/github/huggingface/notebooks/blob/main/diffusers/image_2_image_using_diffusers.ipynb)
|
||||
|
||||
### Tweak prompts reusing seeds and latents
|
||||
|
||||
You can generate your own latents to reproduce results, or tweak your prompt on a specific result you liked. [This notebook](https://github.com/pcuenca/diffusers-examples/blob/main/notebooks/stable-diffusion-seeds.ipynb) shows how to do it step by step. You can also run it in Google Colab [](https://colab.research.google.com/github/pcuenca/diffusers-examples/blob/main/notebooks/stable-diffusion-seeds.ipynb).
|
||||
|
||||
|
||||
### In-painting using Stable Diffusion
|
||||
|
||||
The `StableDiffusionInpaintPipeline` lets you edit specific parts of an image by providing a mask and text prompt.
|
||||
|
||||
```python
|
||||
import PIL
|
||||
import requests
|
||||
import torch
|
||||
from io import BytesIO
|
||||
|
||||
from diffusers import StableDiffusionInpaintPipeline
|
||||
|
||||
|
||||
def download_image(url):
|
||||
response = requests.get(url)
|
||||
return PIL.Image.open(BytesIO(response.content)).convert("RGB")
|
||||
|
||||
|
||||
img_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo.png"
|
||||
mask_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo_mask.png"
|
||||
|
||||
init_image = download_image(img_url).resize((512, 512))
|
||||
mask_image = download_image(mask_url).resize((512, 512))
|
||||
|
||||
pipe = StableDiffusionInpaintPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-inpainting",
|
||||
revision="fp16",
|
||||
torch_dtype=torch.float16,
|
||||
)
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "Face of a yellow cat, high resolution, sitting on a park bench"
|
||||
image = pipe(prompt=prompt, image=init_image, mask_image=mask_image).images[0]
|

## Overview

[Paint by Example: Exemplar-based Image Editing with Diffusion Models](https://arxiv.org/abs/2211.13227) by Binxin Yang, Shuyang Gu, Bo Zhang, Ting Zhang, Xuejin Chen, Xiaoyan Sun, Dong Chen, Fang Wen
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*Language-guided image editing has achieved great success recently. In this paper, for the first time, we investigate exemplar-guided image editing for more precise control. We achieve this goal by leveraging self-supervised training to disentangle and re-organize the source image and the exemplar. However, the naive approach will cause obvious fusing artifacts. We carefully analyze it and propose an information bottleneck and strong augmentations to avoid the trivial solution of directly copying and pasting the exemplar image. Meanwhile, to ensure the controllability of the editing process, we design an arbitrary shape mask for the exemplar image and leverage the classifier-free guidance to increase the similarity to the exemplar image. The whole framework involves a single forward of the diffusion model without any iterative optimization. We demonstrate that our method achieves an impressive performance and enables controllable editing on in-the-wild images with high fidelity.*

# PNDM

||||
|
||||
## Overview
|
||||
|
||||
[Pseudo Numerical methods for Diffusion Models on manifolds](https://arxiv.org/abs/2202.09778) (PNDM) by Luping Liu, Yi Ren, Zhijie Lin and Zhou Zhao.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
Denoising Diffusion Probabilistic Models (DDPMs) can generate high-quality samples such as image and audio samples. However, DDPMs require hundreds to thousands of iterations to produce final samples. Several prior works have successfully accelerated DDPMs through adjusting the variance schedule (e.g., Improved Denoising Diffusion Probabilistic Models) or the denoising equation (e.g., Denoising Diffusion Implicit Models (DDIMs)). However, these acceleration methods cannot maintain the quality of samples and even introduce new noise at a high speedup rate, which limit their practicability. To accelerate the inference process while keeping the sample quality, we provide a fresh perspective that DDPMs should be treated as solving differential equations on manifolds. Under such a perspective, we propose pseudo numerical methods for diffusion models (PNDMs). Specifically, we figure out how to solve differential equations on manifolds and show that DDIMs are simple cases of pseudo numerical methods. We change several classical numerical methods to corresponding pseudo numerical methods and find that the pseudo linear multi-step method is the best in most situations. According to our experiments, by directly using pre-trained models on Cifar10, CelebA and LSUN, PNDMs can generate higher quality synthetic images with only 50 steps compared with 1000-step DDIMs (20x speedup), significantly outperform DDIMs with 250 steps (by around 0.4 in FID) and have good generalization on different variance schedules.

# RePaint
|
||||
|
||||
## Overview
|
||||
|
||||
[RePaint: Inpainting using Denoising Diffusion Probabilistic Models](https://arxiv.org/abs/2201.09865) (PNDM) by Andreas Lugmayr, Martin Danelljan, Andres Romero, Fisher Yu, Radu Timofte, Luc Van Gool.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
Free-form inpainting is the task of adding new content to an image in the regions specified by an arbitrary binary mask. Most existing approaches train for a certain distribution of masks, which limits their generalization capabilities to unseen mask types. Furthermore, training with pixel-wise and perceptual losses often leads to simple textural extensions towards the missing areas instead of semantically meaningful generation. In this work, we propose RePaint: A Denoising Diffusion Probabilistic Model (DDPM) based inpainting approach that is applicable to even extreme masks. We employ a pretrained unconditional DDPM as the generative prior. To condition the generation process, we only alter the reverse diffusion iterations by sampling the unmasked regions using the given image information. Since this technique does not modify or condition the original DDPM network itself, the model produces high-quality and diverse output images for any inpainting form. We validate our method for both faces and general-purpose image inpainting using standard and extreme masks.
|
||||
RePaint outperforms state-of-the-art Autoregressive, and GAN approaches for at least five out of six mask distributions.

|
||||
|
||||
[Score-Based Generative Modeling through Stochastic Differential Equations](https://arxiv.org/abs/2011.13456) (Score SDE) by Yang Song, Jascha Sohl-Dickstein, Diederik P. Kingma, Abhishek Kumar, Stefano Ermon and Ben Poole.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
Creating noise from data is easy; creating data from noise is generative modeling. We present a stochastic differential equation (SDE) that smoothly transforms a complex data distribution to a known prior distribution by slowly injecting noise, and a corresponding reverse-time SDE that transforms the prior distribution back into the data distribution by slowly removing the noise. Crucially, the reverse-time SDE depends only on the time-dependent gradient field (\aka, score) of the perturbed data distribution. By leveraging advances in score-based generative modeling, we can accurately estimate these scores with neural networks, and use numerical SDE solvers to generate samples. We show that this framework encapsulates previous approaches in score-based generative modeling and diffusion probabilistic modeling, allowing for new sampling procedures and new modeling capabilities. In particular, we introduce a predictor-corrector framework to correct errors in the evolution of the discretized reverse-time SDE. We also derive an equivalent neural ODE that samples from the same distribution as the SDE, but additionally enables exact likelihood computation, and improved sampling efficiency. In addition, we provide a new way to solve inverse problems with score-based models, as demonstrated with experiments on class-conditional generation, image inpainting, and colorization. Combined with multiple architectural improvements, we achieve record-breaking performance for unconditional image generation on CIFAR-10 with an Inception score of 9.89 and FID of 2.20, a competitive likelihood of 2.99 bits/dim, and demonstrate high fidelity generation of 1024 x 1024 images for the first time from a score-based generative model.

# Stable diffusion pipelines
|
||||
|
||||
Stable Diffusion is a text-to-image _latent diffusion_ model created by the researchers and engineers from [CompVis](https://github.com/CompVis), [Stability AI](https://stability.ai/) and [LAION](https://laion.ai/). It's trained on 512x512 images from a subset of the [LAION-5B](https://laion.ai/blog/laion-5b/) dataset. This model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and can run on consumer GPUs.
|
||||
|
||||
Latent diffusion is the research on top of which Stable Diffusion was built. It was proposed in [High-Resolution Image Synthesis with Latent Diffusion Models](https://arxiv.org/abs/2112.10752) by Robin Rombach, Andreas Blattmann, Dominik Lorenz, Patrick Esser, Björn Ommer. You can learn more details about it in the [specific pipeline for latent diffusion](pipelines/latent_diffusion) that is part of 🤗 Diffusers.
|
||||
|
||||
For more details about how Stable Diffusion works and how it differs from the base latent diffusion model, please refer to the official [launch announcement post](https://stability.ai/blog/stable-diffusion-announcement) and [this section of our own blog post](https://huggingface.co/blog/stable_diffusion#how-does-stable-diffusion-work).
|
||||
|
||||
*Tips*:
|
||||
- To tweak your prompts on a specific result you liked, you can generate your own latents, as demonstrated in the following notebook: [](https://colab.research.google.com/github/pcuenca/diffusers-examples/blob/main/notebooks/stable-diffusion-seeds.ipynb)

|
||||
## Tips
|
||||
|
||||
### How to load and use different schedulers.
|
||||
|
||||
The stable diffusion pipeline uses [`PNDMScheduler`] scheduler by default. But `diffusers` provides many other schedulers that can be used with the stable diffusion pipeline such as [`DDIMScheduler`], [`LMSDiscreteScheduler`], [`EulerDiscreteScheduler`], [`EulerAncestralDiscreteScheduler`] etc.
|
||||
To use a different scheduler, you can either change it via the [`ConfigMixin.from_config`] method or pass the `scheduler` argument to the `from_pretrained` method of the pipeline. For example, to use the [`EulerDiscreteScheduler`], you can do the following:
|
||||
|
||||
```python
|
||||
>>> from diffusers import StableDiffusionPipeline, EulerDiscreteScheduler
|
||||
|
||||
>>> pipeline = StableDiffusionPipeline.from_pretrained("CompVis/stable-diffusion-v1-4")
|
||||
>>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
|
||||
|
||||
>>> # or
|
||||
>>> euler_scheduler = EulerDiscreteScheduler.from_pretrained("CompVis/stable-diffusion-v1-4", subfolder="scheduler")
|
||||
>>> pipeline = StableDiffusionPipeline.from_pretrained("CompVis/stable-diffusion-v1-4", scheduler=euler_scheduler)
|
||||
```
|
||||
|
||||
|
||||
### How to convert all use cases with multiple or single pipeline
|
||||
|
||||
If you want to use all possible use cases in a single `DiffusionPipeline` you can either:
|
||||
- Make use of the [Stable Diffusion Mega Pipeline](https://github.com/huggingface/diffusers/tree/main/examples/community#stable-diffusion-mega) or
|
||||
- Make use of the `components` functionality to instantiate all components in the most memory-efficient way:
|
||||
|
||||
```python
|
||||
>>> from diffusers import (
|
||||
... StableDiffusionPipeline,
|
||||
... StableDiffusionImg2ImgPipeline,
|
||||
... StableDiffusionInpaintPipeline,
|
||||
... )
|
||||
|
||||
>>> text2img = StableDiffusionPipeline.from_pretrained("CompVis/stable-diffusion-v1-4")
|
||||
>>> img2img = StableDiffusionImg2ImgPipeline(**text2img.components)
|
||||
>>> inpaint = StableDiffusionInpaintPipeline(**text2img.components)
|
||||
|
||||
>>> # now you can use text2img(...), img2img(...), inpaint(...) just like the call methods of each respective pipeline
|
||||
```

Stable Diffusion 2 is a text-to-image _latent diffusion_ model built upon the work of the original [Stable Diffusion](https://stability.ai/blog/stable-diffusion-public-release), and it was led by Robin Rombach and Katherine Crowson from [Stability AI](https://stability.ai/) and [LAION](https://laion.ai/).
|
||||
Stable Diffusion 2 is a text-to-image _latent diffusion_ model built upon the work of [Stable Diffusion 1](https://stability.ai/blog/stable-diffusion-public-release).
|
||||
The project to train Stable Diffusion 2 was led by Robin Rombach and Katherine Crowson from [Stability AI](https://stability.ai/) and [LAION](https://laion.ai/).
|
||||
|
||||
*The Stable Diffusion 2.0 release includes robust text-to-image models trained using a brand new text encoder (OpenCLIP), developed by LAION with support from Stability AI, which greatly improves the quality of the generated images compared to earlier V1 releases. The text-to-image models in this release can generate images with default resolutions of both 512x512 pixels and 768x768 pixels.
|
||||
These models are trained on an aesthetic subset of the [LAION-5B dataset](https://laion.ai/blog/laion-5b/) created by the DeepFloyd team at Stability AI, which is then further filtered to remove adult content using [LAION’s NSFW filter](https://openreview.net/forum?id=M3Y74vmsMcY).*

|
||||
The architecture of Stable Diffusion 2 is more or less identical to the original [Stable Diffusion model](./text2img) so check out it's API documentation for how to use Stable Diffusion 2. We recommend using the [`DPMSolverMultistepScheduler`] as it's currently the fastest scheduler.

### How to load and use different schedulers.
|
||||
|
||||
The stable diffusion pipeline uses [`DDIMScheduler`] scheduler by default. But `diffusers` provides many other schedulers that can be used with the stable diffusion pipeline such as [`PNDMScheduler`], [`LMSDiscreteScheduler`], [`EulerDiscreteScheduler`], [`EulerAncestralDiscreteScheduler`] etc.
|
||||
To use a different scheduler, you can either change it via the [`ConfigMixin.from_config`] method or pass the `scheduler` argument to the `from_pretrained` method of the pipeline. For example, to use the [`EulerDiscreteScheduler`], you can do the following:
|
||||
|
||||
```python
|
||||
>>> from diffusers import StableDiffusionPipeline, EulerDiscreteScheduler
|
||||
|
||||
>>> pipeline = StableDiffusionPipeline.from_pretrained("stabilityai/stable-diffusion-2")
|
||||
>>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
|
||||
|
||||
>>> # or
|
||||
>>> euler_scheduler = EulerDiscreteScheduler.from_pretrained("stabilityai/stable-diffusion-2", subfolder="scheduler")
|
||||
>>> pipeline = StableDiffusionPipeline.from_pretrained("stabilityai/stable-diffusion-2", scheduler=euler_scheduler)
|
||||
```

# Safe Stable Diffusion
|
||||
|
||||
Safe Stable Diffusion was proposed in [Safe Latent Diffusion: Mitigating Inappropriate Degeneration in Diffusion Models](https://arxiv.org/abs/2211.05105) and mitigates the well known issue that models like Stable Diffusion that are trained on unfiltered, web-crawled datasets tend to suffer from inappropriate degeneration. For instance Stable Diffusion may unexpectedly generate nudity, violence, images depicting self-harm, or otherwise offensive content.
|
||||
Safe Stable Diffusion is an extension to the Stable Diffusion that drastically reduces content like this.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*Text-conditioned image generation models have recently achieved astonishing results in image quality and text alignment and are consequently employed in a fast-growing number of applications. Since they are highly data-driven, relying on billion-sized datasets randomly scraped from the internet, they also suffer, as we demonstrate, from degenerated and biased human behavior. In turn, they may even reinforce such biases. To help combat these undesired side effects, we present safe latent diffusion (SLD). Specifically, to measure the inappropriate degeneration due to unfiltered and imbalanced training sets, we establish a novel image generation test bed-inappropriate image prompts (I2P)-containing dedicated, real-world image-to-text prompts covering concepts such as nudity and violence. As our exhaustive empirical evaluation demonstrates, the introduced SLD removes and suppresses inappropriate image parts during the diffusion process, with no additional training required and no adverse effect on overall image quality or text alignment.*

|
||||
|
||||
## Tips
|
||||
|
||||
- Safe Stable Diffusion may also be used with weights of [Stable Diffusion](./api/pipelines/stable_diffusion).
|
||||
|
||||
### Run Safe Stable Diffusion
|
||||
|
||||
Safe Stable Diffusion can be tested very easily with the [`StableDiffusionPipelineSafe`], and the `"AIML-TUDA/stable-diffusion-safe"` checkpoint exactly in the same way it is shown in the [Conditional Image Generation Guide](./using-diffusers/conditional_image_generation).
|
||||
|
||||
### Interacting with the Safety Concept
|
||||
|
||||
To check and edit the currently used safety concept, use the `safety_concept` property of [`StableDiffusionPipelineSafe`]
|
||||
```python
|
||||
>>> from diffusers import StableDiffusionPipelineSafe
|
||||
|
||||
>>> pipeline = StableDiffusionPipelineSafe.from_pretrained("AIML-TUDA/stable-diffusion-safe")
|
||||
>>> pipeline.safety_concept
|
||||
```
|
||||
For each image generation the active concept is also contained in [`StableDiffusionSafePipelineOutput`].
|
||||
|
||||
### Using pre-defined safety configurations
|
||||
|
||||
You may use the 4 configurations defined in the [Safe Latent Diffusion paper](https://arxiv.org/abs/2211.05105) as follows:
|
||||
|
||||
```python
|
||||
>>> from diffusers import StableDiffusionPipelineSafe
|
||||
>>> from diffusers.pipelines.stable_diffusion_safe import SafetyConfig
|
||||
|
||||
>>> pipeline = StableDiffusionPipelineSafe.from_pretrained("AIML-TUDA/stable-diffusion-safe")
|
||||
>>> prompt = "the four horsewomen of the apocalypse, painting by tom of finland, gaston bussiere, craig mullins, j. c. leyendecker"
|
||||
>>> out = pipeline(prompt=prompt, **SafetyConfig.MAX)
|
||||
```
|
||||
|
||||
The following configurations are available: `SafetyConfig.WEAK`, `SafetyConfig.MEDIUM`, `SafetyConfig.STRONg`, and `SafetyConfig.MAX`.
|
||||
|
||||
### How to load and use different schedulers.
|
||||
|
||||
The safe stable diffusion pipeline uses [`PNDMScheduler`] scheduler by default. But `diffusers` provides many other schedulers that can be used with the stable diffusion pipeline such as [`DDIMScheduler`], [`LMSDiscreteScheduler`], [`EulerDiscreteScheduler`], [`EulerAncestralDiscreteScheduler`] etc.
|
||||
To use a different scheduler, you can either change it via the [`ConfigMixin.from_config`] method or pass the `scheduler` argument to the `from_pretrained` method of the pipeline. For example, to use the [`EulerDiscreteScheduler`], you can do the following:
|
||||
|
||||
```python
|
||||
>>> from diffusers import StableDiffusionPipelineSafe, EulerDiscreteScheduler
|
||||
|
||||
>>> pipeline = StableDiffusionPipelineSafe.from_pretrained("AIML-TUDA/stable-diffusion-safe")
|
||||
>>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
|
||||
|
||||
>>> # or
|
||||
>>> euler_scheduler = EulerDiscreteScheduler.from_pretrained("AIML-TUDA/stable-diffusion-safe", subfolder="scheduler")
|
||||
>>> pipeline = StableDiffusionPipelineSafe.from_pretrained(
|
||||
... "AIML-TUDA/stable-diffusion-safe", scheduler=euler_scheduler
|
||||
... )
|
||||
```

# Stochastic Karras VE

## Overview
|
||||
|
||||
[Elucidating the Design Space of Diffusion-Based Generative Models](https://arxiv.org/abs/2206.00364) by Tero Karras, Miika Aittala, Timo Aila and Samuli Laine.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
We argue that the theory and practice of diffusion-based generative models are currently unnecessarily convoluted and seek to remedy the situation by presenting a design space that clearly separates the concrete design choices. This lets us identify several changes to both the sampling and training processes, as well as preconditioning of the score networks. Together, our improvements yield new state-of-the-art FID of 1.79 for CIFAR-10 in a class-conditional setting and 1.97 in an unconditional setting, with much faster sampling (35 network evaluations per image) than prior designs. To further demonstrate their modular nature, we show that our design changes dramatically improve both the efficiency and quality obtainable with pre-trained score networks from previous work, including improving the FID of an existing ImageNet-64 model from 2.07 to near-SOTA 1.55.
|
||||
|
||||
This pipeline implements the Stochastic sampling tailored to the Variance-Expanding (VE) models.

# VersatileDiffusion
|
||||
|
||||
VersatileDiffusion was proposed in [Versatile Diffusion: Text, Images and Variations All in One Diffusion Model](https://arxiv.org/abs/2211.08332) by Xingqian Xu, Zhangyang Wang, Eric Zhang, Kai Wang, Humphrey Shi .
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*The recent advances in diffusion models have set an impressive milestone in many generation tasks. Trending works such as DALL-E2, Imagen, and Stable Diffusion have attracted great interest in academia and industry. Despite the rapid landscape changes, recent new approaches focus on extensions and performance rather than capacity, thus requiring separate models for separate tasks. In this work, we expand the existing single-flow diffusion pipeline into a multi-flow network, dubbed Versatile Diffusion (VD), that handles text-to-image, image-to-text, image-variation, and text-variation in one unified model. Moreover, we generalize VD to a unified multi-flow multimodal diffusion framework with grouped layers, swappable streams, and other propositions that can process modalities beyond images and text. Through our experiments, we demonstrate that VD and its underlying framework have the following merits: a) VD handles all subtasks with competitive quality; b) VD initiates novel extensions and applications such as disentanglement of style and semantic, image-text dual-guided generation, etc.; c) Through these experiments and applications, VD provides more semantic insights of the generated outputs.*
|
||||
|
||||
## Tips
|
||||
|
||||
- VersatileDiffusion is conceptually very similar as [Stable Diffusion](./api/pipelines/stable_diffusion), but instead of providing just a image data stream conditioned on text, VersatileDiffusion provides both a image and text data stream and can be conditioned on both text and image.
|
||||
|
||||
### *Run VersatileDiffusion*
|
||||
|
||||
You can both load the memory intensive "all-in-one" [`VersatileDiffusionPipeline`] that can run all tasks
|
||||
with the same class as shown in [`VersatileDiffusionPipeline.text_to_image`], [`VersatileDiffusionPipeline.image_variation`], and [`VersatileDiffusionPipeline.dual_guided`]
|
||||
|
||||
**or**
|
||||
|
||||
You can run the individual pipelines which are much more memory efficient:
|
||||
|
||||
- *Text-to-Image*: [`VersatileDiffusionTextToImagePipeline.__call__`]
|
||||
- *Image Variation*: [`VersatileDiffusionImageVariationPipeline.__call__`]
|
||||
- *Dual Text and Image Guided Generation*: [`VersatileDiffusionDualGuidedPipeline.__call__`]
|
||||
|
||||
### *How to load and use different schedulers.*
|
||||
|
||||
The versatile diffusion pipelines uses [`DDIMScheduler`] scheduler by default. But `diffusers` provides many other schedulers that can be used with the alt diffusion pipeline such as [`PNDMScheduler`], [`LMSDiscreteScheduler`], [`EulerDiscreteScheduler`], [`EulerAncestralDiscreteScheduler`] etc.
|
||||
To use a different scheduler, you can either change it via the [`ConfigMixin.from_config`] method or pass the `scheduler` argument to the `from_pretrained` method of the pipeline. For example, to use the [`EulerDiscreteScheduler`], you can do the following:
|
||||
|
||||
```python
|
||||
>>> from diffusers import VersatileDiffusionPipeline, EulerDiscreteScheduler
|
||||
|
||||
>>> pipeline = VersatileDiffusionPipeline.from_pretrained("shi-labs/versatile-diffusion")
|
||||
>>> pipeline.scheduler = EulerDiscreteScheduler.from_config(pipeline.scheduler.config)
|
||||
|
||||
>>> # or
|
||||
>>> euler_scheduler = EulerDiscreteScheduler.from_pretrained("shi-labs/versatile-diffusion", subfolder="scheduler")
|
||||
>>> pipeline = VersatileDiffusionPipeline.from_pretrained("shi-labs/versatile-diffusion", scheduler=euler_scheduler)
|
||||

# VQDiffusion

[Vector Quantized Diffusion Model for Text-to-Image Synthesis](https://arxiv.org/abs/2111.14822) by Shuyang Gu, Dong Chen, Jianmin Bao, Fang Wen, Bo Zhang, Dongdong Chen, Lu Yuan, Baining Guo
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
We present the vector quantized diffusion (VQ-Diffusion) model for text-to-image generation. This method is based on a vector quantized variational autoencoder (VQ-VAE) whose latent space is modeled by a conditional variant of the recently developed Denoising Diffusion Probabilistic Model (DDPM). We find that this latent-space method is well-suited for text-to-image generation tasks because it not only eliminates the unidirectional bias with existing methods but also allows us to incorporate a mask-and-replace diffusion strategy to avoid the accumulation of errors, which is a serious problem with existing methods. Our experiments show that the VQ-Diffusion produces significantly better text-to-image generation results when compared with conventional autoregressive (AR) models with similar numbers of parameters. Compared with previous GAN-based text-to-image methods, our VQ-Diffusion can handle more complex scenes and improve the synthesized image quality by a large margin. Finally, we show that the image generation computation in our method can be made highly efficient by reparameterization. With traditional AR methods, the text-to-image generation time increases linearly with the output image resolution and hence is quite time consuming even for normal size images. The VQ-Diffusion allows us to achieve a better trade-off between quality and speed. Our experiments indicate that the VQ-Diffusion model with the reparameterization is fifteen times faster than traditional AR methods while achieving a better image quality.

# Schedulers
|
||||
|
||||
Diffusers contains multiple pre-built schedule functions for the diffusion process.
|
||||
|
||||
## What is a scheduler?
|
||||
|
||||
The schedule functions, denoted *Schedulers* in the library take in the output of a trained model, a sample which the diffusion process is iterating on, and a timestep to return a denoised sample. That's why schedulers may also be called *Samplers* in other diffusion models implementations.
|
||||
|
||||
- Schedulers define the methodology for iteratively adding noise to an image or for updating a sample based on model outputs.
|
||||
- adding noise in different manners represent the algorithmic processes to train a diffusion model by adding noise to images.
|
||||
- for inference, the scheduler defines how to update a sample based on an output from a pretrained model.
|
||||
- Schedulers are often defined by a *noise schedule* and an *update rule* to solve the differential equation solution.
|
||||
|
||||
### Discrete versus continuous schedulers
|
||||
|
||||
All schedulers take in a timestep to predict the updated version of the sample being diffused.
|
||||
The timesteps dictate where in the diffusion process the step is, where data is generated by iterating forward in time and inference is executed by propagating backwards through timesteps.
|
||||
Different algorithms use timesteps that both discrete (accepting `int` inputs), such as the [`DDPMScheduler`] or [`PNDMScheduler`], and continuous (accepting `float` inputs), such as the score-based schedulers [`ScoreSdeVeScheduler`] or [`ScoreSdeVpScheduler`].
|
||||
|
||||
## Designing Re-usable schedulers
|
||||
|
||||
The core design principle between the schedule functions is to be model, system, and framework independent.
|
||||
This allows for rapid experimentation and cleaner abstractions in the code, where the model prediction is separated from the sample update.
|
||||
To this end, the design of schedulers is such that:
|
||||
|
||||
- Schedulers can be used interchangeably between diffusion models in inference to find the preferred trade-off between speed and generation quality.
|
||||
- Schedulers are currently by default in PyTorch, but are designed to be framework independent (partial Jax support currently exists).
|
||||
|
||||
|
||||
## API
|
||||
|
||||
The core API for any new scheduler must follow a limited structure.
|
||||
- Schedulers should provide one or more `def step(...)` functions that should be called to update the generated sample iteratively.
|
||||
- Schedulers should provide a `set_timesteps(...)` method that configures the parameters of a schedule function for a specific inference task.
|
||||
- Schedulers should be framework-specific.
|
||||
|
||||
The base class [`SchedulerMixin`] implements low level utilities used by multiple schedulers.
|
||||
|
||||
### SchedulerMixin

# How to contribute to Diffusers 🧨
|
||||
|
||||
We ❤️ contributions from the open-source community! Everyone is welcome, and all types of participation –not just code– are valued and appreciated. Answering questions, helping others, reaching out and improving the documentation are all immensely valuable to the community, so don't be afraid and get involved if you're up for it!
|
||||
|
||||
It also helps us if you spread the word: reference the library from blog posts
|
||||
on the awesome projects it made possible, shout out on Twitter every time it has
|
||||
helped you, or simply star the repo to say "thank you".
|
||||
|
||||
We encourage everyone to start by saying 👋 in our public Discord channel. We discuss the hottest trends about diffusion models, ask questions, show-off personal projects, help each other with contributions, or just hang out ☕. <a href="https://discord.gg/G7tWnz98XR"><img alt="Join us on Discord" src="https://img.shields.io/discord/823813159592001537?color=5865F2&logo=discord&logoColor=white"></a>
|
||||
|
||||
Whichever way you choose to contribute, we strive to be part of an open, welcoming and kind community. Please, read our [code of conduct](https://github.com/huggingface/diffusers/blob/main/CODE_OF_CONDUCT.md) and be mindful to respect it during your interactions.
|
||||
|
||||
|
||||
## Overview
|
||||
|
||||
You can contribute in so many ways! Just to name a few:
|
||||
|
||||
* Fixing outstanding issues with the existing code.
|
||||
* Implementing [new diffusion pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines#contribution), [new schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers) or [new models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models).
|
||||
* [Contributing to the examples](https://github.com/huggingface/diffusers/tree/main/examples).
|
||||
* [Contributing to the documentation](https://github.com/huggingface/diffusers/tree/main/docs/source).
|
||||
* Submitting issues related to bugs or desired new features.
|
||||
|
||||
*All are equally valuable to the community.*
|
||||
|
||||
### Browse GitHub issues for suggestions
|
||||
|
||||
If you need inspiration, you can look out for [issues](https://github.com/huggingface/diffusers/issues) you'd like to tackle to contribute to the library. There are a few filters that can be helpful:
|
||||
|
||||
- See [Good first issues](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22) for general opportunities to contribute and getting started with the codebase.
|
||||
- See [New pipeline/model](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+pipeline%2Fmodel%22) to contribute exciting new diffusion models or diffusion pipelines.
|
||||
- See [New scheduler](https://github.com/huggingface/diffusers/issues?q=is%3Aopen+is%3Aissue+label%3A%22New+scheduler%22) to work on new samplers and schedulers.
|
||||
|
||||
|
||||
## Submitting a new issue or feature request
|
||||
|
||||
Do your best to follow these guidelines when submitting an issue or a feature
|
||||
request. It will make it easier for us to come back to you quickly and with good
|
||||
feedback.
|
||||
|
||||
### Did you find a bug?
|
||||
|
||||
The 🧨 Diffusers library is robust and reliable thanks to the users who notify us of
|
||||
the problems they encounter. So thank you for reporting an issue.
|
||||
|
||||
First, we would really appreciate it if you could **make sure the bug was not
|
||||
already reported** (use the search bar on GitHub under Issues).
|
||||
|
||||
### Do you want to implement a new diffusion pipeline / diffusion model?
|
||||
|
||||
Awesome! Please provide the following information:
|
||||
|
||||
* Short description of the diffusion pipeline and link to the paper;
|
||||
* Link to the implementation if it is open-source;
|
||||
* Link to the model weights if they are available.
|
||||
|
||||
If you are willing to contribute the model yourself, let us know so we can best
|
||||
guide you.
|
||||
|
||||
### Do you want a new feature (that is not a model)?
|
||||
|
||||
A world-class feature request addresses the following points:
|
||||
|
||||
1. Motivation first:
|
||||
* Is it related to a problem/frustration with the library? If so, please explain
|
||||
why. Providing a code snippet that demonstrates the problem is best.
|
||||
* Is it related to something you would need for a project? We'd love to hear
|
||||
about it!
|
||||
* Is it something you worked on and think could benefit the community?
|
||||
Awesome! Tell us what problem it solved for you.
|
||||
2. Write a *full paragraph* describing the feature;
|
||||
3. Provide a **code snippet** that demonstrates its future use;
|
||||
4. In case this is related to a paper, please attach a link;
|
||||
5. Attach any additional information (drawings, screenshots, etc.) you think may help.
|
||||
|
||||
If your issue is well written we're already 80% of the way there by the time you
|
||||
post it.
|
||||
|
||||
## Start contributing! (Pull Requests)
|
||||
|
||||
Before writing code, we strongly advise you to search through the existing PRs or
|
||||
issues to make sure that nobody is already working on the same thing. If you are
|
||||
unsure, it is always a good idea to open an issue to get some feedback.
|
||||
|
||||
You will need basic `git` proficiency to be able to contribute to
|
||||
🧨 Diffusers. `git` is not the easiest tool to use but it has the greatest
|
||||
manual. Type `git --help` in a shell and enjoy. If you prefer books, [Pro
|
||||
Git](https://git-scm.com/book/en/v2) is a very good reference.
|
||||
|
||||
Follow these steps to start contributing ([supported Python versions](https://github.com/huggingface/diffusers/blob/main/setup.py#L212)):
|
||||
|
||||
1. Fork the [repository](https://github.com/huggingface/diffusers) by
|
||||
clicking on the 'Fork' button on the repository's page. This creates a copy of the code
|
||||
under your GitHub user account.
|
||||
|
||||
2. Clone your fork to your local disk, and add the base repository as a remote:
|
||||
|
||||
```bash
|
||||
$ git clone git@github.com:<your Github handle>/diffusers.git
|
||||
$ cd diffusers
|
||||
$ git remote add upstream https://github.com/huggingface/diffusers.git
|
||||
```
|
||||
|
||||
3. Create a new branch to hold your development changes:
|
||||
|
||||
```bash
|
||||
$ git checkout -b a-descriptive-name-for-my-changes
|
||||
```
|
||||
|
||||
**Do not** work on the `main` branch.
|
||||
|
||||
4. Set up a development environment by running the following command in a virtual environment:
|
||||
|
||||
```bash
|
||||
$ pip install -e ".[dev]"
|
||||
```
|
||||
|
||||
(If Diffusers was already installed in the virtual environment, remove
|
||||
it with `pip uninstall diffusers` before reinstalling it in editable
|
||||
mode with the `-e` flag.)
|
||||
|
||||
To run the full test suite, you might need the additional dependency on `transformers` and `datasets` which requires a separate source
|
||||
install:
|
||||
|
||||
```bash
|
||||
$ git clone https://github.com/huggingface/transformers
|
||||
$ cd transformers
|
||||
$ pip install -e .
|
||||
```
|
||||
|
||||
```bash
|
||||
$ git clone https://github.com/huggingface/datasets
|
||||
$ cd datasets
|
||||
$ pip install -e .
|
||||
```
|
||||
|
||||
If you have already cloned that repo, you might need to `git pull` to get the most recent changes in the `datasets`
|
||||
library.
|
||||
|
||||
5. Develop the features on your branch.
|
||||
|
||||
As you work on the features, you should make sure that the test suite
|
||||
passes. You should run the tests impacted by your changes like this:
|
||||
|
||||
```bash
|
||||
$ pytest tests/<TEST_TO_RUN>.py
|
||||
```
|
||||
|
||||
You can also run the full suite with the following command, but it takes
|
||||
a beefy machine to produce a result in a decent amount of time now that
|
||||
Diffusers has grown a lot. Here is the command for it:
|
||||
|
||||
```bash
|
||||
$ make test
|
||||
```
|
||||
|
||||
For more information about tests, check out the
|
||||
[dedicated documentation](https://huggingface.co/docs/diffusers/testing)
|
||||
|
||||
🧨 Diffusers relies on `black` and `isort` to format its source code
|
||||
consistently. After you make changes, apply automatic style corrections and code verifications
|
||||
that can't be automated in one go with:
|
||||
|
||||
```bash
|
||||
$ make style
|
||||
```
|
||||
|
||||
🧨 Diffusers also uses `flake8` and a few custom scripts to check for coding mistakes. Quality
|
||||
control runs in CI, however you can also run the same checks with:
|
||||
|
||||
```bash
|
||||
$ make quality
|
||||
```
|
||||
|
||||
Once you're happy with your changes, add changed files using `git add` and
|
||||
make a commit with `git commit` to record your changes locally:
|
||||
|
||||
```bash
|
||||
$ git add modified_file.py
|
||||
$ git commit
|
||||
```
|
||||
|
||||
It is a good idea to sync your copy of the code with the original
|
||||
repository regularly. This way you can quickly account for changes:
|
||||
|
||||
```bash
|
||||
$ git fetch upstream
|
||||
$ git rebase upstream/main
|
||||
```
|
||||
|
||||
Push the changes to your account using:
|
||||
|
||||
```bash
|
||||
$ git push -u origin a-descriptive-name-for-my-changes
|
||||
```
|
||||
|
||||
6. Once you are satisfied (**and the checklist below is happy too**), go to the
|
||||
webpage of your fork on GitHub. Click on 'Pull request' to send your changes
|
||||
to the project maintainers for review.
|
||||
|
||||
7. It's ok if maintainers ask you for changes. It happens to core contributors
|
||||
too! So everyone can see the changes in the Pull request, work in your local
|
||||
branch and push the changes to your fork. They will automatically appear in
|
||||
the pull request.
|
||||
|
||||
|
||||
### Checklist
|
||||
|
||||
1. The title of your pull request should be a summary of its contribution;
|
||||
2. If your pull request addresses an issue, please mention the issue number in
|
||||
the pull request description to make sure they are linked (and people
|
||||
consulting the issue know you are working on it);
|
||||
3. To indicate a work in progress please prefix the title with `[WIP]`. These
|
||||
are useful to avoid duplicated work, and to differentiate it from PRs ready
|
||||
to be merged;
|
||||
4. Make sure existing tests pass;
|
||||
5. Add high-coverage tests. No quality testing = no merge.
|
||||
- If you are adding new `@slow` tests, make sure they pass using
|
||||
`RUN_SLOW=1 python -m pytest tests/test_my_new_model.py`.
|
||||
- If you are adding a new tokenizer, write tests, and make sure
|
||||
`RUN_SLOW=1 python -m pytest tests/test_tokenization_{your_model_name}.py` passes.
|
||||
CircleCI does not run the slow tests, but GitHub actions does every night!
|
||||
6. All public methods must have informative docstrings that work nicely with sphinx. See `[pipeline_latent_diffusion.py](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/latent_diffusion/pipeline_latent_diffusion.py)` for an example.
|
||||
7. Due to the rapidly growing repository, it is important to make sure that no files that would significantly weigh down the repository are added. This includes images, videos and other non-text files. We prefer to leverage a hf.co hosted `dataset` like
|
||||
the ones hosted on [`hf-internal-testing`](https://huggingface.co/hf-internal-testing) in which to place these files and reference or [huggingface/documentation-images](https://huggingface.co/datasets/huggingface/documentation-images).
|
||||
If an external contribution, feel free to add the images to your PR and ask a Hugging Face member to migrate your images
|
||||
to this dataset.
|
||||
|
||||
### Tests
|
||||
|
||||
An extensive test suite is included to test the library behavior and several examples. Library tests can be found in
|
||||
the [tests folder](https://github.com/huggingface/diffusers/tree/main/tests).
|
||||
|
||||
We like `pytest` and `pytest-xdist` because it's faster. From the root of the
|
||||
repository, here's how to run tests with `pytest` for the library:
|
||||
|
||||
```bash
|
||||
$ python -m pytest -n auto --dist=loadfile -s -v ./tests/
|
||||
```
|
||||
|
||||
In fact, that's how `make test` is implemented!
|
||||
|
||||
You can specify a smaller set of tests in order to test only the feature
|
||||
you're working on.
|
||||
|
||||
By default, slow tests are skipped. Set the `RUN_SLOW` environment variable to
|
||||
`yes` to run them. This will download many gigabytes of models — make sure you
|
||||
have enough disk space and a good Internet connection, or a lot of patience!
|
||||
|
||||
```bash
|
||||
$ RUN_SLOW=yes python -m pytest -n auto --dist=loadfile -s -v ./tests/
|
||||
```
|
||||
|
||||
`unittest` is fully supported, here's how to run tests with it:
|
||||
|
||||
```bash
|
||||
$ python -m unittest discover -s tests -t . -v
|
||||
$ python -m unittest discover -s examples -t examples -v
|
||||
```
|
||||
|
||||
### Syncing forked main with upstream (HuggingFace) main
|
||||
|
||||
To avoid pinging the upstream repository which adds reference notes to each upstream PR and sends unnecessary notifications to the developers involved in these PRs,
|
||||
when syncing the main branch of a forked repository, please, follow these steps:
|
||||
1. When possible, avoid syncing with the upstream using a branch and PR on the forked repository. Instead, merge directly into the forked main.
|
||||
2. If a PR is absolutely necessary, use the following steps after checking out your branch:
|
||||
```
|
||||
$ git checkout -b your-branch-for-syncing
|
||||
$ git pull --squash --no-commit upstream main
|
||||
$ git commit -m '<your message without GitHub references>'
|
||||
$ git push --set-upstream origin your-branch-for-syncing
|
||||
```
|
||||
|
||||
### Style guide
|
||||
|
||||
For documentation strings, 🧨 Diffusers follows the [google style](https://google.github.io/styleguide/pyguide.html).
|
||||
|
||||
|
||||
**This guide was heavily inspired by the awesome [scikit-learn guide to contributing](https://github.com/scikit-learn/scikit-learn/blob/main/CONTRIBUTING.md).**

# Philosophy
|
||||
|
||||
- Readability and clarity are preferred over highly optimized code. A strong importance is put on providing readable, intuitive and elementary code design. *E.g.*, the provided [schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers) are separated from the provided [models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models) and use well-commented code that can be read alongside the original paper.
|
||||
- Diffusers is **modality independent** and focuses on providing pretrained models and tools to build systems that generate **continuous outputs**, *e.g.* vision and audio. This is one of the guiding goals even if the initial pipelines are devoted to vision tasks.
|
||||
- Diffusion models and schedulers are provided as concise, elementary building blocks. In contrast, diffusion pipelines are a collection of end-to-end diffusion systems that can be used out-of-the-box, should stay as close as possible to their original implementations and can include components of other libraries, such as text encoders. Examples of diffusion pipelines are [Glide](https://github.com/openai/glide-text2im), [Latent Diffusion](https://github.com/CompVis/latent-diffusion) and [Stable Diffusion](https://github.com/compvis/stable-diffusion).

# Pipelines
|
||||
|
||||
The [`DiffusionPipeline`] is the quickest way to load any pretrained diffusion pipeline from the [Hub](https://huggingface.co/models?library=diffusers) for inference.
|
||||
|
||||
<Tip>
|
||||
|
||||
You shouldn't use the [`DiffusionPipeline`] class for training or finetuning a diffusion model. Individual
|
||||
components (for example, [`UNet2DModel`] and [`UNet2DConditionModel`]) of diffusion pipelines are usually trained individually, so we suggest directly working with them instead.
|
||||
|
||||
</Tip>
|
||||
|
||||
The pipeline type (for example [`StableDiffusionPipeline`]) of any diffusion pipeline loaded with [`~DiffusionPipeline.from_pretrained`] is automatically
|
||||
detected and pipeline components are loaded and passed to the `__init__` function of the pipeline.
|
||||
|
||||
Any pipeline object can be saved locally with [`~DiffusionPipeline.save_pretrained`].

# VAE Image Processor
|
||||
|
||||
The [`VaeImageProcessor`] provides a unified API for [`StableDiffusionPipeline`]'s to prepare image inputs for VAE encoding and post-processing outputs once they're decoded. This includes transformations such as resizing, normalization, and conversion between PIL Image, PyTorch, and NumPy arrays.
|
||||
|
||||
All pipelines with [`VaeImageProcessor`] accepts PIL Image, PyTorch tensor, or NumPy arrays as image inputs and returns outputs based on the `output_type` argument by the user. You can pass encoded image latents directly to the pipeline and return latents from the pipeline as a specific output with the `output_type` argument (for example `output_type="pt"`). This allows you to take the generated latents from one pipeline and pass it to another pipeline as input without leaving the latent space. It also makes it much easier to use multiple pipelines together by passing PyTorch tensors directly between different pipelines.

# Loaders
|
||||
|
||||
Adapters (textual inversion, LoRA, hypernetworks) allow you to modify a diffusion model to generate images in a specific style without training or finetuning the entire model. The adapter weights are typically only a tiny fraction of the pretrained model's which making them very portable. 🤗 Diffusers provides an easy-to-use `LoaderMixin` API to load adapter weights.
|
||||
|
||||
<Tip warning={true}>
|
||||

🧪 The `LoaderMixins` are highly experimental and prone to future changes. To use private or [gated](https://huggingface.co/docs/hub/models-gated#gated-models) models, log-in with `huggingface-cli login`.

# AsymmetricAutoencoderKL

Improved larger variational autoencoder (VAE) model with KL loss for inpainting task: [Designing a Better Asymmetric VQGAN for StableDiffusion](https://arxiv.org/abs/2306.04632) by Zixin Zhu, Xuelu Feng, Dongdong Chen, Jianmin Bao, Le Wang, Yinpeng Chen, Lu Yuan, Gang Hua.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*StableDiffusion is a revolutionary text-to-image generator that is causing a stir in the world of image generation and editing. Unlike traditional methods that learn a diffusion model in pixel space, StableDiffusion learns a diffusion model in the latent space via a VQGAN, ensuring both efficiency and quality. It not only supports image generation tasks, but also enables image editing for real images, such as image inpainting and local editing. However, we have observed that the vanilla VQGAN used in StableDiffusion leads to significant information loss, causing distortion artifacts even in non-edited image regions. To this end, we propose a new asymmetric VQGAN with two simple designs. Firstly, in addition to the input from the encoder, the decoder contains a conditional branch that incorporates information from task-specific priors, such as the unmasked image region in inpainting. Secondly, the decoder is much heavier than the encoder, allowing for more detailed recovery while only slightly increasing the total inference cost. The training cost of our asymmetric VQGAN is cheap, and we only need to retrain a new asymmetric decoder while keeping the vanilla VQGAN encoder and StableDiffusion unchanged. Our asymmetric VQGAN can be widely used in StableDiffusion-based inpainting and local editing methods. Extensive experiments demonstrate that it can significantly improve the inpainting and editing performance, while maintaining the original text-to-image capability. The code is available at https://github.com/buxiangzhiren/Asymmetric_VQGAN*

# AutoencoderKL
|
||||
|
||||
The variational autoencoder (VAE) model with KL loss was introduced in [Auto-Encoding Variational Bayes](https://arxiv.org/abs/1312.6114v11) by Diederik P. Kingma and Max Welling. The model is used in 🤗 Diffusers to encode images into latents and to decode latent representations into images.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*How can we perform efficient inference and learning in directed probabilistic models, in the presence of continuous latent variables with intractable posterior distributions, and large datasets? We introduce a stochastic variational inference and learning algorithm that scales to large datasets and, under some mild differentiability conditions, even works in the intractable case. Our contributions are two-fold. First, we show that a reparameterization of the variational lower bound yields a lower bound estimator that can be straightforwardly optimized using standard stochastic gradient methods. Second, we show that for i.i.d. datasets with continuous latent variables per datapoint, posterior inference can be made especially efficient by fitting an approximate inference model (also called a recognition model) to the intractable posterior using the proposed lower bound estimator. Theoretical advantages are reflected in experimental results.*

# ControlNet
|
||||
|
||||
The ControlNet model was introduced in [Adding Conditional Control to Text-to-Image Diffusion Models](https://huggingface.co/papers/2302.05543) by Lvmin Zhang and Maneesh Agrawala. It provides a greater degree of control over text-to-image generation by conditioning the model on additional inputs such as edge maps, depth maps, segmentation maps, and keypoints for pose detection.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*We present a neural network structure, ControlNet, to control pretrained large diffusion models to support additional input conditions. The ControlNet learns task-specific conditions in an end-to-end way, and the learning is robust even when the training dataset is small (< 50k). Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal devices. Alternatively, if powerful computation clusters are available, the model can scale to large amounts (millions to billions) of data. We report that large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc. This may enrich the methods to control large diffusion models and further facilitate related applications.*

# Models
|
||||
|

🤗 Diffusers provides pretrained models for popular algorithms and modules to create custom diffusion systems. The primary function of models is to denoise an input sample as modeled by the distribution \\(p_{\theta}(x_{t-1}|x_{t})\\).
|
||||
|
||||
All models are built from the base [`ModelMixin`] class which is a [`torch.nn.module`](https://pytorch.org/docs/stable/generated/torch.nn.Module.html) providing basic functionality for saving and loading models, locally and from the Hugging Face Hub.

# Prior Transformer
|
||||
|
||||
The Prior Transformer was originally introduced in [Hierarchical Text-Conditional Image Generation with CLIP Latents
|
||||
](https://huggingface.co/papers/2204.06125) by Ramesh et al. It is used to predict CLIP image embeddings from CLIP text embeddings; image embeddings are predicted through a denoising diffusion process.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Contrastive models like CLIP have been shown to learn robust representations of images that capture both semantics and style. To leverage these representations for image generation, we propose a two-stage model: a prior that generates a CLIP image embedding given a text caption, and a decoder that generates an image conditioned on the image embedding. We show that explicitly generating image representations improves image diversity with minimal loss in photorealism and caption similarity. Our decoders conditioned on image representations can also produce variations of an image that preserve both its semantics and style, while varying the non-essential details absent from the image representation. Moreover, the joint embedding space of CLIP enables language-guided image manipulations in a zero-shot fashion. We use diffusion models for the decoder and experiment with both autoregressive and diffusion models for the prior, finding that the latter are computationally more efficient and produce higher-quality samples.*

# Transformer2D
|
||||
|
||||
A Transformer model for image-like data from [CompVis](https://huggingface.co/CompVis) that is based on the [Vision Transformer](https://huggingface.co/papers/2010.11929) introduced by Dosovitskiy et al. The [`Transformer2DModel`] accepts discrete (classes of vector embeddings) or continuous (actual embeddings) inputs.
|
||||
|
||||
When the input is **continuous**:
|
||||
|
||||
1. Project the input and reshape it to `(batch_size, sequence_length, feature_dimension)`.
|
||||
2. Apply the Transformer blocks in the standard way.
|
||||
3. Reshape to image.
|
||||
|
||||
When the input is **discrete**:
|
||||
|
||||
<Tip>
|
||||
|
||||
It is assumed one of the input classes is the masked latent pixel. The predicted classes of the unnoised image don't contain a prediction for the masked pixel because the unnoised image cannot be masked.
|
||||
|
||||
</Tip>
|
||||
|
||||
1. Convert input (classes of latent pixels) to embeddings and apply positional embeddings.
|
||||
2. Apply the Transformer blocks in the standard way.

||||
3. Predict classes of unnoised image.

# UNet1DModel

It is one of the most important components of a diffusion system because it facilitates the actual diffusion process. There are several variants of the UNet model in 🤗 Diffusers, depending on it's number of dimensions and whether it is a conditional model or not. This is a 1D UNet model.

In this paper, we present a network and training strategy that relies on the strong use of data augmentation to use the available annotated samples more efficiently. The architecture consists of a contracting path to capture context and a symmetric expanding path that enables precise localization. We show that such a network can be trained end-to-end from very few images and outperforms the prior best method (a sliding-window convolutional network) on the ISBI challenge for segmentation of neuronal structures in electron microscopic stacks. Using the same network trained on transmitted light microscopy images (phase contrast and DIC) we won the ISBI cell tracking challenge 2015 in these categories by a large margin. Moreover, the network is fast. Segmentation of a 512x512 image takes less than a second on a recent GPU.

# VQModel
|
||||
|
||||
The VQ-VAE model was introduced in [Neural Discrete Representation Learning](https://huggingface.co/papers/1711.00937) by Aaron van den Oord, Oriol Vinyals and Koray Kavukcuoglu. The model is used in 🤗 Diffusers to decode latent representations into images. Unlike [`AutoencoderKL`], the [`VQModel`] works in a quantized latent space.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Learning useful representations without supervision remains a key challenge in machine learning. In this paper, we propose a simple yet powerful generative model that learns such discrete representations. Our model, the Vector Quantised-Variational AutoEncoder (VQ-VAE), differs from VAEs in two key ways: the encoder network outputs discrete, rather than continuous, codes; and the prior is learnt rather than static. In order to learn a discrete latent representation, we incorporate ideas from vector quantisation (VQ). Using the VQ method allows the model to circumvent issues of "posterior collapse" -- where the latents are ignored when they are paired with a powerful autoregressive decoder -- typically observed in the VAE framework. Pairing these representations with an autoregressive prior, the model can generate high quality images, videos, and speech as well as doing high quality speaker conversion and unsupervised learning of phonemes, providing further evidence of the utility of the learnt representations.*

The `outputs` object is a [`~pipelines.ImagePipelineOutput`] which means it has an image attribute.
|
||||
|
||||
You can access each attribute as you normally would or with a keyword lookup, and if that attribute is not returned by the model, you will get `None`:
|
||||
|
||||
```python
|
||||
outputs.images
|
||||
outputs["images"]
|
||||
```
|
||||
|
||||
When considering the `outputs` object as a tuple, it only considers the attributes that don't have `None` values.
|
||||
For instance, retrieving an image by indexing into it returns the tuple `(outputs.images)`:
|
||||
|
||||
```python
|
||||
outputs[:1]
|
||||
```

# AltDiffusion
|
||||
|
||||
AltDiffusion was proposed in [AltCLIP: Altering the Language Encoder in CLIP for Extended Language Capabilities](https://huggingface.co/papers/2211.06679) by Zhongzhi Chen, Guang Liu, Bo-Wen Zhang, Fulong Ye, Qinghong Yang, Ledell Wu.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*In this work, we present a conceptually simple and effective method to train a strong bilingual multimodal representation model. Starting from the pretrained multimodal representation model CLIP released by OpenAI, we switched its text encoder with a pretrained multilingual text encoder XLM-R, and aligned both languages and image representations by a two-stage training schema consisting of teacher learning and contrastive learning. We validate our method through evaluations of a wide range of tasks. We set new state-of-the-art performances on a bunch of tasks including ImageNet-CN, Flicker30k- CN, and COCO-CN. Further, we obtain very close performances with CLIP on almost all tasks, suggesting that one can simply alter the text encoder in CLIP for extended capabilities such as multilingual understanding.*
|
||||
|
||||
## Tips
|
||||
|
||||
`AltDiffusion` is conceptually the same as [Stable Diffusion](./stable_diffusion/overview).

# Attend-and-Excite
|
||||
|
||||
Attend-and-Excite for Stable Diffusion was proposed in [Attend-and-Excite: Attention-Based Semantic Guidance for Text-to-Image Diffusion Models](https://attendandexcite.github.io/Attend-and-Excite/) and provides textual attention control over image generation.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Text-to-image diffusion models have recently received a lot of interest for their astonishing ability to produce high-fidelity images from text only. However, achieving one-shot generation that aligns with the user's intent is nearly impossible, yet small changes to the input prompt often result in very different images. This leaves the user with little semantic control. To put the user in control, we show how to interact with the diffusion process to flexibly steer it along semantic directions. This semantic guidance (SEGA) allows for subtle and extensive edits, changes in composition and style, as well as optimizing the overall artistic conception. We demonstrate SEGA's effectiveness on a variety of tasks and provide evidence for its versatility and flexibility.*

# AudioLDM
|
||||
|
||||
AudioLDM was proposed in [AudioLDM: Text-to-Audio Generation with Latent Diffusion Models](https://huggingface.co/papers/2301.12503) by Haohe Liu et al. Inspired by [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview), AudioLDM
|
||||
is a text-to-audio _latent diffusion model (LDM)_ that learns continuous audio representations from [CLAP](https://huggingface.co/docs/transformers/main/model_doc/clap)
|
||||
latents. AudioLDM takes a text prompt as input and predicts the corresponding audio. It can generate text-conditional
|
||||
sound effects, human speech and music.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Text-to-audio (TTA) system has recently gained attention for its ability to synthesize general audio based on text descriptions. However, previous studies in TTA have limited generation quality with high computational costs. In this study, we propose AudioLDM, a TTA system that is built on a latent space to learn the continuous audio representations from contrastive language-audio pretraining (CLAP) latents. The pretrained CLAP models enable us to train LDMs with audio embedding while providing text embedding as a condition during sampling. By learning the latent representations of audio signals and their compositions without modeling the cross-modal relationship, AudioLDM is advantageous in both generation quality and computational efficiency. Trained on AudioCaps with a single GPU, AudioLDM achieves state-of-the-art TTA performance measured by both objective and subjective metrics (e.g., frechet distance). Moreover, AudioLDM is the first TTA system that enables various text-guided audio manipulations (e.g., style transfer) in a zero-shot fashion. Our implementation and demos are available at https://audioldm.github.io.*

||||

||||

|
||||
|
||||
## Tips
|
||||
|
||||
When constructing a prompt, keep in mind:
|
||||
|
||||
* Descriptive prompt inputs work best; you can use adjectives to describe the sound (for example, "high quality" or "clear") and make the prompt context specific (for example, "water stream in a forest" instead of "stream").
|
||||
* It's best to use general terms like "cat" or "dog" instead of specific names or abstract objects the model may not be familiar with.
|
||||
|
||||
During inference:
|
||||
|
||||
* The _quality_ of the predicted audio sample can be controlled by the `num_inference_steps` argument; higher steps give higher quality audio at the expense of slower inference.
|
||||
* The _length_ of the predicted audio sample can be controlled by varying the `audio_length_in_s` argument.

||||

# AudioLDM 2
|
||||
|
||||
AudioLDM 2 was proposed in [AudioLDM 2: Learning Holistic Audio Generation with Self-supervised Pretraining](https://arxiv.org/abs/2308.05734)
|
||||
by Haohe Liu et al. AudioLDM 2 takes a text prompt as input and predicts the corresponding audio. It can generate
|
||||
text-conditional sound effects, human speech and music.
|
||||
|
||||
Inspired by [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview), AudioLDM 2
|
||||
is a text-to-audio _latent diffusion model (LDM)_ that learns continuous audio representations from text embeddings. Two
|
||||
text encoder models are used to compute the text embeddings from a prompt input: the text-branch of [CLAP](https://huggingface.co/docs/transformers/main/en/model_doc/clap)
|
||||
and the encoder of [Flan-T5](https://huggingface.co/docs/transformers/main/en/model_doc/flan-t5). These text embeddings
|
||||
are then projected to a shared embedding space by an [AudioLDM2ProjectionModel](https://huggingface.co/docs/diffusers/main/api/pipelines/audioldm2#diffusers.AudioLDM2ProjectionModel).
|
||||
A [GPT2](https://huggingface.co/docs/transformers/main/en/model_doc/gpt2) _language model (LM)_ is used to auto-regressively
|
||||
predict eight new embedding vectors, conditional on the projected CLAP and Flan-T5 embeddings. The generated embedding
|
||||
vectors and Flan-T5 text embeddings are used as cross-attention conditioning in the LDM. The [UNet](https://huggingface.co/docs/diffusers/main/en/api/pipelines/audioldm2#diffusers.AudioLDM2UNet2DConditionModel)
|
||||
of AudioLDM 2 is unique in the sense that it takes **two** cross-attention embeddings, as opposed to one cross-attention
|
||||
conditioning, as in most other LDMs.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*Although audio generation shares commonalities across different types of audio, such as speech, music, and sound effects, designing models for each type requires careful consideration of specific objectives and biases that can significantly differ from those of other types. To bring us closer to a unified perspective of audio generation, this paper proposes a framework that utilizes the same learning method for speech, music, and sound effect generation. Our framework introduces a general representation of audio, called language of audio (LOA). Any audio can be translated into LOA based on AudioMAE, a self-supervised pre-trained representation learning model. In the generation process, we translate any modalities into LOA by using a GPT-2 model, and we perform self-supervised audio generation learning with a latent diffusion model conditioned on LOA. The proposed framework naturally brings advantages such as in-context learning abilities and reusable self-supervised pretrained AudioMAE and latent diffusion models. Experiments on the major benchmarks of text-to-audio, text-to-music, and text-to-speech demonstrate new state-of-the-art or competitive performance to previous approaches.*

|
||||
|
||||
## Tips
|
||||
|
||||
### Choosing a checkpoint
|
||||
|
||||
AudioLDM2 comes in three variants. Two of these checkpoints are applicable to the general task of text-to-audio
|
||||
generation. The third checkpoint is trained exclusively on text-to-music generation.
|
||||
|
||||
All checkpoints share the same model size for the text encoders and VAE. They differ in the size and depth of the UNet.
|
||||
See table below for details on the three checkpoints:
|
||||
|
||||
| Checkpoint | Task | UNet Model Size | Total Model Size | Training Data / h |
|
||||
|-----------------------------------------------------------------|---------------|-----------------|------------------|-------------------|
|
||||
| [audioldm2](https://huggingface.co/cvssp/audioldm2) | Text-to-audio | 350M | 1.1B | 1150k |
|
||||
| [audioldm2-large](https://huggingface.co/cvssp/audioldm2-large) | Text-to-audio | 750M | 1.5B | 1150k |
|
||||
| [audioldm2-music](https://huggingface.co/cvssp/audioldm2-music) | Text-to-music | 350M | 1.1B | 665k |
|
||||
|
||||
### Constructing a prompt
|
||||
|
||||
* Descriptive prompt inputs work best: use adjectives to describe the sound (e.g. "high quality" or "clear") and make the prompt context specific (e.g. "water stream in a forest" instead of "stream").
|
||||
* It's best to use general terms like "cat" or "dog" instead of specific names or abstract objects the model may not be familiar with.
|
||||
* Using a **negative prompt** can significantly improve the quality of the generated waveform, by guiding the generation away from terms that correspond to poor quality audio. Try using a negative prompt of "Low quality."
|
||||
|
||||
### Controlling inference
|
||||
|
||||
* The _quality_ of the predicted audio sample can be controlled by the `num_inference_steps` argument; higher steps give higher quality audio at the expense of slower inference.
|
||||
* The _length_ of the predicted audio sample can be controlled by varying the `audio_length_in_s` argument.
|
||||
|
||||
### Evaluating generated waveforms:
|
||||
|
||||
* The quality of the generated waveforms can vary significantly based on the seed. Try generating with different seeds until you find a satisfactory generation
|
||||
* Multiple waveforms can be generated in one go: set `num_waveforms_per_prompt` to a value greater than 1. Automatic scoring will be performed between the generated waveforms and prompt text, and the audios ranked from best to worst accordingly.
|
||||
|
||||
The following example demonstrates how to construct good music generation using the aforementioned tips: [example](https://huggingface.co/docs/diffusers/main/en/api/pipelines/audioldm2#diffusers.AudioLDM2Pipeline.__call__.example).

# AutoPipeline
|
||||
|
||||
`AutoPipeline` is designed to:
|
||||
|
||||
1. make it easy for you to load a checkpoint for a task without knowing the specific pipeline class to use
|
||||
2. use multiple pipelines in your workflow
|
||||
|
||||
Based on the task, the `AutoPipeline` class automatically retrieves the relevant pipeline given the name or path to the pretrained weights with the `from_pretrained()` method.
|
||||
|
||||
To seamlessly switch between tasks with the same checkpoint without reallocating additional memory, use the `from_pipe()` method to transfer the components from the original pipeline to the new one.
|
||||
|
||||
```py
|
||||
from diffusers import AutoPipelineForText2Image
|
||||
import torch
|
||||
|
||||
pipeline = AutoPipelineForText2Image.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16, use_safetensors=True
|
||||
).to("cuda")
|
||||
prompt = "Astronaut in a jungle, cold color palette, muted colors, detailed, 8k"
|
||||
|
||||
image = pipeline(prompt, num_inference_steps=25).images[0]
|
||||
```

# Consistency Models
|
||||
|
||||
Consistency Models were proposed in [Consistency Models](https://huggingface.co/papers/2303.01469) by Yang Song, Prafulla Dhariwal, Mark Chen, and Ilya Sutskever.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Diffusion models have significantly advanced the fields of image, audio, and video generation, but they depend on an iterative sampling process that causes slow generation. To overcome this limitation, we propose consistency models, a new family of models that generate high quality samples by directly mapping noise to data. They support fast one-step generation by design, while still allowing multistep sampling to trade compute for sample quality. They also support zero-shot data editing, such as image inpainting, colorization, and super-resolution, without requiring explicit training on these tasks. Consistency models can be trained either by distilling pre-trained diffusion models, or as standalone generative models altogether. Through extensive experiments, we demonstrate that they outperform existing distillation techniques for diffusion models in one- and few-step sampling, achieving the new state-of-the-art FID of 3.55 on CIFAR-10 and 6.20 on ImageNet 64x64 for one-step generation. When trained in isolation, consistency models become a new family of generative models that can outperform existing one-step, non-adversarial generative models on standard benchmarks such as CIFAR-10, ImageNet 64x64 and LSUN 256x256. *

## Tips
|
||||
|
||||
For an additional speed-up, use `torch.compile` to generate multiple images in <1 second:
|
||||
|
||||
```diff
|
||||
import torch
|
||||
from diffusers import ConsistencyModelPipeline
|
||||
|
||||
device = "cuda"
|
||||
# Load the cd_bedroom256_lpips checkpoint.
|
||||
model_id_or_path = "openai/diffusers-cd_bedroom256_lpips"
|
||||
pipe = ConsistencyModelPipeline.from_pretrained(model_id_or_path, torch_dtype=torch.float16)
|
||||
pipe.to(device)
|
||||
|
||||
+ pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True)
|
||||
|
||||
# Multistep sampling
|
||||
# Timesteps can be explicitly specified; the particular timesteps below are from the original Github repo:
|
||||
# https://github.com/openai/consistency_models/blob/main/scripts/launch.sh#L83
|
||||
for _ in range(10):
|
||||
image = pipe(timesteps=[17, 0]).images[0]
|
||||
image.show()
|
||||
```

# ControlNet
|
||||
|
||||
ControlNet was introduced in [Adding Conditional Control to Text-to-Image Diffusion Models](https://huggingface.co/papers/2302.05543) by Lvmin Zhang and Maneesh Agrawala.
|
||||
|
||||
With a ControlNet model, you can provide an additional control image to condition and control Stable Diffusion generation. For example, if you provide a depth map, the ControlNet model generates an image that'll preserve the spatial information from the depth map. It is a more flexible and accurate way to control the image generation process.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*We present a neural network structure, ControlNet, to control pretrained large diffusion models to support additional input conditions. The ControlNet learns task-specific conditions in an end-to-end way, and the learning is robust even when the training dataset is small (< 50k). Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal devices. Alternatively, if powerful computation clusters are available, the model can scale to large amounts (millions to billions) of data. We report that large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc. This may enrich the methods to control large diffusion models and further facilitate related applications.*

# Cycle Diffusion
|
||||
|
||||
Cycle Diffusion is a text guided image-to-image generation model proposed in [Unifying Diffusion Models' Latent Space, with Applications to CycleDiffusion and Guidance](https://huggingface.co/papers/2210.05559) by Chen Henry Wu, Fernando De la Torre.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Diffusion models have achieved unprecedented performance in generative modeling. The commonly-adopted formulation of the latent code of diffusion models is a sequence of gradually denoised samples, as opposed to the simpler (e.g., Gaussian) latent space of GANs, VAEs, and normalizing flows. This paper provides an alternative, Gaussian formulation of the latent space of various diffusion models, as well as an invertible DPM-Encoder that maps images into the latent space. While our formulation is purely based on the definition of diffusion models, we demonstrate several intriguing consequences. (1) Empirically, we observe that a common latent space emerges from two diffusion models trained independently on related domains. In light of this finding, we propose CycleDiffusion, which uses DPM-Encoder for unpaired image-to-image translation. Furthermore, applying CycleDiffusion to text-to-image diffusion models, we show that large-scale text-to-image diffusion models can be used as zero-shot image-to-image editors. (2) One can guide pre-trained diffusion models and GANs by controlling the latent codes in a unified, plug-and-play formulation based on energy-based models. Using the CLIP model and a face recognition model as guidance, we demonstrate that diffusion models have better coverage of low-density sub-populations and individuals than GANs.*

[Denoising Diffusion Implicit Models](https://huggingface.co/papers/2010.02502) (DDIM) by Jiaming Song, Chenlin Meng and Stefano Ermon.
|

|
||||
The abstract from the paper is:
|
||||
|
||||
*Denoising diffusion probabilistic models (DDPMs) have achieved high quality image generation without adversarial training, yet they require simulating a Markov chain for many steps to produce a sample. To accelerate sampling, we present denoising diffusion implicit models (DDIMs), a more efficient class of iterative implicit probabilistic models with the same training procedure as DDPMs. In DDPMs, the generative process is defined as the reverse of a Markovian diffusion process. We construct a class of non-Markovian diffusion processes that lead to the same training objective, but whose reverse process can be much faster to sample from. We empirically demonstrate that DDIMs can produce high quality samples 10× to 50× faster in terms of wall-clock time compared to DDPMs, allow us to trade off computation for sample quality, and can perform semantically meaningful image interpolation directly in the latent space.*

# DDPM

[Denoising Diffusion Probabilistic Models](https://huggingface.co/papers/2006.11239) (DDPM) by Jonathan Ho, Ajay Jain and Pieter Abbeel proposes a diffusion based model of the same name. In the 🤗 Diffusers library, DDPM refers to the *discrete denoising scheduler* from the paper as well as the pipeline.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*We present high quality image synthesis results using diffusion probabilistic models, a class of latent variable models inspired by considerations from nonequilibrium thermodynamics. Our best results are obtained by training on a weighted variational bound designed according to a novel connection between diffusion probabilistic models and denoising score matching with Langevin dynamics, and our models naturally admit a progressive lossy decompression scheme that can be interpreted as a generalization of autoregressive decoding. On the unconditional CIFAR10 dataset, we obtain an Inception score of 9.46 and a state-of-the-art FID score of 3.17. On 256x256 LSUN, we obtain sample quality similar to ProgressiveGAN.*

# DeepFloyd IF
|
||||
|
||||
## Overview
|
||||
|
||||
DeepFloyd IF is a novel state-of-the-art open-source text-to-image model with a high degree of photorealism and language understanding.
|
||||
The model is a modular composed of a frozen text encoder and three cascaded pixel diffusion modules:
|
||||
- Stage 1: a base model that generates 64x64 px image based on text prompt,
|
||||
- Stage 2: a 64x64 px => 256x256 px super-resolution model, and a
|
||||
- Stage 3: a 256x256 px => 1024x1024 px super-resolution model
|
||||
Stage 1 and Stage 2 utilize a frozen text encoder based on the T5 transformer to extract text embeddings,
|
||||
which are then fed into a UNet architecture enhanced with cross-attention and attention pooling.
|
||||
Stage 3 is [Stability's x4 Upscaling model](https://huggingface.co/stabilityai/stable-diffusion-x4-upscaler).
|
||||
The result is a highly efficient model that outperforms current state-of-the-art models, achieving a zero-shot FID score of 6.66 on the COCO dataset.
|
||||
Our work underscores the potential of larger UNet architectures in the first stage of cascaded diffusion models and depicts a promising future for text-to-image synthesis.
|
||||
|
||||

### Text Guided Image-to-Image Generation
|
||||
|
||||
The same IF model weights can be used for text-guided image-to-image translation or image variation.
|
||||
In this case just make sure to load the weights using the [`IFInpaintingPipeline`] and [`IFInpaintingSuperResolutionPipeline`] pipelines.
|
||||
|
||||
**Note**: You can also directly move the weights of the text-to-image pipelines to the image-to-image pipelines
|
||||
without loading them twice by making use of the [`~DiffusionPipeline.components()`] function as explained [here](#converting-between-different-pipelines).

|

```
|
||||
|
||||
### Converting between different pipelines
|
||||
|
||||
In addition to being loaded with `from_pretrained`, Pipelines can also be loaded directly from each other.
|
||||
|
||||
```python
|
||||
from diffusers import IFPipeline, IFSuperResolutionPipeline
|
||||
|
||||
pipe_1 = IFPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0")
|
||||
pipe_2 = IFSuperResolutionPipeline.from_pretrained("DeepFloyd/IF-II-L-v1.0")
|
||||
|
||||
|
||||
from diffusers import IFImg2ImgPipeline, IFImg2ImgSuperResolutionPipeline
|
||||
|
||||
pipe_1 = IFImg2ImgPipeline(**pipe_1.components)
|
||||
pipe_2 = IFImg2ImgSuperResolutionPipeline(**pipe_2.components)
|
||||
|
||||
|
||||
from diffusers import IFInpaintingPipeline, IFInpaintingSuperResolutionPipeline
|
||||
|
||||
pipe_1 = IFInpaintingPipeline(**pipe_1.components)
|
||||
pipe_2 = IFInpaintingSuperResolutionPipeline(**pipe_2.components)
|
||||
```
|
||||
|
||||
### Optimizing for speed
|
||||
|
||||
The simplest optimization to run IF faster is to move all model components to the GPU.
|
||||
|
||||
```py
|
||||
pipe = DiffusionPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", variant="fp16", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
```
|
||||
|
||||
You can also run the diffusion process for a shorter number of timesteps.
|
||||
|
||||
This can either be done with the `num_inference_steps` argument
|
||||
|
||||
```py
|
||||
pipe("<prompt>", num_inference_steps=30)
|
||||
```
|
||||
|
||||
Or with the `timesteps` argument
|
||||
|
||||
```py
|
||||
from diffusers.pipelines.deepfloyd_if import fast27_timesteps
|
||||
|
||||
pipe("<prompt>", timesteps=fast27_timesteps)
|
||||
```
|
||||
|
||||
When doing image variation or inpainting, you can also decrease the number of timesteps
|
||||
with the strength argument. The strength argument is the amount of noise to add to
|
||||
the input image which also determines how many steps to run in the denoising process.
|
||||
A smaller number will vary the image less but run faster.
|
||||
|
||||
```py
|
||||
pipe = IFImg2ImgPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", variant="fp16", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
|
||||
image = pipe(image=image, prompt="<prompt>", strength=0.3).images
|
||||
```
|
||||
|
||||
You can also use [`torch.compile`](../../optimization/torch2.0). Note that we have not exhaustively tested `torch.compile`
|
||||
with IF and it might not give expected results.
|
||||
|
||||
```py
|
||||
import torch
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", variant="fp16", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
|
||||
pipe.text_encoder = torch.compile(pipe.text_encoder)
|
||||
pipe.unet = torch.compile(pipe.unet)
|
||||
```
|
||||
|
||||
### Optimizing for memory
|
||||
|
||||
When optimizing for GPU memory, we can use the standard diffusers cpu offloading APIs.
|
||||
|
||||
Either the model based CPU offloading,
|
||||
|
||||
```py
|
||||
pipe = DiffusionPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", variant="fp16", torch_dtype=torch.float16)
|
||||
pipe.enable_model_cpu_offload()
|
||||
```
|
||||
|
||||
or the more aggressive layer based CPU offloading.
|
||||
|
||||
```py
|
||||
pipe = DiffusionPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", variant="fp16", torch_dtype=torch.float16)
|
||||
pipe.enable_sequential_cpu_offload()
|
||||
```
|
||||
|
||||
Additionally, T5 can be loaded in 8bit precision
|
||||
|
||||
```py
|
||||
from transformers import T5EncoderModel
|
||||
|
||||
text_encoder = T5EncoderModel.from_pretrained(
|
||||
"DeepFloyd/IF-I-XL-v1.0", subfolder="text_encoder", device_map="auto", load_in_8bit=True, variant="8bit"
|
||||
)
|
||||
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"DeepFloyd/IF-I-XL-v1.0",
|
||||
text_encoder=text_encoder, # pass the previously instantiated 8bit text encoder
|
||||
unet=None,
|
||||
device_map="auto",
|
||||
)
|
||||
|
||||
prompt_embeds, negative_embeds = pipe.encode_prompt("<prompt>")
|
||||
```
|
||||
|
||||
For CPU RAM constrained machines like google colab free tier where we can't load all
|
||||
model components to the CPU at once, we can manually only load the pipeline with
|
||||
the text encoder or unet when the respective model components are needed.
|
||||
|
||||
```py
|
||||
from diffusers import IFPipeline, IFSuperResolutionPipeline
|
||||
import torch
|
||||
import gc
|
||||
from transformers import T5EncoderModel
|
||||
from diffusers.utils import pt_to_pil
|
||||

|
||||
"DeepFloyd/IF-I-XL-v1.0", subfolder="text_encoder", device_map="auto", load_in_8bit=True, variant="8bit"
|
||||
)
|
||||
|
||||
# text to image
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"DeepFloyd/IF-I-XL-v1.0",
|
||||
text_encoder=text_encoder, # pass the previously instantiated 8bit text encoder
|
||||
unet=None,
|
||||
device_map="auto",
|
||||
)
|
||||
|
||||
prompt = 'a photo of a kangaroo wearing an orange hoodie and blue sunglasses standing in front of the eiffel tower holding a sign that says "very deep learning"'
|
||||
prompt_embeds, negative_embeds = pipe.encode_prompt(prompt)
|
||||
|
||||
# Remove the pipeline so we can re-load the pipeline with the unet
|
||||
del text_encoder
|
||||
del pipe
|
||||
gc.collect()
|
||||
torch.cuda.empty_cache()
|
||||
|
||||
pipe = IFPipeline.from_pretrained(
|
||||
"DeepFloyd/IF-I-XL-v1.0", text_encoder=None, variant="fp16", torch_dtype=torch.float16, device_map="auto"
|
||||
)
|
||||
|
||||
generator = torch.Generator().manual_seed(0)
|
||||
image = pipe(
|
||||
prompt_embeds=prompt_embeds,
|
||||
negative_prompt_embeds=negative_embeds,
|

output_type="pt",

|
||||

|

# DiffEdit
|
||||
|
||||
[DiffEdit: Diffusion-based semantic image editing with mask guidance](https://huggingface.co/papers/2210.11427) is by Guillaume Couairon, Jakob Verbeek, Holger Schwenk, and Matthieu Cord.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Image generation has recently seen tremendous advances, with diffusion models allowing to synthesize convincing images for a large variety of text prompts. In this article, we propose DiffEdit, a method to take advantage of text-conditioned diffusion models for the task of semantic image editing, where the goal is to edit an image based on a text query. Semantic image editing is an extension of image generation, with the additional constraint that the generated image should be as similar as possible to a given input image. Current editing methods based on diffusion models usually require to provide a mask, making the task much easier by treating it as a conditional inpainting task. In contrast, our main contribution is able to automatically generate a mask highlighting regions of the input image that need to be edited, by contrasting predictions of a diffusion model conditioned on different text prompts. Moreover, we rely on latent inference to preserve content in those regions of interest and show excellent synergies with mask-based diffusion. DiffEdit achieves state-of-the-art editing performance on ImageNet. In addition, we evaluate semantic image editing in more challenging settings, using images from the COCO dataset as well as text-based generated images.*

|
||||
## Tips
|
||||
|
||||
* The pipeline can generate masks that can be fed into other inpainting pipelines.
|
||||
* In order to generate an image using this pipeline, both an image mask (source and target prompts can be manually specified or generated, and passed to [`~StableDiffusionDiffEditPipeline.generate_mask`])
|
||||
and a set of partially inverted latents (generated using [`~StableDiffusionDiffEditPipeline.invert`]) _must_ be provided as arguments when calling the pipeline to generate the final edited image.
|
||||
* The function [`~StableDiffusionDiffEditPipeline.generate_mask`] exposes two prompt arguments, `source_prompt` and `target_prompt`
|
||||
that let you control the locations of the semantic edits in the final image to be generated. Let's say,
|
||||
you wanted to translate from "cat" to "dog". In this case, the edit direction will be "cat -> dog". To reflect
|
||||
this in the generated mask, you simply have to set the embeddings related to the phrases including "cat" to
|
||||
`source_prompt` and "dog" to `target_prompt`.
|
||||
* When generating partially inverted latents using `invert`, assign a caption or text embedding describing the
|
||||
overall image to the `prompt` argument to help guide the inverse latent sampling process. In most cases, the
|
||||
source concept is sufficently descriptive to yield good results, but feel free to explore alternatives.
|
||||
* When calling the pipeline to generate the final edited image, assign the source concept to `negative_prompt`
|
||||
and the target concept to `prompt`. Taking the above example, you simply have to set the embeddings related to
|
||||
the phrases including "cat" to `negative_prompt` and "dog" to `prompt`.
|
||||
* If you wanted to reverse the direction in the example above, i.e., "dog -> cat", then it's recommended to:
|
||||
* Swap the `source_prompt` and `target_prompt` in the arguments to `generate_mask`.
|
||||
* Change the input prompt in [`~StableDiffusionDiffEditPipeline.invert`] to include "dog".
|
||||
* Swap the `prompt` and `negative_prompt` in the arguments to call the pipeline to generate the final edited image.
|
||||
* The source and target prompts, or their corresponding embeddings, can also be automatically generated. Please refer to the [DiffEdit](/using-diffusers/diffedit) guide for more details.

[Scalable Diffusion Models with Transformers](https://huggingface.co/papers/2212.09748) (DiT) is by William Peebles and Saining Xie.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*We explore a new class of diffusion models based on the transformer architecture. We train latent diffusion models of images, replacing the commonly-used U-Net backbone with a transformer that operates on latent patches. We analyze the scalability of our Diffusion Transformers (DiTs) through the lens of forward pass complexity as measured by Gflops. We find that DiTs with higher Gflops -- through increased transformer depth/width or increased number of input tokens -- consistently have lower FID. In addition to possessing good scalability properties, our largest DiT-XL/2 models outperform all prior diffusion models on the class-conditional ImageNet 512x512 and 256x256 benchmarks, achieving a state-of-the-art FID of 2.27 on the latter.*

# Kandinsky
|
||||
|
||||
## Overview
|
||||
|
||||
Kandinsky inherits best practices from [DALL-E 2](https://huggingface.co/papers/2204.06125) and [Latent Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/latent_diffusion), while introducing some new ideas.
|
||||
|
||||
It uses [CLIP](https://huggingface.co/docs/transformers/model_doc/clip) for encoding images and text, and a diffusion image prior (mapping) between latent spaces of CLIP modalities. This approach enhances the visual performance of the model and unveils new horizons in blending images and text-guided image manipulation.
|
||||
|
||||
The Kandinsky model is created by [Arseniy Shakhmatov](https://github.com/cene555), [Anton Razzhigaev](https://github.com/razzant), [Aleksandr Nikolich](https://github.com/AlexWortega), [Igor Pavlov](https://github.com/boomb0om), [Andrey Kuznetsov](https://github.com/kuznetsoffandrey) and [Denis Dimitrov](https://github.com/denndimitrov). The original codebase can be found [here](https://github.com/ai-forever/Kandinsky-2)
|
||||
|
||||
|
||||
## Usage example
|
||||
|
||||
In the following, we will walk you through some examples of how to use the Kandinsky pipelines to create some visually aesthetic artwork.
|
||||
|
||||
### Text-to-Image Generation
|
||||
|
||||
For text-to-image generation, we need to use both [`KandinskyPriorPipeline`] and [`KandinskyPipeline`].
|
||||
The first step is to encode text prompts with CLIP and then diffuse the CLIP text embeddings to CLIP image embeddings,
|
||||
as first proposed in [DALL-E 2](https://cdn.openai.com/papers/dall-e-2.pdf).
|
||||
Let's throw a fun prompt at Kandinsky to see what it comes up with.
|
||||
|
||||
```py
|
||||
prompt = "A alien cheeseburger creature eating itself, claymation, cinematic, moody lighting"
|
||||
```
|
||||
|
||||
First, let's instantiate the prior pipeline and the text-to-image pipeline. Both
|
||||
pipelines are diffusion models.
|
||||
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipe_prior = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-1-prior", torch_dtype=torch.float16)
|
||||
pipe_prior.to("cuda")
|
||||
|
||||
t2i_pipe = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
t2i_pipe.to("cuda")
|
||||
```
|
||||
|
||||
<Tip warning={true}>
|
||||
|
||||
By default, the text-to-image pipeline use [`DDIMScheduler`], you can change the scheduler to [`DDPMScheduler`]
|
||||
|
||||
```py
|
||||
scheduler = DDPMScheduler.from_pretrained("kandinsky-community/kandinsky-2-1", subfolder="ddpm_scheduler")
|
||||
t2i_pipe = DiffusionPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-1", scheduler=scheduler, torch_dtype=torch.float16
|
||||
)
|
||||
t2i_pipe.to("cuda")
|
||||
```
|
||||
|
||||
</Tip>
|
||||
|
||||
Now we pass the prompt through the prior to generate image embeddings. The prior
|
||||
returns both the image embeddings corresponding to the prompt and negative/unconditional image
|
||||
embeddings corresponding to an empty string.
|
||||
|
||||
```py
|
||||
image_embeds, negative_image_embeds = pipe_prior(prompt, guidance_scale=1.0).to_tuple()
|
||||
```
|
||||
|
||||
<Tip warning={true}>
|
||||
|
||||
The text-to-image pipeline expects both `image_embeds`, `negative_image_embeds` and the original
|
||||
`prompt` as the text-to-image pipeline uses another text encoder to better guide the second diffusion
|
||||
process of `t2i_pipe`.
|
||||
|
||||
By default, the prior returns unconditioned negative image embeddings corresponding to the negative prompt of `""`.
|
||||
For better results, you can also pass a `negative_prompt` to the prior. This will increase the effective batch size
|
||||
of the prior by a factor of 2.
|
||||
|
||||
```py
|
||||
prompt = "A alien cheeseburger creature eating itself, claymation, cinematic, moody lighting"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
image_embeds, negative_image_embeds = pipe_prior(prompt, negative_prompt, guidance_scale=1.0).to_tuple()
|
||||
```
|
||||
|
||||
</Tip>
|
||||
|
||||
|
||||
Next, we can pass the embeddings as well as the prompt to the text-to-image pipeline. Remember that
|
||||
in case you are using a customized negative prompt, that you should pass this one also to the text-to-image pipelines
|
||||
with `negative_prompt=negative_prompt`:
|
||||
|
||||
```py
|
||||
image = t2i_pipe(
|
||||
prompt, image_embeds=image_embeds, negative_image_embeds=negative_image_embeds, height=768, width=768
|
||||
).images[0]
|
||||
image.save("cheeseburger_monster.png")
|
||||
```
|
||||
|
||||
One cheeseburger monster coming up! Enjoy!
|
||||
|
||||

|
||||
|
||||
<Tip>
|
||||
|
||||
We also provide an end-to-end Kandinsky pipeline [`KandinskyCombinedPipeline`], which combines both the prior pipeline and text-to-image pipeline, and lets you perform inference in a single step. You can create the combined pipeline with the [`~AutoPipelineForText2Image.from_pretrained`] method
|
||||
|
||||
```python
|
||||
from diffusers import AutoPipelineForText2Image
|
||||
import torch
|
||||
|
||||
pipe = AutoPipelineForText2Image.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16
|
||||
)
|
||||
pipe.enable_model_cpu_offload()
|
||||
```
|
||||
|
||||
Under the hood, it will automatically load both [`KandinskyPriorPipeline`] and [`KandinskyPipeline`]. To generate images, you no longer need to call both pipelines and pass the outputs from one to another. You only need to call the combined pipeline once. You can set different `guidance_scale` and `num_inference_steps` for the prior pipeline with the `prior_guidance_scale` and `prior_num_inference_steps` arguments.
|
||||
|
||||
```python
|
||||
prompt = "A alien cheeseburger creature eating itself, claymation, cinematic, moody lighting"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
image = pipe(prompt=prompt, negative_prompt=negative_prompt, prior_guidance_scale =1.0, guidance_scacle = 4.0, height=768, width=768).images[0]
|
||||
```
|
||||
</Tip>
|
||||
|
||||
The Kandinsky model works extremely well with creative prompts. Here is some of the amazing art that can be created using the exact same process but with different prompts.
|
||||
|
||||
```python
|
||||
prompt = "bird eye view shot of a full body woman with cyan light orange magenta makeup, digital art, long braided hair her face separated by makeup in the style of yin Yang surrealism, symmetrical face, real image, contrasting tone, pastel gradient background"
|
||||
```
|
||||

|
||||
|
||||
```python
|
||||
prompt = "A car exploding into colorful dust"
|
||||
```
|
||||

|
||||
|
||||
```python
|
||||
prompt = "editorial photography of an organic, almost liquid smoke style armchair"
|
||||
```
|
||||

|
||||
|
||||
```python
|
||||
prompt = "birds eye view of a quilted paper style alien planet landscape, vibrant colours, Cinematic lighting"
|
||||
```
|
||||

|
||||
|
||||
|
||||
|
||||
### Text Guided Image-to-Image Generation
|
||||
|
||||
The same Kandinsky model weights can be used for text-guided image-to-image translation. In this case, just make sure to load the weights using the [`KandinskyImg2ImgPipeline`] pipeline.
|
||||
|
||||
**Note**: You can also directly move the weights of the text-to-image pipelines to the image-to-image pipelines
|
||||
without loading them twice by making use of the [`~DiffusionPipeline.components`] function as explained [here](#converting-between-different-pipelines).
|
||||
|
||||
Let's download an image.
|
||||
|
||||
```python
|
||||
from PIL import Image
|
||||
import requests
|
||||
from io import BytesIO
|
||||
|
||||
# download image
|
||||
url = "https://raw.githubusercontent.com/CompVis/stable-diffusion/main/assets/stable-samples/img2img/sketch-mountains-input.jpg"
|
||||
response = requests.get(url)
|
||||
original_image = Image.open(BytesIO(response.content)).convert("RGB")
|
||||
original_image = original_image.resize((768, 512))
|
||||
```
|
||||
|
||||

|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import KandinskyImg2ImgPipeline, KandinskyPriorPipeline
|
||||
|
||||
# create prior
|
||||
pipe_prior = KandinskyPriorPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-1-prior", torch_dtype=torch.float16
|
||||
)
|
||||
pipe_prior.to("cuda")
|
||||
|
||||
# create img2img pipeline
|
||||
pipe = KandinskyImg2ImgPipeline.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
|
||||
prompt = "A fantasy landscape, Cinematic lighting"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
image_embeds, negative_image_embeds = pipe_prior(prompt, negative_prompt).to_tuple()
|
||||
|
||||
out = pipe(
|
||||
prompt,
|
||||
image=original_image,
|
||||
image_embeds=image_embeds,
|
||||
negative_image_embeds=negative_image_embeds,
|
||||
height=768,
|
||||
width=768,
|
||||
strength=0.3,
|
||||
)
|
||||
|
||||
out.images[0].save("fantasy_land.png")
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
<Tip>
|
||||
|
||||
You can also use the [`KandinskyImg2ImgCombinedPipeline`] for end-to-end image-to-image generation with Kandinsky 2.1
|
||||
|
||||
```python
|
||||
from diffusers import AutoPipelineForImage2Image
|
||||
import torch
|
||||
import requests
|
||||
from io import BytesIO
|
||||
from PIL import Image
|
||||
import os
|
||||
|
||||
pipe = AutoPipelineForImage2Image.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
pipe.enable_model_cpu_offload()
|
||||
|
||||
prompt = "A fantasy landscape, Cinematic lighting"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
url = "https://raw.githubusercontent.com/CompVis/stable-diffusion/main/assets/stable-samples/img2img/sketch-mountains-input.jpg"
|
||||
|
||||
response = requests.get(url)
|
||||
original_image = Image.open(BytesIO(response.content)).convert("RGB")
|
||||
original_image.thumbnail((768, 768))
|
||||
|
||||
image = pipe(prompt=prompt, image=original_image, strength=0.3).images[0]
|
||||
```
|
||||
</Tip>
|
||||
|
||||
### Text Guided Inpainting Generation
|
||||
|
||||
You can use [`KandinskyInpaintPipeline`] to edit images. In this example, we will add a hat to the portrait of a cat.
|
||||
|
||||
```py
|
||||
from diffusers import KandinskyInpaintPipeline, KandinskyPriorPipeline
|
||||
from diffusers.utils import load_image
|
||||
import torch
|
||||
import numpy as np
|
||||
|
||||
pipe_prior = KandinskyPriorPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-1-prior", torch_dtype=torch.float16
|
||||
)
|
||||
pipe_prior.to("cuda")
|
||||
|
||||
prompt = "a hat"
|
||||
prior_output = pipe_prior(prompt)
|
||||
|
||||
pipe = KandinskyInpaintPipeline.from_pretrained("kandinsky-community/kandinsky-2-1-inpaint", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
|
||||
init_image = load_image(
|
||||
"https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main" "/kandinsky/cat.png"
|
||||
)
|
||||
|
||||
mask = np.zeros((768, 768), dtype=np.float32)
|
||||
# Let's mask out an area above the cat's head
|
||||
mask[:250, 250:-250] = 1
|
||||
|
||||
out = pipe(
|
||||
prompt,
|
||||
image=init_image,
|
||||
mask_image=mask,
|
||||
**prior_output,
|
||||
height=768,
|
||||
width=768,
|
||||
num_inference_steps=150,
|
||||
)
|
||||
|
||||
image = out.images[0]
|
||||
image.save("cat_with_hat.png")
|
||||
```
|
||||

|
||||
|
||||
<Tip>
|
||||
|
||||
To use the [`KandinskyInpaintCombinedPipeline`] to perform end-to-end image inpainting generation, you can run below code instead
|
||||
|
||||
```python
|
||||
from diffusers import AutoPipelineForInpainting
|
||||
|
||||
pipe = AutoPipelineForInpainting.from_pretrained("kandinsky-community/kandinsky-2-1-inpaint", torch_dtype=torch.float16)
|
||||
pipe.enable_model_cpu_offload()
|
||||
image = pipe(prompt=prompt, image=original_image, mask_image=mask).images[0]
|
||||
```
|
||||
</Tip>
|
||||
|
||||
🚨🚨🚨 __Breaking change for Kandinsky Mask Inpainting__ 🚨🚨🚨
|
||||
|
||||
We introduced a breaking change for Kandinsky inpainting pipeline in the following pull request: https://github.com/huggingface/diffusers/pull/4207. Previously we accepted a mask format where black pixels represent the masked-out area. This is inconsistent with all other pipelines in diffusers. We have changed the mask format in Knaindsky and now using white pixels instead.
|
||||
Please upgrade your inpainting code to follow the above. If you are using Kandinsky Inpaint in production. You now need to change the mask to:
|
||||
|
||||
```python
|
||||
# For PIL input
|
||||
import PIL.ImageOps
|
||||
mask = PIL.ImageOps.invert(mask)
|
||||
|
||||
# For PyTorch and Numpy input
|
||||
mask = 1 - mask
|
||||
```
|
||||
|
||||
### Interpolate
|
||||
|
||||
The [`KandinskyPriorPipeline`] also comes with a cool utility function that will allow you to interpolate the latent space of different images and texts super easily. Here is an example of how you can create an Impressionist-style portrait for your pet based on "The Starry Night".
|
||||
|
||||
Note that you can interpolate between texts and images - in the below example, we passed a text prompt "a cat" and two images to the `interplate` function, along with a `weights` variable containing the corresponding weights for each condition we interplate.
|
||||
|
||||
```python
|
||||
from diffusers import KandinskyPriorPipeline, KandinskyPipeline
|
||||
from diffusers.utils import load_image
|
||||
import PIL
|
||||
|
||||
import torch
|
||||
|
||||
pipe_prior = KandinskyPriorPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-1-prior", torch_dtype=torch.float16
|
||||
)
|
||||
pipe_prior.to("cuda")
|
||||
|
||||
img1 = load_image(
|
||||
"https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main" "/kandinsky/cat.png"
|
||||
)
|
||||
|
||||
img2 = load_image(
|
||||
"https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main" "/kandinsky/starry_night.jpeg"
|
||||
)
|
||||
|
||||
# add all the conditions we want to interpolate, can be either text or image
|
||||
images_texts = ["a cat", img1, img2]
|
||||
|
||||
# specify the weights for each condition in images_texts
|
||||
weights = [0.3, 0.3, 0.4]
|
||||
|
||||
# We can leave the prompt empty
|
||||
prompt = ""
|
||||
prior_out = pipe_prior.interpolate(images_texts, weights)
|
||||
|
||||
pipe = KandinskyPipeline.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
pipe.to("cuda")
|
||||
|
||||
image = pipe(prompt, **prior_out, height=768, width=768).images[0]
|
||||
|
||||
image.save("starry_cat.png")
|
||||
```
|
||||

|
||||
|
||||
## Optimization
|
||||
|
||||
Running Kandinsky in inference requires running both a first prior pipeline: [`KandinskyPriorPipeline`]
|
||||
and a second image decoding pipeline which is one of [`KandinskyPipeline`], [`KandinskyImg2ImgPipeline`], or [`KandinskyInpaintPipeline`].
|
||||
|
||||
The bulk of the computation time will always be the second image decoding pipeline, so when looking
|
||||
into optimizing the model, one should look into the second image decoding pipeline.
|
||||
|
||||
When running with PyTorch < 2.0, we strongly recommend making use of [`xformers`](https://github.com/facebookresearch/xformers)
|
||||
to speed-up the optimization. This can be done by simply running:
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
t2i_pipe = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
t2i_pipe.enable_xformers_memory_efficient_attention()
|
||||
```
|
||||
|
||||
When running on PyTorch >= 2.0, PyTorch's SDPA attention will automatically be used. For more information on
|
||||
PyTorch's SDPA, feel free to have a look at [this blog post](https://pytorch.org/blog/accelerated-diffusers-pt-20/).
|

To have explicit control , you can also manually set the pipeline to use PyTorch's 2.0 efficient attention:
|

```py
|

from diffusers.models.attention_processor import AttnAddedKVProcessor2_0
|
||||
|
||||
t2i_pipe.unet.set_attn_processor(AttnAddedKVProcessor2_0())
|
||||
```
|
||||
|
||||
The slowest and most memory intense attention processor is the default `AttnAddedKVProcessor` processor.
|
||||
We do **not** recommend using it except for testing purposes or cases where very high determistic behaviour is desired.
|
||||
You can set it with:
|
||||
|
||||
```py
|
||||
from diffusers.models.attention_processor import AttnAddedKVProcessor
|
||||
|
||||
t2i_pipe.unet.set_attn_processor(AttnAddedKVProcessor())
|
||||
```
|
||||
|
||||
With PyTorch >= 2.0, you can also use Kandinsky with `torch.compile` which depending
|
||||
on your hardware can signficantly speed-up your inference time once the model is compiled.
|
||||
To use Kandinsksy with `torch.compile`, you can do:
|
||||
|
||||
```py
|
||||
t2i_pipe.unet.to(memory_format=torch.channels_last)
|
||||
t2i_pipe.unet = torch.compile(t2i_pipe.unet, mode="reduce-overhead", fullgraph=True)
|
||||
```
|
||||
|
||||
After compilation you should see a very fast inference time. For more information,

# Kandinsky 2.2
|
||||
|
||||
The Kandinsky 2.2 release includes robust new text-to-image models that support text-to-image generation, image-to-image generation, image interpolation, and text-guided image inpainting. The general workflow to perform these tasks using Kandinsky 2.2 is the same as in Kandinsky 2.1. First, you will need to use a prior pipeline to generate image embeddings based on your text prompt, and then use one of the image decoding pipelines to generate the output image. The only difference is that in Kandinsky 2.2, all of the decoding pipelines no longer accept the `prompt` input, and the image generation process is conditioned with only `image_embeds` and `negative_image_embeds`.
|
||||
|
||||
Same as with Kandinsky 2.1, the easiest way to perform text-to-image generation is to use the combined Kandinsky pipeline. This process is exactly the same as Kandinsky 2.1. All you need to do is to replace the Kandinsky 2.1 checkpoint with 2.2.
|
||||
|
||||
```python
|
||||
from diffusers import AutoPipelineForText2Image
|
||||
import torch
|
||||
|
||||
pipe = AutoPipelineForText2Image.from_pretrained("kandinsky-community/kandinsky-2-2-decoder", torch_dtype=torch.float16)
|
||||
pipe.enable_model_cpu_offload()
|
||||
|
||||
prompt = "A alien cheeseburger creature eating itself, claymation, cinematic, moody lighting"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
image = pipe(prompt=prompt, negative_prompt=negative_prompt, prior_guidance_scale =1.0, height=768, width=768).images[0]
|
||||
```
|
||||
|
||||
Now, let's look at an example where we take separate steps to run the prior pipeline and text-to-image pipeline. This way, we can understand what's happening under the hood and how Kandinsky 2.2 differs from Kandinsky 2.1.
|
||||
|
||||
First, let's create the prior pipeline and text-to-image pipeline with Kandinsky 2.2 checkpoints.
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipe_prior = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-2-prior", torch_dtype=torch.float16)
|
||||
pipe_prior.to("cuda")
|
||||
|
||||
t2i_pipe = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-2-decoder", torch_dtype=torch.float16)
|
||||
t2i_pipe.to("cuda")
|
||||
```
|
||||
|
||||
You can then use `pipe_prior` to generate image embeddings.
|
||||
|
||||
```python
|
||||
prompt = "portrait of a women, blue eyes, cinematic"
|
||||
negative_prompt = "low quality, bad quality"
|
||||
|
||||
image_embeds, negative_image_embeds = pipe_prior(prompt, guidance_scale=1.0).to_tuple()
|
||||
```
|
||||
|
||||
Now you can pass these embeddings to the text-to-image pipeline. When using Kandinsky 2.2 you don't need to pass the `prompt` (but you do with the previous version, Kandinsky 2.1).
|
||||
|
||||
```
|
||||
image = t2i_pipe(image_embeds=image_embeds, negative_image_embeds=negative_image_embeds, height=768, width=768).images[
|
||||
0
|
||||
]
|
||||
image.save("portrait.png")
|
||||
```
|
||||

|
||||
|
||||
We used the text-to-image pipeline as an example, but the same process applies to all decoding pipelines in Kandinsky 2.2. For more information, please refer to our API section for each pipeline.
|
||||
|
||||
### Text-to-Image Generation with ControlNet Conditioning
|
||||
|
||||
In the following, we give a simple example of how to use [`KandinskyV22ControlnetPipeline`] to add control to the text-to-image generation with a depth image.
|
||||
|
||||
First, let's take an image and extract its depth map.
|
||||
|
||||
```python
|
||||
from diffusers.utils import load_image
|
||||
|
||||
img = load_image(
|
||||
"https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main/kandinskyv22/cat.png"
|
||||
).resize((768, 768))
|
||||
```
|
||||

|
||||
|
||||
We can use the `depth-estimation` pipeline from transformers to process the image and retrieve its depth map.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import numpy as np
|
||||
|
||||
from transformers import pipeline
|
||||
from diffusers.utils import load_image
|
||||
|
||||
|
||||
def make_hint(image, depth_estimator):
|
||||
image = depth_estimator(image)["depth"]
|
||||
image = np.array(image)
|
||||
image = image[:, :, None]
|
||||
image = np.concatenate([image, image, image], axis=2)
|
||||
detected_map = torch.from_numpy(image).float() / 255.0
|
||||
hint = detected_map.permute(2, 0, 1)
|
||||
return hint
|
||||
|
||||
|
||||
depth_estimator = pipeline("depth-estimation")
|
||||
hint = make_hint(img, depth_estimator).unsqueeze(0).half().to("cuda")
|
||||
```
|
||||
Now, we load the prior pipeline and the text-to-image controlnet pipeline
|
||||
|
||||
```python
|
||||
from diffusers import KandinskyV22PriorPipeline, KandinskyV22ControlnetPipeline
|
||||
|
||||
pipe_prior = KandinskyV22PriorPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-2-prior", torch_dtype=torch.float16
|
||||
)
|
||||
pipe_prior = pipe_prior.to("cuda")
|
||||
|
||||
pipe = KandinskyV22ControlnetPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-2-controlnet-depth", torch_dtype=torch.float16
|
||||
)
|
||||
pipe = pipe.to("cuda")
|
||||
```
|
||||
|
||||
We pass the prompt and negative prompt through the prior to generate image embeddings
|
||||
|
||||
```python
|
||||
prompt = "A robot, 4k photo"
|
||||
|
||||
negative_prior_prompt = "lowres, text, error, cropped, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, out of frame, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck, username, watermark, signature"
|
||||
|
||||
generator = torch.Generator(device="cuda").manual_seed(43)
|
||||
image_emb, zero_image_emb = pipe_prior(
|
||||
prompt=prompt, negative_prompt=negative_prior_prompt, generator=generator
|
||||
).to_tuple()
|
||||
```
|
||||
|
||||
Now we can pass the image embeddings and the depth image we extracted to the controlnet pipeline. With Kandinsky 2.2, only prior pipelines accept `prompt` input. You do not need to pass the prompt to the controlnet pipeline.
|
||||
|
||||
```python
|
||||
images = pipe(
|
||||
image_embeds=image_emb,
|
||||
negative_image_embeds=zero_image_emb,
|
||||
hint=hint,
|
||||
num_inference_steps=50,
|
||||
generator=generator,
|
||||
height=768,
|
||||
width=768,
|
||||
).images
|
||||
|
||||
images[0].save("robot_cat.png")
|
||||
```
|
||||
|
||||
The output image looks as follow:
|
||||

|
||||
|
||||
### Image-to-Image Generation with ControlNet Conditioning
|
||||
|
||||
Kandinsky 2.2 also includes a [`KandinskyV22ControlnetImg2ImgPipeline`] that will allow you to add control to the image generation process with both the image and its depth map. This pipeline works really well with [`KandinskyV22PriorEmb2EmbPipeline`], which generates image embeddings based on both a text prompt and an image.
|
||||
|
||||
For our robot cat example, we will pass the prompt and cat image together to the prior pipeline to generate an image embedding. We will then use that image embedding and the depth map of the cat to further control the image generation process.
|
||||
|
||||
We can use the same cat image and its depth map from the last example.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import numpy as np
|
||||
|
||||
from diffusers import KandinskyV22PriorEmb2EmbPipeline, KandinskyV22ControlnetImg2ImgPipeline
|
||||
from diffusers.utils import load_image
|
||||
from transformers import pipeline
|
||||
|
||||
img = load_image(
|
||||
"https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main" "/kandinskyv22/cat.png"
|
||||
).resize((768, 768))
|
||||
|
||||
|
||||
def make_hint(image, depth_estimator):
|
||||
image = depth_estimator(image)["depth"]
|
||||
image = np.array(image)
|
||||
image = image[:, :, None]
|
||||
image = np.concatenate([image, image, image], axis=2)
|
||||
detected_map = torch.from_numpy(image).float() / 255.0
|
||||
hint = detected_map.permute(2, 0, 1)
|
||||
return hint
|
||||
|
||||
|
||||
depth_estimator = pipeline("depth-estimation")
|
||||
hint = make_hint(img, depth_estimator).unsqueeze(0).half().to("cuda")
|
||||
|
||||
pipe_prior = KandinskyV22PriorEmb2EmbPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-2-prior", torch_dtype=torch.float16
|
||||
)
|
||||
pipe_prior = pipe_prior.to("cuda")
|
||||
|
||||
pipe = KandinskyV22ControlnetImg2ImgPipeline.from_pretrained(
|
||||
"kandinsky-community/kandinsky-2-2-controlnet-depth", torch_dtype=torch.float16
|
||||
)
|
||||
pipe = pipe.to("cuda")
|
||||
|
||||
prompt = "A robot, 4k photo"
|
||||
negative_prior_prompt = "lowres, text, error, cropped, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, out of frame, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad anatomy, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck, username, watermark, signature"
|
||||
|
||||
generator = torch.Generator(device="cuda").manual_seed(43)
|
||||
|
||||
# run prior pipeline
|
||||
|
||||
img_emb = pipe_prior(prompt=prompt, image=img, strength=0.85, generator=generator)
|
||||
negative_emb = pipe_prior(prompt=negative_prior_prompt, image=img, strength=1, generator=generator)
|
||||
|
||||
# run controlnet img2img pipeline
|
||||
images = pipe(
|
||||
image=img,
|
||||
strength=0.5,
|
||||
image_embeds=img_emb.image_embeds,
|
||||
negative_image_embeds=negative_emb.image_embeds,
|
||||
hint=hint,
|
||||
num_inference_steps=50,
|
||||
generator=generator,
|
||||
height=768,
|
||||
width=768,
|
||||
).images
|
||||
|
||||
images[0].save("robot_cat.png")
|
||||
```
|
||||
|
||||
Here is the output. Compared with the output from our text-to-image controlnet example, it kept a lot more cat facial details from the original image and worked into the robot style we asked for.
|
||||
|
||||

|
||||
|
||||
## Optimization
|
||||
|
||||
Running Kandinsky in inference requires running both a first prior pipeline: [`KandinskyPriorPipeline`]
|
||||
and a second image decoding pipeline which is one of [`KandinskyPipeline`], [`KandinskyImg2ImgPipeline`], or [`KandinskyInpaintPipeline`].
|
||||
|
||||
The bulk of the computation time will always be the second image decoding pipeline, so when looking
|
||||
into optimizing the model, one should look into the second image decoding pipeline.
|
||||
|
||||
When running with PyTorch < 2.0, we strongly recommend making use of [`xformers`](https://github.com/facebookresearch/xformers)
|
||||
to speed-up the optimization. This can be done by simply running:
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
t2i_pipe = DiffusionPipeline.from_pretrained("kandinsky-community/kandinsky-2-1", torch_dtype=torch.float16)
|
||||
t2i_pipe.enable_xformers_memory_efficient_attention()
|
||||
```
|
||||
|
||||
When running on PyTorch >= 2.0, PyTorch's SDPA attention will automatically be used. For more information on
|
||||
PyTorch's SDPA, feel free to have a look at [this blog post](https://pytorch.org/blog/accelerated-diffusers-pt-20/).
|
||||
|
||||
To have explicit control , you can also manually set the pipeline to use PyTorch's 2.0 efficient attention:
|
||||
|
||||
```py
|
||||
from diffusers.models.attention_processor import AttnAddedKVProcessor2_0
|
||||
|
||||
t2i_pipe.unet.set_attn_processor(AttnAddedKVProcessor2_0())
|
||||
```
|
||||
|
||||
The slowest and most memory intense attention processor is the default `AttnAddedKVProcessor` processor.
|
||||
We do **not** recommend using it except for testing purposes or cases where very high determistic behaviour is desired.
|
||||
You can set it with:
|
||||
|
||||
```py
|
||||
from diffusers.models.attention_processor import AttnAddedKVProcessor
|
||||
|
||||
t2i_pipe.unet.set_attn_processor(AttnAddedKVProcessor())
|
||||
```
|
||||
|
||||
With PyTorch >= 2.0, you can also use Kandinsky with `torch.compile` which depending
|
||||
on your hardware can signficantly speed-up your inference time once the model is compiled.
|
||||
To use Kandinsksy with `torch.compile`, you can do:
|
||||
|
||||
```py
|
||||
t2i_pipe.unet.to(memory_format=torch.channels_last)
|
||||
t2i_pipe.unet = torch.compile(t2i_pipe.unet, mode="reduce-overhead", fullgraph=True)
|
||||
```
|
||||
|
||||
After compilation you should see a very fast inference time. For more information,
|
||||
feel free to have a look at [Our PyTorch 2.0 benchmark](https://huggingface.co/docs/diffusers/main/en/optimization/torch2.0).
|
||||
|
||||
<Tip>
|
||||
|
||||
To generate images directly from a single pipeline, you can use [`KandinskyV22CombinedPipeline`], [`KandinskyV22Img2ImgCombinedPipeline`], [`KandinskyV22InpaintCombinedPipeline`].
|
||||
These combined pipelines wrap the [`KandinskyV22PriorPipeline`] and [`KandinskyV22Pipeline`], [`KandinskyV22Img2ImgPipeline`], [`KandinskyV22InpaintPipeline`] respectively into a single
|
||||
pipeline for a simpler user experience

# Text-to-image model editing
|
||||
|
||||
[Editing Implicit Assumptions in Text-to-Image Diffusion Models](https://huggingface.co/papers/2303.08084) is by Hadas Orgad, Bahjat Kawar, and Yonatan Belinkov. This pipeline enables editing diffusion model weights, such that its assumptions of a given concept are changed. The resulting change is expected to take effect in all prompt generations related to the edited concept.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Text-to-image diffusion models often make implicit assumptions about the world when generating images. While some assumptions are useful (e.g., the sky is blue), they can also be outdated, incorrect, or reflective of social biases present in the training data. Thus, there is a need to control these assumptions without requiring explicit user input or costly re-training. In this work, we aim to edit a given implicit assumption in a pre-trained diffusion model. Our Text-to-Image Model Editing method, TIME for short, receives a pair of inputs: a "source" under-specified prompt for which the model makes an implicit assumption (e.g., "a pack of roses"), and a "destination" prompt that describes the same setting, but with a specified desired attribute (e.g., "a pack of blue roses"). TIME then updates the model's cross-attention layers, as these layers assign visual meaning to textual tokens. We edit the projection matrices in these layers such that the source prompt is projected close to the destination prompt. Our method is highly efficient, as it modifies a mere 2.2% of the model's parameters in under one second. To evaluate model editing approaches, we introduce TIMED (TIME Dataset), containing 147 source and destination prompt pairs from various domains. Our experiments (using Stable Diffusion) show that TIME is successful in model editing, generalizes well for related prompts unseen during editing, and imposes minimal effect on unrelated generations.*

# MusicLDM
|
||||
|
||||
MusicLDM was proposed in [MusicLDM: Enhancing Novelty in Text-to-Music Generation Using Beat-Synchronous Mixup Strategies](https://huggingface.co/papers/2308.01546) by Ke Chen, Yusong Wu, Haohe Liu, Marianna Nezhurina, Taylor Berg-Kirkpatrick, Shlomo Dubnov.
|
||||
MusicLDM takes a text prompt as input and predicts the corresponding music sample.
|
||||
|
||||
Inspired by [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview) and [AudioLDM](https://huggingface.co/docs/diffusers/api/pipelines/audioldm/overview),
|
||||
MusicLDM is a text-to-music _latent diffusion model (LDM)_ that learns continuous audio representations from [CLAP](https://huggingface.co/docs/transformers/main/model_doc/clap)
|
||||
latents.
|
||||
|
||||
MusicLDM is trained on a corpus of 466 hours of music data. Beat-synchronous data augmentation strategies are applied to
|
||||
the music samples, both in the time domain and in the latent space. Using beat-synchronous data augmentation strategies
|
||||
encourages the model to interpolate between the training samples, but stay within the domain of the training data. The
|
||||
result is generated music that is more diverse while staying faithful to the corresponding style.
|
||||
|
||||
The abstract of the paper is the following:
|
||||
|
||||
*In this paper, we present MusicLDM, a state-of-the-art text-to-music model that adapts Stable Diffusion and AudioLDM architectures to the music domain. We achieve this by retraining the contrastive language-audio pretraining model (CLAP) and the Hifi-GAN vocoder, as components of MusicLDM, on a collection of music data samples. Then, we leverage a beat tracking model and propose two different mixup strategies for data augmentation: beat-synchronous audio mixup and beat-synchronous latent mixup, to encourage the model to generate music more diverse while still staying faithful to the corresponding style.*

## Tips
|
||||
|
||||
When constructing a prompt, keep in mind:
|
||||
|
||||
* Descriptive prompt inputs work best; use adjectives to describe the sound (for example, "high quality" or "clear") and make the prompt context specific where possible (e.g. "melodic techno with a fast beat and synths" works better than "techno").
|
||||
* Using a *negative prompt* can significantly improve the quality of the generated audio. Try using a negative prompt of "low quality, average quality".
|
||||
|
||||
During inference:
|
||||
|
||||
* The _quality_ of the generated audio sample can be controlled by the `num_inference_steps` argument; higher steps give higher quality audio at the expense of slower inference.
|
||||
* Multiple waveforms can be generated in one go: set `num_waveforms_per_prompt` to a value greater than 1 to enable. Automatic scoring will be performed between the generated waveforms and prompt text, and the audios ranked from best to worst accordingly.
|
||||
* The _length_ of the generated audio sample can be controlled by varying the `audio_length_in_s` argument.

||||
