# Outpainting
|
||||
|
||||
Outpainting extends an image beyond its original boundaries, allowing you to add, replace, or modify visual elements in an image while preserving the original image. Like [inpainting](../using-diffusers/inpaint), you want to fill the white area (in this case, the area outside of the original image) with new visual elements while keeping the original image (represented by a mask of black pixels). There are a couple of ways to outpaint, such as with a [ControlNet](https://hf.co/blog/OzzyGT/outpainting-controlnet) or with [Differential Diffusion](https://hf.co/blog/OzzyGT/outpainting-differential-diffusion).
|
||||
|
||||
This guide will show you how to outpaint with an inpainting model, ControlNet, and a ZoeDepth estimator.
|
||||
|
||||
Before you begin, make sure you have the [controlnet_aux](https://github.com/huggingface/controlnet_aux) library installed so you can use the ZoeDepth estimator.
|
||||
|
||||
```py
|
||||
!pip install -q controlnet_aux
|
||||
```
|
||||
|
||||
## Image preparation
|
||||
|
||||
Start by picking an image to outpaint with and remove the background with a Space like [BRIA-RMBG-1.4](https://hf.co/spaces/briaai/BRIA-RMBG-1.4).
|
||||
|
||||
<iframe
|
||||
src="https://briaai-bria-rmbg-1-4.hf.space"
|
||||
frameborder="0"
|
||||
width="850"
|
||||
height="450"
|
||||
></iframe>
|
||||
|
||||
For example, remove the background from this image of a pair of shoes.
|
||||
|
||||
<div class="flex flex-row gap-4">
|
||||
<div class="flex-1">
|
||||
<img class="rounded-xl" src="https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/original-jordan.png"/>
|
||||
<figcaption class="mt-2 text-center text-sm text-gray-500">original image</figcaption>
|
||||
</div>
|
||||
<div class="flex-1">
|
||||
<img class="rounded-xl" src="https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/no-background-jordan.png"/>
|
||||
<figcaption class="mt-2 text-center text-sm text-gray-500">background removed</figcaption>
|
||||
</div>
|
||||
</div>
|
||||
|
||||
[Stable Diffusion XL (SDXL)](../using-diffusers/sdxl) models work best with 1024x1024 images, but you can resize the image to any size as long as your hardware has enough memory to support it. The transparent background in the image should also be replaced with a white background. Create a function (like the one below) that scales and pastes the image onto a white background.
|
||||
|
||||
```py
|
||||
import random
|
||||
|
||||
import requests
|
||||
import torch
|
||||

||||
AutoencoderKL,
|
||||
ControlNetModel,
|
||||
StableDiffusionXLControlNetPipeline,
|
||||
StableDiffusionXLInpaintPipeline,
|
||||
)
|
||||
|
||||
def scale_and_paste(original_image):
|
||||
aspect_ratio = original_image.width / original_image.height
|
||||
|
||||
if original_image.width > original_image.height:
|
||||
new_width = 1024
|
||||
new_height = round(new_width / aspect_ratio)
|
||||
else:
|
||||
new_height = 1024
|
||||
new_width = round(new_height * aspect_ratio)
|
||||
|
||||
resized_original = original_image.resize((new_width, new_height), Image.LANCZOS)
|
||||
white_background = Image.new("RGBA", (1024, 1024), "white")
|
||||
x = (1024 - new_width) // 2
|
||||
y = (1024 - new_height) // 2
|
||||
white_background.paste(resized_original, (x, y), resized_original)
|
||||
|
||||
return resized_original, white_background
|
||||
|
||||
original_image = Image.open(
|
||||
requests.get(
|
||||
"https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/no-background-jordan.png",
|
||||
stream=True,
|
||||
).raw
|
||||
).convert("RGBA")
|
||||
resized_img, white_bg_image = scale_and_paste(original_image)
|
||||
```

||||
To avoid adding unwanted extra details, use the ZoeDepth estimator to provide additional guidance during generation and to ensure the shoes remain consistent with the original image.
|
||||
|
||||
```py
|
||||
zoe = ZoeDetector.from_pretrained("lllyasviel/Annotators")
|
||||
image_zoe = zoe(white_bg_image, detect_resolution=512, image_resolution=1024)
|
||||
image_zoe
|
||||
```
|
||||
|
||||
<div class="flex justify-center">
|
||||
<img src="https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/zoedepth-jordan.png"/>
|
||||
</div>
|
||||
|
||||
## Outpaint
|
||||
|
||||
Once your image is ready, you can generate content in the white area around the shoes with [controlnet-inpaint-dreamer-sdxl](https://hf.co/destitech/controlnet-inpaint-dreamer-sdxl), a SDXL ControlNet trained for inpainting.
|
||||
|
||||
Load the inpainting ControlNet, ZoeDepth model, VAE and pass them to the [`StableDiffusionXLControlNetPipeline`]. Then you can create an optional `generate_image` function (for convenience) to outpaint an initial image.
|
||||
|
||||
```py
|
||||
controlnets = [
|
||||
ControlNetModel.from_pretrained(
|
||||
"destitech/controlnet-inpaint-dreamer-sdxl", torch_dtype=torch.float16, variant="fp16"
|
||||
),
|
||||
ControlNetModel.from_pretrained(
|
||||
"diffusers/controlnet-zoe-depth-sdxl-1.0", torch_dtype=torch.float16
|
||||
),
|
||||
]
|
||||
vae = AutoencoderKL.from_pretrained("madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16).to("cuda")
|
||||
pipeline = StableDiffusionXLControlNetPipeline.from_pretrained(
|
||||
"SG161222/RealVisXL_V4.0", torch_dtype=torch.float16, variant="fp16", controlnet=controlnets, vae=vae
|
||||
).to("cuda")
|
||||
|
||||
def generate_image(prompt, negative_prompt, inpaint_image, zoe_image, seed: int = None):
|
||||
if seed is None:
|
||||
seed = random.randint(0, 2**32 - 1)
|
||||
|
||||
generator = torch.Generator(device="cpu").manual_seed(seed)
|
||||
|
||||
image = pipeline(
|
||||
prompt,
|
||||
negative_prompt=negative_prompt,
|
||||
image=[inpaint_image, zoe_image],
|
||||
guidance_scale=6.5,
|
||||
num_inference_steps=25,
|
||||
generator=generator,
|
||||
controlnet_conditioning_scale=[0.5, 0.8],
|
||||
control_guidance_end=[0.9, 0.6],
|
||||
).images[0]
|
||||
|
||||
return image
|
||||
|
||||
prompt = "nike air jordans on a basketball court"
|
||||
negative_prompt = ""
|
||||
|
||||
temp_image = generate_image(prompt, negative_prompt, white_bg_image, image_zoe, 908097)
|
||||
```
|
||||
|
||||
Paste the original image over the initial outpainted image. You'll improve the outpainted background in a later step.
|
||||
|
||||
```py
|
||||
x = (1024 - resized_img.width) // 2
|
||||
y = (1024 - resized_img.height) // 2
|
||||
temp_image.paste(resized_img, (x, y), resized_img)
|
||||
temp_image
|
||||
```
|
||||
|
||||
<div class="flex justify-center">
|
||||
<img src="https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/initial-outpaint.png"/>
|
||||
</div>
|
||||
|
||||
> [!TIP]
|
||||
> Now is a good time to free up some memory if you're running low!
|
||||
>
|
||||
> ```py
|
||||
> pipeline=None
|
||||
> torch.cuda.empty_cache()
|
||||
> ```
|
||||
|
||||
Now that you have an initial outpainted image, load the [`StableDiffusionXLInpaintPipeline`] with the [RealVisXL](https://hf.co/SG161222/RealVisXL_V4.0) model to generate the final outpainted image with better quality.
|
||||
|
||||
```py
|
||||
pipeline = StableDiffusionXLInpaintPipeline.from_pretrained(
|
||||
"OzzyGT/RealVisXL_V4.0_inpainting",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
vae=vae,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Prepare a mask for the final outpainted image. To create a more natural transition between the original image and the outpainted background, blur the mask to help it blend better.
|
||||
|
||||
```py
|
||||
mask = Image.new("L", temp_image.size)
|
||||
mask.paste(resized_img.split()[3], (x, y))
|
||||
mask = ImageOps.invert(mask)
|
||||
final_mask = mask.point(lambda p: p > 128 and 255)
|
||||
mask_blurred = pipeline.mask_processor.blur(final_mask, blur_factor=20)
|
||||
mask_blurred
|
||||
```
|
||||
|
||||
<div class="flex justify-center">
|
||||
<img src="https://huggingface.co/datasets/stevhliu/testing-images/resolve/main/blurred-mask.png"/>
|
||||
</div>
|
||||
|
||||
Create a better prompt and pass it to the `generate_outpaint` function to generate the final outpainted image. Again, paste the original image over the final outpainted background.
|
||||
|
||||
```py
|
||||
def generate_outpaint(prompt, negative_prompt, image, mask, seed: int = None):
|
||||
if seed is None:
|
||||
seed = random.randint(0, 2**32 - 1)

# Single files
|
||||
|
||||
Diffusers supports loading pretrained pipeline (or model) weights stored in a single file, such as a `ckpt` or `safetensors` file. These single file types are typically produced from community trained models. There are three classes for loading single file weights:
|
||||
The [`~loaders.FromSingleFileMixin.from_single_file`] method allows you to load:
|
||||
|
||||
- [`FromSingleFileMixin`] supports loading pretrained pipeline weights stored in a single file, which can either be a `ckpt` or `safetensors` file.
|
||||
- [`FromOriginalVAEMixin`] supports loading a pretrained [`AutoencoderKL`] from pretrained ControlNet weights stored in a single file, which can either be a `ckpt` or `safetensors` file.
|
||||
- [`FromOriginalControlnetMixin`] supports loading pretrained ControlNet weights stored in a single file, which can either be a `ckpt` or `safetensors` file.
|
||||
* a model stored in a single file, which is useful if you're working with models from the diffusion ecosystem, like Automatic1111, and commonly rely on a single-file layout to store and share models
|
||||
* a model stored in their originally distributed layout, which is useful if you're working with models finetuned with other services, and want to load it directly into Diffusers model objects and pipelines
|
||||

||||

||||
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]
|
||||
```

# Hunyuan-DiT
|
||||

|
||||
|
||||
[Hunyuan-DiT : A Powerful Multi-Resolution Diffusion Transformer with Fine-Grained Chinese Understanding](https://arxiv.org/abs/2405.08748) from Tencent Hunyuan.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*We present Hunyuan-DiT, a text-to-image diffusion transformer with fine-grained understanding of both English and Chinese. To construct Hunyuan-DiT, we carefully design the transformer structure, text encoder, and positional encoding. We also build from scratch a whole data pipeline to update and evaluate data for iterative model optimization. For fine-grained language understanding, we train a Multimodal Large Language Model to refine the captions of the images. Finally, Hunyuan-DiT can perform multi-turn multimodal dialogue with users, generating and refining images according to the context. Through our holistic human evaluation protocol with more than 50 professional human evaluators, Hunyuan-DiT sets a new state-of-the-art in Chinese-to-image generation compared with other open-source models.*
|
||||
|
||||
|
||||
You can find the original codebase at [Tencent/HunyuanDiT](https://github.com/Tencent/HunyuanDiT) and all the available checkpoints at [Tencent-Hunyuan](https://huggingface.co/Tencent-Hunyuan/HunyuanDiT).
|
||||
|
||||
**Highlights**: HunyuanDiT supports Chinese/English-to-image, multi-resolution generation.
|
||||
|
||||
HunyuanDiT has the following components:
|
||||
* It uses a diffusion transformer as the backbone
|
||||
* It combines two text encoders, a bilingual CLIP and a multilingual T5 encoder
|
||||

|
||||
|
||||
</Tip>
|
||||
|
||||
## Optimization
|
||||
|
||||
You can optimize the pipeline's runtime and memory consumption with torch.compile and feed-forward chunking. To learn about other optimization methods, check out the [Speed up inference](../../optimization/fp16) and [Reduce memory usage](../../optimization/memory) guides.
|
||||
|
||||
### Inference
|
||||
|
||||
Use [`torch.compile`](https://huggingface.co/docs/diffusers/main/en/tutorials/fast_diffusion#torchcompile) to reduce the inference latency.
|
||||
|
||||
First, load the pipeline:
|
||||
|
||||
```python
|
||||
from diffusers import HunyuanDiTPipeline
|
||||
import torch
|
||||
|
||||
pipeline = HunyuanDiTPipeline.from_pretrained(
|
||||
"Tencent-Hunyuan/HunyuanDiT-Diffusers", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Then change the memory layout of the pipelines `transformer` and `vae` components to `torch.channels-last`:
|
||||
|
||||
```python
|
||||
pipeline.transformer.to(memory_format=torch.channels_last)
|
||||
pipeline.vae.to(memory_format=torch.channels_last)
|
||||
```
|
||||
|
||||
Finally, compile the components and run inference:
|
||||
|
||||
```python
|
||||
pipeline.transformer = torch.compile(pipeline.transformer, mode="max-autotune", fullgraph=True)
|
||||
pipeline.vae.decode = torch.compile(pipeline.vae.decode, mode="max-autotune", fullgraph=True)
|
||||
|
||||
image = pipeline(prompt="一个宇航员在骑马").images[0]
|
||||
```
|
||||
|
||||
The [benchmark](https://gist.github.com/sayakpaul/29d3a14905cfcbf611fe71ebd22e9b23) results on a 80GB A100 machine are:
|
||||
|
||||
```bash
|
||||
With torch.compile(): Average inference time: 12.470 seconds.
|
||||
Without torch.compile(): Average inference time: 20.570 seconds.
|
||||
```
|
||||
|
||||
### Memory optimization
|
||||
|
||||
By loading the T5 text encoder in 8 bits, you can run the pipeline in just under 6 GBs of GPU VRAM. Refer to [this script](https://gist.github.com/sayakpaul/3154605f6af05b98a41081aaba5ca43e) for details.
|
||||
|
||||
Furthermore, you can use the [`~HunyuanDiT2DModel.enable_forward_chunking`] method to reduce memory usage. Feed-forward chunking runs the feed-forward layers in a transformer block in a loop instead of all at once. This gives you a trade-off between memory consumption and inference runtime.
|
||||
|
||||
```diff
|
||||
+ pipeline.transformer.enable_forward_chunking(chunk_size=1, dim=1)
|
||||
```

# Marigold Pipelines for Computer Vision Tasks
|
||||
|
||||

|
||||
|
||||
Marigold was proposed in [Repurposing Diffusion-Based Image Generators for Monocular Depth Estimation](https://huggingface.co/papers/2312.02145), a CVPR 2024 Oral paper by [Bingxin Ke](http://www.kebingxin.com/), [Anton Obukhov](https://www.obukhov.ai/), [Shengyu Huang](https://shengyuh.github.io/), [Nando Metzger](https://nandometzger.github.io/), [Rodrigo Caye Daudt](https://rcdaudt.github.io/), and [Konrad Schindler](https://scholar.google.com/citations?user=FZuNgqIAAAAJ&hl=en).
|
||||
The idea is to repurpose the rich generative prior of Text-to-Image Latent Diffusion Models (LDMs) for traditional computer vision tasks.
|
||||
Initially, this idea was explored to fine-tune Stable Diffusion for Monocular Depth Estimation, as shown in the teaser above.
|
||||
Later,
|
||||
- [Tianfu Wang](https://tianfwang.github.io/) trained the first Latent Consistency Model (LCM) of Marigold, which unlocked fast single-step inference;
|
||||
- [Kevin Qu](https://www.linkedin.com/in/kevin-qu-b3417621b/?locale=en_US) extended the approach to Surface Normals Estimation;
|
||||
- [Anton Obukhov](https://www.obukhov.ai/) contributed the pipelines and documentation into diffusers (enabled and supported by [YiYi Xu](https://yiyixuxu.github.io/) and [Sayak Paul](https://sayak.dev/)).
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*Monocular depth estimation is a fundamental computer vision task. Recovering 3D depth from a single image is geometrically ill-posed and requires scene understanding, so it is not surprising that the rise of deep learning has led to a breakthrough. The impressive progress of monocular depth estimators has mirrored the growth in model capacity, from relatively modest CNNs to large Transformer architectures. Still, monocular depth estimators tend to struggle when presented with images with unfamiliar content and layout, since their knowledge of the visual world is restricted by the data seen during training, and challenged by zero-shot generalization to new domains. This motivates us to explore whether the extensive priors captured in recent generative diffusion models can enable better, more generalizable depth estimation. We introduce Marigold, a method for affine-invariant monocular depth estimation that is derived from Stable Diffusion and retains its rich prior knowledge. The estimator can be fine-tuned in a couple of days on a single GPU using only synthetic training data. It delivers state-of-the-art performance across a wide range of datasets, including over 20% performance gains in specific cases. Project page: https://marigoldmonodepth.github.io.*

|
||||
## Available Pipelines
|
||||
|
||||
Each pipeline supports one Computer Vision task, which takes an input RGB image as input and produces a *prediction* of the modality of interest, such as a depth map of the input image.
|
||||
Currently, the following tasks are implemented:

<Tip warning={true}>
|
||||
|
||||
Marigold pipelines were designed and tested only with `DDIMScheduler` and `LCMScheduler`.
|
||||
Depending on the scheduler, the number of inference steps required to get reliable predictions varies, and there is no universal value that works best across schedulers.
|
||||
Because of that, the default value of `num_inference_steps` in the `__call__` method of the pipeline is set to `None` (see the API reference).
|
||||
Unless set explicitly, its value will be taken from the checkpoint configuration `model_index.json`.
|
||||
This is done to ensure high-quality predictions when calling the pipeline with just the `image` argument.

# PixArt-Σ
|
||||
|
||||

|
||||
|
||||
[PixArt-Σ: Weak-to-Strong Training of Diffusion Transformer for 4K Text-to-Image Generation](https://huggingface.co/papers/2403.04692) is Junsong Chen, Jincheng Yu, Chongjian Ge, Lewei Yao, Enze Xie, Yue Wu, Zhongdao Wang, James Kwok, Ping Luo, Huchuan Lu, and Zhenguo Li.
|
||||
|
||||
The abstract from the paper is:
|
||||
|
||||
*In this paper, we introduce PixArt-Σ, a Diffusion Transformer model (DiT) capable of directly generating images at 4K resolution. PixArt-Σ represents a significant advancement over its predecessor, PixArt-α, offering images of markedly higher fidelity and improved alignment with text prompts. A key feature of PixArt-Σ is its training efficiency. Leveraging the foundational pre-training of PixArt-α, it evolves from the ‘weaker’ baseline to a ‘stronger’ model via incorporating higher quality data, a process we term “weak-to-strong training”. The advancements in PixArt-Σ are twofold: (1) High-Quality Training Data: PixArt-Σ incorporates superior-quality image data, paired with more precise and detailed image captions. (2) Efficient Token Compression: we propose a novel attention module within the DiT framework that compresses both keys and values, significantly improving efficiency and facilitating ultra-high-resolution image generation. Thanks to these improvements, PixArt-Σ achieves superior image quality and user prompt adherence capabilities with significantly smaller model size (0.6B parameters) than existing text-to-image diffusion models, such as SDXL (2.6B parameters) and SD Cascade (5.1B parameters). Moreover, PixArt-Σ’s capability to generate 4K images supports the creation of high-resolution posters and wallpapers, efficiently bolstering the production of highquality visual content in industries such as film and gaming.*
|
||||
|
||||
You can find the original codebase at [PixArt-alpha/PixArt-sigma](https://github.com/PixArt-alpha/PixArt-sigma) and all the available checkpoints at [PixArt-alpha](https://huggingface.co/PixArt-alpha).
|
||||
|
||||
Some notes about this pipeline:
|
||||
|
||||
* It uses a Transformer backbone (instead of a UNet) for denoising. As such it has a similar architecture as [DiT](https://hf.co/docs/transformers/model_doc/dit).
|
||||
* It was trained using text conditions computed from T5. This aspect makes the pipeline better at following complex text prompts with intricate details.
|
||||
* It is good at producing high-resolution images at different aspect ratios. To get the best results, the authors recommend some size brackets which can be found [here](https://github.com/PixArt-alpha/PixArt-sigma/blob/master/diffusion/data/datasets/utils.py).
|
||||
* It rivals the quality of state-of-the-art text-to-image generation systems (as of this writing) such as PixArt-α, Stable Diffusion XL, Playground V2.0 and DALL-E 3, while being more efficient than them.
|
||||
* It shows the ability of generating super high resolution images, such as 2048px or even 4K.
|
||||
* It shows that text-to-image models can grow from a weak model to a stronger one through several improvements (VAEs, datasets, and so on.)

|

## Inference with under 8GB GPU VRAM
|
||||
|
||||
Run the [`PixArtSigmaPipeline`] with under 8GB GPU VRAM by loading the text encoder in 8-bit precision. Let's walk through a full-fledged example.
|
||||
|
||||
First, install the [bitsandbytes](https://github.com/TimDettmers/bitsandbytes) library:
|
||||
|
||||
```bash
|
||||
pip install -U bitsandbytes
|
||||
```
|
||||
|
||||
Then load the text encoder in 8-bit:
|
||||
|
||||
```python
|
||||
from transformers import T5EncoderModel
|
||||
from diffusers import PixArtSigmaPipeline
|
||||
import torch
|
||||
|
||||
text_encoder = T5EncoderModel.from_pretrained(
|
||||
"PixArt-alpha/PixArt-Sigma-XL-2-1024-MS",
|
||||
subfolder="text_encoder",
|
||||
load_in_8bit=True,
|
||||
device_map="auto",
|
||||
)
|
||||
pipe = PixArtSigmaPipeline.from_pretrained(
|
||||
"PixArt-alpha/PixArt-Sigma-XL-2-1024-MS",
|
||||
text_encoder=text_encoder,
|
||||
transformer=None,
|
||||
device_map="balanced"
|
||||
)
|
||||
```
|
||||
|
||||
Now, use the `pipe` to encode a prompt:
|
||||
|
||||
```python
|
||||
with torch.no_grad():
|
||||
prompt = "cute cat"
|
||||
prompt_embeds, prompt_attention_mask, negative_embeds, negative_prompt_attention_mask = pipe.encode_prompt(prompt)
|
||||
```
|
||||
|
||||
Since text embeddings have been computed, remove the `text_encoder` and `pipe` from the memory, and free up some GPU VRAM:
|
||||
|
||||
```python
|
||||
import gc
|
||||
|
||||
def flush():
|
||||
gc.collect()
|
||||
torch.cuda.empty_cache()
|
||||
|
||||
del text_encoder
|
||||
del pipe
|
||||
flush()
|
||||
```
|
||||
|
||||
Then compute the latents with the prompt embeddings as inputs:
|
||||
|
||||
```python
|
||||
pipe = PixArtSigmaPipeline.from_pretrained(
|
||||
"PixArt-alpha/PixArt-Sigma-XL-2-1024-MS",
|
||||
text_encoder=None,
|
||||
torch_dtype=torch.float16,
|
||||
).to("cuda")
|
||||
|
||||
latents = pipe(
|
||||
negative_prompt=None,
|
||||
prompt_embeds=prompt_embeds,
|
||||
negative_prompt_embeds=negative_embeds,
|
||||
prompt_attention_mask=prompt_attention_mask,
|
||||
negative_prompt_attention_mask=negative_prompt_attention_mask,
|
||||
num_images_per_prompt=1,
|
||||
output_type="latent",
|
||||
).images
|
||||
|
||||
del pipe.transformer
|
||||
flush()
|
||||
```
|
||||
|
||||
<Tip>
|
||||
|
||||
Notice that while initializing `pipe`, you're setting `text_encoder` to `None` so that it's not loaded.
|
||||
|
||||
</Tip>
|
||||
|
||||
Once the latents are computed, pass it off to the VAE to decode into a real image:
|
||||
|
||||
```python
|
||||
with torch.no_grad():
|
||||
image = pipe.vae.decode(latents / pipe.vae.config.scaling_factor, return_dict=False)[0]
|
||||
image = pipe.image_processor.postprocess(image, output_type="pil")[0]
|
||||
image.save("cat.png")
|
||||
```
|
||||
|
||||
By deleting components you aren't using and flushing the GPU VRAM, you should be able to run [`PixArtSigmaPipeline`] with under 8GB GPU VRAM.
|
||||
|
||||

|
||||
|
||||
If you want a report of your memory-usage, run this [script](https://gist.github.com/sayakpaul/3ae0f847001d342af27018a96f467e4e).
|
||||
|
||||
<Tip warning={true}>
|
||||
|
||||
Text embeddings computed in 8-bit can impact the quality of the generated images because of the information loss in the representation space caused by the reduced precision. It's recommended to compare the outputs with and without 8-bit.
|
||||
|
||||
</Tip>
|
||||
|
||||
While loading the `text_encoder`, you set `load_in_8bit` to `True`. You could also specify `load_in_4bit` to bring your memory requirements down even further to under 7GB.

## Usage example with the base model of StableDiffusion-1.4/1.5
|
||||
|
||||
In the following we give a simple example of how to use a *T2I-Adapter* checkpoint with Diffusers for inference based on StableDiffusion-1.4/1.5.
|
||||
All adapters use the same pipeline.
|
||||
|
||||
1. Images are first converted into the appropriate *control image* format.
|
||||
2. The *control image* and *prompt* are passed to the [`StableDiffusionAdapterPipeline`].
|
||||
|
||||
Let's have a look at a simple example using the [Color Adapter](https://huggingface.co/TencentARC/t2iadapter_color_sd14v1).
|
||||
|
||||
```python
|
||||
from diffusers.utils import load_image, make_image_grid
|
||||
|
||||
image = load_image("https://huggingface.co/datasets/diffusers/docs-images/resolve/main/t2i-adapter/color_ref.png")
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
Then we can create our color palette by simply resizing it to 8 by 8 pixels and then scaling it back to original size.
|
||||
|
||||
```python
|
||||
from PIL import Image
|
||||
|
||||
color_palette = image.resize((8, 8))
|
||||
color_palette = color_palette.resize((512, 512), resample=Image.Resampling.NEAREST)
|
||||
```
|
||||
|
||||
Let's take a look at the processed image.
|
||||
|
||||

|
||||
|
||||
|
||||
Next, create the adapter pipeline
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import StableDiffusionAdapterPipeline, T2IAdapter
|
||||
|
||||
adapter = T2IAdapter.from_pretrained("TencentARC/t2iadapter_color_sd14v1", torch_dtype=torch.float16)
|
||||
pipe = StableDiffusionAdapterPipeline.from_pretrained(
|
||||
"CompVis/stable-diffusion-v1-4",
|
||||
adapter=adapter,
|
||||
torch_dtype=torch.float16,
|
||||
)
|
||||
pipe.to("cuda")
|
||||
```
|
||||
|
||||
Finally, pass the prompt and control image to the pipeline
|
||||
|
||||
```py
|
||||
# fix the random seed, so you will get the same result as the example
|
||||
generator = torch.Generator("cuda").manual_seed(7)
|
||||
|
||||
out_image = pipe(
|
||||
"At night, glowing cubes in front of the beach",
|
||||
image=color_palette,
|
||||
generator=generator,
|
||||
).images[0]
|
||||
make_image_grid([image, color_palette, out_image], rows=1, cols=3)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Usage example with the base model of StableDiffusion-XL
|
||||
|
||||
In the following we give a simple example of how to use a *T2I-Adapter* checkpoint with Diffusers for inference based on StableDiffusion-XL.
|
||||
All adapters use the same pipeline.
|
||||
|
||||
1. Images are first downloaded into the appropriate *control image* format.
|
||||
2. The *control image* and *prompt* are passed to the [`StableDiffusionXLAdapterPipeline`].
|
||||
|
||||
Let's have a look at a simple example using the [Sketch Adapter](https://huggingface.co/Adapter/t2iadapter/tree/main/sketch_sdxl_1.0).
|
||||
|
||||
```python
|
||||
from diffusers.utils import load_image, make_image_grid
|
||||
|
||||
sketch_image = load_image("https://huggingface.co/Adapter/t2iadapter/resolve/main/sketch.png").convert("L")
|
||||
```
|
||||
|
||||

|
||||
|
||||
Then, create the adapter pipeline
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import (
|
||||
T2IAdapter,
|
||||
StableDiffusionXLAdapterPipeline,
|
||||

|
||||

|
||||
|
||||
model_id = "stabilityai/stable-diffusion-xl-base-1.0"

||||
adapter = T2IAdapter.from_pretrained("Adapter/t2iadapter", subfolder="sketch_sdxl_1.0", torch_dtype=torch.float16, adapter_type="full_adapter_xl")
|
||||

|
||||
)

||||

Finally, pass the prompt and control image to the pipeline

## Combining multiple adapters
|
||||
|
||||
[`MultiAdapter`] can be used for applying multiple conditionings at once.
|
||||
|
||||
Here we use the keypose adapter for the character posture and the depth adapter for creating the scene.
|
||||
|
||||
```py
|
||||
from diffusers.utils import load_image, make_image_grid
|
||||
|
||||
cond_keypose = load_image(
|
||||
"https://huggingface.co/datasets/diffusers/docs-images/resolve/main/t2i-adapter/keypose_sample_input.png"
|
||||
)
|
||||
cond_depth = load_image(
|
||||
"https://huggingface.co/datasets/diffusers/docs-images/resolve/main/t2i-adapter/depth_sample_input.png"
|
||||
)
|
||||
cond = [cond_keypose, cond_depth]
|
||||
|
||||
prompt = ["A man walking in an office room with a nice view"]
|
||||
```
|
||||
|
||||
The two control images look as such:
|
||||
|
||||

|
||||

|
||||
|
||||
|
||||
`MultiAdapter` combines keypose and depth adapters.
|
||||
|
||||
`adapter_conditioning_scale` balances the relative influence of the different adapters.
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import StableDiffusionAdapterPipeline, MultiAdapter, T2IAdapter
|
||||
|
||||
adapters = MultiAdapter(
|
||||
[
|
||||
T2IAdapter.from_pretrained("TencentARC/t2iadapter_keypose_sd14v1"),
|
||||
T2IAdapter.from_pretrained("TencentARC/t2iadapter_depth_sd14v1"),
|
||||
]
|
||||
)
|
||||
adapters = adapters.to(torch.float16)
|
||||
|
||||
pipe = StableDiffusionAdapterPipeline.from_pretrained(
|
||||
"CompVis/stable-diffusion-v1-4",
|
||||
torch_dtype=torch.float16,
|
||||
adapter=adapters,
|
||||
).to("cuda")
|
||||
|
||||
image = pipe(prompt, cond, adapter_conditioning_scale=[0.8, 0.8]).images[0]
|
||||
make_image_grid([cond_keypose, cond_depth, image], rows=1, cols=3)
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
## T2I-Adapter vs ControlNet
|
||||
|
||||
T2I-Adapter is similar to [ControlNet](https://huggingface.co/docs/diffusers/main/en/api/pipelines/controlnet).
|
||||
T2I-Adapter uses a smaller auxiliary network which is only run once for the entire diffusion process.
|
||||
However, T2I-Adapter performs slightly worse than ControlNet.

### 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/overview) and [schedulers](https://huggingface.co/docs/diffusers/api/schedulers/overview).
|
||||
We support two types of pipelines:
|
||||
> [!TIP]
|
||||
> Read the [Community pipelines](../using-diffusers/custom_pipeline_overview#community-pipelines) guide to learn more about the difference between a GitHub and Hugging Face Hub community pipeline. If you're interested in why we have community pipelines, take a look at GitHub Issue [#841](https://github.com/huggingface/diffusers/issues/841) (basically, we can't maintain all the possible ways diffusion models can be used for inference but we also don't want to prevent the community from building them).
|
||||
|
||||
- Official Pipelines
|
||||
- Community Pipelines
|
||||
Contributing a community pipeline is a great way to share your creativity and work with the community. It lets you build on top of the [`DiffusionPipeline`] so that anyone can load and use it by setting the `custom_pipeline` parameter. This section will walk you through how to create a simple pipeline where the UNet only does a single forward pass and calls the scheduler once (a "one-step" pipeline).
|
||||
|
||||
Both official and community pipelines follow the same design and consist of the same type of components.
|
||||
1. Create a one_step_unet.py file for your community pipeline. This file can contain whatever package you want to use as long as it's installed by the user. Make sure you only have one pipeline class that inherits from [`DiffusionPipeline`] to load model weights and the scheduler configuration from the Hub. Add a UNet and scheduler to the `__init__` function.
|
||||
|
||||
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.
|
||||
You should also add the `register_modules` function to ensure your pipeline and its components can be saved with [`~DiffusionPipeline.save_pretrained`].
|
||||
|
||||
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.
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
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.
|
||||
class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
|
||||
def __init__(self, unet, scheduler):
|
||||
super().__init__()
|
||||
|
||||
An example can be seen [here](https://github.com/huggingface/diffusers/pull/2400).
|
||||
self.register_modules(unet=unet, scheduler=scheduler)
|
||||
```
|
||||
|
||||
Community pipeline PRs are only checked at a superficial level and ideally they should be maintained by their original authors.
|
||||
1. In the forward pass (which we recommend defining as `__call__`), you can add any feature you'd like. For the "one-step" pipeline, create a random image and call the UNet and scheduler once by setting `timestep=1`.
|
||||
|
||||
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.
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
|
||||
def __init__(self, unet, scheduler):
|
||||
super().__init__()
|
||||
|
||||
self.register_modules(unet=unet, scheduler=scheduler)
|
||||
|
||||
def __call__(self):
|
||||
image = torch.randn(
|
||||
(1, self.unet.config.in_channels, self.unet.config.sample_size, self.unet.config.sample_size),
|
||||
)
|
||||
timestep = 1
|
||||
|
||||
model_output = self.unet(image, timestep).sample
|
||||
scheduler_output = self.scheduler.step(model_output, timestep, image).prev_sample
|
||||
|
||||
return scheduler_output
|
||||
```
|
||||
|
||||
Now you can run the pipeline by passing a UNet and scheduler to it or load pretrained weights if the pipeline structure is identical.
|
||||
|
||||
```py
|
||||
from diffusers import DDPMScheduler, UNet2DModel
|
||||
|
||||
scheduler = DDPMScheduler()
|
||||
unet = UNet2DModel()
|
||||
|
||||
pipeline = UnetSchedulerOneForwardPipeline(unet=unet, scheduler=scheduler)
|
||||
output = pipeline()
|
||||
# load pretrained weights
|
||||
pipeline = UnetSchedulerOneForwardPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
|
||||
output = pipeline()
|
||||
```
|
||||
|
||||
You can either share your pipeline as a GitHub community pipeline or Hub community pipeline.

||||

||||

# Speed up inference
|
||||
|
||||
There are several ways to optimize 🤗 Diffusers for inference speed. As a general rule of thumb, we recommend using either [xFormers](xformers) or `torch.nn.functional.scaled_dot_product_attention` in PyTorch 2.0 for their memory-efficient attention.
|
||||
There are several ways to optimize Diffusers for inference speed, such as reducing the computational burden by lowering the data precision or using a lightweight distilled model. There are also memory-efficient attention implementations, [xFormers](xformers) and [scaled dot product attention](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html) in PyTorch 2.0, that reduce memory usage which also indirectly speeds up inference. Different speed optimizations can be stacked together to get the fastest inference times.
|
||||

## Use TensorFloat-32
|
||||
|
||||
On Ampere and later CUDA devices, matrix multiplications and convolutions can use the [TensorFloat-32 (TF32)](https://blogs.nvidia.com/blog/2020/05/14/tensorfloat-32-precision-format/) mode for faster, but slightly less accurate computations. By default, PyTorch enables TF32 mode for convolutions but not matrix multiplications. Unless your network requires full float32 precision, we recommend enabling TF32 for matrix multiplications. It can significantly speeds up computations with typically negligible loss in numerical accuracy.

## Distilled model
|
||||
|
||||
You could also use a distilled Stable Diffusion model and autoencoder to speed up inference. During distillation, many of the UNet's residual and attention blocks are shed to reduce the model size. The distilled model is faster and uses less memory while generating images of comparable quality to the full Stable Diffusion model.

# Overview
|
||||
|
||||
Generating high-quality outputs is computationally intensive, especially during each iterative step where you go from a noisy output to a less noisy output. One of 🤗 Diffuser's goals is to make this technology widely accessible to everyone, which includes enabling fast inference on consumer and specialized hardware.
|
||||
|
||||
This section will cover tips and tricks - like half-precision weights and sliced attention - for optimizing inference speed and reducing memory-consumption. You'll also learn how to speed up your PyTorch code with [`torch.compile`](https://pytorch.org/tutorials/intermediate/torch_compile_tutorial.html) or [ONNX Runtime](https://onnxruntime.ai/docs/), and enable memory-efficient attention with [xFormers](https://facebookresearch.github.io/xformers/). There are also guides for running inference on specific hardware like Apple Silicon, and Intel or Habana processors.

# T-GATE
|
||||
|
||||
[T-GATE](https://github.com/HaozheLiu-ST/T-GATE/tree/main) accelerates inference for [Stable Diffusion](../api/pipelines/stable_diffusion/overview), [PixArt](../api/pipelines/pixart), and [Latency Consistency Model](../api/pipelines/latent_consistency_models.md) pipelines by skipping the cross-attention calculation once it converges. This method doesn't require any additional training and it can speed up inference from 10-50%. T-GATE is also compatible with other optimization methods like [DeepCache](./deepcache).
|
||||
|
||||
Before you begin, make sure you install T-GATE.
|
||||
|
||||
```bash
|
||||
pip install tgate
|
||||
pip install -U torch diffusers transformers accelerate DeepCache
|
||||
```
|
||||
|
||||
|
||||
To use T-GATE with a pipeline, you need to use its corresponding loader.
|
||||
|
||||
| Pipeline | T-GATE Loader |
|
||||
|---|---|
|
||||
| PixArt | TgatePixArtLoader |
|
||||
| Stable Diffusion XL | TgateSDXLLoader |
|
||||
| Stable Diffusion XL + DeepCache | TgateSDXLDeepCacheLoader |
|
||||
| Stable Diffusion | TgateSDLoader |
|
||||
| Stable Diffusion + DeepCache | TgateSDDeepCacheLoader |
|
||||
|
||||
Next, create a `TgateLoader` with a pipeline, the gate step (the time step to stop calculating the cross attention), and the number of inference steps. Then call the `tgate` method on the pipeline with a prompt, gate step, and the number of inference steps.
|
||||
|
||||

### Device placement
|
||||
|
||||
> [!WARNING]
|
||||
> This feature is experimental and its APIs might change in the future.
|
||||
|
||||
With Accelerate, you can use the `device_map` to determine how to distribute the models of a pipeline across multiple devices. This is useful in situations where you have more than one GPU.
|
||||
|
||||
For example, if you have two 8GB GPUs, then using [`~DiffusionPipeline.enable_model_cpu_offload`] may not work so well because:
|
||||
|
||||
* it only works on a single GPU
|
||||
* a single model might not fit on a single GPU ([`~DiffusionPipeline.enable_sequential_cpu_offload`] might work but it will be extremely slow and it is also limited to a single GPU)
|
||||
|
||||
To make use of both GPUs, you can use the "balanced" device placement strategy which splits the models across all available GPUs.
|
||||
|
||||
> [!WARNING]
|
||||
> Only the "balanced" strategy is supported at the moment, and we plan to support additional mapping strategies in the future.

If a device is not present in `max_memory`, then it will be completely ignored and will not participate in the device placement.
|
||||
|
||||
By default, Diffusers uses the maximum memory of all devices. If the models don't fit on the GPUs, they are offloaded to the CPU. If the CPU doesn't have enough memory, then you might see an error. In that case, you could defer to using [`~DiffusionPipeline.enable_sequential_cpu_offload`] and [`~DiffusionPipeline.enable_model_cpu_offload`].
|
||||
|
||||
Call [`~DiffusionPipeline.reset_device_map`] to reset the `device_map` of a pipeline. This is also necessary if you want to use methods like `to()`, [`~DiffusionPipeline.enable_sequential_cpu_offload`], and [`~DiffusionPipeline.enable_model_cpu_offload`] on a pipeline that was device-mapped.
|
||||
|
||||
```py
|
||||
pipeline.reset_device_map()
|
||||
```
|
||||
|
||||
Once a pipeline has been device-mapped, you can also access its device map via `hf_device_map`:
|
||||
|
||||
```py
|
||||
print(pipeline.hf_device_map)
|
||||
```
|
||||
|
||||
An example device map would look like so:
|
||||
|
||||
|
||||
```bash
|
||||
{'unet': 1, 'vae': 1, 'safety_checker': 0, 'text_encoder': 0}

## DeepFloyd IF
|
||||
|
||||
DeepFloyd IF is a cascading pixel diffusion model with three stages. The first stage generates a base image and the second and third stages progressively upscales the base image into a high-resolution 1024x1024 image. Use the [train_dreambooth_lora.py](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth_lora.py) or [train_dreambooth.py](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth.py) scripts to train a DeepFloyd IF model with LoRA or the full model.
|
||||
|
||||
DeepFloyd IF uses predicted variance, but the Diffusers training scripts uses predicted error so the trained DeepFloyd IF models are switched to a fixed variance schedule. The training scripts will update the scheduler config of the fully trained model for you. However, when you load the saved LoRA weights you must also update the pipeline's scheduler config.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained("DeepFloyd/IF-I-XL-v1.0", use_safetensors=True)
|
||||
|
||||
pipe.load_lora_weights("<lora weights path>")
|
||||
|
||||
# Update scheduler config to fixed variance schedule
|
||||
pipe.scheduler = pipe.scheduler.__class__.from_config(pipe.scheduler.config, variance_type="fixed_small")
|
||||
```
|
||||
|
||||
The stage 2 model requires additional validation images to upscale. You can download and use a downsized version of the training images for this.
|
||||
|
||||
```py
|
||||
from huggingface_hub import snapshot_download
|
||||
|
||||
local_dir = "./dog_downsized"
|
||||
snapshot_download(
|
||||

||||
local_dir=local_dir,
|
||||
repo_type="dataset",
|
||||
ignore_patterns=".gitattributes",
|
||||
)
|
||||
```
|
||||
|
||||
The code samples below provide a brief overview of how to train a DeepFloyd IF model with a combination of DreamBooth and LoRA. Some important parameters to note are:
|
||||
|
||||
* `--resolution=64`, a much smaller resolution is required because DeepFloyd IF is a pixel diffusion model and to work on uncompressed pixels, the input images must be smaller
|
||||
* `--pre_compute_text_embeddings`, compute the text embeddings ahead of time to save memory because the [`~transformers.T5Model`] can take up a lot of memory
|
||||
* `--tokenizer_max_length=77`, you can use a longer default text length with T5 as the text encoder but the default model encoding procedure uses a shorter text length
|
||||
* `--text_encoder_use_attention_mask`, to pass the attention mask to the text encoder

### Training tips
|
||||
|
||||
Training the DeepFloyd IF model can be challenging, but here are some tips that we've found helpful:
|
||||
|
||||
- LoRA is sufficient for training the stage 1 model because the model's low resolution makes representing finer details difficult regardless.
|
||||
- For common or simple objects, you don't necessarily need to finetune the upscaler. Make sure the prompt passed to the upscaler is adjusted to remove the new token from the instance prompt. For example, if your stage 1 prompt is "a sks dog" then your stage 2 prompt should be "a dog".
|
||||
- For finer details like faces, fully training the stage 2 upscaler is better than training the stage 2 model with LoRA. It also helps to use lower learning rates with larger batch sizes.
|
||||
- Lower learning rates should be used to train the stage 2 model.
|
||||
- The [`DDPMScheduler`] works better than the DPMSolver used in the training scripts.
|
||||

# AutoPipeline
|
||||
|
||||
🤗 Diffusers is able to complete many different tasks, and you can often reuse the same pretrained weights for multiple tasks such as text-to-image, image-to-image, and inpainting. If you're new to the library and diffusion models though, it may be difficult to know which pipeline to use for a task. For example, if you're using the [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) checkpoint for text-to-image, you might not know that you could also use it for image-to-image and inpainting by loading the checkpoint with the [`StableDiffusionImg2ImgPipeline`] and [`StableDiffusionInpaintPipeline`] classes respectively.
|
||||
Diffusers provides many pipelines for basic tasks like generating images, videos, audio, and inpainting. On top of these, there are specialized pipelines for adapters and features like upscaling, super-resolution, and more. Different pipeline classes can even use the same checkpoint because they share the same pretrained model! With so many different pipelines, it can be overwhelming to know which pipeline class to use.
|
||||
|
||||
The `AutoPipeline` class is designed to simplify the variety of pipelines in 🤗 Diffusers. It is a generic, *task-first* pipeline that lets you focus on the task. The `AutoPipeline` automatically detects the correct pipeline class to use, which makes it easier to load a checkpoint for a task without knowing the specific pipeline class name.
|
||||
The [AutoPipeline](../api/pipelines/auto_pipeline) class is designed to simplify the variety of pipelines in Diffusers. It is a generic *task-first* pipeline that lets you focus on a task ([`AutoPipelineForText2Image`], [`AutoPipelineForImage2Image`], and [`AutoPipelineForInpainting`]) without needing to know the specific pipeline class. The [AutoPipeline](../api/pipelines/auto_pipeline) automatically detects the correct pipeline class to use.
|
||||
|
||||
<Tip>
|
||||
For example, let's use the [dreamlike-art/dreamlike-photoreal-2.0](https://hf.co/dreamlike-art/dreamlike-photoreal-2.0) checkpoint.
|
||||
|
||||
Take a look at the [AutoPipeline](../api/pipelines/auto_pipeline) reference to see which tasks are supported. Currently, it supports text-to-image, image-to-image, and inpainting.
|
||||
Under the hood, [AutoPipeline](../api/pipelines/auto_pipeline):
|
||||
|
||||
</Tip>
|
||||
1. Detects a `"stable-diffusion"` class from the [model_index.json](https://hf.co/dreamlike-art/dreamlike-photoreal-2.0/blob/main/model_index.json) file.
|
||||
2. Depending on the task you're interested in, it loads the [`StableDiffusionPipeline`], [`StableDiffusionImg2ImgPipeline`], or [`StableDiffusionInpaintPipeline`]. Any parameter (`strength`, `num_inference_steps`, etc.) you would pass to these specific pipelines can also be passed to the [AutoPipeline](../api/pipelines/auto_pipeline).
|
||||
|
||||
This tutorial shows you how to use an `AutoPipeline` to automatically infer the pipeline class to load for a specific task, given the pretrained weights.
|
||||
|
||||
## Choose an AutoPipeline for your task
|
||||
|
||||
Start by picking a checkpoint. For example, if you're interested in text-to-image with the [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) checkpoint, use [`AutoPipelineForText2Image`]:

Under the hood, [`AutoPipelineForText2Image`]:
|
||||
|
||||
1. automatically detects a `"stable-diffusion"` class from the [`model_index.json`](https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/model_index.json) file
|
||||
2. loads the corresponding text-to-image [`StableDiffusionPipeline`] based on the `"stable-diffusion"` class name
|
||||
|
||||
Likewise, for image-to-image, [`AutoPipelineForImage2Image`] detects a `"stable-diffusion"` checkpoint from the `model_index.json` file and it'll load the corresponding [`StableDiffusionImg2ImgPipeline`] behind the scenes. You can also pass any additional arguments specific to the pipeline class such as `strength`, which determines the amount of noise or variation added to an input image:

Notice how the [dreamlike-art/dreamlike-photoreal-2.0](https://hf.co/dreamlike-art/dreamlike-photoreal-2.0) checkpoint is used for both text-to-image and image-to-image tasks? To save memory and avoid loading the checkpoint twice, use the [`~DiffusionPipeline.from_pipe`] method.

|
||||
|
||||
## Use multiple pipelines
|
||||
|
||||
For some workflows or if you're loading many pipelines, it is more memory-efficient to reuse the same components from a checkpoint instead of reloading them which would unnecessarily consume additional memory. For example, if you're using a checkpoint for text-to-image and you want to use it again for image-to-image, use the [`~AutoPipelineForImage2Image.from_pipe`] method. This method creates a new pipeline from the components of a previously loaded pipeline at no additional memory cost.
|
||||
|
||||
The [`~AutoPipelineForImage2Image.from_pipe`] method detects the original pipeline class and maps it to the new pipeline class corresponding to the task you want to do. For example, if you load a `"stable-diffusion"` class pipeline for text-to-image:
|
||||
|
||||
```py
|
||||
from diffusers import AutoPipelineForText2Image, AutoPipelineForImage2Image
|
||||
import torch
|
||||
|
||||
pipeline_text2img = AutoPipelineForText2Image.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16, use_safetensors=True
|
||||
)
|
||||
print(type(pipeline_text2img))
|
||||
"<class 'diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion.StableDiffusionPipeline'>"
|
||||
```
|
||||
|
||||
Then [`~AutoPipelineForImage2Image.from_pipe`] maps the original `"stable-diffusion"` pipeline class to [`StableDiffusionImg2ImgPipeline`]:
|
||||
|
||||
```py
|
||||
pipeline_img2img = AutoPipelineForImage2Image.from_pipe(pipeline_text2img)
|
||||
print(type(pipeline_img2img))
|
||||
"<class 'diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion_img2img.StableDiffusionImg2ImgPipeline'>"
|
||||
```
|
||||
|
||||
If you passed an optional argument - like disabling the safety checker - to the original pipeline, this argument is also passed on to the new pipeline:
|
||||
|
||||
```py
|
||||

This guide will demonstrate how callbacks work by a few features you can implement with them.
|
||||
|
||||
## Official callbacks
|
||||
|
||||
We provide a list of callbacks you can plug into an existing pipeline and modify the denoising loop. This is the current list of official callbacks:
|
||||
|
||||
- `SDCFGCutoffCallback`: Disables the CFG after a certain number of steps for all SD 1.5 pipelines, including text-to-image, image-to-image, inpaint, and controlnet.
|
||||
- `SDXLCFGCutoffCallback`: Disables the CFG after a certain number of steps for all SDXL pipelines, including text-to-image, image-to-image, inpaint, and controlnet.
|
||||
- `IPAdapterScaleCutoffCallback`: Disables the IP Adapter after a certain number of steps for all pipelines supporting IP-Adapter.
|
||||
|
||||
> [!TIP]
|
||||
> If you want to add a new official callback, feel free to open a [feature request](https://github.com/huggingface/diffusers/issues/new/choose) or [submit a PR](https://huggingface.co/docs/diffusers/main/en/conceptual/contribution#how-to-open-a-pr).
|
||||
|
||||
To set up a callback, you need to specify the number of denoising steps after which the callback comes into effect. You can do so by using either one of these two arguments
|
||||
|
||||
- `cutoff_step_ratio`: Float number with the ratio of the steps.
|
||||
- `cutoff_step_index`: Integer number with the exact number of the step.

## Dynamic classifier-free guidance
|
||||
|
||||
Dynamic classifier-free guidance (CFG) is a feature that allows you to disable CFG after a certain number of inference steps which can help you save compute with minimal cost to performance. The callback function for this should have the following arguments:
|
||||
|
||||
* `pipeline` (or the pipeline instance) provides access to important properties such as `num_timesteps` and `guidance_scale`. You can modify these properties by updating the underlying attributes. For this example, you'll disable CFG by setting `pipeline._guidance_scale=0.0`.
|
||||
* `step_index` and `timestep` tell you where you are in the denoising loop. Use `step_index` to turn off CFG after reaching 40% of `num_timesteps`.
|
||||
* `callback_kwargs` is a dict that contains tensor variables you can modify during the denoising loop. It only includes variables specified in the `callback_on_step_end_tensor_inputs` argument, which is passed to the pipeline's `__call__` method. Different pipelines may use different sets of variables, so please check a pipeline's `_callback_tensor_inputs` attribute for the list of variables you can modify. Some common variables include `latents` and `prompt_embeds`. For this function, change the batch size of `prompt_embeds` after setting `guidance_scale=0.0` in order for it to work properly.

||||

# Contribute a community pipeline
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 Take a look at GitHub Issue [#841](https://github.com/huggingface/diffusers/issues/841) for more context about why we're adding community pipelines to help everyone easily share their work without being slowed down.
|
||||
|
||||
</Tip>
|
||||
|
||||
Community pipelines allow you to add any additional features you'd like on top of the [`DiffusionPipeline`]. The main benefit of building on top of the `DiffusionPipeline` is anyone can load and use your pipeline by only adding one more argument, making it super easy for the community to access.
|
||||
|
||||
This guide will show you how to create a community pipeline and explain how they work. To keep things simple, you'll create a "one-step" pipeline where the `UNet` does a single forward pass and calls the scheduler once.
|
||||
|
||||
## Initialize the pipeline
|
||||
|
||||
You should start by creating a `one_step_unet.py` file for your community pipeline. In this file, create a pipeline class that inherits from the [`DiffusionPipeline`] to be able to load model weights and the scheduler configuration from the Hub. The one-step pipeline needs a `UNet` and a scheduler, so you'll need to add these as arguments to the `__init__` function:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
|
||||
def __init__(self, unet, scheduler):
|
||||
super().__init__()
|
||||
```
|
||||
|
||||
To ensure your pipeline and its components (`unet` and `scheduler`) can be saved with [`~DiffusionPipeline.save_pretrained`], add them to the `register_modules` function:
|
||||
|
||||
```diff
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
|
||||
def __init__(self, unet, scheduler):
|
||||
super().__init__()
|
||||
|
||||
+ self.register_modules(unet=unet, scheduler=scheduler)
|
||||
```
|
||||
|
||||
Cool, the `__init__` step is done and you can move to the forward pass now! 🔥
|
||||
|
||||
## Define the forward pass
|
||||
|
||||
In the forward pass, which we recommend defining as `__call__`, you have complete creative freedom to add whatever feature you'd like. For our amazing one-step pipeline, create a random image and only call the `unet` and `scheduler` once by setting `timestep=1`:
|
||||
|
||||
```diff
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
class UnetSchedulerOneForwardPipeline(DiffusionPipeline):
|
||||
def __init__(self, unet, scheduler):
|
||||
super().__init__()
|
||||
|
||||
self.register_modules(unet=unet, scheduler=scheduler)
|
||||
|
||||
+ def __call__(self):
|
||||
+ image = torch.randn(
|
||||
+ (1, self.unet.config.in_channels, self.unet.config.sample_size, self.unet.config.sample_size),
|
||||
+ )
|
||||
+ timestep = 1
|
||||
|
||||
+ model_output = self.unet(image, timestep).sample
|
||||
+ scheduler_output = self.scheduler.step(model_output, timestep, image).prev_sample
|
||||
|
||||
+ return scheduler_output
|
||||
```
|
||||
|
||||
That's it! 🚀 You can now run this pipeline by passing a `unet` and `scheduler` to it:
|
||||
|
||||
```python
|
||||
from diffusers import DDPMScheduler, UNet2DModel
|
||||
|
||||
scheduler = DDPMScheduler()
|
||||
unet = UNet2DModel()
|
||||
|
||||
pipeline = UnetSchedulerOneForwardPipeline(unet=unet, scheduler=scheduler)
|
||||
|
||||
output = pipeline()
|
||||
```
|
||||
|
||||
But what's even better is you can load pre-existing weights into the pipeline if the pipeline structure is identical. For example, you can load the [`google/ddpm-cifar10-32`](https://huggingface.co/google/ddpm-cifar10-32) weights into the one-step pipeline:
|
||||
|
||||
```python
|
||||
pipeline = UnetSchedulerOneForwardPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
|
||||
|
||||
output = pipeline()
|
||||
```
|
||||
|
||||
## Share your pipeline
|
||||
|
||||
Open a Pull Request on the 🧨 Diffusers [repository](https://github.com/huggingface/diffusers) to add your awesome pipeline in `one_step_unet.py` to the [examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) subfolder.
|
||||
|
||||
Once it is merged, anyone with `diffusers >= 0.4.0` installed can use this pipeline magically 🪄 by specifying it in the `custom_pipeline` argument:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"google/ddpm-cifar10-32", custom_pipeline="one_step_unet", use_safetensors=True
|
||||
)
|
||||
pipe()
|
||||
```
|
||||
|
||||
Another way to share your community pipeline is to upload the `one_step_unet.py` file directly to your preferred [model repository](https://huggingface.co/docs/hub/models-uploading) on the Hub. Instead of specifying the `one_step_unet.py` file, pass the model repository id to the `custom_pipeline` argument:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"google/ddpm-cifar10-32", custom_pipeline="stevhliu/one_step_unet", use_safetensors=True
|
||||
)
|
||||
```
|
||||
|
||||
Take a look at the following table to compare the two sharing workflows to help you decide the best option for you:
|
||||
|
||||
| | GitHub community pipeline | HF Hub community pipeline |
|
||||
|----------------|------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------|
|
||||
| usage | same | same |
|
||||
| review process | open a Pull Request on GitHub and undergo a review process from the Diffusers team before merging; may be slower | upload directly to a Hub repository without any review; this is the fastest workflow |
|
||||
| visibility | included in the official Diffusers repository and documentation | included on your HF Hub profile and relies on your own usage/promotion to gain visibility |
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 You can use whatever package you want in your community pipeline file - as long as the user has it installed, everything will work fine. Make sure you have one and only one pipeline class that inherits from `DiffusionPipeline` because this is automatically detected.
|
||||
|
||||
</Tip>
|
||||
|
||||
## How do community pipelines work?
|
||||
|
||||
A community pipeline is a class that inherits from [`DiffusionPipeline`] which means:
|
||||
|
||||
- It can be loaded with the [`custom_pipeline`] argument.
|
||||
- The model weights and scheduler configuration are loaded from [`pretrained_model_name_or_path`].
|
||||
- The code that implements a feature in the community pipeline is defined in a `pipeline.py` file.
|
||||
|
||||
Sometimes you can't load all the pipeline components weights from an official repository. In this case, the other components should be passed directly to the pipeline:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
from transformers import CLIPImageProcessor, CLIPModel
|
||||
|
||||
model_id = "CompVis/stable-diffusion-v1-4"
|
||||
clip_model_id = "laion/CLIP-ViT-B-32-laion2B-s34B-b79K"
|
||||
|
||||
feature_extractor = CLIPImageProcessor.from_pretrained(clip_model_id)
|
||||
clip_model = CLIPModel.from_pretrained(clip_model_id, torch_dtype=torch.float16)
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
model_id,
|
||||
custom_pipeline="clip_guided_stable_diffusion",
|
||||
clip_model=clip_model,
|
||||
feature_extractor=feature_extractor,
|
||||
scheduler=scheduler,
|
||||
torch_dtype=torch.float16,
|
||||
use_safetensors=True,
|
||||
)
|
||||
```
|
||||
|
||||
The magic behind community pipelines is contained in the following code. It allows the community pipeline to be loaded from GitHub or the Hub, and it'll be available to all 🧨 Diffusers packages.
|
||||
|
||||
```python
|
||||
# 2. Load the pipeline class, if using custom module then load it from the Hub
|
||||
# if we load from explicit class, let's use it
|
||||
if custom_pipeline is not None:
|
||||
pipeline_class = get_class_from_dynamic_module(
|
||||
custom_pipeline, module_file=CUSTOM_PIPELINE_FILE_NAME, cache_dir=custom_pipeline
|
||||
)
|
||||
elif cls != DiffusionPipeline:
|
||||
pipeline_class = cls
|
||||
else:
|
||||
diffusers_module = importlib.import_module(cls.__module__.split(".")[0])
|
||||
pipeline_class = getattr(diffusers_module, config_dict["_class_name"])
|
||||

# Control image brightness
|
||||
|
||||
The Stable Diffusion pipeline is mediocre at generating images that are either very bright or dark as explained in the [Common Diffusion Noise Schedules and Sample Steps are Flawed](https://huggingface.co/papers/2305.08891) paper. The solutions proposed in the paper are currently implemented in the [`DDIMScheduler`] which you can use to improve the lighting in your images.
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 Take a look at the paper linked above for more details about the proposed solutions!
|
||||
|
||||
</Tip>
|
||||
|
||||
One of the solutions is to train a model with *v prediction* and *v loss*. Add the following flag to the [`train_text_to_image.py`](https://github.com/huggingface/diffusers/blob/main/examples/text_to_image/train_text_to_image.py) or [`train_text_to_image_lora.py`](https://github.com/huggingface/diffusers/blob/main/examples/text_to_image/train_text_to_image_lora.py) scripts to enable `v_prediction`:
|
||||
|
||||
```bash
|
||||
--prediction_type="v_prediction"
|
||||
```
|
||||
|
||||
For example, let's use the [`ptx0/pseudo-journey-v2`](https://huggingface.co/ptx0/pseudo-journey-v2) checkpoint which has been finetuned with `v_prediction`.
|
||||
|
||||
Next, configure the following parameters in the [`DDIMScheduler`]:
|
||||
|
||||
1. `rescale_betas_zero_snr=True`, rescales the noise schedule to zero terminal signal-to-noise ratio (SNR)
|
||||
2. `timestep_spacing="trailing"`, starts sampling from the last timestep
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline, DDIMScheduler
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained("ptx0/pseudo-journey-v2", use_safetensors=True)
|
||||
|
||||
# switch the scheduler in the pipeline to use the DDIMScheduler
|
||||
pipeline.scheduler = DDIMScheduler.from_config(
|
||||
pipeline.scheduler.config, rescale_betas_zero_snr=True, timestep_spacing="trailing"
|
||||
)
|
||||
pipeline.to("cuda")
|
||||
```
|
||||
|
||||
Finally, in your call to the pipeline, set `guidance_rescale` to prevent overexposure:
|
||||
|
||||
```py
|
||||
prompt = "A lion in galaxies, spirals, nebulae, stars, smoke, iridescent, intricate detail, octane render, 8k"
|
||||
image = pipeline(prompt, guidance_rescale=0.7).images[0]
|
||||
image

Community pipelines allow you to get creative and build your own unique pipelines to share with the community. You can find all community pipelines in the [diffusers/examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) folder along with inference and training examples for how to use them. This guide showcases some of the community pipelines and hopefully it'll inspire you to create your own (feel free to open a PR with your own pipeline and we will merge it!).
|
||||
|
||||
To load a community pipeline, use the `custom_pipeline` argument in [`DiffusionPipeline`] to specify one of the files in [diffusers/examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community):
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"CompVis/stable-diffusion-v1-4", custom_pipeline="filename_in_the_community_folder", use_safetensors=True
|
||||
)
|
||||
```
|
||||
|
||||
If a community pipeline doesn't work as expected, please open a GitHub issue and mention the author.
|
||||
|
||||
You can learn more about community pipelines in the how to [load community pipelines](custom_pipeline_overview) and how to [contribute a community pipeline](contribute_pipeline) guides.

## Multilingual Stable Diffusion
|
||||
|
||||
The multilingual Stable Diffusion pipeline uses a pretrained [XLM-RoBERTa](https://huggingface.co/papluca/xlm-roberta-base-language-detection) to identify a language and the [mBART-large-50](https://huggingface.co/facebook/mbart-large-50-many-to-one-mmt) model to handle the translation. This allows you to generate images from text in 20 languages.

## MagicMix
|
||||
|
||||
[MagicMix](https://huggingface.co/papers/2210.16056) is a pipeline that can mix an image and text prompt to generate a new image that preserves the image structure. The `mix_factor` determines how much influence the prompt has on the layout generation, `kmin` controls the number of steps during the content generation process, and `kmax` determines how much information is kept in the layout of the original image.

## Community pipelines
|
||||
|
||||
Community pipelines are any [`DiffusionPipeline`] class that are different from the original implementation as specified in their paper (for example, the [`StableDiffusionControlNetPipeline`] corresponds to the [Text-to-Image Generation with ControlNet Conditioning](https://arxiv.org/abs/2302.05543) paper). They provide additional functionality or extend the original implementation of a pipeline.
|
||||
> [!TIP] Take a look at GitHub Issue [#841](https://github.com/huggingface/diffusers/issues/841) for more context about why we're adding community pipelines to help everyone easily share their work without being slowed down.
|
||||
|
||||
There are many cool community pipelines like [Speech to Image](https://github.com/huggingface/diffusers/tree/main/examples/community#speech-to-image) or [Composable Stable Diffusion](https://github.com/huggingface/diffusers/tree/main/examples/community#composable-stable-diffusion), and you can find all the official community pipelines [here](https://github.com/huggingface/diffusers/tree/main/examples/community).

|
||||
|
||||
To load any community pipeline on the Hub, pass the repository id of the community pipeline to the `custom_pipeline` argument and the model repository where you'd like to load the pipeline weights and components from. For example, the example below loads a dummy pipeline from [`hf-internal-testing/diffusers-dummy-pipeline`](https://huggingface.co/hf-internal-testing/diffusers-dummy-pipeline/blob/main/pipeline.py) and the pipeline weights and components from [`google/ddpm-cifar10-32`](https://huggingface.co/google/ddpm-cifar10-32):

|
||||
|
||||
<Tip warning={true}>
|
||||
There are two types of community pipelines, those stored on the Hugging Face Hub and those stored on Diffusers GitHub repository. Hub pipelines are completely customizable (scheduler, models, pipeline code, etc.) while Diffusers GitHub pipelines are only limited to custom pipeline code.
|
||||
|
||||
🔒 By loading a community pipeline from the Hugging Face Hub, you are trusting that the code you are loading is safe. Make sure to inspect the code online before loading and running it automatically!

||||
For more information about community pipelines, take a look at the [Community pipelines](custom_pipeline_examples) guide for how to use them and if you're interested in adding a community pipeline check out the [How to contribute a community pipeline](contribute_pipeline) guide!
|
||||
Community pipelines can also be loaded with the [`~DiffusionPipeline.from_pipe`] method which allows you to load and reuse multiple pipelines without any additional memory overhead (learn more in the [Reuse a pipeline](./loading#reuse-a-pipeline) guide). The memory requirement is determined by the largest single pipeline loaded.
|
||||
|
||||
For example, let's load a community pipeline that supports [long prompts with weighting](https://github.com/huggingface/diffusers/tree/main/examples/community#long-prompt-weighting-stable-diffusion) from a Stable Diffusion pipeline.

## Example community pipelines
|
||||
|
||||
Community pipelines are a really fun and creative way to extend the capabilities of the original pipeline with new and unique features. You can find all community pipelines in the [diffusers/examples/community](https://github.com/huggingface/diffusers/tree/main/examples/community) folder with inference and training examples for how to use them.
|
||||
|
||||
This section showcases a couple of the community pipelines and hopefully it'll inspire you to create your own (feel free to open a PR for your community pipeline and ping us for a review)!
|
||||
|
||||
> [!TIP]
|
||||
> The [`~DiffusionPipeline.from_pipe`] method is particularly useful for loading community pipelines because many of them don't have pretrained weights and add a feature on top of an existing pipeline like Stable Diffusion or Stable Diffusion XL. You can learn more about the [`~DiffusionPipeline.from_pipe`] method in the [Load with from_pipe](custom_pipeline_overview#load-with-from_pipe) section.

Now you'll load a [custom UNet](https://github.com/showlab/Show-1/blob/main/showone/models/unet_3d_condition.py), which in this example, has already been implemented in [showone_unet_3d_condition.py](https://huggingface.co/sayakpaul/show-1-base-with-code/blob/main/unet/showone_unet_3d_condition.py) for your convenience. You'll notice the [`UNet3DConditionModel`] class name is changed to `ShowOneUNet3DConditionModel` because [`UNet3DConditionModel`] already exists in Diffusers. Any components needed for the `ShowOneUNet3DConditionModel` class should be placed in showone_unet_3d_condition.py.

This script contains a custom `TextToVideoIFPipeline` class for generating videos from text. Just like the custom UNet, any code needed for the custom pipeline to work should go in the `pipeline_t2v_base_pixel.py` script.

# Distilled Stable Diffusion inference
|
||||
|
||||
[[open-in-colab]]
|
||||
|
||||
Stable Diffusion inference can be a computationally intensive process because it must iteratively denoise the latents to generate an image. To reduce the computational burden, you can use a *distilled* version of the Stable Diffusion model from [Nota AI](https://huggingface.co/nota-ai). The distilled version of their Stable Diffusion model eliminates some of the residual and attention blocks from the UNet, reducing the model size by 51% and improving latency on CPU/GPU by 43%.
|
||||
|
||||
<Tip>
|
||||
|
||||
Read this [blog post](https://huggingface.co/blog/sd_distillation) to learn more about how knowledge distillation training works to produce a faster, smaller, and cheaper generative model.
|
||||
|
||||
</Tip>
|
||||
|
||||
Let's load the distilled Stable Diffusion model and compare it against the original Stable Diffusion model:
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionPipeline
|
||||
import torch
|
||||
|
||||
distilled = StableDiffusionPipeline.from_pretrained(
|
||||
"nota-ai/bk-sdm-small", torch_dtype=torch.float16, use_safetensors=True,
|
||||
).to("cuda")
|
||||
|
||||
original = StableDiffusionPipeline.from_pretrained(
|
||||
"CompVis/stable-diffusion-v1-4", torch_dtype=torch.float16, use_safetensors=True,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Given a prompt, get the inference time for the original model:
|
||||
|
||||
```py
|
||||
import time
|
||||
|
||||
seed = 2023
|
||||
generator = torch.manual_seed(seed)
|
||||
|
||||
NUM_ITERS_TO_RUN = 3
|
||||
NUM_INFERENCE_STEPS = 25
|
||||
NUM_IMAGES_PER_PROMPT = 4
|
||||
|
||||
prompt = "a golden vase with different flowers"
|
||||
|
||||
start = time.time_ns()
|
||||
for _ in range(NUM_ITERS_TO_RUN):
|
||||
images = original(
|
||||
prompt,
|
||||
num_inference_steps=NUM_INFERENCE_STEPS,
|
||||
generator=generator,
|
||||
num_images_per_prompt=NUM_IMAGES_PER_PROMPT
|
||||
).images
|
||||
end = time.time_ns()
|
||||

|
||||
|
||||
print(f"Execution time -- {original_sd} ms\n")
|
||||
"Execution time -- 45781.5 ms"
|
||||
```
|
||||
|
||||

||||

|
||||

## Tiny AutoEncoder
|
||||
|
||||
To speed inference up even more, use a tiny distilled version of the [Stable Diffusion VAE](https://huggingface.co/sayakpaul/taesdxl-diffusers) to denoise the latents into images. Replace the VAE in the distilled Stable Diffusion model with the tiny VAE:
|
||||
|
||||
```py
|
||||
from diffusers import AutoencoderTiny
|
||||
|
||||
distilled.vae = AutoencoderTiny.from_pretrained(
|
||||
"sayakpaul/taesd-diffusers", torch_dtype=torch.float16, use_safetensors=True,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Time the distilled model and distilled VAE inference:
|
||||
|
||||
```py
|
||||
start = time.time_ns()
|
||||
for _ in range(NUM_ITERS_TO_RUN):

# Improve generation quality with FreeU
|
||||
|
||||
[[open-in-colab]]
|
||||
|
||||
The UNet is responsible for denoising during the reverse diffusion process, and there are two distinct features in its architecture:
|
||||
|
||||
1. Backbone features primarily contribute to the denoising process
|
||||
2. Skip features mainly introduce high-frequency features into the decoder module and can make the network overlook the semantics in the backbone features
|
||||
|
||||
However, the skip connection can sometimes introduce unnatural image details. [FreeU](https://hf.co/papers/2309.11497) is a technique for improving image quality by rebalancing the contributions from the UNet’s skip connections and backbone feature maps.
|
||||
|
||||
FreeU is applied during inference and it does not require any additional training. The technique works for different tasks such as text-to-image, image-to-image, and text-to-video.
|
||||
|
||||
In this guide, you will apply FreeU to the [`StableDiffusionPipeline`], [`StableDiffusionXLPipeline`], and [`TextToVideoSDPipeline`]. You need to install Diffusers from source to run the examples below.
|
||||
|
||||
## StableDiffusionPipeline
|
||||
|
||||
Load the pipeline:
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", torch_dtype=torch.float16, safety_checker=None
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Then enable the FreeU mechanism with the FreeU-specific hyperparameters. These values are scaling factors for the backbone and skip features.
|
||||
|
||||
```py
|
||||
pipeline.enable_freeu(s1=0.9, s2=0.2, b1=1.2, b2=1.4)
|
||||
```
|
||||
|
||||
The values above are from the official FreeU [code repository](https://github.com/ChenyangSi/FreeU) where you can also find [reference hyperparameters](https://github.com/ChenyangSi/FreeU#range-for-more-parameters) for different models.
|
||||
|
||||
<Tip>
|
||||
|
||||
Disable the FreeU mechanism by calling `disable_freeu()` on a pipeline.
|
||||
|
||||
</Tip>
|
||||
|
||||
And then run inference:
|
||||
|
||||
```py
|
||||
prompt = "A squirrel eating a burger"
|
||||
seed = 2023
|
||||
image = pipeline(prompt, generator=torch.manual_seed(seed)).images[0]
|
||||
image
|
||||
```
|
||||
|
||||
The figure below compares non-FreeU and FreeU results respectively for the same hyperparameters used above (`prompt` and `seed`):
|
||||
|
||||

|
||||
|
||||
|
||||
Let's see how Stable Diffusion 2 results are impacted:
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-2-1", torch_dtype=torch.float16, safety_checker=None
|
||||
).to("cuda")
|
||||
|
||||
prompt = "A squirrel eating a burger"
|
||||
seed = 2023
|
||||
|
||||
pipeline.enable_freeu(s1=0.9, s2=0.2, b1=1.1, b2=1.2)
|
||||
image = pipeline(prompt, generator=torch.manual_seed(seed)).images[0]
|
||||
image
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Stable Diffusion XL
|
||||
|
||||
Finally, let's take a look at how FreeU affects Stable Diffusion XL results:
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
import torch
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16,
|
||||
).to("cuda")
|
||||
|
||||
prompt = "A squirrel eating a burger"
|
||||
seed = 2023
|
||||
|
||||
# Comes from
|
||||
# https://wandb.ai/nasirk24/UNET-FreeU-SDXL/reports/FreeU-SDXL-Optimal-Parameters--Vmlldzo1NDg4NTUw
|
||||
pipeline.enable_freeu(s1=0.6, s2=0.4, b1=1.1, b2=1.2)
|
||||
image = pipeline(prompt, generator=torch.manual_seed(seed)).images[0]
|
||||
image
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Text-to-video generation
|
||||
|
||||
FreeU can also be used to improve video quality:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
from diffusers.utils import export_to_video
|
||||
import torch
|
||||
|
||||
model_id = "cerspense/zeroscope_v2_576w"
|
||||
pipe = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16).to("cuda")
|
||||
|
||||
prompt = "an astronaut riding a horse on mars"
|
||||
seed = 2023
|
||||
|
||||
# The values come from
|
||||
# https://github.com/lyn-rgb/FreeU_Diffusers#video-pipelines
|
||||
pipe.enable_freeu(b1=1.2, b2=1.4, s1=0.9, s2=0.2)
|
||||
video_frames = pipe(prompt, height=320, width=576, num_frames=30, generator=torch.manual_seed(seed)).frames[0]
|
||||
export_to_video(video_frames, "astronaut_rides_horse.mp4")
|
||||
```

||||

# Controlling image quality
|
||||
|
||||
The components of a diffusion model, like the UNet and scheduler, can be optimized to improve the quality of generated images leading to better details. These techniques are especially useful if you don't have the resources to simply use a larger model for inference. You can enable these techniques during inference without any additional training.
|
||||
|
||||
This guide will show you how to turn these techniques on in your pipeline and how to configure them to improve the quality of your generated images.
|
||||
|
||||
## Details
|
||||
|
||||
[FreeU](https://hf.co/papers/2309.11497) improves image details by rebalancing the UNet's backbone and skip connection weights. The skip connections can cause the model to overlook some of the backbone semantics which may lead to unnatural image details in the generated image. This technique does not require any additional training and can be applied on the fly during inference for tasks like image-to-image and text-to-video.
|
||||
|
||||
Use the [`~pipelines.StableDiffusionMixin.enable_freeu`] method on your pipeline and configure the scaling factors for the backbone (`b1` and `b2`) and skip connections (`s1` and `s2`). The number after each scaling factor corresponds to the stage in the UNet where the factor is applied. Take a look at the [FreeU](https://github.com/ChenyangSi/FreeU#parameters) repository for reference hyperparameters for different models.

# Latent Consistency Model
|
||||
|
||||
Latent Consistency Models (LCM) enable quality image generation in typically 2-4 steps making it possible to use diffusion models in almost real-time settings.
|
||||
[[open-in-colab]]
|
||||
|
||||
From the [official website](https://latent-consistency-models.github.io/):
|
||||
[Latent Consistency Models (LCMs)](https://hf.co/papers/2310.04378) enable fast high-quality image generation by directly predicting the reverse diffusion process in the latent rather than pixel space. In other words, LCMs try to predict the noiseless image from the noisy image in contrast to typical diffusion models that iteratively remove noise from the noisy image. By avoiding the iterative sampling process, LCMs are able to generate high-quality images in 2-4 steps instead of 20-30 steps.
|
||||
|
||||
> LCMs can be distilled from any pre-trained Stable Diffusion (SD) in only 4,000 training steps (~32 A100 GPU Hours) for generating high quality 768 x 768 resolution images in 2~4 steps or even one step, significantly accelerating text-to-image generation. We employ LCM to distill the Dreamshaper-V7 version of SD in just 4,000 training iterations.
|
||||
LCMs are distilled from pretrained models which requires ~32 hours of A100 compute. To speed this up, [LCM-LoRAs](https://hf.co/papers/2311.05556) train a [LoRA adapter](https://huggingface.co/docs/peft/conceptual_guides/adapter#low-rank-adaptation-lora) which have much fewer parameters to train compared to the full model. The LCM-LoRA can be plugged into a diffusion model once it has been trained.
|
||||
|
||||
For a more technical overview of LCMs, refer to [the paper](https://huggingface.co/papers/2310.04378).
|
||||
This guide will show you how to use LCMs and LCM-LoRAs for fast inference on tasks and how to use them with other adapters like ControlNet or T2I-Adapter.
|
||||
|
||||
LCM distilled models are available for [stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5), [stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0), and the [SSD-1B](https://huggingface.co/segmind/SSD-1B) model. All the checkpoints can be found in this [collection](https://huggingface.co/collections/latent-consistency/latent-consistency-models-weights-654ce61a95edd6dffccef6a8).
|
||||
|
||||
This guide shows how to perform inference with LCMs for
|
||||
- text-to-image
|
||||
- image-to-image
|
||||
- combined with style LoRAs
|
||||
- ControlNet/T2I-Adapter
|
||||
> [!TIP]
|
||||
> LCMs and LCM-LoRAs are available for Stable Diffusion v1.5, Stable Diffusion XL, and the SSD-1B model. You can find their checkpoints on the [Latent Consistency](https://hf.co/collections/latent-consistency/latent-consistency-models-weights-654ce61a95edd6dffccef6a8) Collections.
|
||||
|
||||
## Text-to-image
|
||||
|
||||
You'll use the [`StableDiffusionXLPipeline`] pipeline with the [`LCMScheduler`] and then load the LCM-LoRA. Together with the LCM-LoRA and the scheduler, the pipeline enables a fast inference workflow, overcoming the slow iterative nature of diffusion models.
|
||||
<hfoptions id="lcm-text2img">
|
||||
<hfoption id="LCM">
|
||||
|
||||
To use LCMs, you need to load the LCM checkpoint for your supported model into [`UNet2DConditionModel`] and replace the scheduler with the [`LCMScheduler`]. Then you can use the pipeline as usual, and pass a text prompt to generate an image in just 4 steps.
|
||||
|
||||
A couple of notes to keep in mind when using LCMs are:
|
||||
|
||||
* Typically, batch size is doubled inside the pipeline for classifier-free guidance. But LCM applies guidance with guidance embeddings and doesn't need to double the batch size, which leads to faster inference. The downside is that negative prompts don't work with LCM because they don't have any effect on the denoising process.
|
||||
* The ideal range for `guidance_scale` is [3., 13.] because that is what the UNet was trained with. However, disabling `guidance_scale` with a value of 1.0 is also effective in most cases.

|
||||
|
||||
* To perform classifier-free guidance, batch size is usually doubled inside the pipeline. LCM, however, applies guidance using guidance embeddings, so the batch size does not have to be doubled in this case. This leads to a faster inference time, with the drawback that negative prompts don't have any effect on the denoising process.
|
||||
* The UNet was trained using the [3., 13.] guidance scale range. So, that is the ideal range for `guidance_scale`. However, disabling `guidance_scale` using a value of 1.0 is also effective in most cases.

The downside is that negative prompts don't work with LCM because they don't have any effect on the denoising process.
|
||||
* You could use guidance with LCM-LoRAs, but it is very sensitive to high `guidance_scale` values and can lead to artifacts in the generated image. The best values we've found are between [1.0, 2.0].
|
||||
* Replace [stabilityai/stable-diffusion-xl-base-1.0](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0) with any finetuned model. For example, try using the [animagine-xl](https://huggingface.co/Linaqruf/animagine-xl) checkpoint to generate anime images with SDXL.

LCMs can be applied to image-to-image tasks too. For this example, we'll use the [LCM_Dreamshaper_v7](https://huggingface.co/SimianLuo/LCM_Dreamshaper_v7) model, but the same steps can be applied to other LCM models as well.

## Inpainting
|
||||
|
||||
To use LCM-LoRAs for inpainting, you need to replace the scheduler with the [`LCMScheduler`] and load the LCM-LoRA weights with the [`~loaders.LoraLoaderMixin.load_lora_weights`] method. Then you can use the pipeline as usual, and pass a text prompt, initial image, and mask image to generate an image in just 4 steps.

||||

||||

## Adapters
|
||||
|
||||
LCMs are compatible with adapters like LoRA, ControlNet, T2I-Adapter, and AnimateDiff. You can bring the speed of LCMs to these adapters to generate images in a certain style or condition the model on another input like a canny image.
|
||||
|
||||
### LoRA
|
||||
|
||||
[LoRA](../using-diffusers/loading_adapters#lora) adapters can be rapidly finetuned to learn a new style from just a few images and plugged into a pretrained model to generate images in that style.

Replace the scheduler with the [`LCMScheduler`]. Then you can use the [`~loaders.LoraLoaderMixin.load_lora_weights`] method to load the LCM-LoRA weights and the style LoRA you want to use. Combine both LoRA adapters with the [`~loaders.UNet2DConditionLoadersMixin.set_adapters`] method and generate a styled image in a few steps.

### ControlNet
|
||||
For this example, we'll use the [LCM_Dreamshaper_v7](https://huggingface.co/SimianLuo/LCM_Dreamshaper_v7) model with canny ControlNet, but the same steps can be applied to other LCM models as well.
|
||||
|
||||
[ControlNet](./controlnet) are adapters that can be trained on a variety of inputs like canny edge, pose estimation, or depth. The ControlNet can be inserted into the pipeline to provide additional conditioning and control to the model for more accurate generation.
|
||||
|
||||
You can find additional ControlNet models trained on other inputs in [lllyasviel's](https://hf.co/lllyasviel) repository.

|
||||
|

This example shows how to use the `lcm-sdxl` with the [Canny T2I-Adapter](TencentARC/t2i-adapter-canny-sdxl-1.0).
|
||||
[T2I-Adapter](./t2i_adapter) is an even more lightweight adapter than ControlNet, that provides an additional input to condition a pretrained model with. It is faster than ControlNet but the results may be slightly worse.
|

||||
You can find additional T2I-Adapter checkpoints trained on other inputs in [TencentArc's](https://hf.co/TencentARC) repository.

### AnimateDiff
|
||||
|
||||
[AnimateDiff](../api/pipelines/animatediff) is an adapter that adds motion to an image. It can be used with most Stable Diffusion models, effectively turning them into "video generation" models. Generating good results with a video model usually requires generating multiple frames (16-24), which can be very slow with a regular Stable Diffusion model. LCM-LoRA can speed up this process by only taking 4-8 steps for each frame.
|
||||
|
||||
Load a [`AnimateDiffPipeline`] and pass a [`MotionAdapter`] to it. Then replace the scheduler with the [`LCMScheduler`], and combine both LoRA adapters with the [`~loaders.UNet2DConditionLoadersMixin.set_adapters`] method. Now you can pass a prompt to the pipeline and generate an animated image.
|
||||
|
||||

|
||||

# Performing inference with LCM-LoRA
|
||||
|
||||
Latent Consistency Models (LCM) enable quality image generation in typically 2-4 steps making it possible to use diffusion models in almost real-time settings.
|
||||
|
||||
From the [official website](https://latent-consistency-models.github.io/):
|
||||
|
||||
> LCMs can be distilled from any pre-trained Stable Diffusion (SD) in only 4,000 training steps (~32 A100 GPU Hours) for generating high quality 768 x 768 resolution images in 2~4 steps or even one step, significantly accelerating text-to-image generation. We employ LCM to distill the Dreamshaper-V7 version of SD in just 4,000 training iterations.
|
||||
|
||||
For a more technical overview of LCMs, refer to [the paper](https://huggingface.co/papers/2310.04378).
|
||||
|
||||
However, each model needs to be distilled separately for latent consistency distillation. The core idea with LCM-LoRA is to train just a few adapter layers, the adapter being LoRA in this case.
|
||||
This way, we don't have to train the full model and keep the number of trainable parameters manageable. The resulting LoRAs can then be applied to any fine-tuned version of the model without distilling them separately.
|
||||
Additionally, the LoRAs can be applied to image-to-image, ControlNet/T2I-Adapter, inpainting, AnimateDiff etc.
|
||||
The LCM-LoRA can also be combined with other LoRAs to generate styled images in very few steps (4-8).
|
||||
|
||||
LCM-LoRAs are available for [stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5), [stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0), and the [SSD-1B](https://huggingface.co/segmind/SSD-1B) model. All the checkpoints can be found in this [collection](https://huggingface.co/collections/latent-consistency/latent-consistency-models-loras-654cdd24e111e16f0865fba6).
|
||||
|
||||
For more details about LCM-LoRA, refer to [the technical report](https://huggingface.co/papers/2311.05556).
|
||||
|
||||
This guide shows how to perform inference with LCM-LoRAs for
|
||||
- text-to-image
|
||||
- image-to-image
|
||||
- combined with styled LoRAs
|
||||
- ControlNet/T2I-Adapter
|
||||
- inpainting
|
||||
- AnimateDiff
|
||||
|
||||
Before going through this guide, we'll take a look at the general workflow for performing inference with LCM-LoRAs.
|
||||
LCM-LoRAs are similar to other Stable Diffusion LoRAs so they can be used with any [`DiffusionPipeline`] that supports LoRAs.
|
||||
|
||||
- Load the task specific pipeline and model.
|
||||
- Set the scheduler to [`LCMScheduler`].
|
||||
- Load the LCM-LoRA weights for the model.
|
||||
- Reduce the `guidance_scale` between `[1.0, 2.0]` and set the `num_inference_steps` between [4, 8].
|
||||
- Perform inference with the pipeline with the usual parameters.
|
||||
|
||||
Let's look at how we can perform inference with LCM-LoRAs for different tasks.
|
||||
|
||||
First, make sure you have [peft](https://github.com/huggingface/peft) installed, for better LoRA support.
|
||||
|
||||
```bash
|
||||
pip install -U peft
|
||||
```
|
||||
|
||||
## Text-to-image
|
||||
|
||||
You'll use the [`StableDiffusionXLPipeline`] with the scheduler: [`LCMScheduler`] and then load the LCM-LoRA. Together with the LCM-LoRA and the scheduler, the pipeline enables a fast inference workflow overcoming the slow iterative nature of diffusion models.
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import DiffusionPipeline, LCMScheduler
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
variant="fp16",
|
||||
torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|

# set scheduler
|
||||
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
# load LCM-LoRA
|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdxl")
|
||||
|
||||
prompt = "Self-portrait oil painting, a beautiful cyborg with golden hair, 8k"
|
||||
|
||||
generator = torch.manual_seed(42)
|
||||
image = pipe(
|
||||
prompt=prompt, num_inference_steps=4, generator=generator, guidance_scale=1.0
|
||||
).images[0]
|
||||
```
|
||||
|
||||

|
||||
|
||||
Notice that we use only 4 steps for generation which is way less than what's typically used for standard SDXL.
|
||||
|
||||
<Tip>
|
||||
|
||||
You may have noticed that we set `guidance_scale=1.0`, which disables classifer-free-guidance. This is because the LCM-LoRA is trained with guidance, so the batch size does not have to be doubled in this case. This leads to a faster inference time, with the drawback that negative prompts don't have any effect on the denoising process.
|
||||
|
||||
You can also use guidance with LCM-LoRA, but due to the nature of training the model is very sensitve to the `guidance_scale` values, high values can lead to artifacts in the generated images. In our experiments, we found that the best values are in the range of [1.0, 2.0].
|
||||
|
||||
</Tip>
|
||||
|
||||
### Inference with a fine-tuned model
|
||||
|
||||
As mentioned above, the LCM-LoRA can be applied to any fine-tuned version of the model without having to distill them separately. Let's look at how we can perform inference with a fine-tuned model. In this example, we'll use the [animagine-xl](https://huggingface.co/Linaqruf/animagine-xl) model, which is a fine-tuned version of the SDXL model for generating anime.
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline, LCMScheduler
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"Linaqruf/animagine-xl",
|
||||
variant="fp16",
|
||||
torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
# set scheduler
|
||||
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
# load LCM-LoRA
|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdxl")
|
||||
|
||||
prompt = "face focus, cute, masterpiece, best quality, 1girl, green hair, sweater, looking at viewer, upper body, beanie, outdoors, night, turtleneck"
|
||||
|
||||
generator = torch.manual_seed(0)
|
||||
image = pipe(
|
||||
prompt=prompt, num_inference_steps=4, generator=generator, guidance_scale=1.0
|
||||
).images[0]
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
## Image-to-image
|
||||
|
||||
LCM-LoRA can be applied to image-to-image tasks too. Let's look at how we can perform image-to-image generation with LCMs. For this example we'll use the [dreamshaper-7](https://huggingface.co/Lykon/dreamshaper-7) model and the LCM-LoRA for `stable-diffusion-v1-5 `.
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import AutoPipelineForImage2Image, LCMScheduler
|
||||
from diffusers.utils import make_image_grid, load_image
|
||||
|
||||
pipe = AutoPipelineForImage2Image.from_pretrained(
|
||||
"Lykon/dreamshaper-7",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
).to("cuda")
|
||||
|
||||
# set scheduler
|
||||
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
# load LCM-LoRA
|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdv1-5")
|
||||
|
||||
# prepare image
|
||||
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/img2img-init.png"
|
||||
init_image = load_image(url)
|
||||
prompt = "Astronauts in a jungle, cold color palette, muted colors, detailed, 8k"
|
||||
|
||||
# pass prompt and image to pipeline
|
||||
generator = torch.manual_seed(0)
|
||||
image = pipe(
|
||||
prompt,
|
||||
image=init_image,
|
||||
num_inference_steps=4,
|
||||
guidance_scale=1,
|
||||
strength=0.6,
|
||||
generator=generator
|
||||
).images[0]
|
||||
make_image_grid([init_image, image], rows=1, cols=2)
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
<Tip>
|
||||
|
||||
You can get different results based on your prompt and the image you provide. To get the best results, we recommend trying different values for `num_inference_steps`, `strength`, and `guidance_scale` parameters and choose the best one.
|
||||
|
||||
</Tip>
|
||||
|
||||
|
||||
## Combine with styled LoRAs
|
||||
|
||||
LCM-LoRA can be combined with other LoRAs to generate styled-images in very few steps (4-8). In the following example, we'll use the LCM-LoRA with the [papercut LoRA](TheLastBen/Papercut_SDXL).
|
||||
To learn more about how to combine LoRAs, refer to [this guide](https://huggingface.co/docs/diffusers/tutorials/using_peft_for_inference#combine-multiple-adapters).
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import DiffusionPipeline, LCMScheduler
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
variant="fp16",
|
||||
torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
# set scheduler
|
||||
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
# load LoRAs
|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdxl", adapter_name="lcm")
|
||||
pipe.load_lora_weights("TheLastBen/Papercut_SDXL", weight_name="papercut.safetensors", adapter_name="papercut")
|
||||
|
||||
# Combine LoRAs
|
||||
pipe.set_adapters(["lcm", "papercut"], adapter_weights=[1.0, 0.8])
|
||||
|
||||
prompt = "papercut, a cute fox"
|
||||
generator = torch.manual_seed(0)
|
||||
image = pipe(prompt, num_inference_steps=4, guidance_scale=1, generator=generator).images[0]
|
||||
image
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
## ControlNet/T2I-Adapter
|
||||
|
||||
Let's look at how we can perform inference with ControlNet/T2I-Adapter and LCM-LoRA.
|
||||
|
||||
### ControlNet
|
||||
For this example, we'll use the SD-v1-5 model and the LCM-LoRA for SD-v1-5 with canny ControlNet.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import cv2
|
||||
import numpy as np
|
||||
from PIL import Image
|
||||
|
||||
from diffusers import StableDiffusionControlNetPipeline, ControlNetModel, LCMScheduler
|
||||
from diffusers.utils import load_image
|
||||
|
||||
image = load_image(
|
||||
"https://hf.co/datasets/huggingface/documentation-images/resolve/main/diffusers/input_image_vermeer.png"
|
||||
).resize((512, 512))
|
||||
|
||||
image = np.array(image)
|
||||
|
||||
low_threshold = 100
|
||||
high_threshold = 200
|
||||
|
||||
image = cv2.Canny(image, low_threshold, high_threshold)
|
||||
image = image[:, :, None]
|
||||
image = np.concatenate([image, image, image], axis=2)
|
||||
canny_image = Image.fromarray(image)
|
||||
|
||||
controlnet = ControlNetModel.from_pretrained("lllyasviel/sd-controlnet-canny", torch_dtype=torch.float16)
|
||||
pipe = StableDiffusionControlNetPipeline.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5",
|
||||
controlnet=controlnet,
|
||||
torch_dtype=torch.float16,
|
||||
safety_checker=None,
|
||||
variant="fp16"
|
||||
).to("cuda")
|
||||
|
||||
# set scheduler
|
||||
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
||||
|
||||
# load LCM-LoRA
|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdv1-5")
|
||||
|
||||
generator = torch.manual_seed(0)
|
||||
image = pipe(
|
||||
"the mona lisa",
|
||||
image=canny_image,
|
||||
num_inference_steps=4,
|
||||
guidance_scale=1.5,
|
||||
controlnet_conditioning_scale=0.8,
|
||||
cross_attention_kwargs={"scale": 1},
|
||||
generator=generator,
|
||||
).images[0]
|
||||
make_image_grid([canny_image, image], rows=1, cols=2)
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
<Tip>
|
||||
The inference parameters in this example might not work for all examples, so we recommend you to try different values for `num_inference_steps`, `guidance_scale`, `controlnet_conditioning_scale` and `cross_attention_kwargs` parameters and choose the best one.
|
||||
</Tip>
|
||||
|
||||
### T2I-Adapter
|
||||
|
||||
This example shows how to use the LCM-LoRA with the [Canny T2I-Adapter](TencentARC/t2i-adapter-canny-sdxl-1.0) and SDXL.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import cv2
|
||||
import numpy as np
|
||||
from PIL import Image
|
||||
|
||||
from diffusers import StableDiffusionXLAdapterPipeline, T2IAdapter, LCMScheduler
|
||||
from diffusers.utils import load_image, make_image_grid
|
||||
|
||||
# Prepare image
|
||||
# Detect the canny map in low resolution to avoid high-frequency details
|
||||
image = load_image(
|
||||
"https://huggingface.co/Adapter/t2iadapter/resolve/main/figs_SDXLV1.0/org_canny.jpg"
|
||||
).resize((384, 384))
|
||||
|
||||
image = np.array(image)
|
||||
|
||||
low_threshold = 100
|
||||
high_threshold = 200
|
||||
|
||||
image = cv2.Canny(image, low_threshold, high_threshold)
|
||||
image = image[:, :, None]
|
||||
image = np.concatenate([image, image, image], axis=2)
|
||||
canny_image = Image.fromarray(image).resize((1024, 1024))
|
||||
|
||||
# load adapter
|
||||

|
||||
|

|

|
||||
|
||||
prompt = "Mystical fairy in real, magic, 4k picture, high quality"
|
||||
negative_prompt = "extra digit, fewer digits, cropped, worst quality, low quality, glitch, deformed, mutated, ugly, disfigured"
|
||||
|
||||
generator = torch.manual_seed(0)
|
||||
image = pipe(
|
||||
prompt=prompt,
|
||||
negative_prompt=negative_prompt,
|
||||

|
||||

```
|
||||
|
||||

|
||||
|
||||
|
||||
## Inpainting
|
||||
|
||||
LCM-LoRA can be used for inpainting as well.
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import AutoPipelineForInpainting, LCMScheduler
|
||||
from diffusers.utils import load_image, make_image_grid
|
||||
|
||||
pipe = AutoPipelineForInpainting.from_pretrained(
|
||||
"runwayml/stable-diffusion-inpainting",
|

torch_dtype=torch.float16,
|
||||

|
||||
).to("cuda")
|
||||
|
||||

|
||||

|
||||
|
||||

|
||||
pipe.load_lora_weights("latent-consistency/lcm-lora-sdv1-5")
|
||||
|
||||
# load base and mask image
|
||||
init_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/inpaint.png")
|
||||
mask_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/inpaint_mask.png")
|
||||
|
||||
# generator = torch.Generator("cuda").manual_seed(92)
|
||||
prompt = "concept art digital painting of an elven castle, inspired by lord of the rings, highly detailed, 8k"
|
||||

|
||||
make_image_grid([init_image, mask_image, image], rows=1, cols=3)
|
||||
```
|
||||
|
||||

|
||||
|
||||
|
||||
## AnimateDiff
|
||||
|
||||
[`AnimateDiff`] allows you to animate images using Stable Diffusion models. To get good results, we need to generate multiple frames (16-24), and doing this with standard SD models can be very slow.
|
||||
LCM-LoRA can be used to speed up the process significantly, as you just need to do 4-8 steps for each frame. Let's look at how we can perform animation with LCM-LoRA and AnimateDiff.
|
||||
|
||||
```python
|
||||

|
||||

### Style & layout control
|
||||
|
||||
[InstantStyle](https://arxiv.org/abs/2404.02733) is a plug-and-play method on top of IP-Adapter, which disentangles style and layout from image prompt to control image generation. This way, you can generate images following only the style or layout from image prompt, with significantly improved diversity. This is achieved by only activating IP-Adapters to specific parts of the model.
|
||||
|
||||
By default IP-Adapters are inserted to all layers of the model. Use the [`~loaders.IPAdapterMixin.set_ip_adapter_scale`] method with a dictionary to assign scales to IP-Adapter at different layers.
|
||||
|
||||
```py
|
||||
from diffusers import AutoPipelineForText2Image
|
||||
from diffusers.utils import load_image
|
||||
import torch
|
||||
|
||||
pipeline = AutoPipelineForText2Image.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16).to("cuda")
|
||||
pipeline.load_ip_adapter("h94/IP-Adapter", subfolder="sdxl_models", weight_name="ip-adapter_sdxl.bin")
|
||||
|
||||
scale = {
|
||||
"down": {"block_2": [0.0, 1.0]},
|
||||
"up": {"block_0": [0.0, 1.0, 0.0]},
|
||||
}
|
||||
pipeline.set_ip_adapter_scale(scale)
|
||||
```
|
||||
|
||||
This will activate IP-Adapter at the second layer in the model's down-part block 2 and up-part block 0. The former is the layer where IP-Adapter injects layout information and the latter injects style. Inserting IP-Adapter to these two layers you can generate images following both the style and layout from image prompt, but with contents more aligned to text prompt.
|
||||
|
||||
```py
|
||||
style_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/0052a70beed5bf71b92610a43a52df6d286cd5f3/diffusers/rabbit.jpg")

Having an easy way to use a diffusion system for inference is essential to 🧨 Diffusers. Diffusion systems often consist of multiple components like parameterized models, tokenizers, and schedulers that interact in complex ways. That is why we designed the [`DiffusionPipeline`] to wrap the complexity of the entire diffusion system into an easy-to-use API, while remaining flexible enough to be adapted for other use cases, such as loading each component individually as building blocks to assemble your own diffusion system.
|
||||
|
||||
Everything you need for inference or training is accessible with the `from_pretrained()` method.

Diffusion systems consist of multiple components like parameterized models and schedulers that interact in complex ways. That is why we designed the [`DiffusionPipeline`] to wrap the complexity of the entire diffusion system into an easy-to-use API. At the same time, the [`DiffusionPipeline`] is entirely customizable so you can modify each component to build a diffusion system for your use case.

This guide will show you how to load:

- pipelines from the Hub and locally
|
||||
- different components into a pipeline
|

- multiple pipelines without increasing memory usage
|
||||
- checkpoint variants such as different floating point types or non-exponential mean averaged (EMA) weights

- models and schedulers

There are two ways to load a pipeline for a task:

</Tip>
|
||||
1. Load the generic [`DiffusionPipeline`] class and allow it to automatically detect the correct pipeline class from the checkpoint.
|
||||
2. Load a specific pipeline class for a specific task.
|
||||
|
||||
The [`DiffusionPipeline`] class is the simplest and most generic way to load the latest trending diffusion model from the [Hub](https://huggingface.co/models?library=diffusers&sort=trending). The [`DiffusionPipeline.from_pretrained`] method automatically detects the correct pipeline class from the checkpoint, downloads, and caches all the required configuration and weight files, and returns a pipeline instance ready for inference.

The [`DiffusionPipeline`] class is a simple and generic way to load the latest trending diffusion model from the [Hub](https://huggingface.co/models?library=diffusers&sort=trending). It uses the [`~DiffusionPipeline.from_pretrained`] method to automatically detect the correct pipeline class for a task from the checkpoint, downloads and caches all the required configuration and weight files, and returns a pipeline ready for inference.
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
pipe = DiffusionPipeline.from_pretrained(repo_id, use_safetensors=True)
|
||||
pipeline = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", use_safetensors=True)
|
||||
```
|
||||
|
||||
You can also load a checkpoint with its specific pipeline class. The example above loaded a Stable Diffusion model; to get the same result, use the [`StableDiffusionPipeline`] class:
|
||||
This same checkpoint can also be used for an image-to-image task. The [`DiffusionPipeline`] class can handle any task as long as you provide the appropriate inputs. For example, for an image-to-image task, you need to pass an initial image to the pipeline.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", use_safetensors=True)
|
||||
|
||||
init_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/img2img-init.png")
|
||||
prompt = "Astronaut in a jungle, cold color palette, muted colors, detailed, 8k"
|
||||
image = pipeline("Astronaut in a jungle, cold color palette, muted colors, detailed, 8k", image=init_image).images[0]

Checkpoints can be loaded by their specific pipeline class if you already know it. For example, to load a Stable Diffusion model, use the [`StableDiffusionPipeline`] class.
|
||||
|
||||
```python
|
||||
from diffusers import StableDiffusionPipeline
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
pipe = StableDiffusionPipeline.from_pretrained(repo_id, use_safetensors=True)
|
||||
pipeline = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", use_safetensors=True)
|
||||
```
|
||||
|
||||
A checkpoint (such as [`CompVis/stable-diffusion-v1-4`](https://huggingface.co/CompVis/stable-diffusion-v1-4) or [`runwayml/stable-diffusion-v1-5`](https://huggingface.co/runwayml/stable-diffusion-v1-5)) may also be used for more than one task, like text-to-image or image-to-image. To differentiate what task you want to use the checkpoint for, you have to load it directly with its corresponding task-specific pipeline class:
|
||||
This same checkpoint may also be used for another task like image-to-image. To differentiate what task you want to use the checkpoint for, you have to use the corresponding task-specific pipeline class. For example, to use the same checkpoint for image-to-image, use the [`StableDiffusionImg2ImgPipeline`] class.
|
||||
|
||||
```python
|
||||
```py
|
||||
from diffusers import StableDiffusionImg2ImgPipeline
|
||||
|

repo_id = "runwayml/stable-diffusion-v1-5"

### Local pipeline
|
||||
|
||||
To load a diffusion pipeline locally, use [`git-lfs`](https://git-lfs.github.com/) to manually download the checkpoint (in this case, [`runwayml/stable-diffusion-v1-5`](https://huggingface.co/runwayml/stable-diffusion-v1-5)) to your local disk. This creates a local folder, `./stable-diffusion-v1-5`, on your disk:

git-lfs install
|
||||
git clone https://huggingface.co/runwayml/stable-diffusion-v1-5
|
||||
```
|
||||
|
||||
Then pass the local path to [`~DiffusionPipeline.from_pretrained`]:
|
||||
This creates a local folder, ./stable-diffusion-v1-5, on your disk and you should pass its path to [`~DiffusionPipeline.from_pretrained`].
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
repo_id = "./stable-diffusion-v1-5"
|
||||
stable_diffusion = DiffusionPipeline.from_pretrained(repo_id, use_safetensors=True)
|
||||
stable_diffusion = DiffusionPipeline.from_pretrained("./stable-diffusion-v1-5", use_safetensors=True)
|
||||
```
|
||||
|
||||
The [`~DiffusionPipeline.from_pretrained`] method won't download any files from the Hub when it detects a local path, but this also means it won't download and cache the latest changes to a checkpoint.

### Swap components in a pipeline
|
||||
## Customize a pipeline
|
||||
|
||||
You can customize the default components of any pipeline with another compatible component. Customization is important because:
|
||||
You can customize a pipeline by loading different components into it. This is important because you can:
|
||||
|
||||
- Changing the scheduler is important for exploring the trade-off between generation speed and quality.
|
||||
- Different components of a model are typically trained independently and you can swap out a component with a better-performing one.
|
||||
- During finetuning, usually only some components - like the UNet or text encoder - are trained.
|
||||
- change to a scheduler with faster generation speed or higher generation quality depending on your needs (call the `scheduler.compatibles` method on your pipeline to see compatible schedulers)
|
||||
- change a default pipeline component to a newer and better performing one
|
||||
|
||||
To find out which schedulers are compatible for customization, you can use the `compatibles` method:
|
||||
For example, let's customize the default [stabilityai/stable-diffusion-xl-base-1.0](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0) checkpoint with:
|
||||
|
||||
- The [`HeunDiscreteScheduler`] to generate higher quality images at the expense of slower generation speed. You must pass the `subfolder="scheduler"` parameter in [`~HeunDiscreteScheduler.from_pretrained`] to load the scheduler configuration into the correct [subfolder](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0/tree/main/scheduler) of the pipeline repository.
|
||||
- A more stable VAE that runs in fp16.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
from diffusers import StableDiffusionXLPipeline, HeunDiscreteScheduler, AutoencoderKL
|
||||
import torch
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
stable_diffusion = DiffusionPipeline.from_pretrained(repo_id, use_safetensors=True)
|
||||
stable_diffusion.scheduler.compatibles
|
||||
scheduler = HeunDiscreteScheduler.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="scheduler")
|
||||
vae = AutoencoderKL.from_pretrained("madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16, use_safetensors=True)
|
||||
```
|
||||
|
||||
Let's use the [`SchedulerMixin.from_pretrained`] method to replace the default [`PNDMScheduler`] with a more performant scheduler, [`EulerDiscreteScheduler`]. The `subfolder="scheduler"` argument is required to load the scheduler configuration from the correct [subfolder](https://huggingface.co/runwayml/stable-diffusion-v1-5/tree/main/scheduler) of the pipeline repository.
|
||||
|
||||
Then you can pass the new [`EulerDiscreteScheduler`] instance to the `scheduler` argument in [`DiffusionPipeline`]:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline, EulerDiscreteScheduler
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
scheduler = EulerDiscreteScheduler.from_pretrained(repo_id, subfolder="scheduler")
|
||||
stable_diffusion = DiffusionPipeline.from_pretrained(repo_id, scheduler=scheduler, use_safetensors=True)
|
||||
```
|
||||
|
||||
### Safety checker
|
||||
|
||||
Diffusion models like Stable Diffusion can generate harmful content, which is why 🧨 Diffusers has a [safety checker](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/stable_diffusion/safety_checker.py) to check generated outputs against known hardcoded NSFW content. If you'd like to disable the safety checker for whatever reason, pass `None` to the `safety_checker` argument:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
stable_diffusion = DiffusionPipeline.from_pretrained(repo_id, safety_checker=None, use_safetensors=True)
|
||||
"""
|
||||
You have disabled the safety checker for <class 'diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion.StableDiffusionPipeline'> by passing `safety_checker=None`. Ensure that you abide by the conditions of the Stable Diffusion license and do not expose unfiltered results in services or applications open to the public. Both the diffusers team and Hugging Face strongly recommend keeping the safety filter enabled in all public-facing circumstances, disabling it only for use cases that involve analyzing network behavior or auditing its results. For more information, please have a look at https://github.com/huggingface/diffusers/pull/254 .
|
||||
"""
|
||||
```
|
||||
|
||||
### Reuse components across pipelines
|
||||
|
||||
You can also reuse the same components in multiple pipelines to avoid loading the weights into RAM twice. Use the [`~DiffusionPipeline.components`] method to save the components:
|
||||
|
||||
```python
|
||||
from diffusers import StableDiffusionPipeline, StableDiffusionImg2ImgPipeline
|
||||
|
||||
model_id = "runwayml/stable-diffusion-v1-5"
|
||||
stable_diffusion_txt2img = StableDiffusionPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
|
||||
components = stable_diffusion_txt2img.components
|
||||
```
|
||||
|
||||
Then you can pass the `components` to another pipeline without reloading the weights into RAM:
|
||||
Now pass the new scheduler and VAE to the [`StableDiffusionXLPipeline`].
|
||||
|
||||
```py
|
||||
stable_diffusion_img2img = StableDiffusionImg2ImgPipeline(**components)
|
||||
pipeline = StableDiffusionXLPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
scheduler=scheduler,
|
||||
vae=vae,
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
You can also pass the components individually to the pipeline if you want more flexibility over which components to reuse or disable. For example, to reuse the same components in the text-to-image pipeline, except for the safety checker and feature extractor, in the image-to-image pipeline:
|
||||
## Reuse a pipeline
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionPipeline, StableDiffusionImg2ImgPipeline
|
||||
When you load multiple pipelines that share the same model components, it makes sense to reuse the shared components instead of reloading everything into memory again, especially if your hardware is memory-constrained. For example:
|
||||
|
||||
model_id = "runwayml/stable-diffusion-v1-5"
|
||||
stable_diffusion_txt2img = StableDiffusionPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
stable_diffusion_img2img = StableDiffusionImg2ImgPipeline(
|
||||
vae=stable_diffusion_txt2img.vae,
|
||||
text_encoder=stable_diffusion_txt2img.text_encoder,
|
||||
tokenizer=stable_diffusion_txt2img.tokenizer,
|
||||
unet=stable_diffusion_txt2img.unet,
|
||||
scheduler=stable_diffusion_txt2img.scheduler,
|
||||
safety_checker=None,
|
||||
feature_extractor=None,
|
||||
requires_safety_checker=False,
|
||||
)
|
||||
```
|
||||
1. You generated an image with the [`StableDiffusionPipeline`] but you want to improve its quality with the [`StableDiffusionSAGPipeline`]. Both of these pipelines share the same pretrained model, so it'd be a waste of memory to load the same model twice.
|
||||
2. You want to add a model component, like a [`MotionAdapter`](../api/pipelines/animatediff#animatediffpipeline), to [`AnimateDiffPipeline`] which was instantiated from an existing [`StableDiffusionPipeline`]. Again, both pipelines share the same pretrained model, so it'd be a waste of memory to load an entirely new pipeline again.
|
||||
|
||||
### Switch loaded pippelines
|
||||
With the [`DiffusionPipeline.from_pipe`] API, you can switch between multiple pipelines to take advantage of their different features without increasing memory-usage. It is similar to turning on and off a feature in your pipeline.
|
||||
|
||||
There are many diffuser pipelines that use the same pre-trained model as [`StableDiffusionPipeline`] and [`StableDiffusionXLPipeline`], but they implement specific features to help you achieve better generation results. This guide will show you how to use the `from_pipe` API to create multiple pipelines without increasing memory usage. By using this approach, you can easily switch between pipelines to use different features.
|
||||
> [!TIP]
|
||||
> To switch between tasks (rather than features), use the [`~DiffusionPipeline.from_pipe`] method with the [AutoPipeline](../api/pipelines/auto_pipeline) class, which automatically identifies the pipeline class based on the task (learn more in the [AutoPipeline](../tutorials/autopipeline) tutorial).
|
||||
|
||||
Let's take an example where we first create a [`StableDiffusionPipeline`] and then reuse the already loaded model components to create a [`StableDiffusionSAGPipeline`] to enhance generation quality.
|
||||
|
||||
we will generate an image of a bear eating pizza using Stable Diffusion with the IP-Adapter
|
||||
Let's start with a [`StableDiffusionPipeline`] and then reuse the loaded model components to create a [`StableDiffusionSAGPipeline`] to increase generation quality. You'll use the [`StableDiffusionPipeline`] with an [IP-Adapter](./ip_adapter) to generate a bear eating pizza.

|
||||
|
||||
Now, we can use `from_pipe` to switch to the SAG pipeline.

Now we have both `stableDiffusionPipeline` and `StableDiffusionSAGPipeline` co-existing with the same loaded model components; You can use them interchangeably without additional memory.
|
||||
If you check the memory usage, you'll see it remains the same as before because [`StableDiffusionPipeline`] and [`StableDiffusionSAGPipeline`] are sharing the same pipeline components. This allows you to use them interchangeably without any additional memory overhead.

|
||||
Let's animate the image with the [`AnimateDiffPipeline`] and also add a [`MotionAdapter`] module to the pipeline. For the [`AnimateDiffPipeline`], you need to unload the IP-Adapter first and reload it *after* you've created your new pipeline (this only applies to the [`AnimateDiffPipeline`]).
|
||||
|
||||
Let's unload the IP adapter from the SAG pipeline. It's important to note that methods like `load_ip_adapter` and `unload_ip_adapter` modify the state of the model components. Therefore, when you use these methods on one pipeline, it will affect all other pipelines that share the same model components.
|
||||
|
||||
```bash
|
||||
pipe_sag.unload_ip_adapter()
|
||||
```
|
||||
|
||||
If you try to use the Stable Diffusion pipeline with IP adapter again, it will fail
|
||||
|
||||
```bash
|
||||
generator = torch.Generator(device="cpu").manual_seed(33)
|
||||
out_sd = pipe_sd(
|
||||
prompt=prompt,
|
||||
negative_prompt=negative_prompt,

||||

|
||||
|
||||
```bash
|
||||
AttributeError: 'NoneType' object has no attribute 'image_projection_layers'
|
||||
```
|
||||
|
||||
Please note that the pipeline methods may not function properly on a new pipeline created using the `from_pipe` method. For instance, the `enable_model_cpu_offload` method installs hooks to the model components based on a unique offloading sequence for each pipeline. Therefore, if the models are executed in a different order in the new pipeline, the CPU offloading may not work correctly.
|
||||
|
||||
To ensure proper functionality, we recommend re-applying the pipeline methods on the new pipeline created using the `from_pipe` method.
|
||||
|
||||
You can also add or subtract model components when you create new pipelines. Let's now create a AnimateDiff pipeline with an additional `MotionAdapter` module
|
||||
|
||||
```bash
|
||||
```py

The [`AnimateDiffPipeline`] is more memory-intensive and consumes 15GB of memory (see the [Memory-usage of from_pipe](#memory-usage-of-from_pipe) section to learn what this means for your memory-usage).
|
||||
|
||||
When creating multiple pipelines using the `from_pipe` method, it is important to note that the memory requirement will be determined by the pipeline with the highest memory usage. This means that regardless of the number of pipelines you create, the total memory requirement will always be the same as the highest memory requirement among the pipelines.
|
||||
|
||||
For example, we have created three pipelines - `stableDiffusionPipeline`, `StableDiffusionSAGPipeline`, and `AnimateDiffPipeline` - and the `AnimateDiffPipeline` has the highest memory requirement, then the total memory usage will be based on the memory requirement of the `AnimateDiffPipeline`.
|
||||
|
||||
Therefore, creating additional pipelines will not add up to the total memory requirement. Each pipeline can be used interchangeably without any additional memory overhead.
|
||||

||||

||||
Did you know that you can use `from_pipe` with a community pipeline? Let me show you an example of using long negative prompt and prompt weighting!

### Modify from_pipe components
|
||||
|
||||
let’s run StableDiffusionPipeline with the same inputs to compare: the result from the long prompt weighting pipeline is more aligned with the text prompt.
|
||||
Pipelines loaded with [`~DiffusionPipeline.from_pipe`] can be customized with different model components or methods. However, whenever you modify the *state* of the model components, it affects all the other pipelines that share the same components. For example, if you call [`~diffusers.loaders.IPAdapterMixin.unload_ip_adapter`] on the [`StableDiffusionSAGPipeline`], you won't be able to use IP-Adapter with the [`StableDiffusionPipeline`] because it's been removed from their shared components.
|
||||
|
||||
```py
|
||||
pipe.sag_unload_ip_adapter()
|
||||
|
||||
```
|
||||
generator = torch.Generator(device="cpu").manual_seed(33)
|
||||

|
||||

|
||||
### Memory usage of from_pipe
|
||||
|
||||
You can easily switch between different pipelines using the `from_pipe` method, similar to turning on and off a feature on your pipeline. To switch between tasks, you can use the `from_pipe` method with `AutoPipeline`, which automatically identifies the pipeline class based on the task. You can find more information about this feature at the [AutoPipe Guide](https://huggingface.co/docs/diffusers/tutorials/autopipeline).
|
||||
The memory requirement of loading multiple pipelines with [`~DiffusionPipeline.from_pipe`] is determined by the pipeline with the highest memory-usage regardless of the number of pipelines you create.
|
||||
|
||||
| Pipeline | Memory usage (GB) |
|
||||
|---|---|
|
||||
| StableDiffusionPipeline | 4.400 |
|
||||
| StableDiffusionSAGPipeline | 4.400 |
|
||||
| AnimateDiffPipeline | 15.178 |
|
||||
|
||||
The [`AnimateDiffPipeline`] has the highest memory requirement, so the *total memory-usage* is based only on the [`AnimateDiffPipeline`]. Your memory-usage will not increase if you create additional pipelines as long as their memory requirements doesn't exceed that of the [`AnimateDiffPipeline`]. Each pipeline can be used interchangeably without any additional memory overhead.
|
||||
|
||||
## Safety checker
|
||||
|
||||
Diffusers implements a [safety checker](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/stable_diffusion/safety_checker.py) for Stable Diffusion models which can generate harmful content. The safety checker screens the generated output against known hardcoded not-safe-for-work (NSFW) content. If for whatever reason you'd like to disable the safety checker, pass `safety_checker=None` to the [`~DiffusionPipeline.from_pretrained`] method.
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", safety_checker=None, use_safetensors=True)
|
||||
"""
|
||||
You have disabled the safety checker for <class 'diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion.StableDiffusionPipeline'> by passing `safety_checker=None`. Ensure that you abide by the conditions of the Stable Diffusion license and do not expose unfiltered results in services or applications open to the public. Both the diffusers team and Hugging Face strongly recommend keeping the safety filter enabled in all public-facing circumstances, disabling it only for use cases that involve analyzing network behavior or auditing its results. For more information, please have a look at https://github.com/huggingface/diffusers/pull/254 .

|
||||
## Checkpoint variants
|
||||
|
||||
A checkpoint variant is usually a checkpoint whose weights are:
|
||||
|
||||
- Stored in a different floating point type for lower precision and lower storage, such as [`torch.float16`](https://pytorch.org/docs/stable/tensors.html#data-types), because it only requires half the bandwidth and storage to download. You can't use this variant if you're continuing training or using a CPU.
|
||||
- Non-exponential mean averaged (EMA) weights, which shouldn't be used for inference. You should use these to continue fine-tuning a model.
|
||||
- Stored in a different floating point type, such as [torch.float16](https://pytorch.org/docs/stable/tensors.html#data-types), because it only requires half the bandwidth and storage to download. You can't use this variant if you're continuing training or using a CPU.
|
||||
- Non-exponential mean averaged (EMA) weights which shouldn't be used for inference. You should use this variant to continue finetuning a model.
|
||||
|
||||
<Tip>
|
||||
> [!TIP]
|
||||
> When the checkpoints have identical model structures, but they were trained on different datasets and with a different training setup, they should be stored in separate repositories. For example, [stabilityai/stable-diffusion-2](https://hf.co/stabilityai/stable-diffusion-2) and [stabilityai/stable-diffusion-2-1](https://hf.co/stabilityai/stable-diffusion-2-1) are stored in separate repositories.
|
||||
|
||||
💡 When the checkpoints have identical model structures, but they were trained on different datasets and with a different training setup, they should be stored in separate repositories instead of variations (for example, [`stable-diffusion-v1-4`] and [`stable-diffusion-v1-5`]).
|
||||
Otherwise, a variant is **identical** to the original checkpoint. They have exactly the same serialization format (like [safetensors](./using_safetensors)), model structure, and their weights have identical tensor shapes.
|
||||
|
||||
</Tip>
|
||||
| **checkpoint type** | **weight name** | **argument for loading weights** |
|
||||
|---------------------|---------------------------------------------|----------------------------------|
|
||||
| original | diffusion_pytorch_model.safetensors | |
|
||||
| floating point | diffusion_pytorch_model.fp16.safetensors | `variant`, `torch_dtype` |
|
||||
| non-EMA | diffusion_pytorch_model.non_ema.safetensors | `variant` |
|
||||
|
||||
Otherwise, a variant is **identical** to the original checkpoint. They have exactly the same serialization format (like [Safetensors](./using_safetensors)), model structure, and weights that have identical tensor shapes.
|
||||
There are two important arguments for loading variants:
|
||||
|
||||
| **checkpoint type** | **weight name** | **argument for loading weights** |
|
||||
|---------------------|-------------------------------------|----------------------------------|
|
||||
| original | diffusion_pytorch_model.bin | |
|
||||
| floating point | diffusion_pytorch_model.fp16.bin | `variant`, `torch_dtype` |
|
||||
| non-EMA | diffusion_pytorch_model.non_ema.bin | `variant` |
|
||||
- `torch_dtype` specifies the floating point precision of the loaded checkpoint. For example, if you want to save bandwidth by loading a fp16 variant, you should set `variant="fp16"` and `torch_dtype=torch.float16` to *convert the weights* to fp16. Otherwise, the fp16 weights are converted to the default fp32 precision.
|
||||
|
||||
There are two important arguments to know for loading variants:
|
||||
If you only set `torch_dtype=torch.float16`, the default fp32 weights are downloaded first and then converted to fp16.
|
||||
|
||||
- `torch_dtype` defines the floating point precision of the loaded checkpoints. For example, if you want to save bandwidth by loading a `fp16` variant, you should specify `torch_dtype=torch.float16` to *convert the weights* to `fp16`. Otherwise, the `fp16` weights are converted to the default `fp32` precision. You can also load the original checkpoint without defining the `variant` argument, and convert it to `fp16` with `torch_dtype=torch.float16`. In this case, the default `fp32` weights are downloaded first, and then they're converted to `fp16` after loading.
|
||||
- `variant` specifies which files should be loaded from the repository. For example, if you want to load a non-EMA variant of a UNet from [runwayml/stable-diffusion-v1-5](https://hf.co/runwayml/stable-diffusion-v1-5/tree/main/unet), set `variant="non_ema"` to download the `non_ema` file.
|
||||
|
||||
- `variant` defines which files should be loaded from the repository. For example, if you want to load a `non_ema` variant from the [`diffusers/stable-diffusion-variants`](https://huggingface.co/diffusers/stable-diffusion-variants/tree/main/unet) repository, you should specify `variant="non_ema"` to download the `non_ema` files.

TODO(Patrick) - Make sure to uncomment this part as soon as things are deprecated.
|
||||
|
||||
#### Using `revision` to load pipeline variants is deprecated
|
||||
|
||||
Previously the `revision` argument of [`DiffusionPipeline.from_pretrained`] was heavily used to
|
||||
load model variants, e.g.:
|
||||
|
||||
```python
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipe = DiffusionPipeline.from_pretrained("CompVis/stable-diffusion-v1-4", revision="fp16", use_safetensors=True)
|
||||
```
|
||||
|
||||
However, this behavior is now deprecated since the "revision" argument should (just as it's done in GitHub) better be used to load model checkpoints from a specific commit or branch in development.
|
||||
|
||||
The above example is therefore deprecated and won't be supported anymore for `diffusers >= 1.0.0`.
|
||||
|
||||
<Tip warning={true}>
|
||||
|
||||
If you load diffusers pipelines or models with `revision="fp16"` or `revision="non_ema"`,
|
||||
please make sure to update the code and use `variant="fp16"` or `variation="non_ema"` respectively
|
||||
instead.
|
||||
|
||||
</Tip>
|
||||
-->
|
||||
|
||||
## Models
|
||||
|
||||
Models are loaded from the [`ModelMixin.from_pretrained`] method, which downloads and caches the latest version of the model weights and configurations. If the latest files are available in the local cache, [`~ModelMixin.from_pretrained`] reuses files in the cache instead of re-downloading them.
|
||||
|
||||
Models can be loaded from a subfolder with the `subfolder` argument. For example, the model weights for `runwayml/stable-diffusion-v1-5` are stored in the [`unet`](https://huggingface.co/runwayml/stable-diffusion-v1-5/tree/main/unet) subfolder:
|
||||
|
||||
```python
|
||||
from diffusers import UNet2DConditionModel
|
||||
|
||||
repo_id = "runwayml/stable-diffusion-v1-5"
|
||||
model = UNet2DConditionModel.from_pretrained(repo_id, subfolder="unet", use_safetensors=True)
|
||||
```
|
||||
|
||||
Or directly from a repository's [directory](https://huggingface.co/google/ddpm-cifar10-32/tree/main):
|
||||
|
||||
```python
|
||||
from diffusers import UNet2DModel
|
||||
|
||||
repo_id = "google/ddpm-cifar10-32"
|
||||
model = UNet2DModel.from_pretrained(repo_id, use_safetensors=True)
|
||||
```
|
||||
|
||||
You can also load and save model variants by specifying the `variant` argument in [`ModelMixin.from_pretrained`] and [`ModelMixin.save_pretrained`]:
|
||||
|
||||
```python
|
||||
from diffusers import UNet2DConditionModel
|
||||
|
||||
model = UNet2DConditionModel.from_pretrained(
|
||||
"runwayml/stable-diffusion-v1-5", subfolder="unet", variant="non_ema", use_safetensors=True
|
||||
)
|
||||
model.save_pretrained("./local-unet", variant="non_ema")
|
||||
```
|
||||
|
||||
## Schedulers
|
||||
|
||||
Schedulers are loaded from the [`SchedulerMixin.from_pretrained`] method, and unlike models, schedulers are **not parameterized** or **trained**; they are defined by a configuration file.
|
||||
|
||||
Loading schedulers does not consume any significant amount of memory and the same configuration file can be used for a variety of different schedulers.
|
||||
For example, the following schedulers are compatible with [`StableDiffusionPipeline`], which means you can load the same scheduler configuration file in any of these classes:
|
||||
|
||||
```python
|
||||
from diffusers import StableDiffusionPipeline
|
||||
from diffusers import (
|
||||
DDPMScheduler,
|
||||

||||

||||

|
||||
euler_anc = EulerAncestralDiscreteScheduler.from_pretrained(repo_id, subfolder="scheduler")
|
||||
euler = EulerDiscreteScheduler.from_pretrained(repo_id, subfolder="scheduler")
|
||||
dpm = DPMSolverMultistepScheduler.from_pretrained(repo_id, subfolder="scheduler")
|
||||

||||
pipeline = StableDiffusionPipeline.from_pretrained(repo_id, scheduler=dpm, use_safetensors=True)

### IP-Adapter Face ID models
|
||||
|
||||
The IP-Adapter FaceID models are experimental IP Adapters that use image embeddings generated by `insightface` instead of CLIP image embeddings. Some of these models also use LoRA to improve ID consistency.
|
||||
You need to install `insightface` and all its requirements to use these models.
|
||||
|
||||
<Tip warning={true}>
|

As InsightFace pretrained models are available for non-commercial research purposes, IP-Adapter-FaceID models are released exclusively for research purposes and are not intended for commercial use.

# Overview
|
||||
|
||||
🧨 Diffusers offers many pipelines, models, and schedulers for generative tasks. To make loading these components as simple as possible, we provide a single and unified method - `from_pretrained()` - that loads any of these components from either the Hugging Face [Hub](https://huggingface.co/models?library=diffusers&sort=downloads) or your local machine. Whenever you load a pipeline or model, the latest files are automatically downloaded and cached so you can quickly reuse them next time without redownloading the files.
|
||||
|
||||
This section will show you everything you need to know about loading pipelines, how to load different components in a pipeline, how to load checkpoint variants, and how to load community pipelines. You'll also learn how to load schedulers and compare the speed and quality trade-offs of using different schedulers. Finally, you'll see how to convert and load KerasCV checkpoints so you can use them in PyTorch with 🧨 Diffusers.

# Marigold Pipelines for Computer Vision Tasks
|
||||
|
||||
[Marigold](../api/pipelines/marigold) is a novel diffusion-based dense prediction approach, and a set of pipelines for various computer vision tasks, such as monocular depth estimation.
|
||||
|
||||
This guide will show you how to use Marigold to obtain fast and high-quality predictions for images and videos.
|
||||
|
||||
Each pipeline supports one Computer Vision task, which takes an input RGB image as input and produces a *prediction* of the modality of interest, such as a depth map of the input image.
|
||||
Currently, the following tasks are implemented:
|
||||
|
||||
| Pipeline | Predicted Modalities | Demos |
|
||||

|
||||
|
||||
The original checkpoints can be found under the [PRS-ETH](https://huggingface.co/prs-eth/) Hugging Face organization.
|
||||
These checkpoints are meant to work with diffusers pipelines and the [original codebase](https://github.com/prs-eth/marigold).
|
||||
The original code can also be used to train new checkpoints.

|
||||
| [prs-eth/marigold-v1-0](https://huggingface.co/prs-eth/marigold-v1-0) | Depth | The first Marigold Depth checkpoint, which predicts *affine-invariant depth* maps. The performance of this checkpoint in benchmarks was studied in the original [paper](https://huggingface.co/papers/2312.02145). Designed to be used with the `DDIMScheduler` at inference, it requires at least 10 steps to get reliable predictions. Affine-invariant depth prediction has a range of values in each pixel between 0 (near plane) and 1 (far plane); both planes are chosen by the model as part of the inference process. See the `MarigoldImageProcessor` reference for visualization utilities. |
|
||||
| [prs-eth/marigold-depth-lcm-v1-0](https://huggingface.co/prs-eth/marigold-depth-lcm-v1-0) | Depth | The fast Marigold Depth checkpoint, fine-tuned from `prs-eth/marigold-v1-0`. Designed to be used with the `LCMScheduler` at inference, it requires as little as 1 step to get reliable predictions. The prediction reliability saturates at 4 steps and declines after that. |
|
||||
| [prs-eth/marigold-normals-v0-1](https://huggingface.co/prs-eth/marigold-normals-v0-1) | Normals | A preview checkpoint for the Marigold Normals pipeline. Designed to be used with the `DDIMScheduler` at inference, it requires at least 10 steps to get reliable predictions. The surface normals predictions are unit-length 3D vectors with values in the range from -1 to 1. *This checkpoint will be phased out after the release of `v1-0` version.* |

|
||||
The examples below are mostly given for depth prediction, but they can be universally applied with other supported modalities.
|
||||
We showcase the predictions using the same input image of Albert Einstein generated by Midjourney.
|
||||
This makes it easier to compare visualizations of the predictions across various modalities and checkpoints.

### Depth Prediction Quick Start
|
||||
|
||||
To get the first depth prediction, load `prs-eth/marigold-depth-lcm-v1-0` checkpoint into `MarigoldDepthPipeline` pipeline, put the image through the pipeline, and save the predictions:
|
||||
|
||||
```python
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(
|
||||
"prs-eth/marigold-depth-lcm-v1-0", variant="fp16", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
depth = pipe(image)
|
||||
|
||||
vis = pipe.image_processor.visualize_depth(depth.prediction)
|
||||
vis[0].save("einstein_depth.png")
|
||||
|
||||
depth_16bit = pipe.image_processor.export_depth_to_16bit_png(depth.prediction)
|
||||
depth_16bit[0].save("einstein_depth_16bit.png")
|
||||
```
|
||||
|
||||
The visualization function for depth [`~pipelines.marigold.marigold_image_processing.MarigoldImageProcessor.visualize_depth`] applies one of [matplotlib's colormaps](https://matplotlib.org/stable/users/explain/colors/colormaps.html) (`Spectral` by default) to map the predicted pixel values from a single-channel `[0, 1]` depth range into an RGB image.
|
||||
With the `Spectral` colormap, pixels with near depth are painted red, and far pixels are assigned blue color.
|
||||
The 16-bit PNG file stores the single channel values mapped linearly from the `[0, 1]` range into `[0, 65535]`.
|
||||
Below are the raw and the visualized predictions; as can be seen, dark areas (mustache) are easier to distinguish in the visualization:

|

### Surface Normals Prediction Quick Start
|
||||
|
||||
Load `prs-eth/marigold-normals-lcm-v0-1` checkpoint into `MarigoldNormalsPipeline` pipeline, put the image through the pipeline, and save the predictions:
|
||||
|
||||
```python
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
pipe = diffusers.MarigoldNormalsPipeline.from_pretrained(
|
||||
"prs-eth/marigold-normals-lcm-v0-1", variant="fp16", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
normals = pipe(image)
|
||||
|
||||
vis = pipe.image_processor.visualize_normals(normals.prediction)
|
||||
vis[0].save("einstein_normals.png")
|
||||
```
|
||||
|
||||
The visualization function for normals [`~pipelines.marigold.marigold_image_processing.MarigoldImageProcessor.visualize_normals`] maps the three-dimensional prediction with pixel values in the range `[-1, 1]` into an RGB image.
|
||||
The visualization function supports flipping surface normals axes to make the visualization compatible with other choices of the frame of reference.
|
||||
Conceptually, each pixel is painted according to the surface normal vector in the frame of reference, where `X` axis points right, `Y` axis points up, and `Z` axis points at the viewer.
|
||||
Below is the visualized prediction:
|
||||
|
||||
<div class="flex gap-4" style="justify-content: center; width: 100%;">
|
||||
<div style="flex: 1 1 50%; max-width: 50%;">
|
||||
<img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/marigold/marigold_einstein_lcm_normals.png"/>
|
||||
<figcaption class="mt-1 text-center text-sm text-gray-500">
|
||||
Predicted surface normals visualization
|
||||
</figcaption>
|
||||
</div>
|
||||
</div>
|
||||
|
||||
In this example, the nose tip almost certainly has a point on the surface, in which the surface normal vector points straight at the viewer, meaning that its coordinates are `[0, 0, 1]`.
|
||||
This vector maps to the RGB `[128, 128, 255]`, which corresponds to the violet-blue color.
|
||||
Similarly, a surface normal on the cheek in the right part of the image has a large `X` component, which increases the red hue.
|
||||
Points on the shoulders pointing up with a large `Y` promote green color.
|
||||
|
||||
### Speeding up inference
|
||||
|
||||
The above quick start snippets are already optimized for speed: they load the LCM checkpoint, use the `fp16` variant of weights and computation, and perform just one denoising diffusion step.
|
||||
The `pipe(image)` call completes in 280ms on RTX 3090 GPU.
|
||||
Internally, the input image is encoded with the Stable Diffusion VAE encoder, then the U-Net performs one denoising step, and finally, the prediction latent is decoded with the VAE decoder into pixel space.
|
||||
In this case, two out of three module calls are dedicated to converting between pixel and latent space of LDM.
|
||||
Because Marigold's latent space is compatible with the base Stable Diffusion, it is possible to speed up the pipeline call by more than 3x (85ms on RTX 3090) by using a [lightweight replacement of the SD VAE](../api/models/autoencoder_tiny):
|
||||
|
||||
```diff
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(
|
||||
"prs-eth/marigold-depth-lcm-v1-0", variant="fp16", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
+ pipe.vae = diffusers.AutoencoderTiny.from_pretrained(
|
||||
+ "madebyollin/taesd", torch_dtype=torch.float16
|
||||
+ ).cuda()
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
depth = pipe(image)
|
||||
```
|
||||
|
||||
As suggested in [Optimizations](../optimization/torch2.0#torch.compile), adding `torch.compile` may squeeze extra performance depending on the target hardware:
|
||||
|
||||
```diff
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(
|
||||
"prs-eth/marigold-depth-lcm-v1-0", variant="fp16", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
+ pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True)
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
depth = pipe(image)
|
||||
```
|
||||
|
||||
## Qualitative Comparison with Depth Anything
|
||||
|
||||
With the above speed optimizations, Marigold delivers predictions with more details and faster than [Depth Anything](https://huggingface.co/docs/transformers/main/en/model_doc/depth_anything) with the largest checkpoint [LiheYoung/depth-anything-large-hf](https://huggingface.co/LiheYoung/depth-anything-large-hf):

|
||||
|
||||
## Maximizing Precision and Ensembling
|
||||
|
||||
Marigold pipelines have a built-in ensembling mechanism combining multiple predictions from different random latents.
|
||||
This is a brute-force way of improving the precision of predictions, capitalizing on the generative nature of diffusion.
|
||||
The ensembling path is activated automatically when the `ensemble_size` argument is set greater than `1`.
|
||||
When aiming for maximum precision, it makes sense to adjust `num_inference_steps` simultaneously with `ensemble_size`.
|
||||
The recommended values vary across checkpoints but primarily depend on the scheduler type.
|
||||
The effect of ensembling is particularly well-seen with surface normals:
|
||||
|
||||
```python
|
||||
import diffusers
|
||||
|
||||
model_path = "prs-eth/marigold-normals-v1-0"
|
||||
|
||||
model_paper_kwargs = {
|
||||
diffusers.schedulers.DDIMScheduler: {
|
||||
"num_inference_steps": 10,
|
||||
"ensemble_size": 10,
|
||||
},
|
||||
diffusers.schedulers.LCMScheduler: {
|
||||
"num_inference_steps": 4,
|
||||
"ensemble_size": 5,
|
||||
},
|
||||
}
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
|
||||
pipe = diffusers.MarigoldNormalsPipeline.from_pretrained(model_path).to("cuda")
|
||||
pipe_kwargs = model_paper_kwargs[type(pipe.scheduler)]
|
||||
|
||||
depth = pipe(image, **pipe_kwargs)
|
||||
|
||||
vis = pipe.image_processor.visualize_normals(depth.prediction)
|
||||
vis[0].save("einstein_normals.png")
|
||||
```
|
||||
|
||||
<div class="flex gap-4">
|
||||
<div style="flex: 1 1 50%; max-width: 50%;">

</div>
|
||||
|
||||
As can be seen, all areas with fine-grained structurers, such as hair, got more conservative and on average more correct predictions.
|
||||
Such a result is more suitable for precision-sensitive downstream tasks, such as 3D reconstruction.
|
||||
|
||||
## Quantitative Evaluation
|
||||
|
||||
To evaluate Marigold quantitatively in standard leaderboards and benchmarks (such as NYU, KITTI, and other datasets), follow the evaluation protocol outlined in the paper: load the full precision fp32 model and use appropriate values for `num_inference_steps` and `ensemble_size`.
|
||||
Optionally seed randomness to ensure reproducibility. Maximizing `batch_size` will deliver maximum device utilization.
|
||||
|
||||
```python
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
device = "cuda"
|
||||
seed = 2024
|
||||
model_path = "prs-eth/marigold-v1-0"
|
||||
|
||||
model_paper_kwargs = {
|
||||
diffusers.schedulers.DDIMScheduler: {
|
||||
"num_inference_steps": 50,
|
||||
"ensemble_size": 10,
|
||||
},
|
||||
diffusers.schedulers.LCMScheduler: {
|
||||
"num_inference_steps": 4,
|
||||
"ensemble_size": 10,
|
||||
},
|
||||
}
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
|
||||
generator = torch.Generator(device=device).manual_seed(seed)
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(model_path).to(device)
|
||||
pipe_kwargs = model_paper_kwargs[type(pipe.scheduler)]
|
||||
|
||||
depth = pipe(image, generator=generator, **pipe_kwargs)
|
||||
|
||||
# evaluate metrics
|
||||
```
|
||||
|
||||
## Using Predictive Uncertainty
|
||||
|
||||
The ensembling mechanism built into Marigold pipelines combines multiple predictions obtained from different random latents.
|
||||
As a side effect, it can be used to quantify epistemic (model) uncertainty; simply specify `ensemble_size` greater than 1 and set `output_uncertainty=True`.
|
||||
The resulting uncertainty will be available in the `uncertainty` field of the output.
|
||||
It can be visualized as follows:
|
||||
|
||||
```python
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(
|
||||
"prs-eth/marigold-depth-lcm-v1-0", variant="fp16", torch_dtype=torch.float16
|
||||
).to("cuda")
|
||||
|
||||
image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
|
||||
depth = pipe(
|
||||
image,
|
||||
ensemble_size=10, # any number greater than 1; higher values yield higher precision
|
||||
output_uncertainty=True,
|
||||
)
|
||||
|
||||
uncertainty = pipe.image_processor.visualize_uncertainty(depth.uncertainty)
|
||||
uncertainty[0].save("einstein_depth_uncertainty.png")
|
||||
```
|
||||
|
||||
<div class="flex gap-4">

||||
<div style="flex: 1 1 50%; max-width: 50%;">

</div>
|
||||
|
||||
The interpretation of uncertainty is easy: higher values (white) correspond to pixels, where the model struggles to make consistent predictions.
|
||||
Evidently, the depth model is the least confident around edges with discontinuity, where the object depth changes drastically.
|
||||
The surface normals model is the least confident in fine-grained structures, such as hair, and dark areas, such as the collar.
|
||||
|
||||
## Frame-by-frame Video Processing with Temporal Consistency
|
||||
|
||||
Due to Marigold's generative nature, each prediction is unique and defined by the random noise sampled for the latent initialization.
|
||||
This becomes an obvious drawback compared to traditional end-to-end dense regression networks, as exemplified in the following videos:
|
||||

||||

|

To address this issue, it is possible to pass `latents` argument to the pipelines, which defines the starting point of diffusion.
|
||||
Empirically, we found that a convex combination of the very same starting point noise latent and the latent corresponding to the previous frame prediction give sufficiently smooth results, as implemented in the snippet below:
|
||||
|
||||
```python
|
||||
import imageio
|
||||
from PIL import Image
|
||||
from tqdm import tqdm
|
||||
import diffusers
|
||||
import torch
|
||||
|
||||
device = "cuda"
|
||||
path_in = "obama.mp4"
|
||||
path_out = "obama_depth.gif"
|
||||
|
||||
pipe = diffusers.MarigoldDepthPipeline.from_pretrained(
|
||||
"prs-eth/marigold-depth-lcm-v1-0", variant="fp16", torch_dtype=torch.float16
|
||||
).to(device)
|
||||
pipe.vae = diffusers.AutoencoderTiny.from_pretrained(
|
||||
"madebyollin/taesd", torch_dtype=torch.float16
|
||||
).to(device)
|
||||
pipe.set_progress_bar_config(disable=True)
|
||||
|
||||
with imageio.get_reader(path_in) as reader:
|
||||
size = reader.get_meta_data()['size']
|
||||
last_frame_latent = None
|
||||
latent_common = torch.randn(
|
||||
(1, 4, 768 * size[1] // (8 * max(size)), 768 * size[0] // (8 * max(size)))
|
||||
).to(device=device, dtype=torch.float16)
|
||||
|
||||
out = []
|
||||
for frame_id, frame in tqdm(enumerate(reader), desc="Processing Video"):
|
||||
frame = Image.fromarray(frame)
|
||||
latents = latent_common
|
||||
if last_frame_latent is not None:
|
||||
latents = 0.9 * latents + 0.1 * last_frame_latent
|
||||
|
||||
depth = pipe(
|
||||
frame, match_input_resolution=False, latents=latents, output_latent=True
|
||||
)
|
||||
last_frame_latent = depth.latent
|
||||
out.append(pipe.image_processor.visualize_depth(depth.prediction)[0])
|
||||
|
||||
diffusers.utils.export_to_gif(out, path_out, fps=reader.get_meta_data()['fps'])
|
||||
```
|
||||
|
||||
Here, the diffusion process starts from the given computed latent.
|
||||
The pipeline sets `output_latent=True` to access `out.latent` and computes its contribution to the next frame's latent initialization.
|
||||
The result is much more stable now:

## Marigold for ControlNet
|
||||
|
||||
A very common application for depth prediction with diffusion models comes in conjunction with ControlNet.
|
||||
Depth crispness plays a crucial role in obtaining high-quality results from ControlNet.
|
||||
As seen in comparisons with other methods above, Marigold excels at that task.
|
||||
The snippet below demonstrates how to load an image, compute depth, and pass it into ControlNet in a compatible format:
|
||||
|
||||
```python
|
||||
import torch
|
||||
import diffusers
|
||||
|
||||
device = "cuda"
|
||||

).to(device)
|

# Load different Stable Diffusion formats
|
||||
# Model files and layouts
|
||||
|
||||
[[open-in-colab]]
|
||||
|
||||
Stable Diffusion models are available in different formats depending on the framework they're trained and saved with, and where you download them from. Converting these formats for use in 🤗 Diffusers allows you to use all the features supported by the library, such as [using different schedulers](schedulers) for inference, [building your custom pipeline](write_own_pipeline), and a variety of techniques and methods for [optimizing inference speed](../optimization/opt_overview).
|
||||
Diffusion models are saved in various file types and organized in different layouts. Diffusers stores model weights as safetensors files in *Diffusers-multifolder* layout and it also supports loading files (like safetensors and ckpt files) from a *single-file* layout which is commonly used in the diffusion ecosystem.
|
||||
|
||||
<Tip>
|
||||
Each layout has its own benefits and use cases, and this guide will show you how to load the different files and layouts, and how to convert them.
|
||||
|
||||
We highly recommend using the `.safetensors` format because it is more secure than traditional pickled files which are vulnerable and can be exploited to execute any code on your machine (learn more in the [Load safetensors](using_safetensors) guide).
|
||||
## Files
|
||||
|
||||
</Tip>
|
||||
PyTorch model weights are typically saved with Python's [pickle](https://docs.python.org/3/library/pickle.html) utility as ckpt or bin files. However, pickle is not secure and pickled files may contain malicious code that can be executed. This vulnerability is a serious concern given the popularity of model sharing. To address this security issue, the [Safetensors](https://hf.co/docs/safetensors) library was developed as a secure alternative to pickle, which saves models as safetensors files.
|
||||
|
||||
This guide will show you how to convert other Stable Diffusion formats to be compatible with 🤗 Diffusers.
|
||||
### safetensors
|
||||
|
||||
## PyTorch .ckpt
|
||||
> [!TIP]
|
||||
> Learn more about the design decisions and why safetensor files are preferred for saving and loading model weights in the [Safetensors audited as really safe and becoming the default](https://blog.eleuther.ai/safetensors-security-audit/) blog post.
|
||||
|
||||
The checkpoint - or `.ckpt` - format is commonly used to store and save models. The `.ckpt` file contains the entire model and is typically several GBs in size. While you can load and use a `.ckpt` file directly with the [`~StableDiffusionPipeline.from_single_file`] method, it is generally better to convert the `.ckpt` file to 🤗 Diffusers so both formats are available.
|
||||
[Safetensors](https://hf.co/docs/safetensors) is a safe and fast file format for securely storing and loading tensors. Safetensors restricts the header size to limit certain types of attacks, supports lazy loading (useful for distributed setups), and has generally faster loading speeds.
|
||||
|
||||
There are two options for converting a `.ckpt` file: use a Space to convert the checkpoint or convert the `.ckpt` file with a script.
|
||||
Make sure you have the [Safetensors](https://hf.co/docs/safetensors) library installed.
|
||||
|
||||
### Convert with a Space
|
||||
|
||||
The easiest and most convenient way to convert a `.ckpt` file is to use the [SD to Diffusers](https://huggingface.co/spaces/diffusers/sd-to-diffusers) Space. You can follow the instructions on the Space to convert the `.ckpt` file.
|
||||
|
||||
This approach works well for basic models, but it may struggle with more customized models. You'll know the Space failed if it returns an empty pull request or error. In this case, you can try converting the `.ckpt` file with a script.
|
||||
|
||||
### Convert with a script
|
||||
|
||||
🤗 Diffusers provides a [conversion script](https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py) for converting `.ckpt` files. This approach is more reliable than the Space above.
|
||||
|
||||
Before you start, make sure you have a local clone of 🤗 Diffusers to run the script and log in to your Hugging Face account so you can open pull requests and push your converted model to the Hub.
|
||||
|
||||
```bash
|
||||
huggingface-cli login
|
||||
```py
|
||||
!pip install safetensors
|
||||
```
|
||||
|
||||
To use the script:
|
||||
Safetensors stores weights in a safetensors file. Diffusers loads safetensors files by default if they're available and the Safetensors library is installed. There are two ways safetensors files can be organized:
|
||||
|
||||
1. Git clone the repository containing the `.ckpt` file you want to convert. For this example, let's convert this [TemporalNet](https://huggingface.co/CiaraRowles/TemporalNet) `.ckpt` file:
|
||||
1. Diffusers-multifolder layout: there may be several separate safetensors files, one for each pipeline component (text encoder, UNet, VAE), organized in subfolders (check out the [runwayml/stable-diffusion-v1-5](https://hf.co/runwayml/stable-diffusion-v1-5/tree/main) repository as an example)
|
||||
2. single-file layout: all the model weights may be saved in a single file (check out the [WarriorMama777/OrangeMixs](https://hf.co/WarriorMama777/OrangeMixs/tree/main/Models/AbyssOrangeMix) repository as an example)
|
||||
|
||||
```bash
|
||||
git lfs install
|
||||
git clone https://huggingface.co/CiaraRowles/TemporalNet
|
||||
```
|
||||
<hfoptions id="safetensors">
|
||||
<hfoption id="multifolder">
|
||||
|
||||
2. Open a pull request on the repository where you're converting the checkpoint from:
|
||||
|
||||
```bash
|
||||
cd TemporalNet && git fetch origin refs/pr/13:pr/13
|
||||
git checkout pr/13
|
||||
```
|
||||
|
||||
3. There are several input arguments to configure in the conversion script, but the most important ones are:
|
||||
|
||||
- `checkpoint_path`: the path to the `.ckpt` file to convert.
|
||||
- `original_config_file`: a YAML file defining the configuration of the original architecture. If you can't find this file, try searching for the YAML file in the GitHub repository where you found the `.ckpt` file.
|
||||
- `dump_path`: the path to the converted model.
|
||||
|
||||
For example, you can take the `cldm_v15.yaml` file from the [ControlNet](https://github.com/lllyasviel/ControlNet/tree/main/models) repository because the TemporalNet model is a Stable Diffusion v1.5 and ControlNet model.
|
||||
|
||||
4. Now you can run the script to convert the `.ckpt` file:
|
||||
|
||||
```bash
|
||||
python ../diffusers/scripts/convert_original_stable_diffusion_to_diffusers.py --checkpoint_path temporalnetv3.ckpt --original_config_file cldm_v15.yaml --dump_path ./ --controlnet
|
||||
```
|
||||
|
||||
5. Once the conversion is done, upload your converted model and test out the resulting [pull request](https://huggingface.co/CiaraRowles/TemporalNet/discussions/13)!
|
||||
|
||||
```bash
|
||||
git push origin pr/13:refs/pr/13
|
||||
```
|
||||
|
||||
## Keras .pb or .h5
|
||||
|
||||
<Tip warning={true}>
|
||||
|
||||
🧪 This is an experimental feature. Only Stable Diffusion v1 checkpoints are supported by the Convert KerasCV Space at the moment.
|
||||
|
||||
</Tip>
|
||||
|
||||
[KerasCV](https://keras.io/keras_cv/) supports training for [Stable Diffusion](https://github.com/keras-team/keras-cv/blob/master/keras_cv/models/stable_diffusion) v1 and v2. However, it offers limited support for experimenting with Stable Diffusion models for inference and deployment whereas 🤗 Diffusers has a more complete set of features for this purpose, such as different [noise schedulers](https://huggingface.co/docs/diffusers/using-diffusers/schedulers), [flash attention](https://huggingface.co/docs/diffusers/optimization/xformers), and [other
|
||||
optimization techniques](https://huggingface.co/docs/diffusers/optimization/fp16).
|
||||
|
||||
The [Convert KerasCV](https://huggingface.co/spaces/sayakpaul/convert-kerascv-sd-diffusers) Space converts `.pb` or `.h5` files to PyTorch, and then wraps them in a [`StableDiffusionPipeline`] so it is ready for inference. The converted checkpoint is stored in a repository on the Hugging Face Hub.
|
||||
|
||||
For this example, let's convert the [`sayakpaul/textual-inversion-kerasio`](https://huggingface.co/sayakpaul/textual-inversion-kerasio/tree/main) checkpoint which was trained with Textual Inversion. It uses the special token `<my-funny-cat>` to personalize images with cats.
|
||||
|
||||
The Convert KerasCV Space allows you to input the following:
|
||||
|
||||
* Your Hugging Face token.
|
||||
* Paths to download the UNet and text encoder weights from. Depending on how the model was trained, you don't necessarily need to provide the paths to both the UNet and text encoder. For example, Textual Inversion only requires the embeddings from the text encoder and a text-to-image model only requires the UNet weights.
|
||||
* Placeholder token is only applicable for textual inversion models.
|
||||
* The `output_repo_prefix` is the name of the repository where the converted model is stored.
|
||||
|
||||
Click the **Submit** button to automatically convert the KerasCV checkpoint! Once the checkpoint is successfully converted, you'll see a link to the new repository containing the converted checkpoint. Follow the link to the new repository, and you'll see the Convert KerasCV Space generated a model card with an inference widget to try out the converted model.
|
||||
|
||||
If you prefer to run inference with code, click on the **Use in Diffusers** button in the upper right corner of the model card to copy and paste the code snippet:
|
||||
Use the [`~DiffusionPipeline.from_pretrained`] method to load a model with safetensors files stored in multiple folders.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"sayakpaul/textual-inversion-cat-kerascv_sd_diffusers_pipeline", use_safetensors=True
|
||||
"runwayml/stable-diffusion-v1-5",
|
||||
use_safetensors=True
|
||||
)
|
||||
```
|
||||
|
||||
Then, you can generate an image like:
|
||||
</hfoption>
|
||||
<hfoption id="single file">
|
||||
|
||||
Use the [`~loaders.FromSingleFileMixin.from_single_file`] method to load a model with all the weights stored in a single safetensors file.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
from diffusers import StableDiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"sayakpaul/textual-inversion-cat-kerascv_sd_diffusers_pipeline", use_safetensors=True
|
||||
pipeline = StableDiffusionPipeline.from_single_file(
|
||||
"https://huggingface.co/WarriorMama777/OrangeMixs/blob/main/Models/AbyssOrangeMix/AbyssOrangeMix.safetensors"
|
||||
)
|
||||
pipeline.to("cuda")
|
||||
|
||||
placeholder_token = "<my-funny-cat-token>"
|
||||
prompt = f"two {placeholder_token} getting married, photorealistic, high quality"
|
||||
image = pipeline(prompt, num_inference_steps=50).images[0]
|
||||
```
|
||||
|
||||
## A1111 LoRA files
|
||||
</hfoption>
|
||||
</hfoptions>
|
||||
|
||||
[Automatic1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui) (A1111) is a popular web UI for Stable Diffusion that supports model sharing platforms like [Civitai](https://civitai.com/). Models trained with the Low-Rank Adaptation (LoRA) technique are especially popular because they're fast to train and have a much smaller file size than a fully finetuned model. 🤗 Diffusers supports loading A1111 LoRA checkpoints with [`~loaders.LoraLoaderMixin.load_lora_weights`]:
|
||||
#### LoRA files
|
||||
|
||||
[LoRA](https://hf.co/docs/peft/conceptual_guides/adapter#low-rank-adaptation-lora) is a lightweight adapter that is fast and easy to train, making them especially popular for generating images in a certain way or style. These adapters are commonly stored in a safetensors file, and are widely popular on model sharing platforms like [civitai](https://civitai.com/).
|
||||
|
||||
LoRAs are loaded into a base model with the [`~loaders.LoraLoaderMixin.load_lora_weights`] method.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
import torch
|
||||
|
||||
# base model
|
||||
pipeline = StableDiffusionXLPipeline.from_pretrained(
|
||||
"Lykon/dreamshaper-xl-1-0", torch_dtype=torch.float16, variant="fp16"
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Download a LoRA checkpoint from Civitai; this example uses the [Blueprintify SD XL 1.0](https://civitai.com/models/150986/blueprintify-sd-xl-10) checkpoint, but feel free to try out any LoRA checkpoint!
|
||||
# download LoRA weights
|
||||
!wget https://civitai.com/api/download/models/168776 -O blueprintify.safetensors
|
||||
|
||||
```py
|
||||
# uncomment to download the safetensor weights
|
||||
#!wget https://civitai.com/api/download/models/168776 -O blueprintify.safetensors
|
||||
```
|
||||
|
||||
Load the LoRA checkpoint into the pipeline with the [`~loaders.LoraLoaderMixin.load_lora_weights`] method:
|
||||
|
||||
```py
|
||||
# load LoRA weights
|
||||
pipeline.load_lora_weights(".", weight_name="blueprintify.safetensors")
|
||||
```
|
||||
|
||||
Now you can use the pipeline to generate images:
|
||||
|
||||
```py
|
||||
prompt = "bl3uprint, a highly detailed blueprint of the empire state building, explaining how to build all parts, many txt, blueprint grid backdrop"
|
||||
negative_prompt = "lowres, cropped, worst quality, low quality, normal quality, artifacts, signature, watermark, username, blurry, more than one bridge, bad architecture"

### ckpt
|
||||
|
||||
> [!WARNING]
|
||||
> Pickled files may be unsafe because they can be exploited to execute malicious code. It is recommended to use safetensors files instead where possible, or convert the weights to safetensors files.
|
||||
|
||||
PyTorch's [torch.save](https://pytorch.org/docs/stable/generated/torch.save.html) function uses Python's [pickle](https://docs.python.org/3/library/pickle.html) utility to serialize and save models. These files are saved as a ckpt file and they contain the entire model's weights.
|
||||
|
||||
Use the [`~loaders.FromSingleFileMixin.from_single_file`] method to directly load a ckpt file.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionPipeline
|
||||
|
||||
pipeline = StableDiffusionPipeline.from_single_file(

|
||||
## Storage layout
|
||||
|
||||
There are two ways model files are organized, either in a Diffusers-multifolder layout or in a single-file layout. The Diffusers-multifolder layout is the default, and each component file (text encoder, UNet, VAE) is stored in a separate subfolder. Diffusers also supports loading models from a single-file layout where all the components are bundled together.
|
||||
|
||||
### Diffusers-multifolder
|
||||
|
||||
The Diffusers-multifolder layout is the default storage layout for Diffusers. Each component's (text encoder, UNet, VAE) weights are stored in a separate subfolder. The weights can be stored as safetensors or ckpt files.
|
||||
|
||||

|
||||
</div>
|
||||
</div>
|
||||
|
||||
To load from Diffusers-multifolder layout, use the [`~DiffusionPipeline.from_pretrained`] method.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline
|
||||
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Benefits of using the Diffusers-multifolder layout include:
|
||||
|
||||
1. Faster to load each component file individually or in parallel.
|
||||
2. Reduced memory usage because you only load the components you need. For example, models like [SDXL Turbo](https://hf.co/stabilityai/sdxl-turbo), [SDXL Lightning](https://hf.co/ByteDance/SDXL-Lightning), and [Hyper-SD](https://hf.co/ByteDance/Hyper-SD) have the same components except for the UNet. You can reuse their shared components with the [`~DiffusionPipeline.from_pipe`] method without consuming any additional memory (take a look at the [Reuse a pipeline](./loading#reuse-a-pipeline) guide) and only load the UNet. This way, you don't need to download redundant components and unnecessarily use more memory.
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import StableDiffusionXLPipeline, UNet2DConditionModel, EulerDiscreteScheduler
|
||||
|
||||
# download one model
|
||||
sdxl_pipeline = StableDiffusionXLPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True,
|
||||
).to("cuda")
|
||||
|
||||
# switch UNet for another model
|
||||
unet = UNet2DConditionModel.from_pretrained(
|
||||
"stabilityai/sdxl-turbo",
|
||||
subfolder="unet",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True
|
||||
)
|
||||
# reuse all the same components in new model except for the UNet
|
||||
turbo_pipeline = StableDiffusionXLPipeline.from_pipe(
|
||||
sdxl_pipeline, unet=unet,
|
||||
).to("cuda")
|
||||
turbo_pipeline.scheduler = EulerDiscreteScheduler.from_config(
|
||||
turbo_pipeline.scheduler.config,
|
||||
timestep+spacing="trailing"
|
||||
)
|
||||
image = turbo_pipeline(
|
||||
"an astronaut riding a unicorn on mars",
|
||||
num_inference_steps=1,
|
||||
guidance_scale=0.0,
|
||||
).images[0]
|
||||
image
|
||||
```
|
||||
|
||||
3. Reduced storage requirements because if a component, such as the SDXL [VAE](https://hf.co/madebyollin/sdxl-vae-fp16-fix), is shared across multiple models, you only need to download and store a single copy of it instead of downloading and storing it multiple times. For 10 SDXL models, this can save ~3.5GB of storage. The storage savings is even greater for newer models like PixArt Sigma, where the [text encoder](https://hf.co/PixArt-alpha/PixArt-Sigma-XL-2-1024-MS/tree/main/text_encoder) alone is ~19GB!
|
||||
4. Flexibility to replace a component in the model with a newer or better version.
|
||||
|
||||
```py
|
||||
from diffusers import DiffusionPipeline, AutoencoderKL
|
||||
|
||||
vae = AutoencoderKL.from_pretrained("madebyollin/sdxl-vae-fp16-fix", torch_dtype=torch.float16, use_safetensors=True)
|
||||
pipeline = DiffusionPipeline.from_pretrained(
|
||||
"stabilityai/stable-diffusion-xl-base-1.0",
|
||||
vae=vae,
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
5. More visibility and information about a model's components, which are stored in a [config.json](https://hf.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/unet/config.json) file in each component subfolder.
|
||||
|
||||
### Single-file
|
||||
|
||||
The single-file layout stores all the model weights in a single file. All the model components (text encoder, UNet, VAE) weights are kept together instead of separately in subfolders. This can be a safetensors or ckpt file.
|
||||
|
||||
<div class="flex justify-center">
|
||||
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/single-file-layout.png"/>
|
||||
</div>
|
||||
|
||||
To load from a single-file layout, use the [`~loaders.FromSingleFileMixin.from_single_file`] method.
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(
|
||||
"https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0.safetensors",
|
||||
torch_dtype=torch.float16,
|
||||
variant="fp16",
|
||||
use_safetensors=True,
|
||||
).to("cuda")
|
||||
```
|
||||
|
||||
Benefits of using a single-file layout include:
|
||||
|
||||
1. Easy compatibility with diffusion interfaces such as [ComfyUI](https://github.com/comfyanonymous/ComfyUI) or [Automatic1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui) which commonly use a single-file layout.
|
||||
2. Easier to manage (download and share) a single file.
|
||||
|
||||
## Convert layout and files
|
||||
|
||||
Diffusers provides many scripts and methods to convert storage layouts and file formats to enable broader support across the diffusion ecosystem.
|
||||
|
||||
Take a look at the [diffusers/scripts](https://github.com/huggingface/diffusers/tree/main/scripts) collection to find a script that fits your conversion needs.
|
||||
|
||||
> [!TIP]
|
||||
> Scripts that have "`to_diffusers`" appended at the end mean they convert a model to the Diffusers-multifolder layout. Each script has their own specific set of arguments for configuring the conversion, so make sure you check what arguments are available!
|
||||
|
||||
For example, to convert a Stable Diffusion XL model stored in Diffusers-multifolder layout to a single-file layout, run the [convert_diffusers_to_original_sdxl.py](https://github.com/huggingface/diffusers/blob/main/scripts/convert_diffusers_to_original_sdxl.py) script. Provide the path to the model to convert, and the path to save the converted model to. You can optionally specify whether you want to save the model as a safetensors file and whether to save the model in half-precision.
|
||||
|
||||
```bash
|
||||
python convert_diffusers_to_original_sdxl.py --model_path path/to/model/to/convert --checkpoint_path path/to/save/model/to --use_safetensors
|
||||
```
|
||||
|
||||
You can also save a model to Diffusers-multifolder layout with the [`~DiffusionPipeline.save_pretrained`] method. This creates a directory for you if it doesn't already exist, and it also saves the files as a safetensors file by default.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(
|
||||
"https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0.safetensors",
|
||||
)
|
||||
pipeline.save_pretrained()
|
||||
```
|
||||
|
||||
Lastly, there are also Spaces, such as [SD To Diffusers](https://hf.co/spaces/diffusers/sd-to-diffusers) and [SD-XL To Diffusers](https://hf.co/spaces/diffusers/sdxl-to-diffusers), that provide a more user-friendly interface for converting models to Diffusers-multifolder layout. This is the easiest and most convenient option for converting layouts, and it'll open a PR on your model repository with the converted files. However, this option is not as reliable as running a script, and the Space may fail for more complicated models.
|
||||
|
||||
## Single-file layout usage
|
||||
|
||||
Now that you're familiar with the differences between the Diffusers-multifolder and single-file layout, this section shows you how to load models and pipeline components, customize configuration options for loading, and load local files with the [`~loaders.FromSingleFileMixin.from_single_file`] method.
|
||||
|
||||
### Load a pipeline or model
|
||||
|
||||
Pass the file path of the pipeline or model to the [`~loaders.FromSingleFileMixin.from_single_file`] method to load it.
|
||||
|
||||
<hfoptions id="pipeline-model">
|
||||
<hfoption id="pipeline">
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safetensors"
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(ckpt_path)
|
||||
```
|
||||
|
||||
</hfoption>
|
||||
<hfoption id="model">
|
||||
|
||||
```py
|
||||
from diffusers import StableCascadeUNet
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/stable-cascade/blob/main/stage_b_lite.safetensors"
|
||||
model = StableCascadeUNet.from_single_file(ckpt_path)
|
||||
```
|
||||
|
||||
</hfoption>
|
||||
</hfoptions>
|
||||
|
||||
Customize components in the pipeline by passing them directly to the [`~loaders.FromSingleFileMixin.from_single_file`] method. For example, you can use a different scheduler in a pipeline.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline, DDIMScheduler
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safetensors"
|
||||
scheduler = DDIMScheduler()
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(ckpt_path, scheduler=scheduler)
|
||||
```
|
||||
|
||||
Or you could use a ControlNet model in the pipeline.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionControlNetPipeline, ControlNetModel
|
||||
|
||||
ckpt_path = "https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/v1-5-pruned-emaonly.safetensors"
|
||||
controlnet = ControlNetModel.from_pretrained("lllyasviel/control_v11p_sd15_canny")
|
||||
pipeline = StableDiffusionControlNetPipeline.from_single_file(ckpt_path, controlnet=controlnet)
|
||||
```
|
||||
|
||||
### Customize configuration options
|
||||
|
||||
Models have a configuration file that define their attributes like the number of inputs in a UNet. Pipelines configuration options are available in the pipeline's class. For example, if you look at the [`StableDiffusionXLInstructPix2PixPipeline`] class, there is an option to scale the image latents with the `is_cosxl_edit` parameter.
|
||||
|
||||
These configuration files can be found in the models Hub repository or another location from which the configuration file originated (for example, a GitHub repository or locally on your device).
|
||||
|
||||
<hfoptions id="config-file">
|
||||
<hfoption id="Hub configuration file">
|
||||
|
||||
> [!TIP]
|
||||
> The [`~loaders.FromSingleFileMixin.from_single_file`] method automatically maps the checkpoint to the appropriate model repository, but there are cases where it is useful to use the `config` parameter. For example, if the model components in the checkpoint are different from the original checkpoint or if a checkpoint doesn't have the necessary metadata to correctly determine the configuration to use for the pipeline.
|
||||
|
||||
The [`~loaders.FromSingleFileMixin.from_single_file`] method automatically determines the configuration to use from the configuration file in the model repository. You could also explicitly specify the configuration to use by providing the repository id to the `config` parameter.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
|
||||
ckpt_path = "https://huggingface.co/segmind/SSD-1B/blob/main/SSD-1B.safetensors"
|
||||
repo_id = "segmind/SSD-1B"
|
||||
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(ckpt_path, config=repo_id)
|
||||
```
|
||||
|
||||
The model loads the configuration file for the [UNet](https://huggingface.co/segmind/SSD-1B/blob/main/unet/config.json), [VAE](https://huggingface.co/segmind/SSD-1B/blob/main/vae/config.json), and [text encoder](https://huggingface.co/segmind/SSD-1B/blob/main/text_encoder/config.json) from their respective subfolders in the repository.
|
||||
|
||||
</hfoption>
|
||||
<hfoption id="original configuration file">
|
||||
|
||||
The [`~loaders.FromSingleFileMixin.from_single_file`] method can also load the original configuration file of a pipeline that is stored elsewhere. Pass a local path or URL of the original configuration file to the `original_config` parameter.
|
||||
|
||||
```py
|
||||
from diffusers import StableDiffusionXLPipeline
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safetensors"
|
||||
original_config = "https://raw.githubusercontent.com/Stability-AI/generative-models/main/configs/inference/sd_xl_base.yaml"
|
||||
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(ckpt_path, original_config=original_config)
|
||||
```
|
||||
|
||||
> [!TIP]
|
||||
> Diffusers attempts to infer the pipeline components based on the type signatures of the pipeline class when you use `original_config` with `local_files_only=True`, instead of fetching the configuration files from the model repository on the Hub. This prevents backward breaking changes in code that can't connect to the internet to fetch the necessary configuration files.
|
||||
>
|
||||
> This is not as reliable as providing a path to a local model repository with the `config` parameter, and might lead to errors during pipeline configuration. To avoid errors, run the pipeline with `local_files_only=False` once to download the appropriate pipeline configuration files to the local cache.
|
||||
|
||||
</hfoption>
|
||||
</hfoptions>
|
||||
|
||||
While the configuration files specify the pipeline or models default parameters, you can override them by providing the parameters directly to the [`~loaders.FromSingleFileMixin.from_single_file`] method. Any parameter supported by the model or pipeline class can be configured in this way.
|
||||
|
||||
<hfoptions id="override">
|
||||
<hfoption id="pipeline">
|
||||
|
||||
For example, to scale the image latents in [`StableDiffusionXLInstructPix2PixPipeline`] pass the `is_cosxl_edit` parameter.
|
||||
|
||||
```python
|
||||
from diffusers import StableDiffusionXLInstructPix2PixPipeline
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/cosxl/blob/main/cosxl_edit.safetensors"
|
||||
pipeline = StableDiffusionXLInstructPix2PixPipeline.from_single_file(ckpt_path, config="diffusers/sdxl-instructpix2pix-768", is_cosxl_edit=True)
|
||||
```
|
||||
|
||||
</hfoption>
|
||||
<hfoption id="model">
|
||||
|
||||
For example, to upcast the attention dimensions in a [`UNet2DConditionModel`] pass the `upcast_attention` parameter.
|
||||
|
||||
```python
|
||||
from diffusers import UNet2DConditionModel
|
||||
|
||||
ckpt_path = "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safetensors"
|
||||
model = UNet2DConditionModel.from_single_file(ckpt_path, upcast_attention=True)
|
||||
```
|
||||
|
||||
</hfoption>
|
||||
</hfoptions>
|
||||
|
||||
### Local files
|
||||
|
||||
In Diffusers>=v0.28.0, the [`~loaders.FromSingleFileMixin.from_single_file`] method attempts to configure a pipeline or model by inferring the model type from the keys in the checkpoint file. The inferred model type is used to determine the appropriate model repository on the Hugging Face Hub to configure the model or pipeline.
|
||||
|
||||
For example, any single file checkpoint based on the Stable Diffusion XL base model will use the [stabilityai/stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) model repository to configure the pipeline.
|
||||
|
||||
But if you're working in an environment with restricted internet access, you should download the configuration files with the [`~huggingface_hub.snapshot_download`] function, and the model checkpoint with the [`~huggingface_hub.hf_hub_download`] function. By default, these files are downloaded to the Hugging Face Hub [cache directory](https://huggingface.co/docs/huggingface_hub/en/guides/manage-cache), but you can specify a preferred directory to download the files to with the `local_dir` parameter.
|
||||
|
||||
Pass the configuration and checkpoint paths to the [`~loaders.FromSingleFileMixin.from_single_file`] method to load locally.
|
||||
|
||||
<hfoptions id="local">
|
||||
<hfoption id="Hub cache directory">
|
||||
|
||||
```python
|
||||
from huggingface_hub import hf_hub_download, snapshot_download

my_local_checkpoint_path = hf_hub_download(

)
|

|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(my_local_checkpoint_path, config=my_local_config_path, local_files_only=True)

|

#### Local files without symlink
|
||||
|
||||
> [!TIP]
|
||||
> In huggingface_hub>=v0.23.0, the `local_dir_use_symlinks` argument isn't necessary for the [`~huggingface_hub.hf_hub_download`] and [`~huggingface_hub.snapshot_download`] functions.
|
||||
|
||||
The [`~loaders.FromSingleFileMixin.from_single_file`] method relies on the [huggingface_hub](https://hf.co/docs/huggingface_hub/index) caching mechanism to fetch and store checkpoints and configuration files for models and pipelines. If you're working with a file system that does not support symlinking, you should download the checkpoint file to a local directory first, and disable symlinking with the `local_dir_use_symlink=False` parameter in the [`~huggingface_hub.hf_hub_download`] function and [`~huggingface_hub.snapshot_download`] functions.
|
||||
|
||||
```python
|
||||
from huggingface_hub import hf_hub_download, snapshot_download
|
||||
|
||||
my_local_checkpoint_path = hf_hub_download(
|
||||
repo_id="segmind/SSD-1B",
|
||||
filename="SSD-1B.safetensors"
|
||||
local_dir="my_local_checkpoints",
|
||||
local_dir_use_symlinks=False
|
||||
)
|
||||
print("My local checkpoint: ", my_local_checkpoint_path)
|
||||
|
||||
my_local_config_path = snapshot_download(
|
||||
repo_id="segmind/SSD-1B",
|
||||
allowed_patterns=["*.json", "**/*.json", "*.txt", "**/*.txt"]
|
||||
local_dir_use_symlinks=False,
|
||||
)
|
||||
print("My local config: ", my_local_config_path)
|
||||
|
||||
```
|
||||
|
||||
Then you can pass the local paths to the `pretrained_model_link_or_path` and `config` parameters.
|
||||
|
||||
```python
|
||||
pipeline = StableDiffusionXLPipeline.from_single_file(my_local_checkpoint_path, config=my_local_config_path, local_files_only=True)
|
||||
```

# Overview
|
||||
|
||||
The inference pipeline supports and enables a wide range of techniques that are divided into two categories:
|
||||
|
||||
* Pipeline functionality: these techniques modify the pipeline or extend it for other applications. For example, pipeline callbacks add new features to a pipeline and a pipeline can also be extended for distributed inference.
|
||||
* Improve inference quality: these techniques increase the visual quality of the generated images. For example, you can enhance your prompts with GPT2 to create better images with lower effort.

# Overview
|
||||
|
||||
A pipeline is an end-to-end class that provides a quick and easy way to use a diffusion system for inference by bundling independently trained models and schedulers together. Certain combinations of models and schedulers define specific pipeline types, like [`StableDiffusionXLPipeline`] or [`StableDiffusionControlNetPipeline`], with specific capabilities. All pipeline types inherit from the base [`DiffusionPipeline`] class; pass it any checkpoint, and it'll automatically detect the pipeline type and load the necessary components.
|
||||
|
||||
This section demonstrates how to use specific pipelines such as Stable Diffusion XL, ControlNet, and DiffEdit. You'll also learn how to use a distilled version of the Stable Diffusion model to speed up inference, how to create reproducible pipelines, and how to use and contribute community pipelines.

# Create reproducible pipelines
|
||||
|
||||
[[open-in-colab]]
|
||||
|
||||
Reproducibility is important for testing, replicating results, and can even be used to [improve image quality](reusing_seeds). However, the randomness in diffusion models is a desired property because it allows the pipeline to generate different images every time it is run. While you can't expect to get the exact same results across platforms, you can expect results to be reproducible across releases and platforms within a certain tolerance range. Even then, tolerance varies depending on the diffusion pipeline and checkpoint.
|
||||
|
||||
This is why it's important to understand how to control sources of randomness in diffusion models or use deterministic algorithms.
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 We strongly recommend reading PyTorch's [statement about reproducibility](https://pytorch.org/docs/stable/notes/randomness.html):
|
||||
|
||||
> Completely reproducible results are not guaranteed across PyTorch releases, individual commits, or different platforms. Furthermore, results may not be reproducible between CPU and GPU executions, even when using identical seeds.
|
||||
|
||||
</Tip>
|
||||
|
||||
## Control randomness
|
||||
|
||||
During inference, pipelines rely heavily on random sampling operations which include creating the
|
||||
Gaussian noise tensors to denoise and adding noise to the scheduling step.
|
||||
|
||||
Take a look at the tensor values in the [`DDIMPipeline`] after two inference steps:
|
||||
|
||||
```python
|
||||
from diffusers import DDIMPipeline
|
||||
import numpy as np
|
||||
|
||||
model_id = "google/ddpm-cifar10-32"
|
||||
|
||||
# load model and scheduler
|
||||
ddim = DDIMPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
|
||||
# run pipeline for just two steps and return numpy tensor
|
||||
image = ddim(num_inference_steps=2, output_type="np").images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
Running the code above prints one value, but if you run it again you get a different value. What is going on here?
|
||||
|
||||
Every time the pipeline is run, [`torch.randn`](https://pytorch.org/docs/stable/generated/torch.randn.html) uses a different random seed to create Gaussian noise which is denoised stepwise. This leads to a different result each time it is run, which is great for diffusion pipelines since it generates a different random image each time.
|
||||
|
||||
But if you need to reliably generate the same image, that'll depend on whether you're running the pipeline on a CPU or GPU.
|
||||
|
||||
### CPU
|
||||
|
||||
To generate reproducible results on a CPU, you'll need to use a PyTorch [`Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) and set a seed:
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import DDIMPipeline
|
||||
import numpy as np
|
||||
|
||||
model_id = "google/ddpm-cifar10-32"
|
||||
|
||||
# load model and scheduler
|
||||
ddim = DDIMPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
|
||||
# create a generator for reproducibility
|
||||
generator = torch.Generator(device="cpu").manual_seed(0)
|
||||
|
||||
# run pipeline for just two steps and return numpy tensor
|
||||
image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
Now when you run the code above, it always prints a value of `1491.1711` no matter what because the `Generator` object with the seed is passed to all the random functions of the pipeline.
|
||||
|
||||
If you run this code example on your specific hardware and PyTorch version, you should get a similar, if not the same, result.
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 It might be a bit unintuitive at first to pass `Generator` objects to the pipeline instead of
|
||||
just integer values representing the seed, but this is the recommended design when dealing with
|
||||
probabilistic models in PyTorch, as `Generator`s are *random states* that can be
|
||||
passed to multiple pipelines in a sequence.
|
||||
|
||||
</Tip>
|
||||
|
||||
### GPU
|
||||
|
||||
Writing a reproducible pipeline on a GPU is a bit trickier, and full reproducibility across different hardware is not guaranteed because matrix multiplication - which diffusion pipelines require a lot of - is less deterministic on a GPU than a CPU. For example, if you run the same code example above on a GPU:
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import DDIMPipeline
|
||||
import numpy as np
|
||||
|
||||
model_id = "google/ddpm-cifar10-32"
|
||||
|
||||
# load model and scheduler
|
||||
ddim = DDIMPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
ddim.to("cuda")
|
||||
|
||||
# create a generator for reproducibility
|
||||
generator = torch.Generator(device="cuda").manual_seed(0)
|
||||
|
||||
# run pipeline for just two steps and return numpy tensor
|
||||
image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
The result is not the same even though you're using an identical seed because the GPU uses a different random number generator than the CPU.
|
||||
|
||||
To circumvent this problem, 🧨 Diffusers has a [`~diffusers.utils.torch_utils.randn_tensor`] function for creating random noise on the CPU, and then moving the tensor to a GPU if necessary. The `randn_tensor` function is used everywhere inside the pipeline, allowing the user to **always** pass a CPU `Generator` even if the pipeline is run on a GPU.
|
||||
|
||||
You'll see the results are much closer now!
|
||||
|
||||
```python
|
||||
import torch
|
||||
from diffusers import DDIMPipeline
|
||||
import numpy as np
|
||||
|
||||
model_id = "google/ddpm-cifar10-32"
|
||||
|
||||
# load model and scheduler
|
||||
ddim = DDIMPipeline.from_pretrained(model_id, use_safetensors=True)
|
||||
ddim.to("cuda")
|
||||
|
||||
# create a generator for reproducibility; notice you don't place it on the GPU!
|
||||
generator = torch.manual_seed(0)
|
||||
|
||||
# run pipeline for just two steps and return numpy tensor
|
||||
image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
<Tip>
|
||||
|
||||
💡 If reproducibility is important, we recommend always passing a CPU generator.
|
||||
The performance loss is often neglectable, and you'll generate much more similar
|
||||
values than if the pipeline had been run on a GPU.
|
||||
|
||||
</Tip>
|
||||
|
||||
Finally, for more complex pipelines such as [`UnCLIPPipeline`], these are often extremely
|
||||
susceptible to precision error propagation. Don't expect similar results across
|
||||
different GPU hardware or PyTorch versions. In this case, you'll need to run
|
||||
exactly the same hardware and PyTorch version for full reproducibility.
|
||||
|
||||
## Deterministic algorithms
|
||||
|
||||
You can also configure PyTorch to use deterministic algorithms to create a reproducible pipeline. However, you should be aware that deterministic algorithms may be slower than nondeterministic ones and you may observe a decrease in performance. But if reproducibility is important to you, then this is the way to go!
|
||||
|
||||
Nondeterministic behavior occurs when operations are launched in more than one CUDA stream. To avoid this, set the environment variable [`CUBLAS_WORKSPACE_CONFIG`](https://docs.nvidia.com/cuda/cublas/index.html#results-reproducibility) to `:16:8` to only use one buffer size during runtime.
|
||||
|
||||
PyTorch typically benchmarks multiple algorithms to select the fastest one, but if you want reproducibility, you should disable this feature because the benchmark may select different algorithms each time. Lastly, pass `True` to [`torch.use_deterministic_algorithms`](https://pytorch.org/docs/stable/generated/torch.use_deterministic_algorithms.html) to enable deterministic algorithms.
|
||||
|
||||
```py
|
||||
import os
|
||||
import torch
|
||||
|
||||
os.environ["CUBLAS_WORKSPACE_CONFIG"] = ":16:8"
|
||||
|
||||
torch.backends.cudnn.benchmark = False
|
||||
torch.use_deterministic_algorithms(True)
|
||||
```
|
||||
|
||||
Now when you run the same pipeline twice, you'll get identical results.
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import DDIMScheduler, StableDiffusionPipeline
|
||||
|
||||
model_id = "runwayml/stable-diffusion-v1-5"
|
||||
pipe = StableDiffusionPipeline.from_pretrained(model_id, use_safetensors=True).to("cuda")
|
||||
pipe.scheduler = DDIMScheduler.from_config(pipe.scheduler.config)
|
||||
g = torch.Generator(device="cuda")
|
||||

||||

|
||||
result2 = pipe(prompt=prompt, num_inference_steps=50, generator=g, output_type="latent").images
|
||||
|
||||
print("L_inf dist =", abs(result1 - result2).max())
|
||||
"L_inf dist = tensor(0., device='cuda:0')"

|
||||
Diffusion models are inherently random which is what allows it to generate different outputs every time it is run. But there are certain times when you want to generate the same output every time, like when you're testing, replicating results, and even [improving image quality](#deterministic-batch-generation). While you can't expect to get identical results across platforms, you can expect reproducible results across releases and platforms within a certain tolerance range (though even this may vary).
|
||||
|
||||
A common way to improve the quality of generated images is with *deterministic batch generation*, generate a batch of images and select one image to improve with a more detailed prompt in a second round of inference. The key is to pass a list of [`torch.Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html#generator)'s to the pipeline for batched image generation, and tie each `Generator` to a seed so you can reuse it for an image.
|
||||
This guide will show you how to control randomness for deterministic generation on a CPU and GPU.
|
||||
|
||||
Let's use [`runwayml/stable-diffusion-v1-5`](https://huggingface.co/runwayml/stable-diffusion-v1-5) for example, and generate several versions of the following prompt:
|
||||
> [!TIP]
|
||||
> We strongly recommend reading PyTorch's [statement about reproducibility](https://pytorch.org/docs/stable/notes/randomness.html):
|
||||
>
|
||||
> "Completely reproducible results are not guaranteed across PyTorch releases, individual commits, or different platforms. Furthermore, results may not be reproducible between CPU and GPU executions, even when using identical seeds."
|
||||
|
||||
```py
|
||||
prompt = "Labrador in the style of Vermeer"
|
||||
```
|
||||
## Control randomness
|
||||
|
||||
Instantiate a pipeline with [`DiffusionPipeline.from_pretrained`] and place it on a GPU (if available):
|
||||
During inference, pipelines rely heavily on random sampling operations which include creating the
|
||||
Gaussian noise tensors to denoise and adding noise to the scheduling step.
|
||||
|
||||
Take a look at the tensor values in the [`DDIMPipeline`] after two inference steps.
|
||||
|
||||
```python
|
||||
from diffusers import DDIMPipeline
|
||||
import numpy as np
|
||||
|
||||
ddim = DDIMPipeline.from_pretrained( "google/ddpm-cifar10-32", use_safetensors=True)
|
||||
image = ddim(num_inference_steps=2, output_type="np").images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
Running the code above prints one value, but if you run it again you get a different value.
|
||||
|
||||
Each time the pipeline is run, [torch.randn](https://pytorch.org/docs/stable/generated/torch.randn.html) uses a different random seed to create the Gaussian noise tensors. This leads to a different result each time it is run and enables the diffusion pipeline to generate a different random image each time.
|
||||
|
||||
But if you need to reliably generate the same image, that depends on whether you're running the pipeline on a CPU or GPU.
|
||||
|
||||
> [!TIP]
|
||||
> It might seem unintuitive to pass `Generator` objects to a pipeline instead of the integer value representing the seed. However, this is the recommended design when working with probabilistic models in PyTorch because a `Generator` is a *random state* that can be passed to multiple pipelines in a sequence. As soon as the `Generator` is consumed, the *state* is changed in place which means even if you passed the same `Generator` to a different pipeline, it won't produce the same result because the state is already changed.

Now when you run the code, it always prints a value of `1491.1711` because the `Generator` object with the seed is passed to all the random functions in the pipeline. You should get a similar, if not the same, result on whatever hardware and PyTorch version you're using.

image = ddim(num_inference_steps=2, output_type="np", generator=generator).images

print(np.abs(image).sum())

<hfoption id="GPU">
|
||||
|
||||
Writing a reproducible pipeline on a GPU is a bit trickier, and full reproducibility across different hardware is not guaranteed because matrix multiplication - which diffusion pipelines require a lot of - is less deterministic on a GPU than a CPU. For example, if you run the same code example from the CPU example, you'll get a different result even though the seed is identical. This is because the GPU uses a different random number generator than the CPU.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import numpy as np
|
||||
from diffusers import DDIMPipeline
|
||||
|
||||
ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
|
||||
ddim.to("cuda")
|
||||
generator = torch.Generator(device="cuda").manual_seed(0)
|
||||
image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
To avoid this issue, Diffusers has a [`~utils.torch_utils.randn_tensor`] function for creating random noise on the CPU, and then moving the tensor to a GPU if necessary. The [`~utils.torch_utils.randn_tensor`] function is used everywhere inside the pipeline. Now you can call [torch.manual_seed](https://pytorch.org/docs/stable/generated/torch.manual_seed.html) which automatically creates a CPU `Generator` that can be passed to the pipeline even if it is being run on a GPU.
|
||||
|
||||
```python
|
||||
import torch
|
||||
import numpy as np
|
||||
from diffusers import DDIMPipeline
|
||||
|
||||
ddim = DDIMPipeline.from_pretrained("google/ddpm-cifar10-32", use_safetensors=True)
|
||||
ddim.to("cuda")
|
||||
generator = torch.manual_seed(0)
|
||||
image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
|
||||
print(np.abs(image).sum())
|
||||
```
|
||||
|
||||
> [!TIP]
|
||||
> If reproducibility is important to your use case, we recommend always passing a CPU `Generator`. The performance loss is often negligible and you'll generate more similar values than if the pipeline had been run on a GPU.
|
||||
|
||||
Finally, more complex pipelines such as [`UnCLIPPipeline`], are often extremely
|
||||
susceptible to precision error propagation. You'll need to use
|
||||
exactly the same hardware and PyTorch version for full reproducibility.

||||
|
||||

||||
## Deterministic algorithms
|
||||
|
||||
You can also configure PyTorch to use deterministic algorithms to create a reproducible pipeline. The downside is that deterministic algorithms may be slower than non-deterministic ones and you may observe a decrease in performance.
|
||||
|
||||
Non-deterministic behavior occurs when operations are launched in more than one CUDA stream. To avoid this, set the environment variable [CUBLAS_WORKSPACE_CONFIG](https://docs.nvidia.com/cuda/cublas/index.html#results-reproducibility) to `:16:8` to only use one buffer size during runtime.
|
||||
|
||||
PyTorch typically benchmarks multiple algorithms to select the fastest one, but if you want reproducibility, you should disable this feature because the benchmark may select different algorithms each time. Set Diffusers [enable_full_determinism](https://github.com/huggingface/diffusers/blob/142f353e1c638ff1d20bd798402b68f72c1ebbdd/src/diffusers/utils/testing_utils.py#L861) to enable deterministic algorithms.
|
||||
|
||||
```py
|
||||
enable_full_determinism()
|
||||
```
|
||||
|
||||
Now when you run the same pipeline twice, you'll get identical results.
|
||||
|
||||
```py
|
||||
import torch
|
||||
from diffusers import DDIMScheduler, StableDiffusionPipeline
|
||||
|
||||
pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", use_safetensors=True).to("cuda")
|
||||
pipe.scheduler = DDIMScheduler.from_config(pipe.scheduler.config)
|
||||
g = torch.Generator(device="cuda")
|
||||
|
||||
prompt = "A bear is playing a guitar on Times Square"
|
||||
|
||||
g.manual_seed(0)
|
||||
result1 = pipe(prompt=prompt, num_inference_steps=50, generator=g, output_type="latent").images
|
||||
|
||||
g.manual_seed(0)
|
||||
result2 = pipe(prompt=prompt, num_inference_steps=50, generator=g, output_type="latent").images
|
||||
|
||||
print("L_inf dist =", abs(result1 - result2).max())
|
||||
"L_inf dist = tensor(0., device='cuda:0')"
|
||||
```
|
||||
|
||||
## Deterministic batch generation
|
||||
|
||||
A practical application of creating reproducible pipelines is *deterministic batch generation*. You generate a batch of images and select one image to improve with a more detailed prompt. The main idea is to pass a list of [Generator's](https://pytorch.org/docs/stable/generated/torch.Generator.html) to the pipeline and tie each `Generator` to a seed so you can reuse it.
|
||||
|
||||
Let's use the [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) checkpoint and generate a batch of images.
|
||||
|
||||
```py

Now, define four different `Generator`s and assign each `Generator` a seed (`0` to `3`) so you can reuse a `Generator` later for a specific image:

Define four different `Generator`s and assign each `Generator` a seed (`0` to `3`). Then generate a batch of images and pick one to iterate on.

> [!WARNING]
|
||||
> Use a list comprehension that iterates over the batch size specified in `range()` to create a unique `Generator` object for each image in the batch. If you multiply the `Generator` by the batch size integer, it only creates *one* `Generator` object that is used sequentially for each image in the batch.

|

|

To create a batched seed, you should use a list comprehension that iterates over the length specified in `range()`. This creates a unique `Generator` object for each image in the batch. If you only multiply the `Generator` by the batch size, this only creates one `Generator` object that is used sequentially for each image in the batch.
|
||||
|
||||
For example, if you want to use the same seed to create 4 identical images:
|
||||
|
||||
```py
|
||||
❌ [torch.Generator().manual_seed(seed)] * 4
|
||||
|
||||
✅ [torch.Generator().manual_seed(seed) for _ in range(4)]
|
||||
```
|
||||
|
||||
</Tip>
|
||||
|
||||
Generate the images and have a look:
|
||||
|
||||
```python
|
||||
images = pipe(prompt, generator=generator, num_images_per_prompt=4).images
|
||||
prompt = "Labrador in the style of Vermeer"
|
||||
images = pipeline(prompt, generator=generator, num_images_per_prompt=4).images[0]
|
||||
make_image_grid(images, rows=2, cols=2)
|
||||
```

In this example, you'll improve upon the first image - but in reality, you can use any image you want (even the image with double sets of eyes!). The first image used the `Generator` with seed `0`, so you'll reuse that `Generator` for the second round of inference. To improve the quality of the image, add some additional text to the prompt:
|
||||
Let's improve the first image (you can choose any image you want) which corresponds to the `Generator` with seed `0`. Add some additional text to your prompt and then make sure you reuse the same `Generator` with seed `0`. All the generated images should resemble the first image.
|
||||
|
||||
```python
|
||||
prompt = [prompt + t for t in [", highly realistic", ", artsy", ", trending", ", colorful"]]
|
||||
generator = [torch.Generator(device="cuda").manual_seed(0) for i in range(4)]
|
||||
```
|
||||
|
||||
Create four generators with seed `0`, and generate another batch of images, all of which should look like the first image from the previous round!
|
||||
|
||||
```python
|
||||
images = pipe(prompt, generator=generator).images
|
||||
images = pipeline(prompt, generator=generator).images
|
||||
make_image_grid(images, rows=2, cols=2)
|
