Logging

🤗 Diffusers has a centralized logging system to easily manage the verbosity of the library. The default verbosity is set to WARNING.

To change the verbosity level, use one of the direct setters. For instance, to change the verbosity to the INFO level.

import diffusers

diffusers.logging.set_verbosity_info()

You can also use the environment variable DIFFUSERS_VERBOSITY to override the default verbosity. You can set it to one of the following: debug, info, warning, error, critical. For example:

DIFFUSERS_VERBOSITY=error ./myprogram.py

Additionally, some warnings can be disabled by setting the environment variable DIFFUSERS_NO_ADVISORY_WARNINGS to a true value, like 1. This disables any warning logged by [logger.warning_advice]. For example:

DIFFUSERS_NO_ADVISORY_WARNINGS=1 ./myprogram.py

Here is an example of how to use the same logger as the library in your own module or script:

from diffusers.utils import logging

logging.set_verbosity_info()
logger = logging.get_logger("diffusers")
logger.info("INFO")
logger.warning("WARN")

All methods of the logging module are documented below. The main methods are [logging.get_verbosity] to get the current level of verbosity in the logger and [logging.set_verbosity] to set the verbosity to the level of your choice.

In order from the least verbose to the most verbose:

Method	Integer value	Description
diffusers.logging.CRITICAL or diffusers.logging.FATAL	50	only report the most critical errors
diffusers.logging.ERROR	40	only report errors
diffusers.logging.WARNING or diffusers.logging.WARN	30	only report errors and warnings (default)
diffusers.logging.INFO	20	only report errors, warnings, and basic information
diffusers.logging.DEBUG	10	report all information

By default, tqdm progress bars are displayed during model download. [logging.disable_progress_bar] and [logging.enable_progress_bar] are used to enable or disable this behavior.
