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.

Base setters[[diffusers.utils.logging.set_verbosity_error]]

diffusers.utils.logging.set_verbosity_error[[diffusers.utils.logging.set_verbosity_error]]

Source

Set the verbosity to the ERROR level.

diffusers.utils.logging.set_verbosity_warning[[diffusers.utils.logging.set_verbosity_warning]]

Source

Set the verbosity to the WARNING level.

diffusers.utils.logging.set_verbosity_info[[diffusers.utils.logging.set_verbosity_info]]

Source

Set the verbosity to the INFO level.

diffusers.utils.logging.set_verbosity_debug[[diffusers.utils.logging.set_verbosity_debug]]

Source

Set the verbosity to the DEBUG level.

Other functions[[diffusers.utils.logging.get_verbosity]]

diffusers.utils.logging.get_verbosity[[diffusers.utils.logging.get_verbosity]]

Source

Return the current level for the 🤗 Diffusers' root logger as an int.

Returns:

int

Logging level integers which can be one of:

• 50: diffusers.logging.CRITICAL or diffusers.logging.FATAL
• 40: diffusers.logging.ERROR
• 30: diffusers.logging.WARNING or diffusers.logging.WARN
• 20: diffusers.logging.INFO
• 10: diffusers.logging.DEBUG

diffusers.utils.logging.set_verbosity[[diffusers.utils.logging.set_verbosity]]

Source

Set the verbosity level for the 🤗 Diffusers' root logger.

Parameters:

verbosity (int) : Logging level which can be one of: - diffusers.logging.CRITICAL or diffusers.logging.FATAL - diffusers.logging.ERROR - diffusers.logging.WARNING or diffusers.logging.WARN - diffusers.logging.INFO - diffusers.logging.DEBUG

diffusers.utils.get_logger[[diffusers.utils.get_logger]]

Source

Return a logger with the specified name.

This function is not supposed to be directly accessed unless you are writing a custom diffusers module.

diffusers.utils.logging.enable_default_handler[[diffusers.utils.logging.enable_default_handler]]

Source

Enable the default handler of the 🤗 Diffusers' root logger.

diffusers.utils.logging.disable_default_handler[[diffusers.utils.logging.disable_default_handler]]

Source

Disable the default handler of the 🤗 Diffusers' root logger.

diffusers.utils.logging.enable_explicit_format[[diffusers.utils.logging.enable_explicit_format]]

Source

Enable explicit formatting for every 🤗 Diffusers' logger. The explicit formatter is as follows:

[LEVELNAME|FILENAME|LINE NUMBER] TIME >> MESSAGE

All handlers currently bound to the root logger are affected by this method.

diffusers.utils.logging.reset_format[[diffusers.utils.logging.reset_format]]

Source

Resets the formatting for 🤗 Diffusers' loggers.

All handlers currently bound to the root logger are affected by this method.

diffusers.utils.logging.enable_progress_bar[[diffusers.utils.logging.enable_progress_bar]]

Source

Enable tqdm progress bar.

diffusers.utils.logging.disable_progress_bar[[diffusers.utils.logging.disable_progress_bar]]

Source

Disable tqdm progress bar.
