Logging

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.

Copied

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:

Copied

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:

Copied

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:

Copied

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

<source>

( )

Set the verbosity to the ERROR level.

diffusers.utils.logging.set_verbosity_warning

<source>

( )

Set the verbosity to the WARNING level.

diffusers.utils.logging.set_verbosity_info

<source>

( )

Set the verbosity to the INFO level.

diffusers.utils.logging.set_verbosity_debug

<source>

( )

Set the verbosity to the DEBUG level.

Other functions

diffusers.utils.logging.get_verbosity

<source>

( ) → 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

Return the current level for the 🌍 Diffusers’ root logger as an int.

diffusers.utils.logging.set_verbosity

<source>

( verbosity: int )

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

Set the verbosity level for the 🌍 Diffusers’ root logger.

diffusers.utils.get_logger

<source>

( name: typing.Optional[str] = None )

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

<source>

( )

Enable the default handler of the 🌍 Diffusers’ root logger.

diffusers.utils.logging.disable_default_handler

<source>

( )

Disable the default handler of the 🌍 Diffusers’ root logger.

diffusers.utils.logging.enable_explicit_format

<source>

( )

Enable explicit formatting for every 🌍 Diffusers’ logger. The explicit formatter is as follows:

Copied

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

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

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

<source>

( )

Enable tqdm progress bar.

diffusers.utils.logging.disable_progress_bar

<source>

( )

Disable tqdm progress bar.
