Logging
🤗 Transformers has a centralized logging system, so that you can setup the verbosity of the library easily.
Currently the default verbosity of the library is WARNING
.
To change the level of verbosity, just use one of the direct setters. For instance, here is how to change the verbosity to the INFO level.
import transformers
transformers.logging.set_verbosity_info()
You can also use the environment variable TRANSFORMERS_VERBOSITY
to override the default verbosity. You can set it
to one of the following: debug
, info
, warning
, error
, critical
. For example:
TRANSFORMERS_VERBOSITY=error ./myprogram.py
All the methods of this logging module are documented below, the main ones are transformers.logging.get_verbosity() to get the current level of verbosity in the logger and transformers.logging.set_verbosity() to set the verbosity to the level of your choice. In order (from the least verbose to the most verbose), those levels (with their corresponding int values in parenthesis) are:
transformers.logging.CRITICAL
ortransformers.logging.FATAL
(int value, 50): only report the most critical errors.transformers.logging.ERROR
(int value, 40): only report errors.transformers.logging.WARNING
ortransformers.logging.WARN
(int value, 30): only reports error and warnings. This the default level used by the library.transformers.logging.INFO
(int value, 20): reports error, warnings and basic information.transformers.logging.DEBUG
(int value, 10): report all information.
Base setters
Set the verbosity to the ERROR
level.
Set the verbosity to the WARNING
level.
Set the verbosity to the INFO
level.
Set the verbosity to the DEBUG
level.
Other functions
Return the current level for the 🤗 Transformers’s root logger as an int.
🤗 Transformers has following logging levels:
- 50:
transformers.logging.CRITICAL
ortransformers.logging.FATAL
- 40:
transformers.logging.ERROR
- 30:
transformers.logging.WARNING
ortransformers.logging.WARN
- 20:
transformers.logging.INFO
- 10:
transformers.logging.DEBUG
( verbosity: int )
Set the verbosity level for the 🤗 Transformers’s root logger.
Return a logger with the specified name.
This function is not supposed to be directly accessed unless you are writing a custom transformers module.
Enable the default handler of the HuggingFace Transformers’s root logger.
Disable the default handler of the HuggingFace Transformers’s root logger.
Enable explicit formatting for every HuggingFace Transformers’s 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.
Resets the formatting for HuggingFace Transformers’s loggers.
All handlers currently bound to the root logger are affected by this method.
