Logging
-------

🤗 Transformers has a centralized logging system, so that you can setup the verbosity of the library easily. 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.

.. code-block:: python

    import transformers
    transformers.logging.set_verbosity_info()

All the methods of this logging module are documented below, the main ones are
:func:`transformers.logging.get_verbosity` to get the current level of verbosity in the logger and
:func:`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:

- :obj:`transformers.logging.CRITICAL` or :obj:`transformers.logging.FATAL` (int value, 50): only report the most
  critical errors.
- :obj:`transformers.logging.ERROR` (int value, 40): only report errors.
- :obj:`transformers.logging.WARNING` or :obj:`transformers.logging.WARN` (int value, 30): only reports error and
  warnings. This the default level used by the library.
- :obj:`transformers.logging.INFO` (int value, 20): reports error, warnings and basic information.
- :obj:`transformers.logging.DEBUG` (int value, 10): report all information.
