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. .. code-block:: python 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: .. code-block:: bash TRANSFORMERS_VERBOSITY=error ./myprogram.py 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.
