mne.set_log_level(verbose=None, return_old_level=False)[source]

Set the logging level.


verbose : bool, str, int, or None

The verbosity of messages to print. If a str, it can be either DEBUG, INFO, WARNING, ERROR, or CRITICAL. Note that these are for convenience and are equivalent to passing in logging.DEBUG, etc. For bool, True is the same as ‘INFO’, False is the same as ‘WARNING’. If None, the environment variable MNE_LOGGING_LEVEL is read, and if it doesn’t exist, defaults to INFO.

return_old_level : bool

If True, return the old verbosity level.
