Set the logging level.
str, int, or NoneThe 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.
If True, return the old verbosity level.
int | NoneIf int, enable (>=1) or disable (0) the printing of stack frame information using formatting. Default (None) does not change the formatting. This can add overhead so is meant only for debugging.
intThe old level. Only returned if return_old_level is True.
