get_logger

get_logger() -> logging.Logger

[view_source]

Get a logging.Logger to stderr. It can be called whenever we wish to log some message. Messages can get mixed-up (https://docs.python.org/3.6/library/multiprocessing.html#logging), but it works well in most cases.

Returns

logger: the logging.Logger object

init_logging

init_logging(human_log_level: str = "info") -> None

[view_source]

Init the logging.Logger.

It should be called only once in the app (e.g. in main). It sets the log_level to one of HUMAN_LOG_LEVELS. And sets up a handler for stderr. The logging level is propagated to all subprocesses.

find_free_port

find_free_port(address: str = "127.0.0.1") -> int

[view_source]

Finds a free port for distributed training.

Returns

port: port number that can be used to listen
