I don’t think it’s my issues.
I config logs as bellow.
def get_logger(file_path):
    streamhandler = logging.StreamHandler()
    logger = logging.getLogger('Distribute training logs.')
    logger.setLevel(logging.INFO)
    logger.addHandler(streamhandler)
    return logger

I tried this still has additional logs.
Could you please give some suggests @osalpekar?
