    """Get the root logger.

    The logger will be initialized if it has not been initialized. By default a

    StreamHandler will be added. If `log_file` is specified, a FileHandler will

    also be added. The name of the root logger is the top-level package name,

    e.g., "mmseg".

    Args:

        log_file (str | None): The log filename. If specified, a FileHandler

            will be added to the root logger.

        log_level (int): The root logger level. Note that only the process of

            rank 0 is affected, while other processes will set the level to

            "Error" and be silent most of the time.

    Returns:

        logging.Logger: The root logger.
