      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.
