      """Initialize and get a logger by name.
      If the logger has not been initialized, this method will initialize the
      logger by adding one or two handlers, otherwise the initialized logger will
      be directly returned. During initialization, a StreamHandler will always be
      added. If `log_file` is specified a FileHandler will also be added.
      Args:
          name (str): Logger name.
          log_file (str | None): The log filename. If specified, a FileHandler
              will be added to the logger.
          log_level (int): The logger level. Note that only the process of
              rank 0 is affected, and other processes will set the level to
              "Error" thus be silent most of the time.
      Returns:
          logging.Logger: The expected logger.
