I don’t use PT Lightning. I based my logger setup on https://github.com/directgroup/direct/blob/d1eb9ba8706b25a7aae19b03587cd79cd3675822/direct/environment.py#L78 3, which calls https://github.com/directgroup/direct/blob/d1eb9ba8706b25a7aae19b03587cd79cd3675822/direct/utils/logging.py#L10 4 to setup the logger.
