Replacement for add_argparse_args()

Hello, I am new to pytorch-lightning and I have encountered a problem with the stable-diffusion code from MLPerf which seems to use an old version of lightning. So, the problem is, the add_argparse_args is no longer available. I wonder how to migrate this piece of code to the new version.

def get_parser(**parser_kwargs):
    parser = argparse.ArgumentParser(**parser_kwargs)
    parser.add_argument(
        "-n",
        "--name",
        type=str,
        const=True,
        default="",
        nargs="?",
        help="postfix for logdir",
    )
    return parser

if __name__ == "__main__":
    parser = get_parser()
    parser = Trainer.add_argparse_args(parser)
