[BUG] how to parse the parameters of the respective section using hydra and argparse?

I'm training unet with deepspeed.

The basic trainging code parses parameters through hydra. The simplified code is

@hydra.main(version_base="1.2", config_path="config", config_name="config_rdb")
def main(cfg:DictConfig):
    print(OmegaConf.to_yaml(cfg))
    run_training_Unet(
         if_training=cfg.args.if_training,
         epochs=cfg.args.epochs,
        )

if __name__=="__main__":
    main()

python train.py +args=config.yaml ++args.modename='unet'

I change the basica code to deepseep version.

@hydra.main(version_base="1.2", config_path="config", config_name="config_rdb")
def main(cfg:DictConfig, args,):
    print(OmegaConf.to_yaml(cfg))
    run_training_Unet(
         if_training=cfg.args.if_training,
         epochs=cfg.args.epochs,
         args=args
     )

if __name__=="__main__":
    parser=argparse.ArgumentParser(description='deepspeed')
    parser.add_argument('--deepspeed_config',type=str,default=None,
                           help='Path')
    parser.add_argument('--local_rank',type=int,default=None,
                            help='local rank for deepspeed')
    parser.add_argument('--global_rank', type=int, default=None, 
					help='global rank')
    args=parser.parse_args()
    main(args)

deepspeed train.py +args=config.yaml ++args.modename='unet' --deepspeed --deepspeed_config ds_config.json

But i got a error.

train_models_forward_deepspeed.py: error: unrecognized arguments: --local_rank=0

I think it's the conflict of hydra and argparse parsing parameters. Is there a tutorial code?

Start with the train.py entry point, the @hydra.main function, and the argparse setup shown in the report. Reproduce the DeepSpeed command and its --local_rank=0 error, then compare how Hydra and argparse receive arguments. Done should be a documented, working parameter-parsing pattern or a confirmed correction to the invocation.
