Do you meet the error "MGMConfig"?

[strawberryrs620]

I just want to deploy the Mini Gemini LLM, I meet the following error of "MGMConfig", when execute the following command:
python -m mgm.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path work_dirs/MGM/MGM-13B-HD

error:
mode_type=self._reverse_config_mapping[key.name]
KeyError: 'MGMConfig'
