What I've Tried

• I read the Quick start and follow the guide
• since the ray is running in company paltform, and run ray job submit directly and not kill and start

Environment (if relevant)

• slime version:bd70add6ab27e773294081fd260888f003984146

Pre-submission Checklist

• I have read the CONTRIBUTING.md and understand the collaboration scope.
• I have read the documentation and FAQ and my question is not answered there.
• I have searched for existing issues and my question has not been asked before.

Start at slime/slime_plugins/models/glm4.py in get_glm_spec, then trace how the Namespace is built through slime/backends/megatron_utils/model_provider.py and the model setup path. Reproduce the reported failure at commit bd70add6ab27e773294081fd260888f003984146 and determine how the missing argument is expected to be supplied. Done means GLM4 model initialization reaches completion without this AttributeError.
