Fixes AttributeError when loading GO-1 pretrained checkpoint from HuggingFace. The _init_weights method in modeling_action_expert.py accesses self.config.initializer_range, but GO1ModelConfig did not have this attribute set. Issue: OpenDriveLab#126

Fixes Issue #126
Problem
When loading GO-1 pretrained checkpoint from HuggingFace (agibot-world/GO-1), the model fails during initialization with:
This occurs in
modeling_action_expert.pyline 513, where_init_weightsaccessesself.config.initializer_range, butGO1ModelConfigdid not have this attribute.Solution
Add
initializer_range = 0.02as a default attribute inGO1ModelConfig.__init__.Changes
go1/internvl/model/go1/configuration_go1.py: Addedself.initializer_range = 0.02
