### Simple Solution for InternVL Configuration Issue
*(Tested with transformers v4.52.4)*
#### Required Modifications
1. **Add Initialization** (configuration_internvl_chat.py:49)
```python
self.vision_config = InternVisionConfig(**vision_config)
self.llm_config = None # Initialize llm_config to prevent AttributeError
```
2. **Add Null Check** (configuration_internvl_chat.py:85)
```python
output['llm_config'] = self.llm_config.to_dict() if self.llm_config is not None else {}
```
#### Root Cause Analysis
When executing:
```python
model = AutoModel.from_pretrained(model_path, trust_remote_code=True).half().cuda().to(torch.bfloat16)
```
The following occurs:
