transformers==4.51.3 is not a correct version

[Dr-Corgi]

Hi @Guangxuan-Xiao ,

Issue description:
It appears that the Qwen2_5-VL and Qwen2_VL modeling code in the transformers package has undergone significant changes.

• earliest version: https://github.com/huggingface/transformers/blob/f3f6c86582611976e72be054675e2bf0abb5f775/src/transformers/models/qwen2_5_vl/modeling_qwen2_5_vl.py
• latest version: https://github.com/huggingface/transformers/blob/main/src/transformers/models/qwen2_5_vl/modeling_qwen2_5_vl.py

With transformers version 4.51.3, several modules used in the language_forward.py and vision_forward.py fail to import correctly.

• https://github.com/mit-han-lab/streaming-vlm/blob/main/streaming_vlm/inference/qwen2_5/language_forward.py#L7
• https://github.com/mit-han-lab/streaming-vlm/blob/main/streaming_vlm/inference/qwen2_5/vision_forward.py#L7

Could you verify which transformers version you are currently using? Thanks!
