Dependency conflicts for `vllm`

According to [requirements.txt](https://github.com/deepseek-ai/DeepSeek-OCR/blob/main/requirements.txt), this project requires `transformers==4.46.3` and `tokenizers==0.20.3`.

However, `vllm 0.8.5` -- the version suggested by the official [README](https://github.com/deepseek-ai/DeepSeek-OCR/#install) -- requires `transformers >= 4.51.1` and `tokenizers >= 0.21.1` according to its [requirements](https://github.com/vllm-project/vllm/blob/v0.8.5/requirements/common.txt).

Hence there are dependency conflicts. Could you provide a solution or a workaround? Downgrade `vllm`, change `requirements.txt`, or simply ignore the conflicts?
