👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

  • Add ready label to the PR
  • Enable auto-merge.

🚀

Although vllm currently only supports lora inference for language model, considering that inference for vision modules will be supported in the future, we should also add vision encoder related modules.

However, currently fine-tuning only the language model with LoRA achieves good results and meets the needs of most users. Further optimizations can be made later if necessary.

Yes, I agree with your view. I just think it might be better to complete the additions first. If you're interested, you can refer to Qwen-VL's implementation, see: https://github.com/vllm-project/vllm/blob/main/vllm/model_executor/models/qwen.py#L1015-L1046.

Alternatively, you could add TODO above the supported_lora_modules , indicating that we need to add LoRA for the visual encoder in the future. Additionally, you need to update the documentation to specify that this model supports LoRA.

…sage and update documentation.
