👋 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.

Hello @fyabc! We're currently going through re-architecture of vLLM and I'm wondering if it's possible to add M-RoPE into the model file instead of the model runner. Do you have any suggestion?

@fyabc Hello! I closed this PR by accident, but I haven't really made too much progress on Qwen2 VL (mostly I'm not sure if we can put MRoPE inside the model file instead of the model runner) If it makes things easier feel free to join slack.vllm.ai so we can discuss more offline!
