👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

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 either: Add ready label to the PR or enable auto-merge.

I wonder whether we can have simple tests that apply randomly initialized LoRA adapter just to check that the LoRA adapters can be loaded into the model? (Can do this in another PR)

We only need to set enable_lora when initializing the LLM to achieve this testing purpose, but considering the CI pressure, I'm not sure if it's necessary.

We can add a test similar to test_can_initialize and skip the test by default. The test can be enabled manually and run locally.

Sound good, I will try adding this in the following PR

I remember these names are used by InternLM2. Dose this work for InternVL models with other backbones besides InternLM2 (like Qwen2.5)?

It probably isn't supported
