👋 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.

🚀

Thanks for the patch, makes sense

Does cython not allow subscripting type? We are using Python 3.9 already so it should be supported in pure Python.

Lowercase type is not a type hint, but rather a keyword and a function, for the type hint there is Type from typing.
While pure python ignores type hints in runtime, cython builds the compilable C code based on them, with strong runtime checks, and so it fails in runtime due to
TypeError: 'type' object is not subscriptable

I'm aware that this is not a type hint. The ability to subscript type directly was added in Python 3.9 (PEP 585), which deprecates the use of typing.Type. Is that not the case for Cython?

Apparently not for type. According to the issue tracker it is supposed to be working for collections.
