[github-actions]

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀

@maxdebayser do we need to include that in tests/utils/test_upstream_compatibility.py? We already have test_pooler_from_config(), so anyone replacing that will see that there is another if branch there...

[maxdebayser]

Yeah, I think it's better to add a test specifically for this, since the default_normalize refactoring is a discrete change in vllm.

[yannicks1]

@maxdebayser, I added the test in tests/utils/test_upstream_compatibility.py. If you could have a quick look and approve that would be great.
