🚀 The feature, motivation and pitch

The vllm 0.19.0 wheel (at least on window) still needs a transformers 4.X version. Would be good of a newer vllm release would support transformers 5.X.

TL;DR

Update the vllm wheel to a version that supports transformers 5.X to resolve compatibility issues.

Guidance

  • Check the vllm documentation for any upcoming releases that support transformers 5.X.
  • Verify the current version of transformers installed in the project to confirm the version mismatch.
  • Consider reaching out to the vllm community or maintainers to request an update or provide feedback on the desired version support.
  • Review the project's dependencies to ensure no other packages are dependent on transformers 4.X, which could be affected by the update.

Notes

The solution relies on the assumption that a newer version of vllm will be released with support for transformers 5.X. If no such version is planned, alternative solutions may need to be explored.

Recommendation

Apply workaround: Wait for a newer vllm release that supports transformers 5.X, as updating to an incompatible version may introduce other issues.
