Reproduction Steps

Installing the latest version of VLLM will install mistral-common==1.4.1; which leads to crash (see above).

Expected Behavior

VLLM should work with latest mistral-common :-)

Additional Context

No response

Suggested Solutions

As a workaround, I'm installing mistral-common==1.4.0, which works fine.

Probably the latest introduction of cv2 has caused this error. Maybe use just open-cv and not the headless package version?

For me installing mistral-common==1.4.0 also doesnt work. It also does crash vLLM. I have python 3.8.8

pip install mistral-common==1.4.0
