NumPy 2.x requires X86_V2 instruction set (SSE4.2/AVX) which older server CPUs don't support. When building Docker images locally on newer hardware then deploying to older servers, pin numpy<2 in requirements.txt to use numpy 1.26.x which doesn't have this requirement. Error message: RuntimeError: NumPy was built with baseline optimizations: (X86_V2) but your machine doesn't support: (X86_V2).
