It appears that pyarrow requires a CPU with SSE 4.1 due to the [PINSRQ](https://www.felixcloutier.com/x86/pinsrb:pinsrd:pinsrq) instruction: ``` $ python -m venv .venv $ source .venv/bin/activate $ pip install pyarrow Collecting pyarrow Using cached pyarrow-16.0.0-cp312-cp312-manylinux_2_28_x86_64.whl.metadata (3.0 kB) Collecting numpy>=1.16.6 (from pyarrow) Using cached numpy-1.26.4-cp312-cp312-manylinux_2_17_x86_64.manylinux2014_x86_64.whl.metadata (61 kB) Using cached pyarrow-16.0.0-cp312-cp312-manylinux_2_28_x86_64.whl (40.8 MB) Using cached numpy-1.26.4-cp312-cp312-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (18.0 MB) Installing collected packages: numpy, pyarrow Successfully installed numpy-1.26.4 pyarrow-16.0.0 $ objdump -S .venv/lib/python3.12/site-packages/pyarrow/lib.cpython-312-x86_64-linux-gnu.so | grep pinsrq 6e8b2: 66 48 0f 3a 22 c2 01 pinsrq $0x1,%rdx,%xmm0 6e8cd: 66 48 0f 3a 22 c2 01 pinsrq $0x1,%rdx,%xmm0 6e8eb: 66 48 0f 3a 22 c2 01 pinsrq $0x1,%rdx,%xmm0 6e90d: 66 48 0f 3a 22 c0 01 pinsrq $0x1,%rax,%xmm0 6e93a: 66 48 0f 3a 22 c0 01 pinsrq $0x1,%rax,%xmm0 6e9df: 66 48 0f 3a 22 c0 01 pinsrq $0x1,%rax,%xmm0 6e9fd: 66 48 0f 3a 22 c0 01 pinsrq $0x1,%rax,%xmm0 6ea1b: 66 48 0f 3a 22 c0 01 pinsrq $0x1,%rax,%xmm0 ... ``` The first PINSRQ instruction gets called right at the module import. -- This is an automated message from the Apache Git Service.
