ModuleNotFoundError: No module named 'peachpy.x86_64.avx' about nnpack HOT 7 OPEN

This error occurs for me on both Ubuntu 18.04 with GCC 7.5.0 and on macOS 10.15.7 with Apple Clang 12.0.0.

It looks like peachpy/x86_64/avx.py is supposed to be generated by opcodes. If I build peachpy on its own it works fine. I'm guessing there's something wrong in the CMake configuration and opcodes isn't being used.

Workaround: if I set -DNNPACK_BACKEND=psimd I can skip the peachpy dependency altogether and get NNPACK to build. I have no idea what the performance consequences of this are.

I think when PYTHON_PEACHPY_SOURCE_DIR is set, we don't run python setup.py generate. Also, I noticed that the PYTHONPATH gets overridden, so Python can't find my setuptools which is set in a different directory.

Hi I've been stacked by the same problem when building pytorch, which uses NNpack and peachpy as submodules. Do you have any idea to fix this? Thanks!

Probably it could be related #202

Hello,I also encountered this issue while installing Pytorch and it has now been solved.You need to execute python setup.py generate under /pytorch/third_party/python-peachpy/ path
