Setup issue / NumPy headers not found

When I run python setup.py build_ext, I got this issue.

My environment: WSL2: Ubuntu18.04 OpenCV: Install according to this cmake version 3.10.2

Thank you very much! I delete .pyenv directory and create environment using virtualenv as you mentioned above. I could successfully build.

I believe you are still having issues with different Python versions. On Ubuntu libpose_extractor.so is linked against shared python library (/usr/lib/x86_64-linux-gnu/libpython3.6m.so in my case). I also see, that you probably have python3.6 as a system one. So python3-dev package was installed also for 3.6 version. And error log shows, that your environment is using 3.8.8 version. So try to make the proper environment (virtualenv -p /usr/bin/python3.6 venv_pose3d) and use it with this repository.
