Hi,
Windows 10, Openvino 2020.2. I use open_model_zoo\demos\python_demos\human_pose_estimation_3d_demo, refer to https://github.com/opencv/open_model_zoo/blob/master/demos/README.md#build-the-demo-applications, my command as following:

cd C:\Program Files (x86)\IntelSWTools\openvino\bin\
setupvars.bat
cd C:\Program Files (x86)\IntelSWTools\openvino_2020.2.177\deployment_tools\open_model_zoo\demos\python_demos\human_pose_estimation_3d_demo\pose_extractor
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_PYTHON=ON "C:\Program Files (x86)\IntelSWTools\openvino_2020.2.117\deployment_tools\open_model_zoo\demos\python_demos\human_pose_estimation_3d_demo\pose_extractor"

and get error:

-- Detecting CXX compile features - done

Try python -m pip install numpy and recompiling after.

BTW you are not supposed to run pose_extractor's cmake directly. This approach is not going to work with later releases. It is safer to run demos root cmake.
