Does anybody has a clue, why this command leads to this error? I am trying to install that on a Windows10 machine with a NVIDIA GPU and CUDA and Python 2.7.14 installed.

The DOS command:

python -m pip install pyopencl

The Output / Error:

I got it work with the Windows32-bit version of Python 2.7.13. - user3084928
I think I had some issues with the Python 2.7 version. I switched to Python 3 and it worked. - benshope

This answer in this post may help. Check out my answer there. Basically, the installation is done by installing the correct version of WHL file for your system.

This part of the log:

Cannot open include file: 'CL/cl.h': No such file or directory error

tells me the OpenCL headers are missing. You should install an appropriate SDK. Since you have an NVidia, I suggest you look in here.
