Any guideline to avoid this error ?

Yeah, it's strange it's trying to build the wheel for h5py (I think).

It seems to be stopping when installing h5py. Are you able to pip install that? It seems to be working ok for me:

Are you sure you are working with a clean local environment?

[mkundu1]

The issue is for Python 3.11 (duplicate of #1147). Our supported versions are Python 3.7 - 3.10 as per README.

[dnwillia-work]

Yeah, well spotted. You can see it here lib.win-amd64-cpython-311 <<<

[amscosta]

Thanks a lot.
