Import Error: No module named numpy

Question

I have a very similar question to this question, but still one step behind. I have only one version of Python 3 installed on my Windows 7 (sorry) 64-bit system.

Answer 1

I had numpy installed on the same environment both by pip and by conda, and simply removing and reinstalling either was not enough.

I had to reinstall both.

I don't know why it suddenly happened, but the solution was

pip uninstall numpy

conda uninstall numpy

uninstalling from conda also removed torch and torchvision.

then

conda install pytorch-cpu torchvision-cpu -c pytorch

and

pip install numpy

this resolved the issue for me.
