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

As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:

./my_script.py

I got the ImportError: No module named numpy because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct. All I needed was to run the script like this:

py my_script.py

And this way the problem was solved.
