installed numpy but can't import

Question

I have already looked at other questions, but they either haven't been the same situation or haven't worked.

I am using windows 10. I had python 3.6, 3.7, and 3.7.2 (weren't on path) so I downloaded 3.8 and added to path during download.

on cmd did "pip install numpy"

C:\Users\Aidan>pip install numpy

C:\Users\Aidan>python.exe -m pip install numpy
Requirement already satisfied: numpy in c:\users\aidan\appdata\local\programs\python\python37\lib\site-packages (1.17.4)

When I go to python 3.8 this happens:

>>>import NumPy
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    import NumPy
ModuleNotFoundError: No module named 'NumPy'

and the same happens in 3.7 and 3.6.

I have tried pip uninstall and pip install again.

C:\Users\Aidan>pip uninstall numpy

From my research I know that having multiple pythons can be sometimes be a problem, but it never says why or which ones I need to get rid of to make it work. Below I will provide any extra info that may help.

This was the first time I've ever done anything with path or downloading modules so sorry for being a noob at this stuff.

I think there is a problem with the latest (1.19.4) NumPy version: try installing

pip install numpy==1.19.3
