TL;DR Summary
Installed successfully but won't import
I'm running Python 3.8.3 on Windows 10 and was have installed matplotlib, but I can't get it to work. If I try import matplotlib then first it seems to spit out some output (always the same) from a couple of basic test programs I wrote (which is really weird), then just gets a bunch of errors:

c=300000000
Favorite number is 1729
Traceback (most recent call last):

numbers.Integral.register(integer)
AttributeError: module 'numbers' has no attribute 'Integral'

I've been down a rabbit hole with this most of the day. I've tried what I found here, messing about with different WHL files:

Any ideas?

Thanks

Are you using pip or anaconda?

It looks like you have a numbers.py file somewhere in your python search path aka PYTHONPATH that is being processed over the correct one needed by numerictypes.py

Look through your code to see if you have a file you named numbers.py
and change its name.

Aha, that was the test program that was printing the speed of light and the number 1729.

It's gone and that seems to have fixed it. Thanks a million!

Great, I’m glad that was easy to find. We don’t use pip for our projects instead we use anaconda which comes loaded with a lot of modules all in one tar because works better in an airgapped environment with no internet access.
