Python Problem importing matplotlib in Python

[PeroK]

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

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

pip

 

[jedishrfu]

It may be your PYTHONPATH has more than one numbers.py file. I think that file may generated by Numpy.

Here’s another report on it on github

https://github.com/numpy/numpy/issues/9872

and this one too

How do I fix that?

 

[jedishrfu]

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.
