problem with Matplotlib
#1
When I try to generate a plot (via Matplotlib), the output is as follows:

import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib'

I checked via my terminal whether or not I have pip. I do:

pip 20.1 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)

Does anyone have any suggestions?

First type this in a terminal

Output:
pip install -U matplotlib
Wait until the install is completed.

Hi Gribouillis,

All in all, the download is complete. I received a warning output message, however, in reference to the pip version I currently have (i.e. 20.1). Should I be concerned about this? Is it necessary to download the most recent version (i.e. 20.1.1)? Below is what appeared in my terminal. Thank you!

No, upgrading pip from version 20.1 to 20.1.1 may not be the most urgent thing to do.

OK. I did research into BBcode and will do my best to use tags correctly in my future posts. Thank you.
