Numpy, matplotlib crash Python 3.8.7 (tags/v3.8.7:6503f05, Dec 21 2020, 17:43:54) [MSC v.1928 32 bit (In tel)] on win32 (Windows 7)

This post was flagged by the community and is temporarily hidden.

You have shown a crash in NumPy, not Matplotlib. We cannot help with that.

you are not correct
in the listing above
I have run either

import numpy as np


  import matplotlib.pyplot as plt

to generate 2 crash reports as above ( a single report for Matplotlib follows below)

thank you for your reply


Matplotlib imports NumPy, so if NumPy is broken, then so will Matplotlib.

And this, from your second report, is still part of NumPy.

thank you my dear friend.

Could you explain me, so why should I import numpy
if already “to be imported” by Matplotlib

I am newbie with Python.
All I need is to run and test the code from

if Joseph runs the following code

Python program to read .csv file

import numpy as np
import matplotlib.pyplot as plt
import csv

– does it mean 2 instances of numpy get imported , one as numpy and the second as np ?

Should I test WinPython to avoid problems with numpy ?

thank you


I cannot help you learn Python. This Discourse is for Matplotlib-specific questions, not general Python help. There are many tutorials on the Internet teaching Python.
