Unable to run Python program in PyCharm

I have created a Python program that runs in Atom (and Terminal) on my Mac, but I'm unable to run the program in PyCharm Edu. I haven't had any problems running other programs in PyCharm.

It seems to be a problem with my installation of matplotlib and/or NumPy. I have installed matplotlib (which included NumPy) using pip3. After the installation the import commands worked successfully (in Terminal).

The code is very short :-

import matplotlib.pyplot as plt

squares = [1, 4, 9, 16, 25]
plt.plot(squares)
plt.show()

While the error message is quite long: -

1
2
3
4
[1, 2, 3, 4, 5]
[2, 4, 6, 8, 10]
Traceback (most recent call last):

  Although I have managed to execute the code successfully in Atom, I would prefer to use PyCharm for my Python work. As you can tell I'm a newbie to Python, but would really appreciate some assistance with this issue. If further information is required, please ask.

TIA.
