Pycharm backend issue

Question

I see that this is a common issue but I have yet to see a fix for it. I am using the latest pycharm community, and i am running a script from the python console, but any time I try to load matplotlib or stellargraph in particular, I get the following:

Traceback (most recent call last):

AttributeError: 'InputHookManager' object has no attribute '_stdin_file'

Has anyone found a fix for this? Is it a setting in the interpreter or the console itself? I checked that i have ipython as well. Please help! Thanks in advance.

Answer 1

Found the solution:

GoTo: Run -> Edit Configurations

Under Environment, there is "Environment Variables", ensure DISPLAY=True is in the box, click enter.

Fixed it for me.
