Hi I am using Ubuntu: and Pycharm latest version(2019.2): if i import only matplotlib it does not show any error, however if i try to execute matplotlib.pyplot as plt it shows me below error: Please refer the note section below

import matplotlib.pyplot as plt
Backend GTK3Agg is interactive backend. Turning interactive mode 
on.

NOTE: I tried uninstalling matplotlib and pip3 and reinstalled it, I also installed the Six : pip3 install Six, however, the issue remains the same

This is an internal pycharm error. You can contact pycharm support about it. — ImportanceOfBeingErnest

Here's a workaround: Use a different backend (from gtk/gtk3)

import matplotlib                #only import mpl first
matplotlib.use("agg")            #then set backend
import matplotlib.pyplot as plt 

plt.figure()
plt.plot([1,1])
plt.savefig("name.jpg")

I haven't tested other backends yet, but this works. Of course this is no permanent solution but just a quick emergency fix if you need the figures.

The problem is with gtk/gtk3 (I think). Also shown in PY-16043 Failed to enable GUI event loop integration for 'gtk' (see https://youtrack.jetbrains.com/issue/PY-16043 , which is the link BugsBunny already put).

The Error occurs when the enable_gtk/enable_gtk3 method is defined. So if you don't use this backend, you avoid the error.

Use:

import matplotlib
matplotlib.use("TkAgg")
import matplotlib.pyplot as plt

And it does the trick
