Cannot mix incompatible Qt library (version 0x50b01) with this library (version 0x50b02) Aborted (core dumped)

My code was running correctly, but now with the following ERROR message:

*Cannot mix incompatible Qt library (version 0x50b01) with this library
(version 0x50b02)*
*Aborted (core dumped)*

I actually just want to use *matplotlib* as:

import matplotlib.pyplot as plt
import matplotlib.dates as md

Now, whenever I want to use matplotlib, I got the above error...

Can anybody help?

Cheers

Did you just recently upgraded to matplotlib v3.0? I am guessing somehow
that upgrade also did some things to your QT libraries as well. You can try
changing your default backend to something like TkAgg so that it doesn't
try the QT based backends.

Can you do

import PyQt

without error? I suspect this is due to installation issues between Qt and
PyQt versions.
