Matplotlib raised QT-Wayland warning

Hi!

Whenever I try to use matplotlib (Python 3.7.x) I get the following warning:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

I tried, as suggested, setting QT_QPA_PLATFORM to wayland myself but it didn't work. I have checked and apparently, everything I need is installed and updated. (pyqt, qt5-wayland and matplotlib).

Re: Matplotlib raised QT-Wayland warning

https://wiki.archlinux.org/index.php/Wayland#Qt_5 lists several options to run qt5 stuff on wayland, please try them.
