Similar ticket #212

Tried to solve it by using sudo pip3 install --upgrade matplotlib no luck. Not sure on the cause

commented

this looks like a matplotlib issue. you may upgrade your matplotlib installation.

Tried python3 -m pip install -r requirements.txt and I see that the latest version is v3.7.2 which matches what this website says https://pypi.org/project/matplotlib/ .

Still getting the same error. What version of mathplotlib you got?

commented

3.7.2 here

commented

after a quick code analysis this looks heavily related to your Gtk version used in python.
see https://github.com/matplotlib/matplotlib/blob/56732ffcf7a8eb2f4cdbe6835fdc985207c44e09/lib/matplotlib/backends/_backend_gtk.py#L146

or try

from gi.repository import Gtk
Gtk.get_major_version()

as long as you rely on Gtk 3 this warning will appear. with Gtk 4 this will be gone...

How do I switch to gtk4?

Python 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import Gtk
<stdin>:1: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
>>> Gtk.get_major_version()

Yup it's gtk v3. I attempted to install gtk v4

sudo apt install libgtk-4-1
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libgtk-4-1 is already the newest version (4.6.9+ds-0ubuntu0.22.04.1).
The following packages were automatically installed and are no longer required:
  linux-headers-5.15.0-78 linux-headers-5.15.0-78-generic linux-image-5.15.0-78-generic linux-modules-5.15.0-78-generic linux-modules-extra-5.15.0-78-generic
Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 8 not to upgrade.

I then ran the version check again and still got v3 for gtk, so not sure how to switch global python gtk version.

you don't need to take any action. This is a warning to the matplotlib maintainers and the distro maintainers.
With future distro upgrades the dependencies gtk version will be upgraded once gtk3 is fading out...

If you'd like to give it a try you can also dig further and upgrade manually... maybe your installation misses gir1.2-gtk-4.0
