Failed to load module "appmenu-gtk-module"

Hello

I am running Arch Linux and I am running into this error

The support for Qt4  was deprecated in Matplotlib 3.3 and will be removed two minor releases later.
  from matplotlib.backends.qt_compat import QtGui
[win_size] = 512
[image_file] = test_imgs/mortar_pestle.jpg

I have installed all of the listed dependencies. I am using pytorch because I could not get Caffe installed on my system (pytorch was easier). I assume the error is handling with the UI but I am not sure what it is caused by.
