FXPy Is referenced in the docs, but is not usable in any recent python, even by centos standards. FXPy is only, as far as I can get it working, for 1.5.2 through 2.2. There is no python 3 port, so it shouldn't be in the 3.x docs at all. Should... probably... remove that from the docs. https://docs.python.org/3/faq/gui.html#fox
