Unable to load kivy examples

[test]

Hello. I've been trying to use the kivycatalog example to practice writing .kv files. However, running the main.py file is returning the following:

I tried installing gstreamer, etc as was suggested in some discussions, but it did not resolve the problem.

using apt, on trying to get the examples, i was not able to locate the directory, so i downloaded the examples from git-hub manually and placed the folder in /usr/lib/python3/dist-packages/kivy. That is probably why it is not working.
How can i get it to run?

Is there some other way i can reder files like that example does, in order to practice?
Thank you.
