  <p>I installed manim by copying the repo with git. Then I made another file with code copied from this tutorial <a href="https://talkingphysics.wordpress.com/2019/01/08/getting-started-animating-with-manim-and-python-3-7/" rel="nofollow noreferrer">https://talkingphysics.wordpress.com/2019/01/08/getting-started-animating-with-manim-and-python-3-7/</a> to see if the problem was on the example_scenes.py file, but i got the same result with an example from that page. I'm running Debian 10.</p>
