When I follow your tutorial, the class MovingCharges(Scene) doesn't work. Maybe something has been changed in manim project. So the following three lines need to be changed

1. manim_tutorial/manim_tutorial_P37.py

   Line 493 in 37efeb9

   self.always_continually_update = True

2. manim_tutorial/manim_tutorial_P37.py

   Line 503 in 37efeb9

   def continual_update(self, *args, **kwargs):

3. manim_tutorial/manim_tutorial_P37.py

   Line 505 in 37efeb9

   dt = self.frame_duration

as

self.always_update_mobjects = True

def update_mobjects(self, *args, **kwargs):

dt = 1 / self.camera.frame_rate

When I try to render the scene ExampleApproximation of manim_tutorial_1.py, I obtain in Terminal this error:

NameError: global name 'math' is not defined

for line 234.
Actually, big_ol_pile_of_manim_imports.py has not an import math line in the May 9, 2018 commit of manim, the manim version you suggest to use in your talkingphysics.wordpress.com tutorials.
(recent versions of manim have the line import math in big_ol_pile_of_manim_imports.py)

I keep getting "No module named 'manimlib.main'" when i try run manim or manimgl. i try to update pip and miktex but its also keep getting the same error. Some says you need to get newer version of python, but Im with python 3.9. Can anyone help me?

I'm using Manim Community Edition v0.8.0. I'm having problems running scenes ExampleApproximation and PlotFunctions. I'm experiencing problems in reading the values inside the dictionaries named "CONFIG". Do you have any idea how to solve it ?

This looks super cool.
