raceback (most recent call last): File "extract_scene.py", line 168, in <module> main() TypeError: main() missing 1 required positional argument: 'config'

[DarkRinzler]

Hi guys, I am new to manim and I have tried to solve this problem on my own but can't figure how to do it. When I try to run the command "python3 extract_scene.py example_scenes.py SquareToCircle -pl" the following error line pops out on the terminal "raceback (most recent call last): File "extract_scene.py", line 168, in main() TypeError: main() missing 1 required positional argument: 'config' ". However if I run the command "python -m manim example_scenes.py SquareToCircle -pl " the video file is created and everything works fine. Any suggestions on how to correct this issues?

No such execution

you can use the param video_output_dir specify output path ; default path is ./media

$ python manim.py --save_as_gif old_projects/cba.py DifferenceOfSquares -pl --video_output_dir=output
Media will be written to .\media\. You can change this behavior with the --media_dir flag.

File ready at E:\workspace\dev\manim\output\DifferenceOfSquares.mp4

Played 4 animations

Ok thanks very much. Another issue comes at end. I get error for undefined colors and warning because of wildcard import. Is there a way to correct this issues? I know that in order to get rid of the warning I should not use "from manimlib.imports import *" but rather import the libraries needed each time. Where can I see such a list?

it's this?

"""
I won't pretend like this is best practice, by in creating animations for a video,
it can be very nice to simply have all of the Mobjects, Animations, Scenes, etc.
of manim available without having to worry about what namespace they come from.

Rather than having a large pile of "from <module> import *" at the top of every such
script, the intent of this file is to make it so that one can just include
"from manimlib.imports import *".  The effects of adding more modules
or refactoring the library on current or older scene scripts should be entirely
addressible by changing this file.

Note: One should NOT import from this file for main library code, it is meant only
as a convenience for scripts creating scenes for videos.

yes. But the option * is selecting all the possible libraries right?
