New Manim version that supports GPU

I get an error in Colab trying to run Manim from “shaders” branch. I see tqdm for each animation, that means they are successful. But then it gets into a loop and I have to stop it with the error:

Traceback (most recent call last):

UPDATE: If you want to try it in Colab, the code is here.

[pythonian1027]

I tried running the project for SIR simulation (https://www.youtube.com/watch?v=gxAaO2rsdIs) and got this error: “~\Anaconda3\envs\manim\lib\site-packages\pyglet\canvas\base.py”, line 194, in get_best_config raise window.NoSuchConfigException() pyglet.window.NoSuchConfigException "

I was able to run the Test case but basically everything else crashed

I released a new version of moderngl-window what should at least solve the NoSuchConfig for a lot of people. You maye also have to go into the window.py module and set samples = 0.

@t-wolfeadam The shader error you are getting is an error in the glsl code here : https://github.com/3b1b/manim/blob/2ce0b72c440fadbfba990bdac8bc9c2ea8bff4e7/manimlib/shaders/quadratic_bezier_fill_frag.glsl#L41

It should return a float, not an int. Not all GLSL compilers are nice and convert constants for you automatically. I would fix that line and test it again. Make a PR as well while you are at it (if it works) 😄

You may see more of those, but they are quick and easy to fix if you search for the variable or function names reported by the GLSL compiler.
