python - 如何在 Colab 中设置 Pyglet 以与 Manim 一起使用？

问题描述

我正在尝试在 Colab中运行Manim 的着色器版本。此版本必须在实时交互窗口中显示渲染视频，而不是仅仅编写 mp4。我安装并导入了所有内容，没有错误：

from manimlib.imports import *

但运行时出现异常：

!python3 -m manim example_scenes.py OpeningManimExample

Media will be written to ./media/. You can change this behavior with the --media_dir flag.

解决方案

Colab 在云端运行。

它不能使用 pyglet 在您的计算机上打开一个新窗口以进行实时显示。

所以，着色器版本是不可能的。你能成功运行mp4版本吗？
