The tutorial start.py cannot be executed properly

[MidnightBiscuit]

Describe the error

I am using the the code given as an example at https://3b1b.github.io/manim/getting_started/quickstart.html (SquareToCircle class). Those 9 lines of code are saved in G:\toto\start.py. I launch this in Anaconda prompt with python 3.12 activated. I installed ffmpeg and added to PATH, I then ran pip install manimgl.
Note that the install structure is different from the one shown at this page, after running pip install manimgl I have :

manimlib/
│ ├── animation/
│ ├── ...
│ ├── default_config.yml
│ └── window.py
├── custom_config.yml

Also, note that running manimgl alone, I have a grey window that is not responding, and typing anything in the console does nothing.

Code and Error

The command I execute is the following, with the command output and the error following

Code:

3.10 is working for now, I got the same issue. Major issue with numpy library, version conflict.

You need to downgrade the numpy version:

"numpy~=1.24",
