numpy<=1.24

[bagang52]

I had a same error...
OS System: Ubuntu 23.04 Codename: lunar
manim version: ManimGL v1.6.1
python version: Python 3.11.
numpy version: 1.24.2

apt-cache madison python3-numpy
python3-numpy | 1:1.24.2-1 | http://cn.archive.ubuntu.com/ubuntu lunar/main amd64 Packages

How can Numpy be downgraded to versions below 1.24?

pip install numpy==1.24 worked for me

[shallow-beach]

after following all steps on the MacOS guide, i needed to use pyenv with pipenv to get a version of pip that would play nice with pip install numpy==1.24. my python distribution was acquired using pyenv install 3.8 which defaults to 3.8.18, and for some reason i needed to manually edit Pipfile and Pipfile.lock to use 3.8, as pipenv install wouldn't use the correct (local) python distribution.

some examples within example_scenes.py do not run, but some do. regardless all show:
WARNING Unsupported element type: <class 'svgelements.svgelements.Use'>
at runtime, typically along with a few other errors.

Here are the calls that fail before displaying anything:
TexTransformExample
TexIndexing

pip install numpy==1.24 worked for me

I can confirm on WSL2 that installing numpy==1.24.0 fixed the shape operand issues with manimgl for me.

Thanks for figuring this one out.
