Hi I made a NumPy-like library for tensor math that can be used from GDScript and C#. It's called NumDot, and you can find it here: https://numdot.readthedocs.io/
Currently, after a few weeks of hard work, I'm starting to involve more testers, to get it out of beta. If you're interested in fast, easy to write vector math for Godot, I'd be grateful for any kind of involvement!
You can find the repository here.
You can also join the project's community on Discord here.
