@pluflou I think I'm going to need your help here when you're available again 🙏

@pluflou tests now pass 🎉 can you provide your review for the PR?

this was the root cause of the numpy failures in the tests: https://numpy.org/doc/stable/reference/generated/numpy.linalg.solve.html

Changed in version 2.0: The b array is only treated as a shape (M,) column vector if it is exactly 1-dimensional. In all other instances it is treated as a stack of (M, K) matrices. Previously b would be treated as a stack of (M,) vectors if b.ndim was equal to a.ndim - 1.

Updates to the workflows (deleting the conda stuff) looks good to me!
