From @ralfgommers on the #NumPy issue tracker regarding #NumPy2:

Public service announcement: if your package uses pybind11 to interact with NumPy, you have to upgrade to the just-released pybind11 2.12.0: https://pypi.org/project/pybind11/2.12.0/.

The numpy 2.0.0rc1 is imminent, and it will not work with older pybind11 versions.

We recently prepared #scikitimage for #numpy2, which introduces a few significant changes to the promotion rules for scalars and arrays #nep50. So I thought to write up a few takeaways that hopefully make life a bit easier for you and your #numpy code:
