Description Sandro 2024-12-23 20:40:53 UTC
Currently, importing fast_simplification results in:

>>> import fast_simplification

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.1 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use '<void>numpy._import_array' to disable if you are certain you don't need it).

A simple bump and rebuild should fix that.

Reproducible: Always

Thanks for the heads-up! I’ll take care of the rebuild, dropping the patch that allowed building with numpy 1 while I’m at it.
