Some (most?) scipy modules cannot be used with NumPy 2: python3-scipy-1.14.1-1.fc42.x86_64 python3-numpy-2.2.0-1.fc42.x86_64 Reproducible: Always Steps to Reproduce: >>> import scipy.ndimage as ndimage Actual Results: A module that was compiled using NumPy 1.x cannot be run in NumPy 2.2.0 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.

koschei shows a test failure with numpy 2.0: https://koschei.fedoraproject.org/package/scipy I've filed https://src.fedoraproject.org/rpms/scipy/pull-request/50 which hopefully fixes that. If that build I'll merge and build unless someone else gets to it first.
