To create a minimal reproducer (I used Python 3.11.9):
python -m venv test_nc4 source test_nc4/bin/activate pip install netcdf4 python -c "import numpy;import warnings;warnings.filterwarnings('error');import netCDF4"
This will raise an error with: numpy.ndarray size changed, may indicate binary incompatibility. Expected 16 from C header, got 96 from PyObject
numpy.ndarray size changed, may indicate binary incompatibility. Expected 16 from C header, got 96 from PyObject
This isn't numpy 2.0 specific, pip install netcdf4 "numpy<2.0" will raise the same warning.
pip install netcdf4 "numpy<2.0"
To the best of my understanding this means that the numpy that was used during the netcdf4 build is incompatible with the numpy version I'm using.
netcdf4
I know that this is usually just a warning, but this means I've got to manually ignore these in my pytest suite.
It's also hard to gauge for a user whether this warning is problematic. Thus I'm wondering if this can be fixed on the netcdf4 side?
