ModuleNotFoundError with numpy 2.0

[felixchenier]

ezc3d doesn't import when NumPy 2 is installed.

NumPy 1

conda create -n test1 python=3.12 numpy=1 ezc3d

In this case, this is the version of ezc3d that gets installed:

ezc3d-1.5.10 |py312_python3_h265b4a9_2

>>> import ezc3d

works

NumPy 2

conda create -n test1 python=3.12 numpy=2 ezc3d

In this case, this is the version of ezc3d that gets installed:

ezc3d-1.5.10 |py312_octave_hcae72de_2

(Note "octave" instead of "python")

>>> import ezc3d

ModuleNotFoundError: No module named 'ezc3d'

Hi @felixchenier

Trying to force the installation of python based ezc3d when forcing numpy=2 returns an error reporting fatal incompatibility (conda install ezc3d=*=*python* numpy=2 -cconda-forge)

Looking at the corresponding file in anaconda (https://anaconda.org/conda-forge/ezc3d/files) we can see that ezc3d is properly installed. That basically means that conda is not ready yet to install all dependencies of ezc3d if numpy 2 is required. This is not on my side I think, but only on conda-forge side which has not yet ported all their libraries to numpy 2
