Description

When installing the latest version of development, POSYDON installs but cannot run when the active-learning is loaded. The following error is thrown:

  File "/srv/astro/projects/posydon/software/conda_envs/posydon_240913/lib/python3.11/site-packages/sklearn/base.py", line 17, in <module>
    from .utils import _IS_32BIT
  File "/srv/astro/projects/posydon/software/conda_envs/posydon_240913/lib/python3.11/site-packages/sklearn/utils/__init__.py", line 19, in <module>
    from .murmurhash import murmurhash3_32
  File "sklearn/utils/murmurhash.pyx", line 1, in init sklearn.utils.murmurhash
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

A search indicates that this is an issue with scikit-learn and numpy. It looks like a too new version of numpy is installed (>=2.x.x) for the scikit-learn version (1.2.2).

A limit should be set on which numpy version is installed or scikit-learn should be updated.

Contributor guide

Research direction
Investigate the current versions of scikit learn and numpy in the project's dependencies, check their compatibility, and update the version constraints in setup.py or requirements files to resolve the binary incompatibility error.
