Description
Bug Report
Description
While working with conda-forge release, I found the datajoint-feedtest test would fail for me on python 3.13
python -c 'import datajoint as dj; assert dj.diagram.diagram_active'
# ModuleNotFoundError: No module named 'pkg_resources'
Reproducibility
Include:
- OS (Linux)
- Python Version 3.13
- DataJoint Version Unreleased 3e39771
- Minimum number of steps to reliably reproduce the issue
which conda
# /home/drewyang/miniconda3/condabin/conda
conda --version
# conda 25.1.1
conda create -n dj313 -c conda-forge python=3.13 # installed from conda-forge instead of the defaults channel 'conda-forge/linux-64::python-3.13.2-hf636f53_101_cp313'
conda activate dj313
# cd <datajoint-python repo>
git checkout 3e3977147aedcef735561427664a4c7a81d3862f # latest master as of 20250320
pip install -e .
python -c 'import datajoint as dj; assert dj.diagram.diagram_active'
- Complete error stack as a result of evaluating the above steps

Expected Behavior
which conda
# /home/drewyang/miniconda3/condabin/conda
conda --version
# conda 25.1.1
conda create -n dj312 -c conda-forge python=3.12 # installed from conda-forge instead of the defaults channel 'conda-forge/linux-64::python-3.13.2-hf636f53_101_cp313'

pip install -e .
python -c 'import datajoint as dj; assert dj.diagram.diagram_active'
# No output or error
Additional Research and Context
setuptools isn't a default dependency of Python 3.13 anymore, suggest to add to the pyproject.toml.
However, I also tried the same on Mac, which installed the conda default channel's python 3.13 for osx-64, it does include setuptools, which didn't cause the same issue.
I suggest we explicitly include setuptools in pyproject.yaml as a dependency(not a build dependency, but a package dependency)
Also setuptools.pkg_resources will be deprecated.
Use of pkg_resources is deprecated in favor of importlib.resources, importlib.metadata and their backports (importlib_resources, importlib_metadata). Some useful APIs are also provided by packaging (e.g. requirements and version parsing). Users should refrain from new usage of pkg_resources and should work to port to importlib-based solutions.
