Warning on import cpmpy: exact.py:52: UserWarning: pkg_resources is deprecated as an API. #709
Description
When cpmpy 0.9.25 is imported, I get the following warning:
> python -c "import cpmpy"
/home/hbierlee/Projects/cpmpy/venv/lib/python3.12/site-packages/cpmpy/solvers/exact.py:52: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources p
ackage is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
import pkg_resources
Even though Exact is not installed. On the master (#14e9a064) branch, I get the same warning for gurobi (also not installed):
> python -c "import cpmpy"
/home/hbierlee/Projects/cpmpy/cpmpy/solvers/gurobi.py:46: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as e
arly as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
import pkg_resources
It's probably good to see if we can avoid these distracting warnings.
