The control package is intended to support NumPy 2 (python-control/python-control#1013 and python-control/python-control#994), and control uses Slycot, so the key question is: can Slycot be made compatible with both NumPy 1 and 2?

If not, or if it requires a lot of work, then your proposed change is a good temporary solution.

I think building the wheels with NumPy 2 makes them compatible with NumPy 1 and 2

EDIT: https://numpy.org/doc/stable/dev/depending_on_numpy.html#numpy-2-0-specific-advice

There are no Slycot wheels on PyPI. We only publish the source distribution and it is compatible with NumPy 2.

My bad, there must be something else wrong on my end.

No worries, feel free to ask if you need more help. You probably just have to recompile/reinstall Slycot with numpy 2. Make sure to not use a previously compiled wheel from your local cache.

Thanks, the problem was actually a previously compiled wheel in my cache.

EDIT: To be more specific, the --no-cache-dir option in pip solved it for me.
