It seems that numpy 2.x has made some changes that cause many of the tests to fail. If you go back to numpy 1.x the tests will work again, but it will take some time to update all of the tests to work with numpy 2.

I have the same problem, I tried to do a PR here: https://github.com/wolph/numpy-stl/pull/224
