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.

@wolph wolph changed the title ValueError: could not convert string to float: b'np.float32(0.0)' numpy 2.x breaks the tests: ValueError: could not convert string to float: b'np.float32(0.0)' Aug 17, 2024

The new release with the fix is out now!

With a bit of luck I've fixed the configuration of the stalebot too... hard to debug that thing ;)
