Looks like numpy 2.0 is just around the corner: numpy/numpy#24300. But in the meantime we should still update the numpy version currently used, since we are still using 1.7 deprecated api:

• Remove the #define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION and fix the api
• Numpy has minimum version of 3.9, maybe we should bump it as well, although pip install should pick up the appropriate version automatically
