Numpy version must be 1.22 or less

Hey

@Yuliang

you seem to have pushed a different requirement for `numpy>=1.22` which installs version `1.23.1` not supported by Numba and apparently neither by scipy
`
UserWarning: A NumPy version >=1.16.5 and <1.23.0 is required for this version of SciPy (detected version 1.23.1)
`
`
ImportError: Numba needs NumPy 1.22 or less
`
