incompatible with numpy 1.24 and later

Using dtype=np.complex has been deprecated since numpy version 1.20. With numpy versions up to 1.23 using np.complex would cause a numpy warning to be issued, but since 1.24 the warning is now an error.

AttributeError: module 'numpy' has no attribute 'complex'.
`np.complex` was a deprecated alias for the builtin `complex`. To avoid this error in existing code, use `complex` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.complex128` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
