numpy dtype problem

[liuzh1206]

The new version of numpy no longer supports the float and complex data types. When I use it, I get an error message and the following prompt: The program can run normally after changing np.float and np.complex to np.float64 and np.complex128 in the code.

`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:

Thanks for noticing this. It should be fixed now. I will push a new version soon.
