`np.bool` was a deprecated alias for the builtin `bool`.

[Uzukidd]

Exception has occurred: AttributeError module 'numpy' has no attribute 'bool'. np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here.

np.bool has been deprecated ifrom NumPy 1.20.
Replace everynp.bool to bool to make it works.
