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.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
NumPy 1.20.0 Release Notes — NumPy v2.0.dev0 Manual

Hi,

Could you try to install numpy v1.23 and try it again?

$ pip3 install numpy==1.23.1

Thanks.

Thanks for the response. i went to the source code and changed np.bool to bool and it worked
