Some updates may needed for numpy version >=1.24.0

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.

np.float may need to be updated to np.float64 if the recent version numpy is imported, as numpy 1.24.0 removed these aliases (e.g. numpy.float) completely.
