DeprecationWarning:np.int is a deprecated alias for the builtinint. To silence this warning, useint by itself. Doing this will not modify any behavior and is safe. When replacingnp.int, you may wish to use e.g.np.int64 ornp.int32 to specify the precision. If you wish to review your current use, check the release note link for additional information.

Changed the logic to check for an instance of both 32 & 64-bit ints.

Thenp.int is covered by the builtinint:

>>> isinstance(np.int(1), (int, np.int32, np.int64))True>>> isinstance(int(1), (int, np.int32, np.int64))True
