I think you need to specify NPY_LONG instead of NPY_INT -- the NPY_INT is IIRC sort of a "virtual type" that you can use when creating arrays, but no array is ever of type NPY_INT, since it maps to either NPY_LONG or whatever the C "int" type happens to be. Maybe someone can correct me here, but AFAIK it goes like so. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
