IIRC, it avoids one copy: ndarray.__reduce__ pickles the raw data as a string, and so ndarray.__setstate__ receives a Python string back. I don't remember if it's in the end possible to emit raw byte stream to a pickle somehow, not going through strings. If not, then a copy can't be avoided. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
