Post your code, so that we can see what you actually did. If I had to guess, I'd say you forgot to define your 'Mrc' attribute in your ndarray_meta.__array_finalize__. But once again, without some code, it's only a guess. _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
