Hi Nathan, That is a good point: Yes, one can leave __array_prepare__ and __array_wrap__ in place: only for ufuncs will they be ignored if __array_ufunc__ is present; __array_wrap__ in particular will still be used by quite a lot of other numpy functions (other use of __array_prepare__ is usually a mistake, but sadly does happen...).
Anyway, with older versions of numpy, code should continue to work as it did. All the best, Marten p.s. It is also important to leave __array_prepare__ and __array_wrap__ in place for possible other classes that assume your class is wrapped that way... p.s.2 The same holds for __array_priority__ _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discussion
