Not really, numpy depends too much on cpython internals. There is an interest in rewriting numpy for pypy, but I am not sure whether this is the best way of doing it. From what I understand, the choice is between better pypy's compatibility with C extensions (easier, but slower because of cpython emulation in pypy) vs rewriting it for pypy (harder, but would benefit more from pypy).
