[Numpy-discussion] Funny business with 'is' operator?

[James Bergstra]

Hi, could someone help me understand why this assertion fails?

def test_is(self):
    a = np.empty(1)
    b = np.empty(1)
    if a.data is not b.data:
        assert id(a.data) != id(b.data) # <-- fail

I'm trying to write an alternate may_share_memory function.

Thanks,
 - James
