It seems that B2's ref of A2 is stolen by this assignment out = B2. And In A3 , B3 case, we deleteout first and it seems that the ref in out is returned back to B3. I'm not sure if this is the intended behavior and I cannot find any material or documentation about this. Any thoughts or suggestions would be helpful! Teng Liu The statement `B2 = A2.reshape((10, 10))` increments the refcount of A2 in an indirect way: it is B2.base that holds the reference to A2. In fact, `B2.base is A2` is True. Therefore, incrementing the refcount of B2 (with `out2 = B2`) will not increment also the refcount of A2. Hope this helps, Stefano
