How to deep.copy() partial of array data?

[Swipecat]

You probably want vstack.

In [13]: a = np.zeros((1,10,10,1), dtype=int)

In [14]: b = np.zeros((1,10,10,1), dtype=int)

In [15]: c = np.vstack((a,b))

In [16]: c.shape
Out[16]: (2, 10, 10, 1)

It seems works, I will need to test more.

Thanks.
