Actually, because of the use of reshape(3,3,4), your second example does make a copy.
When does reshape return a view and when does it return a copy? Here's a simple example that returns a view:
x = np.array([1,2,3,4]) y = x.reshape(2,2) y[0,0] = 9 x array([9, 2, 3, 4])
What's a simple example that returns a copy?
