If you want the behaviour of the first, use train_set_x_orig.reshape (train_set_x_orig.shape [0],-1).T. The difference I was talking about is this, for instance: X.reshape (X.shape [0],-1).T versus X.reshape (-1,X.shape [0]): both give you an array of shape (N,X.shape [0]), but the elements will be mangled in the latter ...
