WebYou can add that extra dimension as follows: a = np.array (a) a = np.expand_dims (a, axis=-1) # Add an extra dimension in the last axis. A = np.array (A) G = a + A Upon doing this and broadcasting, a will practically become [ [0 0 0 0 0 0] [1 1 1 1 1 1] [2 2 2 2 2 2] [3 3 3 3 3 3]] WebJun 6, 2015 · NumPy isn't able to broadcast arrays with these shapes together because the lengths of the first axes are not compatible (they need to be the same length, or one of them needs to be 1 ). Inserting the extra dimension, data [:, None] has shape (3, 1, 2) and then the lengths of the axes align correctly: (3, 1, 2) (2, 2) # # # # lengths are equal ...
