This question already has answers here: Concatenate two NumPy arrays vertically (4 answers) Closed 3 years ago. I have two arrays X and Y, X has size (5000,2351) and Y has (2351,). I used reshape function for Y to get size (1,2351). Then I used append function to X and instead size (5001,2351) I get (117552351,). Y = Y.reshape(1,-1) X = np.append(X,Y) Where is a problem?

You can use np.concatenate: X = np.arange(0,15).reshape(5,3) Y = np.arange(0,3) Y = Y.reshape(1,-1) np.concatenate([X,Y]) yields: array([[ 0, 1, 2], [ 3, 4, 5], [ 6, 7, 8], [ 9, 10, 11], [12, 13, 14], [ 0, 1, 2]])
