Hi everyone, As title, I can't figure out the output of the following mean value of the array_a: array_a = np.array([[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]) np.mean(array_a, axis = 0) np.mean(array_a, axis = 1) the output would be array([[4., 5., 6.], [7., 8., 9.]]) and array([[ 2.5, 3.5, 4.5], [ 8.5, 9.5, 10.5]]) accordingly. I may need someone's help of the explaination in this self-made question. Thank you!
