Vertically add numpy array to itself

Question

I am trying to add an array of (174, 2, 2) to itself vertically. So far I am able to do it in non-numpy way:

import numpy as np
cm1 = np.random.rand(174, 2, 2)
temp_array = np.zeros([2, 2])

for _content in cm1:
    temp_array = np.add(temp_array, _content)

print(temp_array)

I am able to get the results, but is there a numpy way of doing this?

You can use sum with parameter axis=0 as:

cm1.sum(axis=0)
array([[82.39817762, 84.41947252],
       [91.82740901, 83.53547764]])
