WebJun 26, 2024 · Similarly, for the second column, the values are 2 and 6, so the max value index is 1. For the third column, values are 3 and 2, so the max value index is 0. That’s why we are getting the output as an array ( [0, 1, 0]). For axis = 1, the first row values are (4, 2, 3), so the max value index is 0. Web1.
