Python — (tf/np).argmax()

python

tensorflow和numpy 中都有個argmax()

兩種用法都一樣(差別在tensorflow 要用sess.run()啟動)下面只展示numpy

用法如下

import numpy as np

arr = np.array([[1, 10, 3], [6, 5, 11], [7, 8, 9], [12, 2, 4]])

print('axis=0', np.argmax(arr, axis=0))

print('axis=1', np.argmax(arr, axis=1))# arr[0] = [1, 10,  3]

# arr[1] = [6,  5, 11]

# arr[2] = [7,  8,  9]

# arr[3] = [12, 2,  4]

結果
