我有一些代码,它基本上将long numpy数组的某些元素设置为零.

import numpy as np
a = np.array([[[1, 2, 3, 4], [0, 1, 2, 3], [1, 2, 3, 4]], 
              [[0, 1, 2, 3], [0, 0, 1, 2], [0, 2, 3, 4]]])

aup = a + 2

b = np.array([[[0, 1, 2], [3, 4, 5], [0, 2, 3], [5, 6, 7], [0, 1, 2]],
              [[3, 4, 5], [0, 2, 3], [5, 6, 7], [0, 1, 2], [3, 4, 5]],
              [[0, 1, 2], [3, 4, 5], [0, 2, 3], [5, 6, …
