numpy中的三维数组

Question

如何在 numpy 中嵌套 for 循环后打印 3d 数组中的值。

import numpy as np 
center = 5
dim = 2
Bgr = 4

x = np.ones(dim)
y = np.zeros(dim)
z = np.ones(dim)
A =np.array(np.ones((dim,dim,dim)))*Bgr
for i in x:
    for j in y:
        for k in z: 
            print(A([[i],[j],[k]]))

类型错误：'numpy.ndarray' object 不可调用

Answer 1

您可以使用len(np_array)或np_array.shape[0]来获得否。 行数，然后迭代

for i in range (len(x)):
    for j in range(len(y)):
        for k in range(len(z)): 
            print(A[i][j][k])
