json.load 接受打开的文件,而不是文件路径。

data = json.load(open('movie_acotrs_data.txt'))

可能最简洁的方法是使用 2D convolution :

In [1]: import numpy as np
In [2]: from scipy.signal import convolve2d
In [3]: kernel = np.array([[0, 1, 0],
   ...:                    [1, 1, 1],
   ...:                    [0, 1, 0]])
   ...:
In [4]: grid = [[ 0,  1,  2,  3],
    ...:         [ 4,  5,  6,  7],
    ...:         [ 8,  9, 10, 11],
    ...:         [12, 13, 14, 15]]
    ...:

In [5]: convolve2d(grid, kernel, mode='same')
Out[5]:
array([[ 5,  8, 12, 12],
       [17, 25, 30, 27],
       [33, 45, 50, 43],
       [33, 48, 52, 40]])
