原代码报错index 22933 is out of bounds for axis 1 with size 22933

def test_frequency():
    wordlist = [['apple'], ['apple', 'apple'], ['tree', 'water'], ['argue', 'apple','apple','tree','tree','tree']]
    totallist = ['apple', 'tree', 'argue', 'water']
    arr = np.zeros(shape=(4, 4), dtype=int) 

    i = 0
    for line in wordlist:

        n = list(Counter(line).keys())
        v = list(Counter(line).values())
        j = 0
        m = 0
        for elem in totallist:
            if elem in n:
                arr[i, j] = v[m]  
                m += 1
            j += 1

        i += 1

    print(arr)

缩减矩阵规模，可以运行。

循环语句数组越界了，
