python - 我如何调用整数的 np.zeros？

Question

Musica = np.zeros((row*120,3))

for k in range(21, 90):
    for i in range(row):
        for j in range(Max[k], Min[k]):
            Musica[i*120 + j,:] = 0,i,j
            if np.all(data[i*col + j,:]==(255.000,0.000,0.000,i,j)):
                Music[i*120 + j,:] = 1,i,j

Max[k] 和 Min[k] 是属于数学整数组的数字，但我从 python 得到这条消息

"TypeError: range() integer end argument expected, got numpy.float64."

如何调用整数类型的np.zeros？

现在我正在尝试使用以下代码:

Musica = np.zeros((row*120,3))

for k in range(21, 90):
    for i in range(row):
        Max = int(Max[k])
        Min = int(Min[k])
        for j in range(Max, Min):
            Musica[i*120 + j,:] = 0,i,j
            if np.all(data[i*col + j,:]==(255.000,0.000,0.000,i,j)):
                Musica[i*120 + j,:] = 1,i,j

我收到的错误信息是:

Traceback (most recent call last):

  File "<ipython-input-115-4aef2441146c>", line 1, in <module>
    runfile('C:/Users/Arthur_USP/Desktop/Informação/Nova abordagem/untitled0.py', wdir='C:/Users/Arthur_USP/Desktop/Informação/Nova abordagem')

    execfile(filename, namespace)

  File "C:/Users/Arthur_USP/Desktop/Informação/Nova abordagem/untitled0.py", line 181, in <module>

TypeError: 'int' object has no attribute '__getitem__'

第 181 行是“Max = int(Max[k])”

Answer 1

你可以试试 np.zeros(shape).astype(int)。

编辑:实际上，zeros 接受 dtype 参数。所以更好的是 np.zeros(shape, dtype=int)
