numpy数组除法-/:'list'和'float'不支持的操作数类型 [英] Numpy Array Division - unsupported operand type(s) for /: 'list' and 'float'

问题描述

我定义了以下numpy数组:

I defined the following numpy array:

import numpy as np
numpy_array = np.array([[-1,-1,-1,-1,-1], [-1,2,2,2,-1], [-1,2,8,2,-1], [-1,2,2,2,-1], [-1,-1,-1,-1,-1,-1]])

现在我想将整个数组除以8:

Now I wanted to divide the whole array by 8:

numpy_array /= np.float(8.0)

我收到以下错误消息:

TypeError: unsupported operand type(s) for /: 'list' and 'float'

我希望有人对我有提示，我在做错什么.

I hope someone has a hint for me, what I am doing wrong.

推荐答案

该数组的列表大小不正确，最终列表不正确.

The array has a list of the incorrect size, the final list is incorrect.

如果要将数据保留为int，则可以使用numpy_array = np.divide(numpy_array, 8.0)，否则请参见MSeifert的答案.

if you want to keep the data as an int, you can use numpy_array = np.divide(numpy_array, 8.0), otherwise see MSeifert's answer.
