TypeError: ‘Image‘ object does not support item assignment问题解决

通过Image库打开的图像，直接进行矩阵操作时会报错“TypeError: 'Image' object does not support item assignment”。这里，需要先将图像转换成numpy格式。

示例如下：

import numpy as np
from PIL import Image

img = Image.open('1.jpg')
img = np.asarray(img)  # to numpy

# operation
img[:, 1:10, 1:10] = 0

img = Image.fromarray(img)  # to Image
