推荐答案

您可以使用matplotlib读取图像，然后将其另存为文件

You can use matplotlib to read the image and then save it as a file

In [21]: import json
In [22]: from matplotlib import image

In [23]: f = open("out.json", "w")

In [24]: c = image.imread("02.jpg")

In [25]: f.write(json.dumps(c.tolist(), indent=4))
Out[25]: 10925444

In [26]: f.close()
