图片不会在谷歌 Colaboratory 中使用 PIL 从响应对象中打开

Question

我正在学习 Udemy 上的“用于深度学习和计算机视觉的 PyTorch”课程，并按照说明将代码输入 Google Colaboratory。

但是，有一部分代码是 PIL 用于从响应对象中读取图像，但我有一个错误“AttributeError: can't set attribute”

我在 python 3.6 上使用枕头 4.0.0 我尝试将 resonse.raw 更改为 response.content、response.text 和只是响应。我尝试删除 stream = True 属性，并尝试将 url 直接输入到 Image.open 方法中

!pip3 install pillow==4.0.0

import PIL.ImageOps

import requests
from PIL import Image

url = 'https://c8.alamy.com/comp/DYC06A/hornless-reindeer-at-zoo-DYC06A.jpg'
response = requests.get(url, stream = True)
img = Image.open(response.raw)
plt.imshow(img)

我希望在 url 变量中包含带有 url 的鹿图像的情节。

相反，我收到此错误消息：
