尽管已安装 Torchvision，但仍无法加载它

Question

我已经使用以下方法安装了 pytorch 和 torchvision：

conda install pytorch-cpu -c pytorch
pip install torchvision

当我尝试在 spyder 中运行以下命令时：

import torch
import torchvision
import torchvision.transforms as transforms

我得到：

Traceback (most recent call last):

  File "<ipython-input-2-0bf25e9dac67>", line 2, in <module>
    import torchvision

通过运行修复：

conda install pytorch-cpu -c pytorch 
pip install torchvision 

删除site-packages中的PIL和pillow文件夹，然后运行：

pip install pillow
