尽管已安装，但仍无法加载torchvision

Question

我已经使用以下命令安装了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

我得到了：

Traceback (most recent call last):

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

  File "C:\Users\lkoefoed\AppData\Local\Continuum\anaconda3\lib\site-package\torchvision\__init__.py", line 2, in <module> 
from torchvision import datasets

  File "C:\Users\lkoefoed\AppData\Local\Continuum\anaconda3\lib\site-packages\torchvision\datasets\__init__.py", line 1, in <module> 
from .lsun import LSUN, LSUNClass

from PIL import Image

  File "C:\Users\lkoefoed\AppData\Local\Continuum\anaconda3\lib\site-packages\PIL\Image.py", line 56, in <module> 
from . import _imaging as core

ImportError: DLL load failed: The specified module could not be found.

Answer 1

通过运行以下命令修复：

conda install pytorch-cpu -c pytorch 
pip install torchvision 

删除site-package中的PIL和pillow文件夹，然后运行：

pip install pillow

Answer 2

conda：

conda install torchvision -c pytorch

这对我来说非常有效。
