Windows 10上pip安装torchvision时出错

Question

在pytorch上，在Windows 10、conda和Cuda 9.0上安装。

当我运行conda install pytorch cuda90 -c pytorch时，cmd没有抱怨，当我运行pip3 install torchvision时，我得到了这个错误消息。

有人发现这个错误吗？

Answer 1

我试着用：

pip install torchvision

但对我没用。 所以，我更仔细地搜索了这个问题，找到了另一个解决方案：

pip install --no-deps torchvision

我希望这会有帮助。

更新： 我想添加：“--no deps”意味着不下载依赖项包。

Answer 2

通过运行以下命令修复它

pip3 install http://download.pytorch.org/whl/cu90/torch-0.4.0-cp35-cp35m-win_amd64.whl

pip3 install torchvision

这奇怪地解决了这个问题。不知道为什么。下次只要试着在pip上运行所有内容
