在 Windows 10 上 pip install torchvision 出错

Question

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

当我运行时 cmd 没有抱怨conda install pytorch cuda90 -c pytorch，然后当我运行时pip3 install torchvision我收到此错误消息。

有人遇到这个错误吗？

Answer 1

我尝试使用：

pip install torchvision

但它对我不起作用。所以，我更仔细地搜索了这个问题并找到了另一个解决方案：

pip install --no-deps torchvision

我希望它会有所帮助。

更新：我想补充：“--no-deps”意味着不会下载任何依赖包。

Answer 2

由于大小限制，Windows 版本的 pytorch 从未上传到 PyPi for Windows。因此，在安装时，您需要使用 -f 或 --force-link 到 PyTorch 轮：

pip install torch===1.5.0 torchvision===0.6.0 -f https://download.pytorch.org/whl/torch_stable.html

Answer 3

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。下次尝试运行所有内容pip
