显然，我做错了什么。在

请帮忙！在

Answer 1

如果没有GPU（仅适用于CPU），请使用以下命令：

• 1.2版： conda install pytorch==1.2.0 torchvision==0.4.0 cpu仅-c pytorch

• 对于新版本： conda安装pytorch-torchvision cpuonly-c pytorch

或者

如果您有GPU，请使用以下命令（使用您自己的CUDA版本）：

• 1.2版： conda install pytorch==1.2.0 torchvision==0.4.0 cudatoolkit=10.0-c Pythorch

• 对于新版本： conda install pytorchvision cudatoolkit=10.1-c Pythorch

最好使用anaconda命令提示符来安装pythorch，如果可能，使用python3.6。比较合适。python3.6在使用开源库方面更为稳定。您也可以在下面的链接中找到安装过程 如果需要， https://medium.com/@bryant.kou/how-to-install-pytorch-on-windows-step-by-step-cc4d004adb2a

如果你需要的话，你可以试着用这些

对于python3.6:

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m- win_amd64.whl
pip install torchvision

对于python3.7:

我认为Conda在开源库安装中比pip更好
