Anaconda3 安装pytorch出错：

conda install pytorch                         1 
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): | - failed

　　解决办法：

　　conda config --add channels conda-forge

　　conda config --set channel_priority strict

　　conda config --set channel_priority flexible

　　

　　直接我还用了

　　conda clean -a

　　conda clean -p

 

　　安装conda install pytorch

conda install pytorch
