【疑难杂症】解决conda镜像使用时的问题

报错

(record) C:\Users\tmf>conda install pytorch==1.10.1 torchvision==0.11.2 torchaudio==0.10.1 cudatoolkit=11.3
Collecting package metadata (current_repodata.json): failed

HTTP errors are often intermittent, and a simple retry will get you on your way.
'http://mirrors.ustc.edu.cn/anaconda/pkgs/main/win-64'

解决办法

将.condarc里面的URL的https换成http即可

啊但是！

第一次遇到问题确实像上面那样解决了，之后又遇到，这就不行了
最终还是找到了某位博主的解决方案

直接将.condarc文件修改成下面的即可：

channels:
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
