更换软件换源

参考：anaconda | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

1. 打开anaconda prompt
2. 执行 conda config --set show_channel_urls yes
3. 用户目录 C:\Users{yourname}\下出现 .condarc文件
4. 修改该文件

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

5. 运行 conda clean -i清除索引缓存，保证用的是镜像站提供的索引

安装配置步骤

1. 下载Minicondahttps://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/
2. 配置环境变量

   ​{安装路径}\Miniconda3;
   {安装路径}\Miniconda3\Scripts;
   {安装路径}\Miniconda3\Library\bin;​
   

在pycharm的终端中使用自建虚拟环境

C:\Program Files\PowerShell\7\pwsh.exe -ExecutionPolicy ByPass -NoExit -Command "& 'E:\CodeTools\Miniconda3\shell\condabin\conda-hook.ps1' ; conda activate  python37 "

卸载

conda install anaconda-clean
anaconda-clean --yes
sudo rm -rf <miniconda_install_dir>
