在Anaconda3中使用清華源的方法：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

在Windows10修改清華源，詳細步驟請看Anaconda3使用清華源。

Ubuntu 的軟體源配置檔案是 /etc/apt/sources.list。將系統自帶的該檔案做個備份，將該檔案替換為下面內容，即可使用 TUNA 的軟體源映象。

$ sudo gedit /etc/apt/sources.list
