1 显示channel：

首先，conda config --show能够显示出所有conda的config信息。

如果只是想看channel的信息，直接在后面机上channel即可conda config –show channels：

C:\Users\mcj&gt;conda config --show channels
channels:
  - defaults

C:\Users\mcj>conda config --show channels

channels:

- defaults

一个默认源。

2 增加channel

根据官网提示，添加以下两个源(新增一个pytorch源)：

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --set show_channel_urls yes

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/

conda config --set show_channel_urls yes

conda config –set show_channel_urls yes的意思是从channel中安装包时显示channel的url，这样就可以知道包的安装来源了。

3 删除channel

上面三个源中，conda-forge不可用，因此，我们需要删除这个channel，输入：

conda config --remove channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

1	conda config --remove channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

这时，这个源就被删除了。

C:\Users\mcj&gt;conda config --show channels
channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - defaults
