By | October 19, 2019

Add and remove some anaconda channels may be the first thing you have to do after you have installed anaconda, because the default channel may be very slow in some locations when you plan to install python libraries by anaconda. In this tutorial, we will introduce how to add and remove anaconda channels for anaconda beginners.

Add and remove anaconda channels with configure file

The most easy way to add and remove anaconda channels is to edit anaconda configure file.

Anaconda configure file is called ‘.condarc‘, you can find this file in your user home path.

If you can not find it, we advice you to use Eeverything application to search.

anaconda configure file path

Open .condarc file

If you want to add a channel, you can add a url in channels:

channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - defaults
show_channel_urls: true
ssl_verify: true

If you want to remove a channel, you can delete a channel url.

Save .condarc file.

Add and remove anaconda channels by conda command

We also can use conda config –add channels to add a channel.

Here is an example.

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

If you want to remove a channel, we can use conda config –remove channels command.

Here is an example.

conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
