CONDA modifying a mirror source

1. Add Tsinghua view image source

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

Add the currently available image source of CUHK

conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/

For specific modified files, see create in the current user directory .condarc file , You can view the changes of the contents of the file before and after the source change .
2. Restore the original image

conda config --remove-key channels

3. delete mirror

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

4. There's a problem later
2022 Use this link again later , I found the wrong report . Wrong report ！ therefore , Check information , Read the blogs of the following two bigwigs , To discover the mystery .
（1）Anaconda Create a new environment , appear CondaHTTPError: HTTP 000 CONNECTION FAILED for url … To solve the process
（2）conda Add image source _conda Add domestic sources correctly
therefore , The modified code is as follows ：

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/win-64/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64/
conda config --set show_channel_urls yes

5.conda Common commands

conda create -n your_env_name python=3.6
conda activate  Environment name 
conda deactivate 
conda clean --all # Delete cache 
conda config --show # View the installed image source 
conda config --remove channels url    # Delete image address url
conda remove -n rcnn --all  Delete environment 

6. Rename environment
conda There's no rename command , Renaming is achieved by clone Accomplished .
First step ： First clone One copy new name Environment

conda create -n tf --clone rcnn

The second step ： Delete old Environmental Science

conda remove -n rcnn --all
conda info -e  # see conda Environmental Science
