【conda】解决 An HTTP error occurred when trying to retrieve this URL.问题

 

遇到

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/genomedk/linux-64/current_repodata.json>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
ConnectionError(MaxRetryError("HTTPSConnectionPool(host='conda.anaconda.org', port=443): Max retries exceeded with url: /genomedk/linux-64/current_repodata.json (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f4cef822390>: Failed to establish a new connection: [Errno 101] Network is unreachable'))"))

原因是conda源加入了不知名的URL，现在不能使用了（或者废弃）

# 重置源配置
conda config --remove-key channels 
# 重新添加清华源
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 --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/ 
conda config --set show_channel_urls yes
# 查看效果
cat ~/.condarc
