錯誤描述
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.
是在創建conda新環境的時候出現的: conda create -n myEnvironmentName python=3.7
PS:如果是安裝依賴包不使用pip install, conda安裝博不太友好..
問題解決：
(這個方法對我有效，不知道對你有沒有效)
1. 終端打開conda配置文件gedit .condarc
2.刪除原文件內容並替換為下面的:
1 channels: 2 - defaults 3 show_channel_urls: true 4 default_channels: 5 - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main 6 - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free 7 - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r 8 custom_channels: 9 conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud 10 msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud 11 bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud 12 menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud 13 pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud 14 simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
