1、概览
anaconda更换速度更快、更稳定的下载源，在linux环境测试通过。
2、conda源查看
在修改之前可以查看下现有conda源是什么，查看conda配置信息，如下：
cat ~/.condarc可以看到你的conda源，以我的conda源举例：
show_channel_urls: true
channels:- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main- defaults其中，show_channel_urls表示下载时展示下载通道，channels中每项表示目前已配置的conda源（上述示例为清华源）。最后的defaults表示conda默认的官方源，如果尝试前5个源失败后，则会继续尝试在官方源下载，如果网速可以，defaults可以保留，反之建议删除defaults（可以vim ~/.condarc 进行修改）。
如果你创建虚拟环境出现如下内容，则建议删除defaults
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/linux-64/current_repodata.json>3、conda清华源配置
配置前可通过如下命令清除原conda源
conda config --remove-key channels清除后可以通过cat ~/.condarc 查看一下源，确保清除成功。
然后执行如下命令添加conda源：
conda config --set show_channel_urls yes
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
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/r
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2将上述命令复制到终端即可，运行无结果输出，无报错。然后查看condarc就可以看到conda源均被更新为如下样式，注：确保5个链接均添加，否则会出现找不到包
show_channel_urls: true
channels:- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main然后我们创建虚拟环境试一下，conda create -n py310 python=3.10.0 ，可以看到虚拟环境可正确创建，同时如果看到内容(Solving environment: unsuccessful attempt using repodata from current_repodata.json, retrying with next repodata source.)，表示conda在通过每个conda源拉取包创建虚拟环境，输出如下：
Collecting package metadata (current_repodata.json): done
Solving environment: unsuccessful attempt using repodata from current_repodata.json, retrying with next repodata source.
