ubuntu更换apt源、pip源和conda源

​ 在配置深度学习环境，下载安装包时，主要会使用apt源、pip源和conda源这三个进行包的下载。

一、更换apt源

​ 1.1、存放apt源的配置文件路径为/etc/apt/source.list，首先要对这个配置文件进行备份，备份命令如下。

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

​ 如果需要恢复原来的配置文件，只需要用备份的配置文件覆盖原来的配置文件即可，命令如下。

sudo cp /etc/apt/sources.list.bak /etc/apt/sources.list

​ 1.2、使用gedit打开source.list文件，命令如下。

sudo gedit /etc/apt/sources.list

​ 打开界面如下，删除其中的内容，将阿里云镜像源粘贴在其中，点击保存。

​ 不同版本的ubuntu系统，所粘贴的镜像源内容有所不同。

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

​ 1.3、最后更软件源，完成配置apt源。

sudo apt-get update

二、更换pip源

​ 豆瓣的pip源较快，建议使用。

​ 2.1、在用户路径下创建.pip/pip.conf文件，因为执行pip命令时，会先运行~/.pip/pip.conf文件，命令如下。

mkdir ~/.pip
sudo gedit ~/.pip/pip.conf

​ 将下面的命令添加到pip.conf文件中，点击保存，即可。

[global]
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com

​ 界面如下：

三、更换conda清华源

​ conda命令运行时，会先运行~/.condarc配置文件。

​ 3.1、使用gedit打开.condarc。

sudo gedit ~/.condarc

​ 3.2、进入链接https://mirror.tuna.tsinghua.edu.cn/help/anaconda/，将下面图片中的信息，全部复制粘贴到.condarc中，点击保存，成功更换为conda清华源。
