AI平台的环境初始配置

最近学校新上线了AI平台，由于其开发环境每次重新启动的时候需要重新配置环境，每次都去查网上的教程太麻烦了，还是自己写个博客记录一下吧~

一、pip安装package报错：Failed to establish a new connection: [Errno -3] Temporary failure in name resolution

解决方法：修改 /etc/resolv.conf 文件，在该文件尾添加如下代码：

nameserver 8.8.8.8

二、解决apt命令无法使用的问题

1.首先，备份系统的源文件sources.list:

cd /etc/apt
sudo cp sources.list sources.list.backup

2.清空源文件：

sudo vim sources.list
ggdG

3.替换文件内容：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

4.更新apt

sudo apt update
sudo apt upgrade
