华为云 ARM 服务器（鲲鹏）基本使用（Ubuntu 系统）

目录

1. 换源
2. 安装 pip 和 常用 python 库
3. cpu info

选了默认的 ubuntu 18.04 系统结果默认的 apt 源没法用。

可以直接换成 清华源，但是注意要使用 ports 镜像，这是是为 arm 架构系统准备的，不能使用普通的 apt 源。

换源

清华源 https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/

直接编辑 vi /etc/apt/sources.list

可以直接用命令替换

:%s/ports.ubuntu.com/mirrors\.tuna\.tsinghua\.edu.cn/g

也可以备份原文件后，重写文件内容为：

我也不知道为啥这么多，我是直接替换的。

安装 pip 和 常用 python 库

apt install python3-pip

虽然装了 pip 但是用 pip 装 numpy 会失败，可能还是源的问题。

所以用 apt 安装 numpy

apt install python3-numpy

tqdm，jupyter 可以用 pip 装，但是 sklearn 也不行

apt install python3-sklearn
