配置apt源

  • 配置前查看环境信息 ```shell
  1. 查看系统信息 lsb_release -a 显示： Distributor ID: Ubuntu Description: Ubuntu 18.10 Release: 18.10 Codename: cosmic

% 这里尤其注意cosmic为18.10对应的代码名 % 所以配置apt源也要使用一样的源（cosmic） %Ubuntu 16.04代号为：xenial %Ubuntu 17.04代号为：zesty %Ubuntu 18.04代号为：bionic %Ubuntu 19.04代号为：disco %Ubuntu 20.04代号为：focal

  2. - 开始配置
  3. ```bash
  4. # 配置apt源 
  5. cd /etc/apt
  6. sudo gedit sources.list
  7. sudo apt-get update

推荐阿里源：https://developer.aliyun.com/mirror/

使用Aptitude安装

  1. % aptitude可以比apt-get更加智能地解决依赖问题，先安装它：
  2. % 有些傻逼apt-get install 会让你递归安装依赖项 
  3. sudo apt-get install aptitude
  5. sudo aptitude install build-essential
  6. %注意提示 yes or no
  8. 参考：https://jingyan.baidu.com/article/363872ec15f0006e4ba16f96.html

安装Python环境

  1. % 不一定要用编译安装
  2. % 18.10自带python3
  4. % 查看python3位置
  5. which python3 
  7. % 直接安装pip3
  8. sudo apt-get install python3-pip
  10. % pip3 install xxx

基本信息查看

1. 查看linux版本
cat /proc/version
或：uname -a

2. 查看cuda/cudnn版本
cuda 版本
cat /usr/local/cuda/version.txt
或：nvcc -V

cudnn 版本
