搞了好几天，最后找到几个博客说虚拟机压根装不了GPU，何谈使用cuda与cudnn，想起来也是的。虚拟出来的卡怎么用
解决方法-双系统，
下面是新建虚拟机的常用的配置
=============软件更新111111111111111111111111111111111111
软件更新下载源
=》
sudo apt-get update
sudo apt-get upgrade
sudo apt install net-tools
=》
和windows相互复制（虚拟机）
sudo apt install open-vm-tools
sudo apt insatll open-vm-tools-desktop
=>
重启生效
=》sudo passwd root 凡是用超级管理员，就直接输入su
=============ubuntu修改镜像源2222222222222222222222222222222222222222

sudo apt-get update更新软件列表，换源完成
============ubuntu_ananconda安装333333333333333333333333333333333333
安装包
=》
安装 bash Anconda3.8-Linux-x86_64.sh
=>
打开终端，sudo gedit ~/.bashrc
=》
在最低下输入export PATH=“/home/rgd/anacoda3/bin:$PATH”
=>保存
终端输入，source ~/.bashrc
便可以解决终端每次打开都进入conda的base环境的问题
conda config --set auto_activate_base false
创建新环境：
conda create -n xxx python=版本号
列出所有环境
conda env list
===========ubuntu修改pip下载源4444444444444444444444444444444444444444
在home/rgd 下创建文件夹 mkdir .pip
=>
cd .pip，进去创建文件 touch pip.conf
=>
getdit pip.config
=>输入内容保存
