1.安装ubuntu16.04.1，并且安装vmtools，设置电源选项
2.更新清华源
cd /etc/apt/
sudo cp sources.list sources.list.bak 备份
sudo gedit sources.list
改变内容：
# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

deb http://cn.archive.ubuntu.com/ubuntu bionic-security main multiverse restricted universe
deb http://cn.archive.ubuntu.com/ubuntu bionic-proposed main multiverse restricted universe
sudo apt-get update 更新源
sudo apt-get upgrade 更新软件
3.更新python至3.5
sudo apt-get install python3 安装python3，下载的Python程序被安装在usr/local/python3.5
sudo cp /usr/bin/python /usr/bin/python_bak 备份2.7
sudo rm /usr/bin/python 删除2.7链接
sudo ln -s /usr/bin/python3.5 /usr/bin/python 指向新链接
切换回2.7
1sudo rm /usr/bin/python
2sudo ln -s /usr/bin/python2.7/usr/bin/python
----------------------------------------------------------------------------------------
python3.6
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
调整Python3的优先级，使得3.6优先级较高
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
更改默认值，python默认为Python2，现在修改为Python3
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
如果要切换到Python2，执行：
sudo update-alternatives --config python
3.安装Anaconda，gym和tensorflow
去https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/下载anaconda3_4.3.0-linux-x86_64.sh
bash Anaconda3-4.3.0-Linux-x86_64.sh 关闭重开ter
conda create --name gymlab python=3.6创建虚拟环境为gymlab
激活环境
source activate gymlab
sudo apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb libav-tools xorg-dev python-opengl libboost-all-dev libsdl2-dev swig
sudo apt install git
git clone https://github.com/openai/gym.git
cd /gym
python -m pip install --upgrade --force pip
注释setup.py
#'mujoco': ['mujoco_py>=1.50', 'imageio'],
#'robotics': ['mujoco_py>=1.50', 'imageio'],
pip install -e '.[all]'
pip install setuptools==33.1.1
sudo apt-get update
python3 -m pip install aiohttp
python3 -m pip install --upgrade pip
git clone https://github.com/openai/mujoco-py
cd mujoco-py
pip install -e . --no-cache
4.安装tensorflow
安装pip和依赖包
sudo apt-get install python3-pip python3-dev
pip install --upgrade pip
pip3 install tensorflow（cpu版本）
pip3 install --upgrade tensorflow-gpu（gpu）
测试
$python
$import tensorflow
5.ubuntu16.04版本 the system is running in low-graphics mode问题
cd /etc/X11
sudo cp xorg.conf.failsafe xorg.conf
sudo reboot
sudo apt-get update 更新源
sudo apt-get upgrade 更新软件
进入etc/X11文件夹指令删掉xorg.conf里面内容
