如何安装OpenGym

折腾了好久，终于装上了。记录一下。

anaconda环境安装OpenGym

1. 创建环境conda create --name gymlab python=3.5注意官方不支持3.5以上的python
2. 安装gym依赖
   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
3. 安装gym

git clone https://github.com/openai/gym.git
cd gym
pip install -e '.[all]'

安装过程中 mujoco_py会各种出错，不用管。不管怎么装，只要用pip装的绝对会出错。

4. 安装mujoco_py

#获取mujoco:
    wget -O mjpro150.zip https://www.roboti.us/download/mjpro150_linux.zip
    sudo apt-get install unzip
    rm -rf ~/.mujoco
    mkdir ~/.mujoco
    unzip mjpro150.zip -d ~/.mujoco/mjpro150
    rm -rf mjpro150.zip
    #把你的许可文件放进这里~/.mujoco/mjkey.txt" mujoco不是一个免费的软件，但是有edu邮箱的话可以申请一年免费试用
#install-mujoco-dependencies: 安装mujoco_py的依赖
    sudo apt-get update -q
    DEBIAN_FRONTEND=noninteractive sudo apt-get install -y \
    curl \
    git \
    libgl1-mesa-dev \
    libgl1-mesa-glx \
    libosmesa6-dev \
    python3-pip \
    python3-numpy \
    python3-scipy \
    unzip \
    vim \
    wget \
    xpra \
    xserver-xorg-dev
    sudo apt-get clean
    sudo rm -rf /var/lib/apt/lists/*
# install patch
    sudo curl -o /usr/local/bin/patchelf https://s3-us-west-2.amazonaws.com/openai-sci-artifacts/manual-builds/patchelf_0.9_amd64.elf
    sudo chmod +x /usr/local/bin/patchelf

#install-mujoco:安装mujuco_py
    git clone https://github.com/openai/mujoco-py.git
    cd mujoco-py && source activate gym && python setup.py install"

至此，安装成功。
