Ubuntu16.04LTS下搭建强化学习环境gym

1.安装Anaconda

去清华镜像下载anaconda3_4.3.0-linux-x86_64.sh，然后在终端中输入以下命令进行安装：

cd downloads
bash anaconda3_4.3.0-linux-x86_64.sh

2.创建虚拟环境

//gymlab是自己起的虚拟环境名称 python=x.y指定python版本
conda create --name gymlab python=3.5

3.安装gym

先重新打开一个终端，然后遵循以下步骤：

source activate gymlab
pip install gym[all]

2

这一步可能会出错
比如：提醒pip版本低，使用如下命令更新：

python -m pip install --upgrade pip
1

继续安装，不出意外，还会报错：
Failed building wheel for mujoco-py

这个需要自行安装一下mujoco，可以参考这个方法：
Mujoco以及mujoco_py的安装
安装完成之后，重新执行：

pip install gym[all]

保持网络畅通，等待安装完成，看到如下信息，说明安装完成。
