1.19 gym_gazabe安装配置

本文主要记录gym_gazebo安装的过程，想想每次安装都要一堆的百度，过程很痛苦，所以直接记录下我成功安装的过程，方便后面安装的参考。

解决ubuntu 中安装 gym_gazabe 遇到的各种水土不服

Basic requirements:

ROS Kinetic (/rosversion: 1.12.7)
Gazebo 8.1.1
Python 3.5.2
OpenCV3, installed from sources for Python 3 (git clone https://github.com/Itseez/opencv.git)
OpenAI gym

这部分的安装请自行百度, 但是这部分的内容也要安装上，不然安装gym_gazebo会出错的。

ROS Kinetic dependencies

Install Sophus

cd
git clone https://github.com/stonier/sophus -b release/0.9.1-kinetic
cd sophus
mkdir build
cd build
cmake ..
make
sudo make install
echo "## Sophus installed ##\n"

Gazebo gym

cd 
git clone https://github.com/erlerobot/gym-gazebo
cd gym-gazebo
sudo pip3 install -e .

Dependencies and libraries

sudo pip3 install h5py
sudo apt-get install python3-skimage

# install Theano
cd ~/
git clone git://github.com/Theano/Theano.git
cd Theano/
sudo python3 setup.py develop

#install Keras
sudo pip3 install keras

Agent dependencies

这部分的安装可以参考我的github 仓库(gazebo.repos 已经修改过,并且在ubuntu16上正确编译安装通过，可以直接clone下来安装,我只修改了gazebo.repos,设置/usr/local/python3.5环境):

这部分的安装需要注意请尽量用"/usr/local/bin/python3.5"如果用anaconda的python环境下安装，会出现Cmake 报错,如果你有解决的办法可以忽略提示

切换python 环境，只需要执行如下命令：

vim ~/.bashrc
# 修改弹出的文本，将export anaconda这行注释掉，如下所示
# added by Anaconda3 4.2.0 installer
#export PATH="/home/porter/anaconda3/bin:$PATH"

效果如下：

安装前需要配置下Agent 的gazebo.repos
cd ~/gym-gazebo/gym_gazebo/envs/installation/
cp ./gazebo.repos ./gazebo.repos.bak
gedit ~/gym-gazebo/gym_gazebo/envs/installation/gazebo.repos
gazebo.repos 内容如下
主要修改一些github 仓库对应版本release的分支问题, 解决安装时的错误，修改后的内容如下：

具体的修改地方建议，通过code compare 工具查看，这里推荐一个好用而代码比较工具：Meld Diff 比较好用。

接下来执行如下Agent dependences

cd gym_gazebo/envs/installation
bash setup_kinetic.bash

Run the environment with a sample agent

cd gym_gazebo/examples/scripts_turtlebot
python circuit2_turtlebot_lidar_qlearn.py
