ubuntu16 安装gym-gazebo

目录

本节会安装以下内容

  • Kinetic

  • ubuntu16

  • gazebo8

  • gym

  • python3.5

  • opencv3

  • 安装 gazebo_ros_pkgs

  • gym-gazebo

  • gym-gazebo 测试

本节笔记主要记录ubuntu16 下安装gym-gazebo，包括其依赖的软件包安装。

我的代码仓库: https://github.com/porterpan/gym-gazebo

建议直接clone 我的软件仓库安装(直接适应kinetic版本安装不会出现警告和编译出错终止，当然可能会应为你的ros功能包缺失出错,这时只需要手动安装缺失的ros功能包，删除catkin_ws，再重复上次的安装过程即可)

cd ~
git clone -b master https://github.com/porterpan/gym-gazebo

实在官方的仓库中修改了: ~/gym-gazebo/gym_gazebo/envs/installation/gazebo.repos 文件内容.使整个安装适应ROS kinetic 环境。当然过程中如果缺ros功能包，需要自己额外安装功能包的。

缺失ros功能包会在编译时出现make error 红色的， 解决办法见ROS 中功能包的安装与查询 部分的方法安装好，然后remove -rf 安装路径中的catkin_ws 文件夹，然后重新上一步操作安装即可。

第一部分安装gym-gazebo

下载安装文件

cd ~ #进入home目录
git clone -b master https://github.com/porterpan/gym-gazebo

安装依赖环境

Basic requirements:

  • ROS Kinetic (/rosversion: 1.12.7) (安装选择这个sudo apt-get install ros-kinetic-desktop, 不要全装不然后面装gazebo8会相对麻烦点)

进入ROS官网的安装界面：http://wiki.ros.org/ROS/Installation

选择需要的版本 Kinetic 和系统平台，我们用的是 ubuntu 16.04 按照指导进行安装，这里注意要选择安装 ros-kinetic-desktop 版本，不要选 ros-kinetic-desktop-full，前者不包含 Gazebo ，后者包含了 Gazebo 7。后边安装 Gazebo 8 的时候还需要卸载掉，比较麻烦。 按照完 ROS 测试一下，在命令行中输入如下命令，看能否正常启动 ros master ：

前边安装的 ROS 与 Gazebo 是完全独立的两部分，要使他们之间互相通讯，还需要安装 gazebo_ros_pkgs 包。

进入官网安装界面：http://gazebosim.org/tutorials?tut=ros_installing

按照指导安装即可。我一般选择用 A: Install Pre-Built Debians 方式安装。需要注意的是，如果用如下命令安装报错：

sudo apt-get install ros-kinetic-gazebo-ros-pkgs ros-kinetic-gazebo-ros-control

则需要指明 Gazebo 版本，将命令改为：

sudo apt-get install ros-kinetic-gazebo8-ros-pkgs ros-kinetic-gazebo8-ros-control

就可以解决问题。

测试。安装结束，用如下命令测试：

roscore  # 启动 ros master
rosrun gazebo_ros gazebo  # 用 rosrun 方式启动 Gazebo

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"

安装gym-gazebo

cd ~
Gazebo gym
git clone -b master https://github.com/erlerobot/gym-gazebo
cd gym-gazebo
sudo pip2 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

Try it out (turtlebot simple env)

  • Issues:

spacenav_node not compiling. CATKIN_IGNOREd. wiimote not compiling. CATKIN_IGNOREd. kobuki_qtestsuite not compiling. CATKIN_IGNOREd.

Agent dependencies:

# make sure to switch to bash, because the installation script 
# hasn't been converted to ZSH yet
# and if you run it from ZSH the environmental variables 
# that are set during the script's execution aren't preserved
cd gym_gazebo/envs/installation
./setup_kinetic.bash    
./turtlebot_setup.bash

Run the environment with a sample agent:

# only execute this while still in the same bash as last step
cd ../../../examples/scripts_turtlebot/
python circuit2_turtlebot_lidar_qlearn.py

The result should look like this (after a few seconds):

... (messages about ROS and Gazebo starting up, until finally:) ...

第二部分：附录

ROS 中功能包的安装与查询

1.查询当前安装完成的所有包文件

 rospack  list

  • 可以看到所有的ROS功能包都在/opt/ros/kinetic/share目录下，所以也可以使用如下命令查询

    cd /opt/ros/kinetic/share/
or
roscd turtlesim/
cd ..

    2.查询ros的所有功能包

    apt-cache search ros-kinetic

  • 或者说在不知道要安装功能包的确切名字的情况下找到目标包

    apt-cache search ros-kinetic | grep rqt-

    通过管道线 与grep命令， 输出与关键字rqt-相关的行

  • 再或者下述安装命令与Tab键结合

    sudo apt-get install ros-kinetic-rqt-

    系统输出相应提示。 前述所有内容中，rospack list 与sudo apt-get install ros-kinetic-rqt- +Tab键使用最方便。

安装错误解决

错误1：

  • 错误1：错误提示：

    在moveit编译时找不到manipulation_msgsConfig.cmake manipulation_msgs-config.cmake文件

    ```bash Could not find the required component 'manipulation_msgs'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found. CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by "manipulation_msgs" with any of the following names:

    manipulation_msgsConfig.cmake manipulation_msgs-config.cmake

![manipulation_msgsconfig.cmake](./image4/manipulation_msgsconfig.cmake)

- 错误1：解决：

搜索这个功能包

![manipulation_msgsconfig.search](./image4/manipulation_msgsconfig.search.png)

能找到这个ros-kinetic-manipulation-msgs 包
```bash
sudo apt-get install ros-kinetic-manipulation-msgs

对ros安装对应的manipulation_msgsConfig包, 完成安装后重新去编译一下你的moveit包就行了。

问题2

  • 错误二：错误提示：

" CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by "tf2_geometry_msgs" with any of the following names:

tf2_geometry_msgsConfig.cmake
tf2_geometry_msgs-config.cmake

Add the installation prefix of "tf2_geometry_msgs" to CMAKE_PREFIX_PATH or set "tf2_geometry_msgs_DIR" to a directory containing one of the above files. If "tf2_geometry_msgs" provides a separate development package or SDK, be sure it has been installed."

  • 错误二：解决：

先搜索这个需要安装的ros功能包

apt-cache search ros-kinetic | grep tf2_geometry_msgs

发现存在这个包

porter@porter-Aspire:~/gym-gazebo/gym_gazebo/envs/installation$ apt-cache search ros-kinetic | grep tf2_geometry_msgs
ros-kinetic-tf2-geometry-msgs - tf2_geometry_msgs

执行这个功能包的安装

问题3：

  • 问题3：解决

出现这个错误的原因是ecl升级，或这和你当前安装的ros版本不对应。造成了cmake版本比配。出错，方法是

打开gazebo.repos,修改如下部分：

ecl_lite: 
type: git 
url: https://github.com/stonier/ecl_lite 
version: release/0.61-indigo-kinetic 
ecl_navigation: 
type: git 
url: https://github.com/stonier/ecl_navigation 
version: devel 
ecl_tools: 
type: git 
url: https://github.com/stonier/ecl_tools 
version: release/0.61-indigo-kinetic

(将ecl_core、 ecl_lite 和ecl_tools 的版本号（version）改成： release/0.61-indigo-kinetic）

不过最终解决还是建议你如果也是安装ros kenitic 直接复制我后面附录的gazebo.repos内容替换掉之前的

路径：

vim ~/gym-gazebo/gym_gazebo/envs/installation/gazebo.repos

gazebo.repos　内容修改
