openai_ros example in local computer does not work.

edit

Hello. I'm trying to this openai_ros gym tutorials, not using ROS Development Studio(RDS).

I already checked that it does work in RDS following step by step. There was not problem at all.

BUT, I couldn't do this same tutorial in my local computer. It was troubled on the just first step.

If I type the following on my local command terminal,

  roslaunch gym_construct main.launch

then it shows that

 [ INFO] [1537961641.295151763, 0.348000000]: DiffDrive(ns = //): Advertise joint_states
 [ INFO] [1537961641.295818023, 0.348000000]: DiffDrive(ns = //): Try to subscribe to cmd_vel

 [spawn_turtlebot_model-2] process has finished cleanly
 log file: /home/parkbj/.ros/log/043fb95e-c180-11e8-8ab1-7085c22a655c/spawn_turtlebot_model-2*.log

And then, there is nothing happened. Gazebo has to be loaded, but NOT.

This problem is not only for local computer. It does though for RDS.

If I just type the same command in the Shell of RDS, instead of Simulations tap > Select a launch file > main.launch, then I get a exactly same result.

I want to try this tutorial in local computer to integrate a reinforcement learning part included in it with my own robot later.

However, how to do this tutorial in the local computer, not using RDS is nowhere.
Please let me know this.

FIY, the following is the all step of my trials on command terminal in local computer for doing this tutorial.

1. Download Turtlebot2Maze pkgs, and set branch.

   cd ~/catkin_ws/src
   git clone https://bitbucket.org/theconstructcore/turtlebot.git
   cd ~/catkin_ws/src/turtle
   git fetch && git checkout kinetic
   cd ~/catkin_ws
   catkin_make
   source devel/setup.bash
   

2. Download openai_ros pkgs, and set branch.

   cd ~/catkin_ws/src
   git clone https://bitbucket.org/theconstructcore/openai_ros.git
   cd ~/catkin_ws/src/openai_ros
   git fetch && git checkout kinetic-devel
   cd ~/catkin_ws
   catkin_make
   source devel/setup.bash
   

3. Download openai_examples_projects pkgs, and set branch.

   cd ~/catkin_ws/src
   git clone https://bitbucket.org/theconstructcore/openai_examples_projects.git
   cd ~/catkin_ws/src/openai_examples_projects
   git fetch && git checkout tutorials
   cd ~/catkin_ws
   catkin_make
   source devel/setup.bash
   

4. Download open_ai_gym_construct pkgs, and set branch.

   cd ~/catkin_ws/src
   git clone https://bitbucket.org/theconstructcore/open_ai_gym_construct.git
   cd ~/catkin_ws/src/open_ai_gym_construct
   git fetch && git checkout master
   cd ~/catkin_ws
   catkin_make
   source devel/setup.bash
   

5. Launch gym_construct main.launch file in command terminal.

   roslaunch gym_construct main.launch
   

6. Then, the command terminal shows this result. (This is exactly same with the result of shell in RDS)

   parkbj@parkbj-desktop:~$ roslaunch gym_construct main.launch
   ... logging to /home/parkbj/.ros/log/043fb95e-c180-11e8-8ab1-7085c22a655c/roslaunch-parkbj-desktop-4063.log
