Hi,
This error just means that you do not have rospkg package installed. Make sure your ROS installation is correct. You can also install rospkg separately http://wiki.ros.org/rospkg
it shows errors like this
File "/DRL-robot-navigation/TD3/velodyne_td3.py", line 7, in
If you are missing a package that means you do not have it installed or your sources are not set up properly. Make sure packages are installed and sourced properly. Rospkg is not part of this repo and should be part of ROS.
Hi sir , we done the training process but after that i don't know how to run the process and get the result
You can load the network parameters as explained here: https://github.com/reiniscimurs/DRL-robot-navigation/issues/17
What kind of process do you want to run and what results to you want to achieve?
while doing training process gazebo environment is not opening only rviz is opening
That is normal behaviour. Gazebo launch is turned off to save computer resources. You can start the Gazebo automatically by setting https://github.com/reiniscimurs/DRL-robot-navigation/blob/be811a4050dfcb5c800a0a0e4000be81d48cfbc5/catkin_ws/src/multi_robot_scenario/launch/empty_world.launch#L7 to true
hi sir, can you please tell me how to give movements to the robot
The movements to the robot are given by the neural network with calling the step() function in https://github.com/reiniscimurs/DRL-robot-navigation/blob/be811a4050dfcb5c800a0a0e4000be81d48cfbc5/TD3/velodyne_td3.py#L280 This executes 1 timestep in the simulation with the calculated action by the actor network.
In simulation, the robot movement is executed by a ROS publisher in https://github.com/reiniscimurs/DRL-robot-navigation/blob/be811a4050dfcb5c800a0a0e4000be81d48cfbc5/TD3/velodyne_env.py#L180
ok sir, we executed the code but the robot is staying in one place. Could you tell us how to give the destination to the robot and make the robot to move.
Please, provide specific and detailed information about your computer/software setup, installation steps, steps you took to run the program, outputs, steps you have taken to solve your issue.
It is impossible to say what is and isn't working without you providing any information.
Respected sir, I have followed all the instructions ( All the setup which is needed for the execution of the code) which was provided, and till now everything works good like the environment but the robot couldn't move and stays on the same place, i request you to like resolve my query thank you
Once again, I cannot help you if you do not provide any information about a specific problem. What exactly is happening? What have you tried? What is the terminal output? Take a look at how other people have asked questions in other issues (closed and open ones) and try to follow their example.
