Hello.These codes were removed by me:

But there's still this in the topic: 3cef63c48bc18c4bf7442fa0ada6d0a6 I run "multi_robot_scenario.launch" directly after "catkin_make_isolated" and "source devel_isolated/setup.bash". What is the reason for this?

Have you also removed the subscriber to this topic? https://github.com/reiniscimurs/DRL-robot-navigation/blob/main/TD3/velodyne_env.py#L126

Most likely, this is where this topic is coming from.

Hello, one more question, I haven't seen everything related to the /scan topic, but why does this topic exist? It feels like a strange situation. I've tried restarting vscode and the computer, but it doesn't seem to help. image image image image image

There is no /scan topic in the original code. That must be something that you have added with your changes.

You should use the search functions in your IDE to find the source of your topic.
