I'm using Docker to run the project because my local machine uses ROS2. Will this cause any problems? I was able to run other projects (FAST-LIO) before without issues.
Below is my directory structure.

Will the name make a difference? The host machine is called "dynamicgap_ws" and the Docker container is called "arena_ws".

@kunshaoxiansheng Thank you for trying out the repo! I don't think the workspace name should cause any major problems.

You can control the visualization of RViz and Flatland through the headless argument in start_arena.launch. The argument's default value does not bring up any visualization, but you can set it to 0 (RViz + Flatland) or 1 (RViz only, no Flatland) depending on what you want to see. You can also plug in the custom RViz file in dynamic gap if you would like to visualize some dynamic gap-specific topics. Let me know if this helps!

[kunshaoxiansheng]

I have changed the 'headless' setting to 0 in the launch file, but I'm still getting this error.

@kunshaoxiansheng RViz looks OK from my end with headless set to 0. It's possible you need to enable docker to run with a GUI, you can see instructions here. Are you able to run just rviz by itself?
