Hello, I recently started to use ROSDS for developing.
I referred to Live Class #81, for Reinforcement Learning, and I tried spawning the turtlebot2 with empty_world.( I did start sumulation, not choose launchfile)
But I’ve failed to bring the turtlebot model; it seems I don’t have that file in my ROSDS library.
Just so you know, I spawned it without any other modification: I did with the default env provided from Live Class #81.
Below is the error message:
process[spawn_turtlebot_model-1]: started with pid [1471]
process[mobile_base_nodelet_manager-2]: started with pid [1472]
Traceback (most recent call last):

I’m not familiar with ROSDS now…
If anyone who’ve experienced this kind of issue, would you please give me a piece of helpful advice?
Thanks in advance.
