Hello,
I have passed more than 90 % in the open_ai ros course and wanted to set up the environment on my local machine. It have been a real challenge for several days. I would really need someone who could help me in the setup. For example currently when I run roslaunch my_turtlebot2_training start_training.launch I have following error. It would be nice if somebody cloud help me in the setup process.

I dont understand what this directory is for. I have created it and have run catkin_make but nothing changes.
Best regards,
