Trouble with python nodes in launchfile
Hi everyone!
I am trying to start some additional nodes together with the minimal.launch file, so I made the following additions for my nodes.
I sourced the devel/setup.bash file so the package can be found and made sure the py files are executable using chmod +x. Nonetheless, when I try to run the launch file, I get the following errors. It does seem quite generic to me, has someone experienced this before and has an idea?
Thank you!
The lines I added:
<node name="webcam_pub" pkg="webcam_pub" type="webcam_pub.py" />
<node name="pos_pub" pkg="stop_snap" type="pos_pub.py" />
<node name="go_to_goal_v5" pkg="stop_snap" type="go_to_goal_v5.py" />
What I get as output in the console (log files are empty).
process[webcam_pub-14]: started with pid [6036]
