Issues regarding nodelet_manager and map_server
Hello all, I am facing a startup issue with the nodelet_manager and also with the map_server. I am trying to setup this on a Nvidia Jetson Nano board, though the same setup is working on a Raspberry Pi 3B+ board. For Jetson, it's diving into certain issues, I resolved many but unable to resolve these ones. I am attaching the relevant output from the terminal which I get when I run the project.

do you have the
yocs_velocity_smootherpackage installed?What is the output of
rospack find yocs_velocity_smoother?@gvdhoorn Thanks for the suggestion, I had already solved the problem by installing the concerned package, I've now edited the scenario of the problem with the current problems am facing.
Please don't do this.
This is not a forum, but a Q&A site, which works best with a 1-to-1 ratio of problems-to-answers.
Revert your edit, post how you solved your initial problem as an answer, accept your own answer.
Then post a new question with your current problem -- after having made sure you're not posting a duplicate (use Google to search, append
site:answers.ros.orgto your query).Oh, and:
this sentence does not give any information. We don't know what you've tried, so we cannot avoid giving you the same advice/help.
Please always describe what you've already read and done, and why that didn't (seem to) help.
@gvdhoorn Thanks for the suggestions regarding the usage of the site. I've done the relevant changes and asked for another question regarding the problems currently. Am new to this site so mistakes, apologies for the same, I'll make sure to follow the ethics in the future.
No need to apologise.
Thanks for reverting.
