Hi, what project are you completing? Are you following the steps provided in the rosject’s notebook?

That’s a strange error, so maybe deleting this rosject and re-forking a new copy might fix it for you.

I want to complete Wall Following robot final project.
This is my Rosject folder, if you have access I request to please check.
I have created a new package, this is the only way to learn, I was surprised if I pick a new project , it does not support basic features. I already troubleshoot a lot, now I need help, If I use course project folder , there it is work, but I want to create a new project and then submit project for getting certification, this will help me for my future projects also, please help or share instructions how to configure it

I think there is a misunderstanding here. That is not a course project rosject, that is a separate rosject. In order for you to be able to do the project you need to get the link from the course you are taking in order to fork a copy of the appropriate rosject. You didn’t mention which course you were taking, but I asume it’s ros basics.

Here is the link for both Python and C++ courses:
