Have you installed all dependencies, built them, and source your workspace? It looks like ros can not find your nodes.

8 months ago Then I would like to ask, how to solve my problem? Because I'm a novice, I'm new to ros. I hope you can give me some good suggestions, and thank you sincerely for your reply again!

7 months ago Have you tried source ~/catkinw_ws/devel/.bashrc?
There's many great ROS tutorials available online (e.g. http://wiki.ros.org/ROS/Tutorials). I'd suggest familiarizing yourself with ROS and let us know if your errors persist!
Hello! First of all, thank you very much for your wonderful work! I have completed the installation process described in your README.md, and I can also successfully download experimental scenes, ground truth point clouds and other related resources. However, in the following example-configuring Planner, there was a problem when running "roslaunch active_3d_planning_app_reconstruction example.launch", and four errors were generated. The following is the result after I entered this line of command, and I will send you a separate screenshot of the error report. I would be very grateful if you could answer it for me. Looking forward to your reply!
