Hello,

I am following the Quick Start for cob_people_detection in readme.md. When launching

roslaunch cob_people_detection people_detection.launch

everything launches fine but I have error saying: "[ERROR] : Recognition model not trained." Which should be normal because I haven't done any training so far. So, when running :

rosrun cob_people_detection people_detection_client

I have error: No connection to server 'load_model_server'. It appears that server 'load_model_server' is launched in face_recognizer_node.cpp , BUT ONLY if there is trained data! So there is a loop, I can not train data without that server, and there is no server without trained data??

What am I missing? Should I use some other launch file or some other client to train the data first?

Thanks in advance!

Hi, we solved the problem. Just download the current version of cob_people_perception from github. Unfortunately, an error was introduced in one of the commits some months ago.

Try the combination of the following packages:

https://github.com/ipa320/cob_people_...

and

https://github.com/ipa320/cob_percept...

and build them (with catkin_make) in a new catkin workspace (for sure). Do not forget to install all dependencies for both packages and than execute source setup.bash in devel folder.

I assume you're working with ROS Indigo and (x)ubuntu 14.04 (like me). I had the same problem.

Good luck
