What version of Ubuntu are you using? 32 or 64 bit? please paste the output of lsb_release -a and uname -a, and also the exact commands you used to compile the wrappers. Also please provide the output of dpkg -s ros-indigo-v4r to see what version you are basing this on.

I compiled the wrappers via catkin_make in my workspace. I also installed the latest ros-indigo-v4r-ros-wrappers and ros-indigo-v4r from synaptic package manager, but when i run roslaunch '/opt/ros/indigo/share/singleview_object_recognizer/launch/recognition_service.launch' ERROR: cannot launch node of type [singleview_object_recognizer/recognition_service]: can't locate node [recognition_service] in package [singleview_object_recognizer]

[marc-hanheide]

Right... I cannot see what's going wrong here, to be honest. When you simply install ros-indigo-v4r-ros-wrappers it should contain recognition_service. I tested on my machine and it seems to work... I tried roslaunch singleview_object_recognizer recognition_service.launch models_dir:=/tmp training_dir:=/tmp

I have only the Ubuntu packages installed on that machine. Maybe @ToMadoRe, @mzillich or @taketwo have ideas why it's not working.

Just to be sure, can you update your system with apt-get update and apt-get upgrade once more, please. And make sure you have no own ROS workspace configured, so that indeed only the installed packages are being used.

[Yanzqing]

I solve the problem cannot launch node of type [singleview_object_recognizer/recognition_service]: can't locate node [recognition_service] in package [singleview_object_recognizer] Thank you for your help!

[MRLoghmani]

@Yanzqing could you please report how you solved the initial problem?
