Revision history [back]

Did you install object_recognition from source or as a deb package? I just tested with...

sudo apt-get install ros-electric-object-recognition

... and it worked (at least I got past the point where you got that error). Make sure you don't have another copy of object_recognition checked out somewhere on your ROS_PACKAGE_PATH.
