Hello @Scotvers @eyaleyal ,

That looks like a sourcing issue. Could you please try resetting your Shell (click on the red cross on the top-right corner of the Shell) and try running the following commands:

source /opt/ros/foxy/setup.bash
source ~/ros2_ws/install/setup.bash
ros2 run simple_grasping basic_grasping_perception_node --ros-args -p debug_topics:=true
