Hi @Abod147
Welcome to the Stereolabs community.
Did you install also the zed-ros-examples repository?
yes, i did install it.
In this case, you must be sure that you followed the install instructions to set the environment variables correctly.
Can u provide me with the link for the correct steps of the object detection tutorial?
So, after i run the zed 2i camera how can i enable the object detection to make it (true). And after i make it true what should i do to visualize the results of the object detection?
Thank you for your fast replies always 
You must modify common.yaml to directly enable the object detection when the node starts, or call the enable_object_detection service
hiii @Myzhar, so i enabled the object detection to true and after that i launched the ros pack of the camera, and then while it was loading it loaded a optimizing object accurate. however it stopped at 90.1% with 34 sec remain. do u have any clue what should i do ?
I recommend you manually optimize the AI modules before starting the ROS node:
