 ## Code Breakdown
 Ain't that something! If you followed the breakdown in object detection, you'll find that the only change if you are looking to detect faces instead of objects is in using a different deep learning model that does just that. For this, we will explore how to use the OpenVINO toolkit. Let's head to the detect_faces.py node to begin.

 The detecion_node.py script then takes over as we saw with the object detection tutorial to publish the detections on pertinent topics. 
 
-Now go ahead and experiment with a few more pretrained models using PyTorch or OpenVINO on Stretch. If you are feeling extra motivated, try creating your own neural networks and training them. Stretch is ready to deploy them.
