Converting SSD to frozen graph in tensorflow. Which output node names must be used?

Question

I trained SSD using TensorFlow Object Detection API as described here. It produces a ckpt, meta and index file. In order to run it on my images I tried to check the demo code. It requires that the model be converted to frozen graph. I tried to convert my model to a frozen inference graph as described here. In that program I have to provide output node names. I could not figure out the name of the node in the SSD model which must be used here. Please help. I tried 'num_detections:0', 'detection_boxes:0' etc. Only to get error:

AssertionError: num_detections is not in graph

Answer 1

We have a special tool to convert to frozen graphs in the Tensorflow Object Detection API --- just run the export_inference_graph.py binary. Directions for using this tool are here.
