[SOLVED] pb to dlc conversion with snpe fails using a re trained Tensorflow Object Detection model

Tensorflow version: 2.5

Snpe version: 1.51

Using a pre-trained model from the Tensorflow Model Zoo, I am re-training it to detect only one class of object. Exporting the trained model as saved_model format according to TF2. However, running this through snpe-tensorflow-to-dlc cli command gives an error that the model is empty.

Command:

snpe-tensorflow-to-dlc --input_network ./models/mobilenet2/mobi/saved_model --input_dim input_tensor "1,320,320,3" --out_node detection_classes --out_node detection_boxes --out_node detection_scores --out_node num_detections --output_path mobilenet_ssd.dlc  --show_unconsumed_nodes --debug

Error:

2021-07-20 13:01:31,624 - 183 - ERROR - Conversion FAILED!

NOTE: Running the same command on the pre-trained model directly results in the successful conversion of the model.

I am assuming the error is due to the change in the number of classes while re-training the model. What can be done to solve this error? There is minimal information out there regarding this and the Qualcomm Developer forum seems to be completely inactive.
