More context: I am trying to convert a MobilenetV2 SSD re-trained SavedModel into another framework format. I have successfully re-trained the model and exported the checkpoint to a SavedModel using exporter_main_v2.py. However, when I try to run the conversion script, it calls the 'meta_optimizer.cc file, which eventually results in an empty graph that cannot be converted.
The following is the output that I get:
