I have previously looked at this but it is a different error than the warning that I am working with. I am able to successfully export a SavedModel from a trained checkpoint using ‘exporter_main_v2.py’ but the trouble I’m facing is working with the exported saved model after that. I need to convert the exported saved model to another format using a command that calls the function 'meta_optimizer.cc, which then returns an empty graph with 0 nodes and 0 edges after ‘optimizing’ it. I have posted a question about that specifically here 'function_optimizer.py' returns empty graph 13
