Graph_optimization with Grappler a SavedModel

TensorFlow General Discussion

Hello, I am trying to optimize a SavedModel following this guide: Google Colab.
I need to apply the “Constant folding optimizer” and I think I should use the tensorflow.python.grappler.tf_optimizer.OptimizeGraph() function.
From the function definition I get that I need the MetaGraph but I don’t know how to obtain this and I don’t know if it is the correct approach.

Please let me know if it is the right procedure.

Thank you
