• Tensorflow >= 1.3
• Maven

please go to model_py/model.py for a toy example

basically what this step does is to convert all trained variables into constant tensors, so that when you later on load the model in Java, you don't need to initialize the variables.
please see model_py/freeze.py

you still need to prepare your inference data and feed in.
