  - Setting the input_array, output_array and input_shape arguments are a bit trickier. The easiest way to find these values is to explore the graph in tensorboard . The user should reuse the arguments that were used for specifying the output nodes for inference in the `freeze_graph`step.
  Note, it is also possible to use the Tensorflow Optimizing Converter through protos either from Python or from the command line see the
