body: <p>Scenario: I have exported a TF model and I have the .pb file. The model is a simple classifier which has been trained on images. THe model takes an image as an input and provides whether the image belongs to a certain category with a probability score. </p>

  graph = load_graph('model.pb')</p>
  
  <p>But unable to figure out a way to send an image as input and retrieve results. What attributes should I used to send input and receive results ?</p>
