title: How to load Google's TFLite model for smartreply into the python interpreter?
body: <p>I am trying to load the <code>smartreply.tflite</code> model into the python interpreter so I can use that to generate replies based on a question. The model uses 3 custom operations(<code>predict</code>, <code>normalize</code> and <code>extract_features</code>).</p>
  
  <p>I am successfully able to load the three operations into the interpreter, however, when I try to load the model into the interpreter, it gives me an error telling me that the operation <code>Normalize</code> wasn't found. </p>
  
  <p>I expect to get no errors when I load the tflite model.</p>
  
  <p>I suspect that when I try to load the model, it only looks for the needed operations in a built-in directory.</p>
