title: .tflite vs .lite file formats. Which to use? Why?
body: <ol>
  <li>What is the difference between .tflite and .lite file?</li>
  <li>Which file format is recommended, and why? Is any of them is deprecated?</li>
  <li>What is the correct way to train image categorisation model to .tflite model?</li>
  </ol>
  
  <p>I have downloaded TensorFlow's sample project and it works on .tflite format. But my image categorisation model is of .lite format. I changed my model's format to .tflite and my project run successfully without crashing, but it does not gave any result/output. Not sure if its the model, or the code that is causing the issue.</p>
  
  <pre><code>private let modelDataHandler: ModelDataHandler? = ModelDataHandler(modelFileName: "graph", labelsFileName: "labels", labelsFileExtension: "txt")
  </code></pre>
