title: What are the proper file formats for Freezy graph?
body: <p>I am using Tensorflow and Inception v3 CNN. 
  I want to save the trained network using the <a href="https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/tools/freeze_graph.py" rel="nofollow">freeze_graph.py</a></p>
  
  <p>What I have done till now is saving the model in input_graph.pb during training, by using tf.write_graph, and my thoughts are that this should be the “input graph” in the FLAGS.</p>
  
  <ol>
  <li>When it comes to the remaining fields, such as input saver, output nodes and initializer nodes, I`m not sure how to create the proper file formats?</li>
  <li>Another question is how to use the created .meta file from the training?</li>
  </ol>
  
  <p>I would really appreciate if you could take some time to help me.</p>
