title: TensorFlow: freeze graph tensorflow for poets
body: <p>I'm new to tensorflow and I'm following the tensorflow for poets 2 tutorial and clone their repo: <a href="https://github.com/googlecodelabs/tensorflow-for-poets-2" rel="nofollow noreferrer">https://github.com/googlecodelabs/tensorflow-for-poets-2</a></p>
  
  <p>In the tutorial I learned how to run the scripts for retraining, evaluation, optimize for inference, quantize_graph in cmd. <strong>Now I'm curious about "Freezing".</strong></p>
  
  <p>In this stackoverflow question I learned on how to run the freeze_graph in cmd:
  <a href="https://stackoverflow.com/questions/42439233/how-to-use-freeze-graph-py-tool-in-tensorflow-v1">How to use freeze_graph.py tool in TensorFlow v1</a></p>
  
  <p>The problem is this so called "checkpoint" which I didn't have when following the tutorial tensorflow for poets 2. <strong>My question is how do I obtain this checkpoint file? Since I only have the .pb and labels after training my data</strong></p>
  
  <p>Note: I'm aware that there is no freeze_graph.py in the repo above thats why I copied it from <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/python/tools" rel="nofollow noreferrer">https://github.com/tensorflow/tensorflow/tree/master/tensorflow/python/tools</a> in hope that I can use it.</p>
  
  <p>Thanks</p>
