title: How to restore session in tensorflow?
body: <p>I want to use my neural network without training the net again. 
  I read about </p>
  
  <pre><code>save_path = saver.save(sess, "model.ckpt")
  print("Model saved in file: %s" % save_path)
  </code></pre>
  
  <p>and now I have 3 files in the folder: <code>checkpoint</code>, <code>model.ckpt</code>, and <code>model.ckpt.meta</code></p>
  
  <p>I want, in another class in python to restore the data, get the weights of my neural network and make a single prediction.</p>
  
  <p>How can I do this?</p>
