title: How to save Tensorflow encoder decoder model?
body: <p>I followed <a href="https://colab.research.google.com/github/tensorflow/tensorflow/blob/master/tensorflow/contrib/eager/python/examples/nmt_with_attention/nmt_with_attention.ipynb#" rel="nofollow noreferrer">this tutorial</a> about building an encoder-decoder language translation model and built one for my native language.</p>
  
  <p>Now I want to save it, deploy on cloud ML engine and make predictions with HTTP request. </p>
  
  <p>I couldn't find a clear example on how to save this model, </p>
  
  <p>I am new to ML and found <a href="https://www.tensorflow.org/guide/saved_model" rel="nofollow noreferrer">TF save guide</a> v confusing..</p>
  
  <p>Is there a way to save this model using something like
