title: How do I use Tensorflow's Estimator API to do distributed training?
body: <p>The <a href="https://www.tensorflow.org/programmers_guide/estimators" rel="nofollow noreferrer">documentation</a> says:</p>
  
  <blockquote>
    <p>You can run Estimators-based models on a local host or on a
    distributed multi-server environment without changing your model.
    Furthermore, you can run Estimators-based models on CPUs, GPUs, or
    TPUs without recoding your model.</p>
  </blockquote>
  
  <p>Is there documentation to explain how to run an Estimator in a distributed multi-server environment?</p>
