title: Running two tensorflow graphs at a time
body: <p>I have trained 2 models for slightly different OCR tasks and I would like to run them both at the same time in a production system. </p>
  
  <p>I have a class that starts a session and loads the saved model. The problem I am having is that the 2 models have variables saved with the same name so they are conflicting when I try to load them in.</p>
  
  <p>Is there a way to run them each in their own session or on their own graph?</p>
