title: How to get a Queue object from a TensorFlow graph?
body: <p>In TensorFlow I have a graph that has in it a string_input_producer that is used in it's input pipeline.</p>
  
  <p>I am loading the graph from a checkpoint file, so I do not have access to the original object when it was created. Nonetheless, I need to run the enqueue method of this object.</p>
  
  <p>I have tried getting the FIFOQueue object using get_operation_by_name and get_tensor_by_name, which obviously did not work because the queue is neither an operation nor a tensor. Is there any function like the mentioned that would do what I want? (fake e.g. get_queue_by_name) How can I solve my problem otherwise?</p>
