title: How to create dataset in the same format as the FSNS dataset?
body: <p>I'm working on this <a href="https://github.com/tensorflow/models/tree/master/attention_ocr" rel="noreferrer">project</a> based on TensorFlow.</p>
  
  <p>I just want to train an OCR model by attention_ocr based on my own datasets, but I don't know how to store my images and ground truth in the same format as FSNS datasets.</p>
  
  <p>Is there anybody also work on this project or know how to solve this problem?</p>
