title: How to convert numpy arrays to standard TensorFlow format?
body: <p>I have two numpy arrays:</p>
  
  <ul>
  <li>One that contains captcha images</li>
  <li>Another that contains the corresponding labels (in one-hot vector format)</li>
  </ul>
  
  <p><strong>I want to load these into TensorFlow so I can classify them using a neural network. How can this be done?</strong></p>
  
  <p>What shape do the numpy arrays need to have? </p>
  
  <p>Additional Info - My images are 60 (height) by 160 (width) pixels each and each of them have 5 alphanumeric characters. Here is a sample image:</p>
  
  <p><img src="https://i.stack.imgur.com/lSZYb.png" alt="sample image."></p>
  
  <p>Each label is a 5 by 62 array. </p>
