title: Convert a numpy.ndarray to string(or bytes) and convert it back to numpy.ndarray
body: <p>I'm having a little trouble here,</p>
  
  <p>I'm trying to convert a numpy.ndarray to string, I've already done that like this:</p>
  
  <pre><code>randomArray.tostring()
  </code></pre>
  
  <p>It works, but I'm wondering if I can transform it back to a numpy.ndarray.</p>
  
  <p>What's the best way to do this?</p>
  
  <p>I'm using numpy 1.8.1</p>
  
  <p><em>Context:
  The objective is to send the numpy.ndarray as a message in rabbitmq (pika library)</em></p>
