title: Python Array Reshaping Issue to Array with Shape (None, 192)
body: <p>I have this error and I'm not sure how do I reshape where there's a dimension with <code>None</code>.</p>
  
  <pre><code>Exception: Error when checking : expected input_1 to have shape (None, 192) but got array with shape (192, 1)
  </code></pre>
  
  <p>How do I reshape an array to (None, 192)? </p>
  
  <p>I've the array <code>accuracy</code> with shape <code>(12, 16)</code> and I did <code>accuracy.reshape(-1)</code> that gives <code>(192,)</code>. However this is not <code>(None, 192)</code>.</p>
