  <p>And I keep getting this error when trying to subtract the first array from the other: </p>
  
  <pre><code>ValueError: Shape of passed values is (97, 97), indices imply (1, 97)
  </code></pre>
  
  <p>What can I do to match the shape of the arrays together so I can subtract them? 
  I am newish to numpy and am stuck on this problem </p>
