title: How can I sort each row of the 2d numpy-array by another 2d index-array?
body: <p>For example, I have:</p>
  <pre><code>arr = np.array[[10 30 20],
                 [30 20 10]]
  
  indices = np.array[[2 1 0],
                     [2 1 0]]
  </code></pre>
  <p>I want:</p>
  <pre><code>[[20 30 10],
   [10 20 30]]
  </code></pre>
  <p>Thank you very much!!</p>
