title: "Could not find a version that satisfies the requirement opencv-python"
body: <p>I am struggling with Jetson TX2 board (aarch64).</p>
  
  <p>I need to install python wrapper for OpenCV.</p>
  
  <p>I can do:</p>
  
  <pre><code>$ sudo apt-get install python-opencv
  </code></pre>
  
  <p>But I cannot do:</p>
  
  <pre><code>$ sudo pip install opencv-python
  </code></pre>
  
  <p>Is this because there is no proper wheel file in <a href="http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv" rel="noreferrer">http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv</a>?</p>
  
  <p>Is there a way to install opencv-python through pip?</p>
