  <pre><code>pip uninstall -y mxnet &amp;&amp; pip install mxnet-cu90==1.1.0
  </code></pre>
  
  <blockquote>
    <p>Adjust 'cu90' depending on your CUDA version ('cu75' and 'cu80' are
    also available).
        You can also disable GPU usage altogether by invoking turicreate.config.set_num_gpus(0). 
        An exception has occurred, use %tb to see the full traceback.</p>
