title: How to downgrade tensorflow version in colab?
body: <p>I am using <code>pip3 install tensorflow==1.8.0</code>, but it doesn't have GPU support.</p>
  
  <p>So I am using <code>pip3 install tensorflow-gpu==1.8.0</code>, but it still raises an exception</p>

  <p>Should I use <code>colab</code> to install <code>tensorflow</code> from source?</p>
  
  <p>After <code>pip3 list</code>:</p>
  
  <pre><code>tensorboard              1.10.0   
  tensorflow               1.10.0   
  tensorflow-hub           0.1.1   
  </code></pre>
