title: GCP DL Image: Base m36 (with CUDA 10.0). How to enable GPU in PyTorch?
body: <p>I am trying to run DL PyTorch jobs on a GCP box. Steps I take:</p>
  
  <ul>
  <li>Create a VM with m36 deep learning image and K80 attached. There is a question re CUDA 10 driver installation at first login, I choose 'y' and the driver gets set up.</li>
  <li>install pyenv</li>
  <li><code>pyenv install 3.7.5</code></li>
  <li><code>pyenv virtualenv 3.7.5 myenv</code></li>
  <li><code>pyenv activate myenv</code></li>
  <li><code>pip install fastai</code></li>
  <li>Start python console and run:</li>
  </ul>
  
  <p>Code:</p>
  
  <pre><code>import torch
  torch.cuda.is_available()
  </code></pre>
  
  <p>It returns <code>False</code>. What am I supposed to do to enable GPU in PyTorch?</p>
