title: Tensorflow importing crashes Python without any error on Windows
body: <p>Yesterday I was trying to solve matplotlib problems on Windows, which included solving <code>from matplotlib import ft2font</code> error. I have added <code>HDF5_DISABLE_VERSION_CHECK=2</code> for that. But today I found, that tensorflow doesn't work anymore:</p>
  
  <pre><code>&gt; python                                                                                              
  Python 3.5.5 |Anaconda, Inc.| (default, Apr  7 2018, 04:52:34) [MSC v.1900 64 bit (AMD64)] on win32   
  Type "help", "copyright", "credits" or "license" for more information.                                
  &gt;&gt;&gt; import tensorflow as tf                                                                           
  
  &gt;
  </code></pre>
  
  <p>It thinks 30 seconds, then exits Python without any error.</p>
  
  <p>Where can I see logs or crashdumps or something?                                                                                                     </p>
