title: Importing tflearn is very slow
body: <p>Importing tflearn takes a large amount of time compared to other modules.</p>
  
  <p>On a newly created virtual environment with only tflearn and minimal dependencies installed with <code>pip</code>:</p>
  
  <ul>
  <li><code>import numpy as np</code> takes ~0.18s</li>
  <li><code>import tensorflow as tf</code> takes ~0.90s</li>
  <li><code>import tflearn</code> takes ~3.1s (and asks me to install h5py and scipy).</li>
  </ul>
  
  <p>After installing h5py and scipy as suggested, time consumed by <code>import tflearn</code> goes up to ~3.5s.  How can I reduce importing time?</p>
  
  <p>(All tests above are done by putting the statement in test.py and run <code>time python test.py</code> several times.  The reported time is the "real" time as reported by <code>time</code> builtin of bash.)</p>
