title: TFLearn import issue - no module core_rnn
body: <p>I am testing out the TFLearn library for using TensorFlow but can't import it due to some config issue. I installed it as required in TFLearn tutorial though. Thankful for any help.</p>
  
  <pre><code>&gt;&gt;&gt; import tflearn as tf
  &gt;    import tflearn
  
    File "//anaconda/lib/python2.7/site-packages/tflearn/__init__.py", line 4, in &lt;module&gt;
      from . import config
  
  ImportError: cannot import name config
  </code></pre>
