title: `from theano import * ` failed - no attribute `find-graphviz`
body: <p>I am attempting to import theano. As I tried</p>
  
  <pre><code>from theano import * 
  </code></pre>
  
  <p>it showed </p>
  
  <pre><code>AttributeError: 'module' object has no attribute 'find_graphviz'. 
  </code></pre>
  
  <p>I read this post <a href="https://stackoverflow.com/questions/38446771/importing-theano-attributeerror-module-object-has-no-attribute-find-graphvi">Importing theano: AttributeError: &#39;module&#39; object has no attribute &#39;find_graphviz&#39;</a> and <code>$git clone https://github.com/erocarrera/pydot.git</code>, <code>$pip install pydot</code>.</p>
  
  <p>However, this does not work for me. As I returned to ipython and <code>from theano import *</code> I still got the same error. I also unsuccessfully tried <code>sudo apt-get install -y graphviz libgraphviz-dev</code>. Would anyone have a different solution? Thank you!!</p>
