title: AttributeError: 'module' object has no attribute 'subscribe' Python
body: <p>I'm Using <code>Kubuntu 13.10 64 bit</code> and <code>Python 2.7.5+</code> and <code>wxPython 2.8.12.1</code>. I'm trying to use the <code>wx.lib.pubsub</code> module to update <code>wx.Gauge</code> from different class (thread class). I have in my code such imports:</p>
  
  <pre><code>try:
      from pubsub import pub
  except ImportError:
      from wx.lib.pubsub import pub
  </code></pre>
  
  <p>but  when I start my application, I'm getting the error: </p>
  
  <pre><code>    pub.subscribe(self.updateProgress, "update")
  AttributeError: 'module' object has no attribute 'subscribe'
  </code></pre>
  
  <p>What's wrong and how to fix it?</p>
