  <p>Searching, I found that the problem might be in this call in the code</p>
  <pre><code>import wx
  </code></pre>
  <p>and I need to put the lines</p>
  <pre><code>import wxversion
  wxversion.select('2.8')
  import wx
  </code></pre>
  <p>But then i've receive de the message</p>
  <pre><code>    wxversion.select('2.8')
    File &quot;/usr/lib/python2.7/dist-packages/wxversion.py&quot;, line 144, in select
      raise AlreadyImportedError(&quot;wxversion.select() must be called before wxPython is imported&quot;)
