title: Bad Marshal error -- runsnake
body: <p>I ran cProfile on a python 3 script, worked nicely, then tried to visualize it using runsnake. Howvever, I got an empty screen and the error 'bad marshal data'.</p>
  
  <p>I removed .pyc file but that did not work either.</p>
  
  <p>The code I used to install runsnake was:</p>
  
  <pre><code>    sudo apt-get install python-profiler python-wxgtk2.8 python-setuptoolD
      sudo easy-install installSquareMap RunSnakeRun
  </code></pre>
  
  <p>I am using UBUNTU.</p>
  
  <p>Many thanks.</p>
  
  <p>note: I should add I installed everything while py3k was activated</p>
