    Try this to see if your script is outputting any errors:

<?php
    exec('/path/to/python your-script.py 2>&1',$ret);
    print_r($ret);
?>

    If that works, you may just need to adjust your timeout and set
ignore_user_abort(1) to allow the Python script to keep running.  If
all else fails, and you're aware of the side-effects, go fork()
yourself.  ;-P
