   Hi,
   these are the two commands I ran for training:

   python bayes.py learn spam ../outspam.csv 500 //Processed 500 documents of type 'spam'
   python bayes.py learn fine ../outfine.csv 500 //Processed 500 documents of type 'fine'

   And after this i tried this below classify command and get the 'float division by zero' error

   python bayes.py classify ../testfine.csv spam fine

   float division by zero

   Thus I am unable to tell you exactly which line is causing this issue.

   Please replace the statement 'print ex' in bayes.py with the word 'raise' - that should provide more information about the error

   This is the traceback I got
