When I am trying to classify

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

I am getting below error

float division by zero

Please post the full error details, this will tell me which line of code caused the error.

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
