Re: [Kaldi-users] reproducing numbers in wsj/s5

OK, I have an idea what might have happened.  It's possible that because
you are using such a small number of parallel jobs (2), there is a problem
due to numerical roundoff.  This should not be the case because we
accumulate in double, but to see whether this is a factor, could you please
run the training with more jobs?  E.g. 4 or 8? See if the likelihoods
change.  Also, show me the full log from the last update, both before and
after you make the change.
