Hi, the training script now expects you to specify where the language model is, so it can build a proper configuration file. Language model training is independent from translation model training and it is typically done with tools like SRILM or IRSTLM.
For instance, when you train a 5-gram language model with SRILM you will end up with some file, and this file needs to specified with the switch --lm factor:order:filename Factor is usually 0 (unless you do something with factored translation models), Order is 5 in this case (a 5-gram model) and filename should include the full path to the language model. Using --last-step 8 is not the best solution, since now the script will not build a configuration file. -phi On Fri, Mar 30, 2012 at 12:45 PM, Taylor Rose < [email protected]> wrote: > hmm well I just added "--last-step 8" and now it seems to be running > alright.
