主题： tree-to-string model tuning parameter error
hello,
I trained tree-to-string model using moses , Should I also add the options
-hierarchical -glue-grammar, or only --source-syntax ,another problem,when
tuning the parametres,an error occurred, like this:
...........
NO BEST TRANSLATION
End. : [34.000] seconds
Peeking at the beginning of nbestlist to get order of scores: run1.best100.out
Line empty in nbestlist 'run1.best100.out' at
tools/moses-scripts/scripts-20100517-1641/training/mert-moses.pl line 906.

I find in the filtered folder ,phrase table is empty ,I also created rules.bin
to decode ,but failed ,too!
Is the parallel corpus too small ? It's only 4000 lines.
best wishes !
