Hi,
During incremental retraining I specified the following line in moses.ini
PhraseDictionaryBitextSampling name=PT0 output-factor=0 num-features=9
path=/home/sandipan/inc_retrain/MT_sys/EnPl/mtdata_pro/train. L1=en L2=pl
pfwd=g pbwd=g smooth=0 sample=1000 workers=1

this generates the error:
Feature function PT0 specified 9 dense scores or weights. Actually has 0.

which is solved when num-features is changed to '0'
but generates the error below:

Exception: moses/TranslationModel/UG/mmsapt.cpp:381 in virtual void
Moses::Mmsapt::Load() threw util::Exception because
`this->m_feature_names.size() != this->m_numScoreComponents'.
At moses/TranslationModel/UG/mmsapt.cpp:381: number of feature values
provided by Phrase table (7) does not match number specified in Moses
config file (0)!
Changing it to 7 also does not help.

I have tried with
Mmsapt name=PT0 output-factor=0 num-features=0
base=/home/sandipan/inc_retrain/MT_sys/EnPl/mtdata_pro/train. L1=en L2=pl

but does not work.
What I need to do at this stage of retraining using moses?

Thanks and regards,
sandipan
