Re: [Moses-support] About Syntax Decoding (Chart Decoding)

Hi Liukai,

it looks like an error in the sample config file: SRILM is language model type 0, not 1.  Try changing the lmodel-file line from

    1 0 3 lm/europarl.srilm.gz

to

    0 0 3 lm/europarl.srilm.gz

I had download the newest moses (moses-2010-04-26.tgz) and sample-models.tgz.

And all is correct at the beginning:
I use the SRILM and compiled is good .

I run the demo as the manual said , and the pharse-model side is well:
%../../trunk/moses-cmd/src/moses -f moses.ini -i in 
        .................
Loading lexical distortion models...have 0 models

        ....................
Finished translating
End. : [2.000] seconds
 
But there are something wrong with the syntax-model side (something wrong in reading language model):
 
%echo 'ein haus ist das' | ../../trunk/moses-chart-cmd/src/moses_chart -f moses.ini -T

ERROR:no LM created. We probably don't have it compiled
 
I confirm that the file "europarl.srilm.gz" is just there .
And How to manage this problem ?
