[Moses-support] Error building LM using IRSTLM (compile-lm)

[Zheng Yuan]

Hi,

When I tried to build a LM using IRSTLM. I followed the steps. But when I input 
“~/working/irstlm/bin/compile-lm train.lm.t.gz train.arpa.t”

I got the following error message:
inpfile: train.lm.t.gz
outfile: train.arpa.t
loading up to the LM level 1000 (if any)
dub: 10000000
Language Model Type of train.lm.t.gz is 1
Language Model Type is 1
iARPA
loadtxt_ram()
1-grams: reading 3479 entries
compile-lm: util.cpp:289: int parseline(std::istream&, int, ngram&, float&, 
float&): Assertion `howmany == (Order+ 1) || howmany == (Order + 2)' failed.
Aborted (core dumped)

Is there anyone can help me with that? Thank you in advance!

Regards,
Zheng
