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

Someone please answer these completely, THANKS
Hi all
I have a few question about tuning step of moses SMT.
1. Why we need tuning of the system ? as We can decode without it then why do we need it>?
2. What is reason behind getting optimized weights and where these weights are being used while decoding???
3. Why corpus is needed for tuning and why we cant use training datatset or testset for tunning of the system???


THANK YOU
