Moses Support Digest:Tuning failure with Language model type unknown

[Moses-support] Tuning failure with “Language model type unknown.”

Hello,
I am currently trying to train a Moses system, which goes fine until the tuning step. I get the following error :

Creating lexical reordering…
weights: 0.111111 0.111111 0.111111 0.111111 0.111111 0.111111
binary file loaded, default OFF_T: -1
Created lexical orientation reordering
ERROR:Language model type unknown. Probably not compiled
into library
ERROR:no LM created. We probably don’t have it compiled
Exit code: 1
The decoder died. CONFIG WAS -w 0.000000 -lm 0.111111 -d
0.111111 0.111111 0.111111 0.111111 0.111111 0.111111 0.111111 -tm
0.033333 0.022222 0.033333 0.022222 0.000000

I have checked the archives of the mailing list, and couldn’t find anything to resolve the problem.
The language model line in the run1.moses.ini is the following
# language models: type(srilm/irstlm), factors, order, file
[lmodel-file]
1 0 5 /home/s0678231/disk1/mt-system/lm/europarl.binlm.1

Is anyone able to help with this ?

Thanks in advance,
Ronan

Hi Ronan

This is the problem:

> ERROR:Language model type unknown. Probably not compiled

You need to compile with irstlm in order to use a binarised language model.

See here for instructions:

Hi,
It was resolved by removing the lm-binarizer option in the config file.
Thanks for your answer,

Ronan
