Hi Moses-Support

I firstly build the lm as below:

(base) aaronhan@grove2:~/Moses$ head -20
/home/aaronhan/Moses/lm/wmt18_5maaZhEn.arpa.en

\data\

ngram 1=553697

ngram 2=8790963

ngram 3=28838697

-4.663717 talented -0.3983

-5.2061567 topless -0.27003714

Then, I binary it as bellow:

/home/aaronhan/Moses/mosesdecoder/bin/build_binary
/home/aaronhan/Moses/lm/wmt18_5maaZhEn.arpa.en
/home/aaronhan/Moses/lm/wmt18_5maaZhEn.blm.en

(base) aaronhan@grove2:~/Moses$ ls -lh

-rw-r--r-- 1 aaronhan users 715M Jul 29 18:38
/home/aaronhan/Moses/lm/wmt18_5maaZhEn.blm.en

when I test it, it looks working out:

(tensorflow) aaronhan@grove2:~/Moses/working$ echo "is this an English
sentence ?" \

However, when I run the overall Moses training, it produced error as below:
*Wrong format of --lm. Expected: --lm factor:order:filename*

(tensorflow) aaronhan@grove2:~/Moses/working$ nohup nice

nohup: ignoring input

Using single-thread GIZA

using gzip

ERROR: Wrong format of --lm. Expected: --lm factor:order:filename at

Can you let me know how to solve this, please?

Kind regards,
Aaron
