[Kaldi-users] error in making formatting LM using srilm in swbd recipe

[Xingyu Na <asr...@gm...>]

Hi,

I am running the swbd/s5c recipe. In the step of "Compiles G for swbd 
trigram LM", error is printed as:
================================
Using SRILM tools from 
/nobackup/f1/software/kaldi/kaldi-trunk/tools/srilm/bin/i686-m64
Converting 'data/local/lm/sw1.o3g.kn.gz' to FST
*** Error in `ngram': munmap_chunk(): invalid pointer: 
0x00007fcfec569880 ***
Aborted
================================

I looked into the script and try hunting the error, found that it 
happened when running:
change-lm-vocab -vocab kaldi.I4jS/voc -lm kaldi.I4jS/lm.gz -write-lm 
kaldi.I4jS/out_lm -subset -prune-lowprobs -unk -tolower -order 3

If I run this command alone, it complains:
change-lm-vocab: 78: 
/nobackup/f1/software/kaldi/kaldi-trunk/tools/srilm/bin/change-lm-vocab: 
ngram: not found

I checked the LM and it does contain 1, 2, and 3 ngrams in arpa format. 
So what is this error about?
Please help and thank you very much.

Best,
Xingyu
