[Kaldi-developers] Error during compute-cmvn-stats

[Lee B. <lb...@nc...>]

I am a student trying to come up to speed with both speech recognition
and HMM's and the use of Kaldi.

I was trying to run thru the kaldi tutorial using the LDC switchboard data.

When running
steps/compute_cmvn_stats.sh data/train exp/make_mfcc/train
/mnt/kaldi/egs/swbd_experiment/s5/mfcc_dir
the step
compute-cmvn-stats --spk2utt=ark:data/train/spk2utt
scp:data/train/feats.scp
ark,scp:/mnt/kaldi/egs/swbd_experiment/s5/mfcc_dir/cmvn_train.ark,/mnt/kaldi/egs/swbd_experiment/s5/mfcc_dir/cmvn_train.scp

fails with the following message
ERROR (compute-cmvn-stats:SplitFilename():kaldi-io.cc:504) Cannot get
offset from filename
/mnt/kaldi/egs/swbd_experiment/s5/mfcc_dir/raw_mfcc_train.1.ark:4295001228
(possibly you compiled in 32-bit and have a >32-bit byte offset into a
file; you'll have to compile 64-bit.

In digging thru the install scripts, I couldnt see any references to
compiling with 64-bit.

I am running under cygwin.
So
1) is there an FAQ that would cover these sorts of issues
2) could I get some guidance on how to get around this issue
