Decoding fails (Can't open file: result/<db_name>.match)

[Felix Hennig]

Hey,
Decoding fails, either at the end of "sphinxtrain run" but also with "sphinxtrain -s decode run"
Console output:

Sphinxtrain path: /informatik2/nats/projects/spokenWikipedia/acoustic_model_db_files/sphinxtrain_dir/lib/sphinxtrain
Sphinxtrain binaries path: /informatik2/nats/projects/spokenWikipedia/acoustic_model_db_files/sphinxtrain_dir/libexec/sphinxtrain
MODULE: DECODE Decoding using models previously trained
Aligning results to find error rate
Can't open file /informatik2/nats/projects/spokenWikipedia/acoustic_model2/result/wiki_de_caps.match

It can't read this file because the result directory does not exist. I don't think this is an error though, because here it says that this folder will be created after decoding. What's the problem then?

Also I'd like to know how I can disable the decoding stage in a normal run.

Cheers,
Felix

You need to check logs in logdir folder. You need to provide logs if you need further help.

The logdir didn't contain a "decode" directory, because the psdecode.pl file never got executed.
There is a qmanager/decode.err file:

Configuration (e.g. etc/sphinx_train.cfg) not defined
Compilation failed in require at /informatik2/nats/projects/spokenWikipedia/acoustic_model2/sphinxtrain_dir/lib/sphinxtrain/scripts/decode/psdecode.pl line 53.
BEGIN failed--compilation aborted at /informatik2/nats/projects/spokenWikipedia/acoustic_model2/sphinxtrain_dir/lib/sphinxtrain/scripts/decode/psdecode.pl line 53.

The configuration file does exist though and is syntactically valid.

And if we execute the psdecode file directly, it works.

[Nickolay V. Shmyrev]

Try to add in psdecode.pl and slave.pl in decode:

use strict;

above

use File::Path;
use File::Copy;
use File::Basename;
use File::Spec::Functions;

like in other scripts.

Hi Nickolay,

use File::Path;
use File::Copy;
use File::Basename;
use File::Spec::Functions;

already in files in decode but still not running psdecode.pl, same error throws:
psdecode.pl
Configuration (e.g. ./etc/sphinx_train.cfg) not defined
Compilation failed in require at ./psdecode.pl line 53.
BEGIN failed--compilation aborted at ./psdecode.pl line 53.

In log file no error there, stuck after scanning files.

[Nickolay V. Shmyrev]

Your decoding crashed with OOM error or with some other error it seems. You can debug this issue running pocketsphinx directly from command line.
