Hi all,
I am trying to use the ES-EN language pack from our "Language Packs" page
with Joshua 6.1, but when I get to load the two language models I get an IO
execption.
The config looks like:
feature-function = LanguageModel -lm_type berkeleylm -lm_order 4 -lm_file
model/lm.berkeleylm
feature-function = Distortion
feature-function = LanguageModel -lm_type berkeleylm -lm_order 4 -lm_file
model/en.giga.twopercent.4.lm.berkeleylm
feature-function = PhrasePenalty
and I get the following:
java.lang.RuntimeException: java.lang.RuntimeException: Unable to
instantiate feature function 'LanguageModel -lm_type berkeleylm -lm_order 4
-lm_file model/lm.berkeleylm'!
...
Caused by: java.lang.RuntimeException: Unable to instantiate feature
function 'LanguageModel -lm_type berkeleylm -lm_order 4 -lm_file
model/lm.berkeleylm'!

Any hints on what I could be doing wrong ? Encoding ?
Did anyone else experience such issue ?
BTW I am running this from within a Java application, Decoder is
initialized as follows:
JoshuaConfiguration configuration = new JoshuaConfiguration();
configuration.readConfigFile(pathToJoshuaConfig);
configuration.use_structured_output = true;
Decoder decoder = new Decoder(configuration, pathToJoshuaConfig);
Regards,
Tommaso
