Error while computing probabilities of gold data using a model without attention

angelikilazaridou commented 8 years ago

Hi there,

I seem to be having a problem when trying to compute the probabilities of the gold data under some model trained without attention. While I'm able to decode and obtain predictions, when scoring the gold data (i.e., by using the option parameter -targ_file data/targ-val.txt on the demo data), the model produces the following error.

As a note, everything works smoothly if I train with attention.

command

th beam.lua -model demo-model_epoch1.00_3095.37.t7  -src_file data/src-val.txt -targ_file data/targ-val.txt  -output_file pred.txt -src_dict data/demo.src.dict -targ_dict data/demo.targ.dict  -gpuid 1

output

loading demo-model_epoch1.00_3095.37.t7...  
done!
