Dear all:
I am a new hand at moses and machine translation. I was trying to completing a task of translation between two unknown languages.I had completed the word segmentation and clean the corpus with the command: clean-corpus-n.perl train-split.txt right left train-split.clean 1 120
(PS:the two pararrel corpus with extension left and right)
Then I ran the train-model perl as follows:
train-model.perl -root-dir train --cores 8 --corpus /home/yuff/mosesdecoder/projectdata/accessor_variety/train-split.clean --f right --e left --alignment grow-diag-final-and --first-step 2 --reordering msd-bidirectional-fe --lm 0:3:/home/yuff/mosesdecoder/projectdata/accessor_variety/train-split.blm.left --mgiza -mgiza-cpus 2 --parallel --external-bin-dir /home/yuff/mosesdecoder/word_align_tools/


There were a lot of warnings beginning with "Use of Uninitialized Value in " coming out, without ending the executing of perl. However, after about 20 minutes, I got the error as follows:


"Executing: /home/yuff/mosesdecoder/scripts/../bin/lexical-reordering-score /home/yuff/mosesdecoder/projectdata/accessor_variety/translating_working/train/model/extract.o.sorted.gz 0.5 /home/yuff/mosesdecoder/projectdata/accessor_variety/translating_working/train/model/reordering-table. --model "wbe msd wbe-msd-bidirectional-fe"

ERROR: Lexical reordering scoring failed at /home/yuff/mosesdecoder/scripts/training/train-model.perl line 1924."


The files under the directory "/train" are extremely small or even empty. I searched for the problem and found some others asking about that in 2012: He got the reply like this



However, '[',']' are both characters in these two languages, and uppercase and downcase letters are recognized as different ones. I'm not sure if the first step of training would downcase the letters, so I started with the second step.
I will appreciate it so much if some ones can give some suggestions. Thanks!
