Runtime Environment

This system has been tested in the following environment.

• 64bit-Ubuntu
• Python 2.7
• > Pytorch 0.4

Data Preparation

Name the file names of the datasets according to the variables in the wargs.py file

Training Dataset

• Source side: dir_data + train_prefix + '.' + train_src_suffix
• Target side: dir_data + train_prefix + '.' + train_trg_suffix

Validation Set

• Source side: val_tst_dir + val_prefix + '.' + val_src_suffix
• Target side:
  • One reference
    val_tst_dir + val_prefix + '.' + val_ref_suffix
  • multiple references
    val_tst_dir + val_prefix + '.' + val_ref_suffix + '0'
val_tst_dir + val_prefix + '.' + val_ref_suffix + '1'
......

Test Dataset

• Source side: val_tst_dir + test_prefix + '.' + val_src_suffix
• Target side:
  for test_prefix in tests_prefix
  • One reference
    val_tst_dir + test_prefix + '.' + val_ref_suffix
  • multiple references
    val_tst_dir + test_prefix + '.' + val_ref_suffix + '0'
val_tst_dir + test_prefix + '.' + val_ref_suffix + '1'
......

Training

Before training, parameters about training in the file wargs.py should be configured
then, run sh train.sh

Inference

Assume that the trained model is named best.model.pt
Before decoding, parameters about inference in the file wargs.py should be configured

• translate one sentence
  run python bin/wtrans.py -m best.model.pt
• translate one file
  • put the test file to be translated into the path val_tst_dir + '/'
  • run sh trans.sh filename

evaluate alignment

score-alignments.py -d path/900 -s zh -t en -g wa -i force_decoding_alignment
