How to get the BLEU value of the test corpus

[yapingzhao]

Hi,
python -m nmt.nmt
--out_dir=/tmp/nmt_model
--inference_input_file=/tmp/my_infer_file.vi
--inference_output_file=/tmp/nmt_model/output_infer
--vocab_prefix=/tmp/vocab
Run the above command to get the translated translation, but there is no BLEU value, how to get the BLEU value, what is the command?

Looking forward to your advice or answers.
Best regards,
Thank you very much!

Hello, in my project I did it in a following way:

1. Create script named nmt/eval_bleu.py
   from .utils import evaluation_utils
import sys
ref = sys.argv[1]
hyp = sys.argv[2]
print(evaluation_utils.evaluate(ref, hyp, 'bleu'))

2. Run it
   python3 -m nmt.eval_bleu <reference file> <translation file>
