If I want to calculate the BLEU score for the model, how should I do?

[YuDeng]

Hello! I really appreciate for your great code of NIC model. I've revised your code and have done an training process based on your code. I want to know how I can test BLEU score of the model to see how well it works compare to the state-of-art results? Is there any resources for computing the score or other scores like METER or perplexity?
Thanks a lot :)

Hello @YuDeng,

With the code, the training process, it give result as many models file. Which one you use for your model?
