How to change the grammar file for another language

[armheb]

Hi, I was trying to use your model and train it on another language. I have a dataset of english texts and corresponding codes. how should I change the grammar file for my own language?
Thanks

You'll want to try out tranX: https://github.com/pcyin/tranX

It has better accuracy, is currently supported, and natively supports adding new languages.
