Custom Vocab File.

[latuanvinh1998]

Hello @kuanghuei.
I read your paper and the "Data pre-processing" section carefully, but I could not find how to produce my vocab.json file for my custom dataset.
Could it be coco_precomp_vocab.json is enough for downstream on another dataset or if I need to create a new vocab file for my custom dataset?
Thank you for your excellent work.
