描述

Hi Everyone,

Is there any way of adding more vocabulary to a Field object that already has had its vocab built?

for example if at one point I have run this sort of code:

TEXT = field()
TEXT.build_vocab(dataset_a)

Is it possible to add vocab to TEXT from another dataset without erasing the current vocab built from dataset_a?

Thanks!

研究方向
Investigate the current Field.build vocab implementation to see if it can be modified to allow incremental vocabulary updates. Review comments in the issue for suggested approaches. Consider adding a method like `extend vocab` that merges new words into the existing vocab without clearing the existing ones.
