Adding vocab to field object

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!

Cool, thanks for the workflow. I’ll hopefully get around making this easier sometime soon.

Some challenges I am currently facing:

1. Currently there is an extend() method of Vocab which simply goes through itos of an argument and adds them to current vocab. I want to make it more general to accept Counter object as in Vocab.__init__() and also keep in mind original max_size and min_freq arguments. But changing it this way may harm code that is using current entend() method
2. If vocab is built with specials_first=False it becomes unclear how to add new words, since specials will no longer be at the end if itos/stoi
3. I am not sure how to treat a Vocab with existing vectors

Any advice is highly appreciated!
