Hi @TysonYu, a suggestion to change the init PR message of Closes #{ISSUE_NUMBER} so that it will be linked to the dataloader issue for coming PRs (I've done it on this one, tho).

Okay, will do it for later ones.

rather than having to write on _split_generators and re-read again in _generate_examples, why we don't pass the all_data list in _split_generators gen_kwargs and use it directly on generate_examples? I think passing such is possible (see this SEACrowd Implementation)

Hey, I do by this way because it seems to be logically correct and clear. I agree your mentioned approach is another implementation and still my current approach should be fine. I think some other dataloaders also did in this way, such as indosum.
