hi @chenxwh thank you for the PR

about the data, since it is publicly accessible after user has accepted the dataset's acknowledgement, could we append "Before using this dataloader, please accept the acknowledgement at https://huggingface.co/datasets/bigscience-data/roots_vi_ted_talks_iwslt and use huggingface-cli login for authentication." to the _DESCRIPTION?

also remove train-00000-of-00001.parquet file from data directory and change _LOCAL to false
