Datasets:

mc4

like 141

Hi,

I'm encountering an eof error when trying to download the Vietnamese dataset. Does anyone know a workaround for this error? I encountered no issues with other languages.

Code:

from datasets import load_dataset
data = load_dataset("mc4", languages=["vi"])

Error message:
