Comments: the same issue with datasets.load_dataset("iwslt2017", 'iwslt2017-en-nl', split=split), ..... 

even with setting master like the following command, still remains 

datasets.load_dataset("iwslt2017", 'iwslt2017-en-nl', split="train", script_version="master")


Looks like the data has been moved from its original location to google drive

New url: https://drive.google.com/u/0/uc?id=12ycYSzLIG253AFN35Y6qoyf9wtkOjakp&export=download
