from datasets import load_dataset

queries = load_dataset('irds/mmarco_v2_it_train', 'queries')
for record in queries:
record # {'query_id': ..., 'text': ...}

qrels = load_dataset('irds/mmarco_v2_it_train', 'qrels')
for record in qrels:
record # {'query_id': ..., 'doc_id': ..., 'relevance': ..., 'iteration': ...}

docpairs = load_dataset('irds/mmarco_v2_it_train', 'docpairs')
for record in docpairs:
