Hello! I am trying to load the Python subset of the dataset. It raises a NonMatchingSplitsSizesError 15% into loading the dataset.

>>> import datasets
>>> ds = datasets.load_dataset("bigcode/the-stack-v2", data_dir="data/Python", split="train")
Generating train split:  15%|_____________                                                                          | 96448523/664910862 [02:09<12:41, 746839.37 examples/s]

Is this a known issue? I'm on the latest datasets version: datasets==2.18.0
