The proposed changes seem to give a different error:

from datasets import load_dataset
dataset = load_dataset("allenai/paloma", revision="2482a6ade69f509af04ca4ec26e6979913e24a21")

Yields this error:

I had the same issue. But after spending some hours on finding the bug in the .yaml, I decided to just download the dataset and write my own dataloader around this snippet that loads the .jsonl.gz files:

def load_jsonl_gz(file_path: Path) -> list[dict[str, Any]]:
    with gzip.open(file_path, "rt") as f:
        return [json.loads(line) for line in f]

I suspect that one still needs to adapt the .yaml file or write a loader script similar to the dolma dataset: https://huggingface.co/datasets/allenai/dolma/blob/main/dolma.py.

Thanks so much pointing out this issue and sorry I didn't see this PR before (something wrong with my notification settings). I've merged your fix to the indentation in along with some other changes I made to support loading using HF datasets.
