Update README.md
The indentation in the .yaml config is wrong. This leads to an "KeyError: name" when loading the Dataset via load_dataset().
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.
