[lhoestq]

There are 120k+ open datasets at https://huggingface.co/datasets that people can load using Dask.

For example to loadthe wikimedia/wikipedia dataset:

import dask.dataframe as dd
df = dd.read_parquet("hf://datasets/wikimedia/wikipedia/20231101.en")

Btw we plan to show code snippets on dataset pages on HF on how to load with Dask !
