Dataset Features

• Read (and write) from HF Storage Buckets: load raw data, process and save to Dataset Repos by @​lhoestq in huggingface/datasets#8064

  from datasets import load_dataset
  # load raw data from a Storage Bucket on HF
  ds = load_dataset("buckets/username/data-bucket", data_files=["*.jsonl"])
  # or manually, using hf:// paths
  ds = load_dataset("json", data_files=["hf://buckets/username/data-bucket/*.jsonl"])
  # process, filter
  ds = ds.map(...).filter(...)
  # publish the AI-ready dataset
  ds.push_to_hub("username/my-dataset-ready-for-training")

  This also fixes multiprocessed push_to_hub on macos that was causing segfault (now it uses spawn instead of fork). And it bumps dill and multiprocess versions to support python 3.14

• Datasets streaming iterable packaged improvements and fixes by @​Michael-RDev in huggingface/datasets#8068

  • added max_shard_size to IterableDataset.push_to_hub (but requires iterating twice to know the full dataset twice - improvements are welcome)
