Update datasets requirement from <2.7,>=2.2 to >=2.2,<2.9

[dependabot[bot]]

Updates the requirements on datasets to permit the latest version.

Release notes

Sourced from datasets's releases.

2.8.0

Important

• Removed YAML integer keys from class_label metadata by @​albertvillanova in huggingface/datasets#5277
  • From now on, datasets pushed on the Hub and using ClassLabel will use a new YAML model to store the feature types
  • The new model uses strings instead of integers for the ids in label name mapping (e.g. 0 -> "0"). This is due to the Hub limitations. In a few months the Hub may stop allowing users to push the old YAML model.
  • Old versions of datasets are not able to reload datasets pushed with this new model, so we encourage everyone to update.

Datasets Features

• Fix methods using IterableDataset.map that lead to features=None by @​alvarobartt in huggingface/datasets#5287
  • Datasets in streaming mode now update their features after column renaming or removal
• Add num_proc to from_csv/generator/json/parquet/text by @​lhoestq in huggingface/datasets#5239
  • Use multiprocessing to load multiple files in parallel
• Add features param to IterableDataset.map by @​alvarobartt in huggingface/datasets#5311
• Sharded save_to_disk + multiprocessing by @​lhoestq in huggingface/datasets#5268
  • Pass num_shards or max_shard_size to ds.save_to_disk() or ds.push_to_hub()
  • Pass num_proc to use multiprocessing.
• Support for decoding Image/Audio types in map when format type is not default one by @​mariosasko in huggingface/datasets#5252
• Support torch dataloader without torch formatting for IterableDataset by @​lhoestq in huggingface/datasets#5357
  • You can now pass any dataset in streaming mode to a PyTorch DataLoader directly:

  from datasets import load_dataset
  ds = load_dataset("c4", "en", streaming=True, split="train")
  dataloader = DataLoader(ds, batch_size=32, num_workers=4)
