# Differences with torchtext.datasets.AG_NEWS [](https://gitee.com/mindspore/docs/blob/master/docs/mindspore/source_en/note/api_mapping/pytorch_diff/AGNEWS.md) ## torchtext.datasets.AG_NEWS ```python class torchtext.datasets.AG_NEWS( root: str = '.data', split: Union[List[str], str] = ('train', 'test')) ``` For more information, see [torchtext.datasets.AG_NEWS](https://pytorch.org/text/0.9.0/datasets.html#ag-news). ## mindspore.dataset.AGNewsDataset ```python class mindspore.dataset.AGNewsDataset( dataset_dir, usage=None, num_samples=None, num_parallel_workers=None, shuffle=Shuffle.GLOBAL, num_shards=None, shard_id=None, cache=None) ``` For more information, see [mindspore.dataset.AGNewsDataset](https://mindspore.cn/docs/en/master/api_python/dataset/mindspore.dataset.AGNewsDataset.html#mindspore.dataset.AGNewsDataset). ## Differences PyTorch: Read the AG News dataset. MindSpore: Read the AG News dataset.
