Loaders for various machine learning datasets for testing and example scripts. Previously in thinc.extra.datasets. Loaders can be imported directly or used via their string name (which is useful if they're set via command line arguments). Some loaders may take arguments – see the source of details. # Import directly from ml_datasets import imdb train_data, dev_data = imdb() # Load via registry from ml_datasets import loaders imdb_loader = loaders.get("imdb") train_data, dev_data = imdb_loader() github地址： https://github.com/explosion/ml-datasets
