||
=================
|
||
|
||
该模块提供了加载和处理各种通用数据集的API，如MNIST、CIFAR-10、CIFAR-100、VOC、COCO、ImageNet、CelebA、CLUE等，
|
||
也支持加载业界标准格式的数据集，包括MindRecord、TFRecord、Manifest等。此外，用户还可以使用此模块定义和加载自己的数据集。
|
||
|
||
该模块还提供了在加载时进行数据采样的API，如SequentialSample、RandomSampler、DistributedSampler等。
|
||
|
||
大多数数据集可以通过指定参数 `cache` 启用缓存服务，以提升整体数据处理效率。
|
||
请注意Windows平台上还不支持缓存服务，因此在Windows上加载和处理数据时，请勿使用。更多介绍和限制，
|
||
请参考 `Single-Node Tensor Cache <https://www.mindspore.cn/docs/programming_guide/zh-CN/master/cache.html>`_。
