mindspore.nn.GetNextSingleOp

class mindspore.nn.GetNextSingleOp(dataset_types, dataset_shapes, queue_name)

Cell to run for getting the next operation.

Parameters

• dataset_types (list[mindspore.dtype]) – The types of dataset.

• dataset_shapes (list[tuple[int]]) – The shapes of dataset.

• queue_name (str) – Queue name to fetch the data.

For detailed information, refer to ops.operations.GetNext.

Inputs:

No inputs.

Outputs:

tuple[Tensor], the data get from Dataset.

Supported Platforms:

Ascend GPU

Examples

>>> train_dataset = create_custom_dataset()
>>> dataset_helper = mindspore.DatasetHelper(train_dataset, dataset_sink_mode=True)
>>> dataset = dataset_helper.iter.dataset
>>> dataset_types, dataset_shapes = dataset_helper.types_shapes()
>>> queue_name = dataset.__transfer_dataset__.queue_name
>>> get_next_single_op_net = nn.GetNextSingleOp(dataset_types, dataset_shapes, queue_name)
>>> data, label = get_next_single_op_net()
>>> relu = P.ReLU()
>>> result = relu(data).asnumpy()
>>> print(result.shape)
