Class SnapshotDataset

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.SnapshotDataset

All Implemented Interfaces:

Op, Operand<Object>

public final class SnapshotDataset
extends PrimitiveOp
implements Operand<Object>

Creates a dataset that will write to / read from a snapshot.

This dataset attempts to determine whether a valid snapshot exists at the `snapshot_path`, and reads from the snapshot in lieu of using `input_dataset`. If not, it will run the preprocessing pipeline as usual, and write out a snapshot of the data processed for future use.

handle

public Output<?> handle()

asOutput

public Output<Object> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<Object>
