CacheDataset

public final class CacheDataset

Creates a dataset that caches elements from `input_dataset`.

A CacheDataset will iterate over the input_dataset, and store tensors. If the cache already exists, the cache will be used. If the cache is inappropriate (e.g. cannot be opened, contains tensors of the wrong shape / size), an error will the returned when used.

Constant Value: "CacheDataset"

Public Methods

public Output<TType> asOutput ()

Returns the symbolic handle of the 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.

public static CacheDataset create (Scope scope, Operand<?> inputDataset, Operand<TString> filename, List<Class<? extends TType>> outputTypes, List<Shape> outputShapes)

Factory method to create a class wrapping a new CacheDataset operation.

Parameters

scope	current scope
filename	A path on the filesystem where we should cache the dataset. Note: this will be a directory.

Returns

• a new instance of CacheDataset

public Output<?> handle ()
