Op

public final class RaggedTensorFromVariant<U extends Number,T>
extends PrimitiveOp

Decodes a `variant` Tensor into a `RaggedTensor`.

Decodes the given `variant` Tensor and returns a `RaggedTensor`. The input could be a scalar, meaning it encodes a single `RaggedTensor` with ragged_rank `output_ragged_rank`. It could also have an arbitrary rank, in which case each element is decoded into a `RaggedTensor` with ragged_rank `input_ragged_rank` and these are then stacked according to the input shape to output a single `RaggedTensor` with ragged_rank `output_ragged_rank`. Each `variant` element in the input Tensor is decoded by retrieving from the element a 1-D `variant` Tensor with `input_ragged_rank + 1` Tensors, corresponding to the splits and values of the decoded `RaggedTensor`. If `input_ragged_rank` is -1, then it is inferred as `output_ragged_rank` - `rank(encoded_ragged)`. See `RaggedTensorToVariant` for the corresponding encoding logic.

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

Parameters:

scope - current scope

encodedRagged - A `variant` Tensor containing encoded `RaggedTensor`s.

inputRaggedRank - The ragged rank of each encoded `RaggedTensor` component in the input. If set to -1, this is inferred as `output_ragged_rank` - `rank(encoded_ragged)`

outputRaggedRank - The expected ragged rank of the output `RaggedTensor`. The following must hold: `output_ragged_rank = rank(encoded_ragged) + input_ragged_rank`.

Tvalues -

Tsplits -

Returns:

a new instance of RaggedTensorFromVariant

outputNestedSplits

public List<Output<U>> outputNestedSplits()

A list of one or more Tensors representing the splits of the output `RaggedTensor`.

outputDenseValues

public Output<T> outputDenseValues()

A Tensor representing the values of the output `RaggedTensor`.
