RaggedTensorFromVariant

public final class RaggedTensorFromVariant

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.

Public Methods

public static RaggedTensorFromVariant<Long, T> create (Scope scope, Operand<?> encodedRagged, Long inputRaggedRank, Long outputRaggedRank, Class<T> Tvalues)

Factory method to create a class wrapping a new RaggedTensorFromVariant operation using default output types.

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`.
Returns
  • a new instance of RaggedTensorFromVariant
