Decodes a variant
Tensor into a RaggedTensor
.
tf.raw_ops.RaggedTensorFromVariant( encoded_ragged, input_ragged_rank, output_ragged_rank, Tvalues, Tsplits=tf.dtypes.int64, name=None )
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.
Args | |
---|---|
encoded_ragged | A Tensor of type variant . A variant Tensor containing encoded RaggedTensor s. |
input_ragged_rank | An int that is >= -1 . 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) |
output_ragged_rank | An int that is >= 0 . The expected ragged rank of the output RaggedTensor . The following must hold: output_ragged_rank = rank(encoded_ragged) + input_ragged_rank . |
Tvalues | A tf.DType . |
Tsplits | An optional tf.DType from: tf.int32, tf.int64 . Defaults to tf.int64 . |
name | A name for the operation (optional). |
Returns | |
---|---|
A tuple of Tensor objects (output_nested_splits, output_dense_values). | |
output_nested_splits | A list of output_ragged_rank Tensor objects with type Tsplits . |
output_dense_values | A Tensor of type Tvalues . |
