Ragged Tensors.
This package defines ops for manipulating ragged tensors (tf.RaggedTensor
),
which are tensors with non-uniform shapes. In particular, each RaggedTensor
has one or more ragged dimensions, which are dimensions whose slices may have
different lengths. For example, the inner (column) dimension of
rt=[[3, 1, 4, 1], [], [5, 9, 2], [6], []]
is ragged, since the column slices
(rt[0, :]
, ..., rt[4, :]
) have different lengths. For a more detailed
description of ragged tensors, see the tf.RaggedTensor
class documentation
and the Ragged Tensor Guide.
Additional ops that support RaggedTensor
Arguments that accept RaggedTensor
s are marked in bold.
