Serialize N
-minibatch SparseTensor
into an [N, 3]
Tensor
.
tf.io.serialize_many_sparse(
sp_input, name=None, out_type=tf.dtypes.string
)
The SparseTensor
must have rank R
greater than 1, and the first dimension
is treated as the minibatch dimension. Elements of the SparseTensor
must be sorted in increasing order of this first dimension. The serialized
SparseTensor
objects going into each row of the output Tensor
will have
rank R-1
.
The minibatch size N
is extracted from sparse_shape[0]
.
Args |
sp_input
|
The input rank R SparseTensor .
|
name
|
A name prefix for the returned tensors (optional).
|
out_type
|
The dtype to use for serialization.
|
Returns |
A matrix (2-D Tensor ) with N rows and 3 columns. Each column
represents serialized SparseTensor 's indices, values, and shape
(respectively).
|
Raises |
TypeError
|
If sp_input is not a SparseTensor .
