tf.compat.v1.serialize_many_sparse

Serialize N-minibatch SparseTensor into an [N, 3] Tensor.

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
