Serialize a SparseTensor into a 3-vector (1-D Tensor) object.
    sp_input, out_type=tf.dtypes.string, name=None


  • sp_input: The input SparseTensor.
  • out_type: The dtype to use for serialization.
  • name: A name prefix for the returned tensors (optional).


A 3-vector (1-D Tensor), with each column representing the serialized SparseTensor's indices, values, and shape (respectively).


  • TypeError: If sp_input is not a SparseTensor.
