A Tensor of type int64.
A scalar representing the number of elements to accumulate in a
A list of at least 1 Tensor objects with type int64.
A list of int64 tensors representing the desired padded shapes
of the corresponding output components. These shapes may be partially
specified, using -1 to indicate that a particular dimension should be
padded to the maximum size of all batch elements.
A list of Tensor objects.
A list of scalars containing the padding value to use for
each of the outputs.
A Tensor of type bool.
A scalar representing whether the last batch should be dropped in case its size
is smaller than desired.
A list of shapes (each a tf.TensorShape or list of ints) that has length >= 1.
