tf.raw_ops.MapAndBatchDataset(
    input_dataset,
    other_arguments,
    batch_size,
    num_parallel_calls,
    drop_remainder,
    f,
    output_types,
    output_shapes,
    preserve_cardinality=False,
    metadata='',
    name=None
)

Creates a dataset that applies f to the outputs of input_dataset and then batches batch_size of them.

Unlike a "MapDataset", which applies f sequentially, this dataset invokes up to batch_size * num_parallel_batches copies of f in parallel.

Args
input_dataset	A Tensor of type variant. A variant tensor representing the input dataset.
other_arguments	A list of Tensor objects. A list of tensors, typically values that were captured when building a closure for f.
batch_size	A Tensor of type int64. A scalar representing the number of elements to accumulate in a batch. It determines the number of concurrent invocations of f that process elements from input_dataset in parallel.
num_parallel_calls	A Tensor of type int64. A scalar representing the maximum number of parallel invocations of the map_fnfunction. Applying the map_fn on consecutive input elements in parallel has the potential to improve input pipeline throughput.
drop_remainder	A Tensor of type bool. A scalar representing whether the last batch should be dropped in case its size is smaller than desired.
f	A function decorated with @Defun. A function to apply to the outputs of input_dataset.
output_types	A list of tf.DTypes that has length >= 1.
output_shapes	A list of shapes (each a tf.TensorShape or list of ints) that has length >= 1.
preserve_cardinality	An optional bool. Defaults to False.
metadata	An optional string. Defaults to "".
name	A name for the operation (optional).

Returns
A Tensor of type variant.
