tf.compat.v1.raw_ops.ParallelMapDatasetV2

tf.raw_ops.ParallelMapDatasetV2(
    input_dataset, other_arguments, num_parallel_calls, f, output_types,
    output_shapes, use_inter_op_parallelism=True, deterministic='default',
    preserve_cardinality=False, name=None
)

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

Args
input_dataset	A Tensor of type variant.
other_arguments	A list of Tensor objects.
num_parallel_calls	A Tensor of type int64. The number of concurrent invocations of f that process elements from input_dataset in parallel.
f	A function decorated with @Defun.
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.
use_inter_op_parallelism	An optional bool. Defaults to True.
deterministic	An optional string. Defaults to "default".
preserve_cardinality	An optional bool. Defaults to False.
name	A name for the operation (optional).

Returns
A Tensor of type variant.
