tf.raw_ops.ParallelMapDatasetV2

Creates a dataset that applies f to the outputs of input_dataset.

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.
