tf.raw_ops.ParallelMapDataset
Creates a dataset that applies f to the outputs of input_dataset.
tf.raw_ops.ParallelMapDataset(
input_dataset, other_arguments, num_parallel_calls, f, output_types,
output_shapes, use_inter_op_parallelism=True, sloppy=False,
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 int32. 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. |
sloppy | An optional bool. Defaults to False. |
preserve_cardinality | An optional bool. Defaults to False. |
name | A name for the operation (optional). |
| Returns | |
|---|---|
A Tensor of type variant. |
