Creates a dataset that asynchronously prefetches elements from input_dataset
.
tf.raw_ops.PrefetchDataset( input_dataset, buffer_size, output_types, output_shapes, slack_period=0, legacy_autotune=True, name=None )
Args | |
---|---|
input_dataset | A Tensor of type variant . |
buffer_size | A Tensor of type int64 . The maximum number of elements to buffer in an iterator over this 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 . |
slack_period | An optional int . Defaults to 0 . |
legacy_autotune | An optional bool . Defaults to True . |
name | A name for the operation (optional). |
Returns | |
---|---|
