Creates a dataset that applies f
to the outputs of input_dataset
.
tf.raw_ops.LegacyParallelInterleaveDatasetV2( input_dataset, other_arguments, cycle_length, block_length, buffer_output_elements, prefetch_input_elements, f, output_types, output_shapes, deterministic='default', name=None )
The resulting dataset is similar to the InterleaveDataset
, with the exception that if retrieving the next value from a dataset would cause the requester to block, it will skip that input dataset. This dataset is especially useful when loading data from a variable-latency datastores (e.g. HDFS, GCS), as it allows the training step to proceed so long as some data is available.
!! WARNING !! This dataset is not deterministic!
