tf.compat.v1.raw_ops.LegacyParallelInterleaveDatasetV2

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!

Args
input_dataset	A Tensor of type variant.
other_arguments	A list of Tensor objects.
cycle_length	A Tensor of type int64.
block_length	A Tensor of type int64.
buffer_output_elements	A Tensor of type int64.
prefetch_input_elements	A Tensor of type int64.
f	A function decorated with @Defun. A function mapping elements of input_dataset, concatenated with other_arguments, to a Dataset variant that contains elements matching output_types and output_shapes.
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.
deterministic	An optional string. Defaults to "default".
name	A name for the operation (optional).

Returns
A Tensor of type variant.
