Represents options for tf.data.Dataset.
Used in the tutorials:
Options object can be, for instance, used to control which static
optimizations to apply or whether to use performance modeling to dynamically
tune the parallelism of operations such as
After constructing an
Options object, use
apply the options to a dataset.
dataset = tf.data.Dataset.range(3) options = tf.data.Options()
Set options here.
dataset = dataset.with_options(options)
Initialize self. See help(type(self)) for accurate signature.
Whether the outputs need to be produced in deterministic order. If None, defaults to True.
The distribution strategy options associated with the dataset. See
tf.data.experimental.DistributeOptions for more details.
By default, tf.data will refuse to serialize a dataset or checkpoint its iterator if the dataset contains a stateful op as the serialization / checkpointing won't be able to capture its state. Users can -- at their own risk -- override this restriction by explicitly specifying that they are fine throwing away the state in these ops. There are three settings available - IGNORE: in which wecompletely ignore any state; WARN: We warn the user that some state might be thrown away; FAIL: We fail if any state is being captured.
The optimization options associated with the dataset. See
tf.data.experimental.OptimizationOptions for more details.
Whether to introduce 'slack' in the last
prefetch of the input pipeline, if it exists. This may reduce CPU contention with accelerator host-side activity at the start of a step. The slack frequency is determined by the number of devices attached to this input pipeline. If None, defaults to False.
The statistics options associated with the dataset. See
tf.data.experimental.StatsOptions for more details.
The threading options associated with the dataset. See
tf.data.experimental.ThreadingOptions for more details.
