Represents options for tf.data.Dataset.
tf.data.Options()
An Options object can be, for instance, used to control which graph
optimizations to apply or whether to use performance modeling to dynamically
tune the parallelism of operations such as tf.data.Dataset.map or
tf.data.Dataset.interleave.
After constructing an Options object, use dataset.with_options(options) to
apply the options to a dataset.
dataset = tf.data.Dataset.range(3)options = tf.data.Options()# Set options here.dataset = dataset.with_options(options)
Attributes | |
|---|---|
experimental_deterministic
|
Whether the outputs need to be produced in deterministic order. If None, defaults to True. |
experimental_distribute
|
The distribution strategy options associated with the dataset. See tf.data.experimental.DistributeOptions for more details.
|
experimental_external_state_policy
|
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. |
experimental_optimization
|
The optimization options associated with the dataset. See tf.data.experimental.OptimizationOptions for more details.
|
experimental_slack
|
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.
|
experimental_stats
|
The statistics options associated with the dataset. See tf.data.experimental.StatsOptions for more details.
|
experimental_threading
|
The threading options associated with the dataset. See tf.data.experimental.ThreadingOptions for more details.

Methods
merge
merge(
options
)
Merges itself with the given tf.data.Options.
The given tf.data.Options can be merged as long as there does not exist an
attribute that is set to different values in self and options.
| Args | |
|---|---|
options
|
a tf.data.Options to merge with
|
| Raises | |
|---|---|
ValueError
|
if the given tf.data.Options cannot be merged
|
| Returns | |
|---|---|
New tf.data.Options() object which is the result of merging self with
the input tf.data.Options.
|
__eq__
__eq__(
other
)
Return self==value.
__ne__
__ne__(
other
)
Return self!=value.
