tf.distribute.RunOptions

Run options for strategy.run.

tf.distribute.RunOptions(
    experimental_enable_dynamic_batch_size=True,
    experimental_bucketizing_dynamic_shape=False,
    experimental_xla_options=None
)

This can be used to hold some strategy specific configs.

experimental_enable_dynamic_batch_sizeBoolean. Only applies to TPUStrategy. Default to True. If True, TPUStrategy will enable dynamic padder to support dynamic batch size for the inputs. Otherwise only static shape inputs are allowed.
experimental_bucketizing_dynamic_shapeBoolean. Only applies to TPUStrategy. Default to False. If True, TPUStrategy will automatic bucketize inputs passed into run if the input shape is dynamic. This is a performance optimization to reduce XLA recompilation, which should not have impact on correctness.
experimental_xla_optionsA tf.tpu.XLAOptions instance. Only applies to TPUStrategy. Controls the XLA compiling options on TPUs. Default to None.
