Run options for

This can be used to hold some strategy specific configs.

experimental_enable_dynamic_batch_size Boolean. 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_shape Boolean. 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_options A tf.tpu.XLAOptions instance. Only applies to TPUStrategy. Controls the XLA compiling options on TPUs. Default to None.
