tf.compat.v1.tpu.initialize_system

Initializes a distributed TPU system for use with TensorFlow.

tf.compat.v1.tpu.initialize_system(
    embedding_config: Optional[embedding_pb2.TPUEmbeddingConfiguration] = None,
    job: Optional[Text] = None,
    compilation_failure_closes_chips: bool = True,
    tpu_cancellation_closes_chips: Optional[bool] = None
) -> core_types.Tensor

Args
embedding_config	If not None, a TPUEmbeddingConfiguration proto describing the desired configuration of the hardware embedding lookup tables. If embedding_config is None, no hardware embeddings can be used.
job	The job (the XXX in TensorFlow device specification /job:XXX) that contains the TPU devices that will be initialized. If job=None it is assumed there is only one job in the TensorFlow flock, and an error will be returned if this assumption does not hold.
compilation_failure_closes_chips	Set the configuration whether we want to close TPU chips when there is a compilation failure.
tpu_cancellation_closes_chips	Set the configuration whether we want to close TPU chips when a TPU execution is cancelled. If the value is None, the behavior will be determined by the command line flag tpu_cancellation_closes_chips for the TPU worker. WARNING: this argument only applies to TFRT TPU runtime.

Returns
A serialized TopologyProto that describes the TPU system. Note: the topology must be evaluated using Session.run before it can be used.
