tf.contrib.tpu.initialize_system(
embedding_config=None,
job=None
)
Defined in tensorflow/contrib/tpu/python/tpu/tpu.py
.
Initializes a distributed TPU system for use with TensorFlow.
Args:
embedding_config
: If not None, aTPUEmbeddingConfiguration
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.
Returns:
A serialized TopologyProto
that describes the TPU system. Note:
the topology must be evaluated using Session.run
before it can be used.
