|
|
Args |
|---|
cluster_resolver
|
A tf.distribute.cluster_resolver.TPUClusterResolver,
which provides information about the TPU cluster.
|
Returns |
|---|
|
The tf.tpu.Topology object for the topology of the TPU cluster. If called
inside tf.function, it returns the serialized topology object instead.
|
Raises |
|---|
RuntimeError
|
If running inside a tf.function.
|
NotFoundError
|
If no TPU devices found in eager mode.
