workerType property
Specifies the type of virtual machine to use for your training job's worker nodes.
The supported values are the same as those described in the entry for
masterType. This value must be consistent with the category of machine
type that masterType uses. In other words, both must be Compute Engine
machine types or both must be legacy machine types. If you use cloud_tpu
for this value, see special instructions for [configuring a custom TPU
machine](/ml-engine/docs/tensorflow/using-tpus#configuring_a_custom_tpu_machine).
This value must be present when scaleTier is set to CUSTOM and
workerCount is greater than zero.
Optional.
