class_docstr: Client for working with the Cloud TPU API.
  
  This client is intended to be used for resolving tpu name to ip addresses.
  
  It's recommended to use this library as a contextlib to utilize all
  functionality.
docstr: Returns true if the TPU is in a state where training should eventually resume.
  
  If false the TPU is in a unrecoverable state and should be recreated.
