    Both the embedding op and compile op are assumed to be wrapped in separate
    tf_device.launch() ops. This is because the embedding op is head outside
    compiled and the compile op is wrapped in launch to execute on host
    during TPURewritePass.

    For example, the tf.OpA with the `mini_batch_splits` attribute will be
