the above function，as we use cgroupRoots to create cadvisor interface，the wrong parameter cgroupRoots will lead eviction manager not  to collect metric from /docker, then kubelet frequently print those error：

        should switch to
        `tf.estimator.Estimator.experimental_export_all_saved_models`.
*   tf.data:
    *   Add `tf.data.experimental.StatsOptions()`, to configure options to
        collect statistics from `tf.data.Dataset` pipeline using
        `StatsAggregator`. Add nested option, `experimental_stats` (which takes
        a `tf.data.experimen tal.StatsOptions` object), to `tf.data.Options`.
