在训练期间，除用户提供的值外，Tune还将自动记录以下指标。 所有这些都可以用作停止条件，或作为参数传递给Trial Schedulers / Search Algorithms。

•  done: True if the trial has been finished, False otherwise
• iterations_since_restore: The number of times tune.report()/trainable.train() has been called after restoring the worker from a checkpoint
• time_since_restore: Time in seconds since restoring from a checkpoint.
• time_this_iter_s: Runtime of the current training iteration in seconds
