When configuring the CLIReporter for a trial, for instance with

```auto
tune.run(..., progress_reporter=CLIReporter(metric_columns=["date", "training_iteration", "timesteps_total"])

```

it would be nice to be able to report evaluation metrics. The results of the evaluation are nested like this `result["evaluation"]["episode_reward_mean"]` and this is therefore not possible to access them.

Hmm, I think you can do `evaluation/episode_reward_mean` to get nested metrics?

Unfortunately, it is not working. I have digged a bit into the code of the CLIReporter and there is only a get call on the results dictionary, therefore it is not possible to report nested metrics.

Maybe is this a feature that is already implemented in some upcoming version ? (I am using ray 1.1.0)

Hmm, I see – could you help post a feature request about this on Github?
