**How severe does this issue affect your experience of using Ray?**

- Low: It annoys or frustrates me for a moment.

Hello, I am fairly new to ray and I try to use Tuner with `log_to_file` option from the RunConfig.

As I can see in the [documentation](https://docs.ray.io/en/latest/tune/tutorials/tune-output.html#where-to-find-log-to-file-files) using this option, print statements for example should be captured and stored in trial directories in corresponding files that are created.

I have adapted the code of a basic example to include two print statements and run with the desired option into [google colab](https://colab.research.google.com/drive/1OoiQd8RU9QHcKpecCPN2y3MQUnxMr4gt?usp=sharing). In this particular example I expect that stdout files are created inside the trial folders, along with `result.json` etc. However I can’t see any such files and the prints happen in the console. Am I missing something, or is there a configuration which overrides `log_to_file` somewhere?

Thanks
