Is there any implementation available that integrates the DARTS search space from this [paper](https://arxiv.org/abs/1806.09055) into Ray Tune? I have a hard time rewriting the search space into the config dictionary format and the only [implementation](https://github.com/yeshg/RayNAS/) I found on the web seems to be incomplete.

Would be quite interesting to benchmark the search algorithms in Ray Tune with this search space.

Can you say a bit about what is incomplete about the implementation?

My understanding also is that DARTS won’t benefit out of the box from parallelism provided by Ray Tune.
