Last I checked it wasn't easy to use something like optuna to do hyperparameter tuning with hydra/DVC.
Ideally I'd like the tool I use for data versioning (DVC/git-lfs/gif-annex) to be orthogonal to that which I use for hyperparameter sweeping (DVD/optuna/SageMaker experiments), and orthogonal to that which I use for configuration management (DVC/Hydra/Plain YAML), to that what I use for experimental DAG management (DVC/Makefile)
Optuna is becoming very popular in the data-science/deep learning ecosystem at the moment. It would be great to see more composable tools, rather than having to opt all-in into a given ecosystem.
Love the work that DVC is doing though to tackle these difficult problems though!
