Parallelize Hyperopt hyperparameter tuning

Note

The open-source version of Hyperopt is no longer being maintained.

Hyperopt will be removed in the next major DBR ML version. Databricks recommends using Optuna for a similar experience and access to more up-to-date hyperparameter tuning algorithms.

This notebook shows how to use Hyperopt to parallelize hyperparameter tuning calculations. It uses the SparkTrials class to automatically distribute calculations across the cluster workers. It also illustrates automated MLflow tracking of Hyperopt runs so you can save the results for later.
