Databricks Runtime 6.0 ML

Databricks released this image in October 2019.

Databricks Runtime 6.0 ML provides a ready-to-go environment for machine learning and data science based on Databricks Runtime 6.0. Databricks Runtime for ML contains many popular machine learning libraries, including TensorFlow, PyTorch, Keras, and XGBoost. It also supports distributed deep learning training using Horovod.

For more information, including instructions for creating a Databricks Runtime ML cluster, see Databricks Runtime for Machine Learning.

New features

Databricks Runtime 6.0 ML is built on top of Databricks Runtime 6.0. For information on what’s new in Databricks Runtime 6.0, see the Databricks Runtime 6.0 release notes.

Query MLflow experiment data at scale using the new MLflow Spark data source

The Spark data source for MLflow experiments now provides a standard API to load MLflow experiment run data. This enables large-scale querying and analysis of MLflow experiment data using DataFrame APIs. For a given experiment, the DataFrame contains run_ids, metrics, params, tags, start_time, end_time, status, and the artifact_uri for artifacts. See MLflow Experiment.

Improvements

  • Hyperopt GA

    Hyperopt on Azure Databricks is now generally available. Notable improvements since public preview include support for MLflow logging on Spark workers, correct handling of PySpark broadcast variables, as well as a new guide on model selection using Hyperopt. We also fixed small bugs in log messages, error handling, UI, and made our docs more reader friendly. Refer to the Hyperopt documentation for details.

    We have updated how Azure Databricks logs Hyperopt experiments so that you can now log a custom metric during Hyperopt runs by passing the metric to the mlflow.log_metric function (see log_metric). This is useful if you want to log custom metrics in addition to loss, which is logged by default when the hyperopt.fmin function is called.

  • MLflow

    • Added MLflow Java Client 1.2.0
    • MLflow is now promoted as a top-tier library
  • Upgraded machine learning libraries

    • Horovod upgraded from 0.16.4 to 0.18.1
    • MLflow upgraded from 1.0.0 to 1.2.0
  • Anaconda distribution upgraded from 5.2.0 to 2019.03

Removal

  • Databricks ML Model Export is removed. Use MLeap for importing and exporting models instead.

  • In the Hyperopt library, the following properties of hyperopt.SparkTrials are removed:

    • SparkTrials.successful_trials_count
    • SparkTrials.failed_trials_count
    • SparkTrials.cancelled_trials_count
    • SparkTrials.total_trials_count

    They are replaced with the following functions:

    • SparkTrials.count_successful_trials()
    • SparkTrials.count_failed_trials()
    • SparkTrials.count_cancelled_trials()
    • SparkTrials.count_total_trials()
