1.9.0 (2020-06-19)

MLflow 1.9.0 includes numerous major features and improvements, and a breaking change to
experimental APIs:

Breaking Changes:

  • The new_name argument to MlflowClient.update_registered_model
    has been removed. Call MlflowClient.rename_registered_model instead. (#2946, @mparkhe)
  • The stage argument to MlflowClient.update_model_version
    has been removed. Call MlflowClient.transition_model_version_stage instead. (#2946, @mparkhe)

Features (MLflow Models and Flavors)

  • log_model and save_model APIs now support saving model signatures (the model's input and output schema)
    and example input along with the model itself (#2698, #2775, @tomasatdatabricks). Model signatures are used
    to reorder and validate input fields when scoring/serving models using the pyfunc flavor, mlflow models
    CLI commands, or mlflow.pyfunc.spark_udf (#2920, @tomasatdatabricks and @aarondav)
  • Introduce fastai model persistence and autologging APIs under mlflow.fastai (#2619, #2689 @antoniomdk)
  • Add pluggable mlflow.deployments API and CLI for deploying models to custom serving tools, e.g. RedisAI
    (#2327, @hhsecond)
  • Enables loading and scoring models whose conda environments include dependencies in conda-forge (#2797, @dbczumar)
  • Add support for scoring ONNX-persisted models that return Python lists (#2742, @andychow-db)

Features (MLflow Projects)

  • Add plugin interface for executing MLflow projects against custom backends (#2566, @jdlesage)
  • Add ability to specify additional cluster-wide Python and Java libraries when executing
    MLflow projects remotely on Databricks (#2845, @pogil)
  • Allow running MLflow projects against remote artifacts stored in any location with a corresponding
    ArtifactRepository implementation (Azure Blob Storage, GCS, etc) (#2774, @trangevi)
  • Allow MLflow projects running on Kubernetes to specify a different tracking server to log to via the
    KUBE_MLFLOW_TRACKING_URI for passing a different tracking server to the kubernetes job (#2874, @catapulta)

Features (UI)

  • Significant performance and scalability improvements to metric comparison and scatter plots in
    the UI (#2447, @mjlbach)
  • The main MLflow experiment list UI now includes a link to the model registry UI (#2805, @zhidongqu-db),
  • Enable viewing PDFs logged as artifacts from the runs UI (#2859, @ankmathur96)
  • UI accessibility improvements: better color contrast (#2872, @Zangr), add child roles to DOM elements (#2871, @Zangr)

Features (Tracking Client and Server)

  • Adds ability to pass client certs as part of REST API requests when using the tracking or model
    registry APIs. (#2843, @PhilipMay)
  • New community plugin: support for storing artifacts in Aliyun (Alibaba Cloud) (#2917, @SeaOfOcean)
  • Infer and set content type and encoding of objects when logging models and artifacts to S3 (#2881, @hajapy)
  • Adds support for logging artifacts to HDFS Federation ViewFs (#2782, @fhoering)
  • Add healthcheck endpoint to the MLflow server at /health (#2725, @crflynn)
  • Improves performance of default file-based tracking storage backend by using LibYAML (if installed)
    to read experiment and run metadata (#2707, @Higgcz)

Bug fixes and documentation updates:

  • Several UI fixes: remove margins around icon buttons (#2827, @harupy),
    fix alignment issues in metric view (#2811, @zhidongqu-db), add handling of NaN
    values in metrics plot (#2773, @dbczumar), truncate run ID in the run name when
    comparing multiple runs (#2508, @harupy)
  • Database engine URLs are no longer logged when running mlflow db upgrade (#2849, @hajapy)
  • Updates log_artifact, log_model APIs to consistently use posix paths, rather than OS-dependent
    paths, when computing artifact subpaths. (#2784, @mikeoconnor0308)
  • Fix ValueError when scoring tf.keras 1.X models using mlflow.pyfunc.predict (#2762, @juntai-zheng)
  • Fixes conda environment activation bug when running MLflow projects on Windows (#2731, @MynherVanKoek)
  • mlflow.end_run will now clear the active run even if the run cannot be marked as
    terminated (e.g. because it's been deleted), (#2693, @ahmed-shariff)
  • Add missing documentation for mlflow.spacy APIs (#2771, @harupy)
