We are happy to announce the availability of MLflow 0.4.0!

MLflow Release 0.4.0 is ready, released 2018-08-01. The release is available on PyPI and docs are updated. Here are the release notes (also available on GitHub):

Breaking changes:

• [Projects] Removed the use_temp_cwd argument to mlflow.projects.run() (--new-dir flag in the mlflow run CLI). Runs of local projects now use the local project directory as their working directory. Git projects are still fetched into temporary directories (#215, @smurching)
• [Tracking] GCS artifact storage is now a pluggable dependency (no longer installed by default). To enable GCS support, install google-cloud-storage on both the client and tracking server via pip (#202, @smurching).
• [Tracking] Clients running MLflow 0.4.0 and above require a server running MLflow 0.4.0 or above, due to a fix that ensures clients no longer double-serialize JSON into strings when sending data to the server (#200, @aarondav). However, the MLflow 0.4.0 server remains backwards-compatible with older clients (#216, @aarondav)

Features:

• [Examples] Add a more advanced tracking example: using MLflow with PyTorch and TensorBoard (#203)
• [Models] H2O model support (#170, @ToonKBC)
• [Projects] Support for running projects in subdirectories of Git repos (#153, @juntai-zheng)
• [SageMaker] Support for specifying a compute specification when deploying to SageMaker (#185, @dbczumar)
• [Server] Added --static-prefix option to serve UI from a specified prefix to MLflow UI and server (#116, @andrewmchen)
• [Tracking] Azure blob storage support for artifacts (#206, @mateiz)
• [Tracking] Add support for Databricks-backed RestStore (#200, @aarondav)
• [UI] Enable productionizing frontend by adding CSRF support (#199, @aarondav)
• [UI] Update metric and parameter filters to let users control column order (#186, @mateiz)

Bug fixes:

• Fixed incompatible file structure returned by GCSArtifactRepository (#173, @jakeret)
• Fixed metric values going out of order on x axis (#204, @mateiz)
• Fixed occasional hanging behavior when using the projects.run API (#193, @smurching)
• Miscellaneous bug and documentation fixes from @aarondav, @andrewmchen, @arinto, @jakeret, @mateiz, @smurching, @stbof

We are happy to announce the availability of MLflow 0.3.0!

MLflow Release 0.3.0 is ready, released 2018-07-18. The release is available on PyPI and docs are updated. Here are the release notes:

Breaking changes:

• [MLflow Server] Renamed --artifact-root parameter to --default-artifact-root in mlflow server to better reflect its purpose (#165, @aarondav)

Features:

• Spark MLlib integration: we now support logging SparkML Models directly in the log_model API, model format, and serving APIs (#72, @tomasatdatabricks)
• Google Cloud Storage is now supported as an artifact storage root (#152, @bnekolny)
• Support asychronous/parallel execution of MLflow runs (#82, @smurching)
• [SageMaker] Support for deleting, updating applications deployed via SageMaker (#145, @dbczumar)
• [SageMaker] Pushing the MLflow SageMaker container now includes the MLflow version that it was published with (#124, @sueann)
• [SageMaker] Simplify parameters to SageMaker deploy by providing sane defaults (#126, @sueann)
• [UI] One-element metrics are now displayed as a bar char (#118, @cryptexis)

Bug fixes:

• Require gitpython>=2.1.0 (#98, @aarondav)
• Fixed TensorFlow model loading so that columns match the output names of the exported model (#94, @smurching)
• Fix SparkUDF when number of columns >= 10 (#97, @aarondav)
• Miscellaneous bug and documentation fixes from @emres, @dmatrix, @stbof, @gsganden, @dennyglee, @anabranch, @mikehuston, @andrewmchen, @juntai-zheng

• Added mlflow server to provide a remote tracking server. This is akin to mlflow ui with new options:
  • --host to allow binding to any ports (#27, @mdagost)
  • --artifact-root to allow storing artifacts at a remote location, S3 only right now (#78, @mateiz)
• Server now runs behind gunicorn to allow concurrent requests to be made (#61, @mateiz)
• Tensorflow integration: we now support logging Tensorflow Models directly in the log_model API, model format, and serving APIs (#28, @juntai-zheng)
• Added experiments.list_experiments as part of experiments API (#37, @mparkhe)
• Improved support for unicode strings (#79, @smurching)
• Diabetes progression example dataset and training code (#56, @dennyglee)
