v1.3.0#

Client/server matrix, prerequisites, and installing#

The MLRun server is now based on Python 3.9. It’s recommended to move the client to Python 3.9 as well.

MLRun v1.3.0 maintains support for mlrun base images that are based on python 3.7. To differentiate between the images, the images based on python 3.7 have the suffix: -py37. The correct version is automatically chosen for the built-in MLRun images according to the Python version of the MLRun client (for example, a 3.7 Jupyter gets the -py37 images).

MLRun is pre-installed in CE Jupyter.

To install on a Python 3.9 client, run:

./align_mlrun.sh

To install on a Python 3.7 client, run:

  1. Configure the Jupyter service with the env variable JUPYTER_PREFER_ENV_PATH=false.

  2. Within the Jupyter service, open a terminal and update conda and pip to have an up-to-date pip resolver.

   $CONDA_HOME/bin/conda install -y pip

  1. If you are going to work with python 3.9, create a new conda env and activate it:

    conda create -n python39 python=3.9 ipykernel -y
    conda activate python39

  1. Install mlrun:

./align_mlrun.sh

New and updated features#

Feature store#

ID

Description

ML-2592

Offline data can be registered as feature sets (Tech Preview). See Create a feature set without ingesting its data.

ML-2610

Supports SQLSource for batch ingestion (Tech Preview). See SQL data source.

ML-2610

Supports SQLTarget for storey engine (Tech Preview). (Spark is not yet supported.) See SQL target store.

ML-2709

The Spark engine now supports the steps: MapValues, Imputer, OneHotEncoder, DropFeatures; and supports extracting the time parts from the date in the DateExtractor step. See Data transformations.

ML-2802

get_offline_features supports Spark Operator and Remote Spark.

ML-2957

The username and password for the RedisNoSqlTarget are now configured using secrets, as <prefix_>REDIS_USER <prefix_>REDIS_PASSWORD where <prefix> is the optional RedisNoSqlTarget credentials_prefix parameter. See Redis target store.

ML-3008

Supports Spark using Redis as an online KV target, which caused a breaking change.

ML-3373

Supports creating a feature vector over several feature sets with different entity. (Outer joins are Tech Preview.) See Using an offline feature vector.

Logging data#

ID

Description

ML-2845

Logging data using hints. You can now pass data into MLRun and log it using log hints, instead of the decorator. This is the initial change in MLRun to simplify wrapping usable code into MLRun without having to modify it. Future releases will continue this paradigm shift. See more details.

Projects#

ID

Description

ML-3048

When defining a new project from scratch, there is now a default context directory: “./”. This is the directory from which the MLRun client runs, unless otherwise specified.

Serving graphs#

ID

Description

ML-1167

Add support for graphs that split and merge (DAG), including a list of steps for the after argument in the add_step() method. See Graph that splits and rejoins.

ML-2507

Supports configuring of consumer group name for steps following QueueSteps. See Queue (streaming).

Storey#

ID

Description

ML-2502

The event time in storey events is now taken from the timestamp_key. If the timestamp_key is not defined for the event, then the time is taken from the processing-time metadata. View in Git, and in Storey git.

UI#

ID

Description

ML-1186

The new Projects home page provides easy and intuitive access to the full project lifecycle in three phases, with links to the relevant wizards under each phase heading: ingesting and processing data, developing and training a model, deploying and monitoring the project.

NA

UI change log in GitHub

APIs#

ID

Description

ML-3104

These APIs now only return reasons in kwargs: log_and_raise, generic_error_handler, http_status_error_handler.

ML-3204

New API set_image_pull_configuration that modifies func.spec.image_pull_secret and func.spec.image_pull_policy, instead of directly accessing these values through the spec.

Documentation#

Improvements to Set up your environment.

Infrastructure improvements#

ID

Description

ML-2609

MLRun server is based on Python 3.9.

ML-2732

The new log collection service improves the performance and reduces heavy IO operations from the API container. The new MLRun log collector service is a gRPC server, which runs as sidecar in the mlrun-api pod (chief and worker). The service is responsible for collecting logs from run pods, writing to persisted files, and reading them on request. The new service is transparent to the end-user: there are no UI or API changes.

Breaking changes#

  • The behavior of ingest with aggregation changed in v1.3.0 (storey, spark, pandas engines). Now, when you ingest a “timestamp” column, it returns
    <class 'pandas._libs.tslibs.timestamps.Timestamp'>.
    Previously, it returned <class 'str'>

  • Any target data that was saved using Redis as an online target with storey engine (RedisNoSql target, introduced in 1.2.1) is not accessible after upgrading to v1.3. (Data ingested subsequent to the upgrade is unaffacted.)

Deprecated and removed APIs#

Starting with v1.3.0, and continuing in subsequent releases, obsolete functions are getting removed from the code.

  • The Kubernetes Pods tab in Monitor Workflows now shows the complete pod details. View in Git.

  • Update the tooltips in Projects | Jobs | Schedule to explain that day 0 (for cron jobs) is Monday, and not Sunday. View in Git.

  • Fix UI crash when selecting All in the Tag dropdown list of the Projects | Feature Store | Feature Vectors tab. View in Git.

  • Fix: now updates next_run_time when skipping scheduling due to concurrent runs. View in Git.

  • When creating a project, the error NotImplementedError was updated to explain that MLRun does not have a DB to connect to. View in Git.

  • When previewing a DirArtifact in the UI, it now returns the requested directory. Previously it was returning the directory list from the root of the container. View in Git.

  • Load source at runtime or build time now fully supports .zip files, which were not fully supported previously.

See more#

v1.2.0#

New and updated features#

Artifacts#

  • Support for artifact tagging:

    • SDK: Add tag_artifacts and delete_artifacts_tags that can be used to modify existing artifacts tags and have more than one version for an artifact.

    • UI: You can add and edit artifact tags in the UI.

    • API: Introduce new endpoints in /projects/<project>/tags.

Auth#

  • Support S3 profile and assume-role when using fsspec.

  • Support GitHub fine grained tokens.

Documentation#

  • Restructured, and added new content.

Feature store#

  • Support Redis as an online feature set for storey engine only. (See Redis target store.)

  • Fully supports ingesting with pandas engine, now equivalent to ingestion with storey engine (TechPreview):

    • Support DataFrame with multi-index.

    • Support mlrun steps when using pandas engine: OneHotEncoder , DateExtractor, MapValue, Imputer and FeatureValidation.

  • Add new step: DropFeature for pandas and storey engines. (TechPreview)

  • Add param query for get_offline_feature for filtering the output.

Frameworks#

  • Add HuggingFaceModelServer to mlrun.frameworks at mlrun.frameworks.huggingface to serve HuggingFace models.

Functions#

  • Add function.with_annotations({"framework":"tensorflow"}) to user-created functions.

  • Add overwrite_build_params to project.build_function() so the user can choose whether or not to keep the build params that were used in previous function builds.

  • deploy_function has a new option of mock deployment that allows running the function locally.

Installation#

  • New option to install google-cloud requirements using mlrun[google-cloud]: when installing MLRun for integration with GCP clients, only compatible packages are installed.

Models#

  • The Labels in the Models > Overview tab can be edited.

Internal#

  • Refactor artifacts endpoints to follow the MLRun convention of /projects/<project>/artifacts/.... (The previous API will be deprecated in a future release.)

  • Add /api/_internal/memory-reports/ endpoints for memory related metrics to better understand the memory consumption of the API.

  • Improve the HTTP retry mechanism.

  • Support a new lightweight mechanism for KFP pods to pull the run state they triggered. Default behavior is legacy, which pulls the logs of the run to figure out the run state. The new behavior can be enabled using a feature flag configured in the API.

Breaking changes#

  • Feature store: Ingestion using pandas now takes the dataframe and creates indices out of the entity column (and removes it as a column in this df). This could cause breakage for existing custom steps when using a pandas engine.

Closed issues#

  • Support logging artifacts larger than 5GB to V3IO. View in Git.

  • Limit KFP to kfp~=1.8.0, <1.8.14 due to non-backwards changes done in 1.8.14 for ParallelFor, which isn’t compatible with the MLRun managed KFP server (1.8.1). View in Git.

  • Add artifact_path enrichment from project artifact_path. Previously, the parameter wasn’t applied to project runs when defining project.artifact_path. View in Git.

  • Align timeouts for requests that are getting re-routed from worker to chief (for projects/background related endpoints). View in Git.

  • Fix legacy artifacts load when loading a project. Fixed corner cases when legacy artifacts were saved to yaml and loaded back into the system using load_project(). View in Git.

  • Fix artifact latest tag enrichment to happen also when user defined a specific tag. View in Git.

  • Fix zip source extraction during function build. View in Git.

  • Fix Docker compose deployment so Nuclio is configured properly with a platformConfig file that sets proper mounts and network configuration for Nuclio functions, meaning that they run in the same network as MLRun. View in Git.

  • Workaround for background tasks getting cancelled prematurely, due to the current FastAPI version that has a bug in the starlette package it uses. The bug caused the task to get cancelled if the client’s HTTP connection was closed before the task was done. View in Git.

  • Fix run fails after deploying function without defined image. View in Git.

  • Fix scheduled jobs failed on GKE with resource quota error. View in Git.

  • Can now delete a model via tag. View in Git.
