• v0.16.6 Changes

  October 23, 2020

  Major features and improvements

  • ➕ Added documentation with a focus on single machine and distributed environment deployment; the series includes Docker, Argo, Prefect, Kubeflow, AWS Batch, AWS Sagemaker and extends our section on Databricks
  • ➕ Added kedro-starter-spaceflights alias for generating a project: kedro new --starter spaceflights.

  🐛 Bug fixes and other changes

  • 🛠 Fixed TypeError when converting dict inputs to a node made from a wrapped partial function.
  • PartitionedDataSet improvements:
    • Supported passing arguments to the underlying filesystem.
  • 👌 Improved handling of non-ASCII word characters in dataset names.
    • For example, a dataset named jalapeño will be accessible as DataCatalog.datasets.jalapeño rather than DataCatalog.datasets.jalape__o.
  • 🛠 Fixed kedro install for an Anaconda environment defined in environment.yml.
  • 🛠 Fixed backwards compatibility with templates generated with older Kedro versions <0.16.5. No longer need to update .kedro.yml to use kedro lint and kedro jupyter notebook convert.
  • 👌 Improved documentation.
  • ➕ Added documentation using MinIO with Kedro.
  • 👌 Improved error messages for incorrect parameters passed into a node.
  • 🛠 Fixed issue with saving a TensorFlowModelDataset in the HDF5 format with versioning enabled.
  • Added missing run_result argument in after_pipeline_run Hooks spec.
  • 🛠 Fixed a bug in IPython script that was causing context hooks to be registered twice. To apply this fix to a project generated with an older Kedro version, apply the same changes made in this PR to your 00-kedro-init.py file.

  Migration guide from Kedro 0.16.1 to 0.16.2

  Guide to apply the fix for %run_viz line magic in existing project

  0️⃣ Even though this release ships a fix for project generated with kedro==0.16.2, after upgrading, you will still need to make a change in your existing project if it was generated with kedro>=0.16.0,<=0.16.1 for the fix to take effect. Specifically, please change the content of your project's IPython init script located at .ipython/profile_default/startup/00-kedro-init.py with the content of this file. You will also need kedro-viz>=3.3.1.

  💥 Breaking changes to the API

  Datasets

  • ✂ Deleted obsolete datasets from kedro.io.
  • ✂ Deleted kedro.contrib and extras folders.
  • ✂ Deleted obsolete CSVBlobDataSet and JSONBlobDataSet dataset types.
  • Made invalidate_cache method on datasets private.
  • get_last_load_version and get_last_save_version methods are no longer available on AbstractDataSet.
  • get_last_load_version and get_last_save_version have been renamed to resolve_load_version and resolve_save_version on AbstractVersionedDataSet, the results of which are cached.
  • 🚀 The release() method on datasets extending AbstractVersionedDataSet clears the cached load and save version. All custom datasets must call super()._release() inside _release().
  • TextDataSet no longer has load_args and save_args. These can instead be specified under open_args_load or open_args_save in fs_args.
  • PartitionedDataSet and IncrementalDataSet method invalidate_cache was made private: _invalidate_caches.

  Other

  • Removed KEDRO_ENV_VAR from kedro.context to speed up the CLI run time.
  • 🚚 Pipeline.name has been removed in favour of Pipeline.tag().
  • ⬇️ Dropped Pipeline.transform() in favour of kedro.pipeline.modular_pipeline.pipeline() helper function.
  • 🚚 Made constant PARAMETER_KEYWORDS private, and moved it from kedro.pipeline.pipeline to kedro.pipeline.modular_pipeline.
  • 🚚 Layers are no longer part of the dataset object, as they've moved to the DataCatalog.
  • 👍 Python 3.5 is no longer supported by the current and all future versions of Kedro.

  🚀 Migration guide from Kedro 0.15.* to Upcoming Release

  Migration for datasets

  ⚡️ Since all the datasets (from kedro.io and kedro.contrib.io) were moved to kedro/extras/datasets you must update the type of all datasets in <project>/conf/base/catalog.yml file.
  Here how it should be changed: type: <SomeDataSet> -> type: <subfolder of kedro/extras/datasets>.<SomeDataSet> (e.g. type: CSVDataSet -> type: pandas.CSVDataSet).

  🗄 In addition, all the specific datasets like CSVLocalDataSet, CSVS3DataSet etc. were deprecated. Instead, you must use generalized datasets like CSVDataSet.
  E.g. type: CSVS3DataSet -> type: pandas.CSVDataSet.

  Note: No changes required if you are using your custom dataset.

  Migration for Pipeline.transform()

  Pipeline.transform() has been dropped in favour of the pipeline() constructor. The following changes apply:

  • Remember to import from kedro.pipeline import pipeline
  • The prefix argument has been renamed to namespace
  • And datasets has been broken down into more granular arguments:
    • inputs: Independent inputs to the pipeline
    • outputs: Any output created in the pipeline, whether an intermediary dataset or a leaf output
    • parameters: params:... or parameters

  As an example, code that used to look like this with the Pipeline.transform() constructor:

  result = my\_pipeline.transform( datasets={"input": "new\_input", "output": "new\_output", "params:x": "params:y"}, prefix="pre")
  

  When used with the new pipeline() constructor, becomes:

  from kedro.pipeline import pipelineresult = pipeline( my\_pipeline, inputs={"input": "new\_input"}, outputs={"output": "new\_output"}, parameters={"params:x": "params:y"}, namespace="pre")
  

  Migration for decorators, color logger, transformers etc.

  ⚡️ Since some modules were moved to other locations you need to update import paths appropriately.
  🚀 You can find the list of moved files in the 0.15.6 release notes under the section titled Files with a new location.

  Migration for KEDRO_ENV_VAR, the environment variable

  ⚡️ > Note: If you haven't made significant changes to your kedro_cli.py, it may be easier to simply copy the updated kedro_cli.py .ipython/profile_default/startup/00-kedro-init.py and from GitHub or a newly generated project into your old project.

  • We've removed KEDRO_ENV_VAR from kedro.context. To get your existing project template working, you'll need to remove all instances of KEDRO_ENV_VAR from your project template:
    • From the imports in kedro_cli.py and .ipython/profile_default/startup/00-kedro-init.py: from kedro.context import KEDRO_ENV_VAR, load_context -> from kedro.framework.context import load_context
    • Remove the envvar=KEDRO_ENV_VAR line from the click options in run, jupyter_notebook and jupyter_lab in kedro_cli.py
    • Replace KEDRO_ENV_VAR with "KEDRO_ENV" in _build_jupyter_env
    • Replace context = load_context(path, env=os.getenv(KEDRO_ENV_VAR)) with context = load_context(path) in .ipython/profile_default/startup/00-kedro-init.py

  🏗 Migration for kedro build-reqs

  📚 We have upgraded pip-tools which is used by kedro build-reqs to 5.x. This pip-tools version requires pip>=20.0. To upgrade pip, please refer to their documentation.
