2.1 Release

2.1 Release

Description

This is a mainly maintenance release introducing a few new features.

New in this release

• Decorators for transformers and operators
  • Regular def foo(...): can now be converted to transformers or operators via decorators. e.g for a numpy transformer: @kosh.numpy_transformer. See the transformer and operators notebooks for more details.
• Introducing a loader for text and column-based data, based on top numpy.loadtxt. See this notebook.
• When cloning a dataset one can choose to preserve ensemble memberships (preserve_ensembles_memberships=True), simply copy over these attributes (preserve_ensembles_memberships=False) (default) or ignore information related to ensembles (preserve_ensembles_memberships=-1)
• Dataset objects now have a is_ensemble_attribute() function to know if an attribute belongs to an ensemble.
• Added list_attributes() function to ensemble objects.

Improvements

• When printing a dataset, the attributes coming from ensembles the dataset belongs to are listed in a separate section.

Bug fixes

• When cloning a dataset, an artificial id attribute was created with the original dataset id in it.
• Setting an attribute to an invalid value would cause the dataset to disappear from the store.
