v1.12.0

This release adds support for Python 3.12! It also adds a number of feature improvements. It adds a simplify_schema utility function to the sdv.utils.poc module which simplifies multi-table schemas so they can be run using HMASynthesizer. Multi-table data dictionaries can now be saved directly to CSVs using the sdv.datasets.local.save_csvs utility function. Additionally, generator-discriminator loss values can now be plotted directly from CTGAN using the get_loss_values_plot method. This release also adds error messages when trying to load an SDV synthesizer on an older version of the SDV, or when trying to re-fit a synthesizer from an older version of the SDV.

This release also fixes a number of bugs. Metadata auto-detection now validates that all primary keys are unique, and the metadata correctly validates sdtypes in a column relationship. Bugs in the HMASynthesizer that would cause the diagnostic score to not be equal to 1.0 for cardinality and data validity were fixed. Finally, errors in constraints now correctly raise a ConstraintsNotMetError instead of an InvalidData error.

Internal

Bugs Fixed

  • Metadata isn't validating sdtypes in a column relationship (public SDV only) - Issue #1781 by @R-Palazzo
  • Contextual Anonymization transformers shouldn't be used for primary keys - Issue #1807 by @fealho
  • HMASynthesizer diagnostic score is not 1.0 when using 'truncnorm' distribution - Issue #1831 by @frances-h
  • InvalidDataError: The provided data does not match the metadata (although it matches) - Issue #1833 by @pvk-developer
  • HMA likelihood match should respect cardinality - Issue #1834 by @fealho
  • When inappropriately applying ScalarRange constraint, InvalidDataError is being returned instead of ConstraintsNotMetError - Issue #1842 by @pvk-developer

  • Error in Setting IDGenerator for Primary Key columns - Issue #1862 by @lajohn4747
  • Metadata auto-detection should ensure primary keys are unique (special sdtypes are not exempt from this rule!) - Issue #1871 by @R-Palazzo
