IMPORTANT: This release paves the way towards a breaking update of OpenML-Python. From version 0.15, functions that had the option to return a pandas DataFrame will return a pandas DataFrame by default. This version (0.14) emits a warning if you still use the old access functionality.

More concretely:

  • In 0.15 we will drop the ability to return dictionaries in listing calls and only provide pandas DataFrames. To disable warnings in 0.14 you have to request a pandas DataFrame (using output_format="dataframe").
  • In 0.15 we will drop the ability to return datasets as numpy arrays and only provide pandas DataFrames. To disable warnings in 0.14 you have to request a pandas DataFrame (using dataset_format="dataframe").

Furthermore, from version 0.15, OpenML-Python will no longer download datasets and dataset metadata by default. This version (0.14) emits a warning if you don't explicitly specify the desired behavior.

Please see the pull requests #1258 and #1260 for further information.
