About

This issue bundles and describes two flaws with dependencies, which have been occurring at the same time, five days ago, but are independent from each other.

What's Inside

Enumerating the incompatibilities with recent releases in Python.

Joblib 1.4.0 incompatibility

PyCaret is incompatible with Joblib 1.4.0, because it uses a private function which is no longer there.

• [BUG]: Can't use RegressionExperiment with the latest version of joblib (1.4.0) #3959
• Fix dependency: Joblib 1.4.0 breaks PyCaret, so vendorize compatibility routines #3965
• Fix dependency: Joblib 1.4.0 breaks PyCaret, so downgrade to <1.4 #3967

Python 3.11.9 incompatibility

Previous versions of Dask, which is pulled in transitively via Fugue through pycaret[parallel], stopped working on Python 3.11.9, so that needs an update.

• Incompatibility with python 3.11.9 dask/dask#11038
• [BUG]: TypeError: descriptor '__call__' for 'type' objects doesn't apply to a 'property' object #3960
• Fix dependency: Python 3.11.9 breaks Dask #3963

Evaluation

It is advisable to release this update on behalf of a bugfix release, because otherwise, on new and fresh installations, pulling in Joblib 1.4.0, or when upgrading to Python 3.11.9 and newer, things will go south.

Trivia
