May 15, 2026 11:27 AM UTC

Version 1.4.1 of the relationalai Python package is now available!

To upgrade, activate your virtual environment and run the following command:

pip install --upgrade relationalai

New Features and Enhancements

• Added a new predictive reasoning API under relationalai.semantics.reasoners.predictive. It includes GNN for training, loading, registering, and predicting with Graph Neural Networks.

• rai init now gives clearer step-by-step terminal guidance. New config templates also default to browser-based Snowflake authentication instead of password placeholders. For interactive Snowflake sign-in, see Configure external browser authentication.

Bug Fixes

• Fixed prescriptive aggregate correctness bugs when defining a Problem.

• Fixed a recursion error caused by some expressions like model.where(count(B) >= 0).define(C.new(val=B)).

• rai reasoners:list and the interactive reasoner picker no longer fail if the backend returns unknown reasoner types.

• Problem.solve() now sends numeric type metadata to the solver service. This prevents float-valued MiniZinc solves from falling back to an integer-only path and failing with inexact conversion errors.
