The record

What it does: Lale is a Python library for semi-automated data science that helps select algorithms and tune pipeline hyperparameters.
Automation: It provides a consistent interface to pipeline search tools including Hyperopt, GridSearchCV, and SMAC.
Correctness checks: Lale uses JSON Schema to catch mismatches between hyperparameters and their types, or between data and operators.
Interoperability: It includes operators from libraries such as scikit-learn, XGBoost, and PyTorch.
Install and use: Lale installs as a Python package and can be used with tools such as Jupyter notebooks.
Operating systems: The installation guide says Lale can be used on Linux, Windows 10, or Mac OS X.
Modalities and tasks: The FAQ says Lale has been used for text, images, time series, and multimodal data, and for regression as well as classification.
Deep learning: Lale includes some deep-learning operators, but the FAQ says it does not currently support full-fledged neural architecture search.
Custom operators: Operators following scikit-learn fit/predict or fit/transform conventions can be wrapped for use with some Lale features.
IBM product relationship: Lale is free, open source, Apache-licensed, and does not require commercial IBM products; IBM's AutoAI SDK uses it.
Release status: The repository describes Lale as being in an Alpha release and says it comes without warranties.
Performance focus: The FAQ says computational performance has received some attention but has not been a major focus.
Purpose: Lale is a Python library for semi-automated data science that helps select algorithms and tune pipeline hyperparameters in a type-safe way.
Integrations: Its operator libraries include support based on scikit-learn, AI Fairness 360, category_encoders, imbalanced-learn, LightGBM, Snap ML, and XGBoost.
