We're introducing some API changes for Train, Tune, and Data (Ray AIR) in the upcoming 2.7 release.

I've linked below the tentative API migration guide for the upcoming 2.7 release.

Changes include:

General AIR namespace

• Trainer: storage_path is required for distributed training/tuning
• Trainer API simplification

Preprocessors

• DatasetConfig → DataConfig
• Using Preprocessors with Trainers (to be approved?)

Checkpoints and Prediction

• Checkpoint: New API
• Removing BatchPredictor
• De-emphasize / Deprecate Checkpoint and deemphasize Predictor
• Removing PredictorDeployment
