Bring your own model with Amazon SageMaker AI: Script mode in SDK v3

Amazon Web Services · 1 month ago · 39

Amazon SageMaker AI’s Python SDK v3 redesigned bring-your-own-model script mode by replacing framework-specific estimator and deployment classes with ModelTrainer for training and ModelBuilder for deployment. It syncs a local source_dir into the training container at runtime when the job starts (using SourceCode with command or entry_script), so the training and inference code can be changed without rebuilding Docker images. As a result, one API works across multiple frameworks, and developers can iterate faster while keeping full control over the container contents.
