Error message

Learning module not initialized

What it means

Guard in train: the lazily loaded LearningModule (_module) must exist before training on trajectories; the error fires when train is called before successful initialization or after destroy() nulled the module.

Solutions

1. Ensure the module/bridge/plugin initialize() method has been called and awaited before invoking this operation.
2. Guard against calls made during startup: await the initialization promise or check the initialized flag and fail fast with a clear setup hint.
