# Model configuration

The YAML file next to the RKNN model is part of the deployment contract.

- `task` selects the task backend.
- `model` is relative to the YAML directory.
- `input` records width, height, layout, format and normalization.
- `postprocess` records adapter and thresholds.
- `labels_file` is relative to the YAML directory when present.

Do not replace only the `.rknn` file. Replace the model and YAML contract as a
unit, and regenerate `manifest.json` when any packaged file changes.
