# utils

Python API: `luxonis_train.utils`

Helpers shared across the package.

The package re-exports the main helpers of its modules. They cover the bounding box and keypoint maths, the conversion of head
outputs to dataset records, the OCR encoder and decoder, the segmentation masks, the spatial transforms, the checkpoint filter,
the dataset metadata, the experiment tracker, the logging setup,
[IncompatibleError](https://docs.luxonis.com/software-v3/ai-inference/model-source/training/luxonis-train/luxonis-train-api-reference/utils/exceptions.md),
and general helpers for batches, signatures, and downloads.
