# exceptions

Python API: `modelconverter.utils.exceptions`

Exception types raised by ModelConverter.

Everything the converter itself considers a failure of the conversion derives from
[ModelconverterException](https://docs.luxonis.com/software-v3/ai-inference/conversion/rvc-conversion/offline/modelconverter/modelconverter-api-reference/utils/exceptions.md),
which the CLI catches to exit with status 1, as opposed to the status 2 it uses for an unexpected error. The module also holds
[exit_with](https://docs.luxonis.com/software-v3/ai-inference/conversion/rvc-conversion/offline/modelconverter/modelconverter-api-reference/utils/exceptions.md),
the helper used where an error is fatal enough to end the process on the spot.
