# types

Python API: `hubai_sdk.utils.types`

Enums used by model metadata and conversion configuration.

Service APIs generally accept these enums directly. Their `value` is the spelling sent to HubAI, while `name` is used by a few
list filters. Use [Target](https://docs.luxonis.com/cloud/hubai/model-registry/hubai-sdk/hubai-sdk-api-reference/utils/types.md)
to choose conversion hardware and
[ModelType](https://docs.luxonis.com/cloud/hubai/model-registry/hubai-sdk/hubai-sdk-api-reference/utils/types.md) to describe an
existing artifact.
