# ssdlite320-mobilenet-v3-large

This repository hosts the **ssdlite320-mobilenet-v3-large** models exported for the
[React Native ExecuTorch](https://www.npmjs.com/package/react-native-executorch)
library as ExecuTorch `.pte` programs, ready to run on device.

Upstream model: [SSDLite320 MobilenetV3 Large](https://pytorch.org/vision/main/models/generated/torchvision.models.detection.ssdlite320_mobilenet_v3_large.html#ssdlite320-mobilenet-v3-large)

## Variants

| Path | Backend | Precision |
| --- | --- | --- |
| `coreml/ssdlite320_mobilenet_v3_large_coreml_fp16.pte` | coreml | fp16 |
| `xnnpack/ssdlite320_mobilenet_v3_large_xnnpack_fp32.pte` | xnnpack | fp32 |

## Unshipped backends

A backend directory carrying a `NOTES.md` and no `.pte` was exported and
not published. Its note records what went wrong.

- `mlx` ([why](https://huggingface.co/software-mansion/react-native-executorch-ssdlite320-mobilenet-v3-large/blob/main/mlx/NOTES.md))

## Compatibility

These files are published for the **ExecuTorch v1.4.1** runtime. ExecuTorch
gives no forward compatibility guarantee, so an older runtime may fail to load
them.

To use them in React Native ExecuTorch, pass the model constant shipped in the
library's model registry to the corresponding task pipeline. See the
[documentation](https://docs.swmansion.com/react-native-executorch/docs/fundamentals/downloading-models).

To load these files in your own ExecuTorch runtime, read the
[compatibility note](https://github.com/pytorch/executorch/blob/main/runtime/COMPATIBILITY.md)
first.
