fast-sam
This repository hosts the fast-sam models exported for the
React Native ExecuTorch
library as ExecuTorch .pte programs, ready to run on device.
Upstream model: FastSAM

XNNPACK int8
The xnnpack/*_int8.pte files are static int8 (PT2E, per-channel weights) with the
first convolution and the Segment head kept fp32, except the mask prototype branch.
Class-agnostic COCO AR@100 on the first 500 val2017 images (all categories merged,
box NMS at IoU 0.9 as in the library):
| box AR@100 | mask AR@100 | |
|---|---|---|
| s fp32 | 41.65 | 36.25 |
| s int8 | 41.81 | 36.13 |
| x fp32 | 46.07 | 40.93 |
| x int8 | 46.09 | 41.04 |
Unshipped backends
A backend directory carrying a NOTES.md and no .pte was exported and
not published. Its note records what went wrong.

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.
To load these files in your own ExecuTorch runtime, read the compatibility note first.
