QNN variants

A QNN .pte embeds an HTP context binary compiled for one Hexagon version, so there is one file per version and the runtime picks the one matching the device. These return a class index per pixel, (1, 520, 520) int32, rather than (1, 21, 520, 520) logits.

Hexagon	Example SoC
v69	Snapdragon 8 Gen 1
v73	Snapdragon 8 Gen 2
v75	Snapdragon 8 Gen 3
v79	Snapdragon 8 Elite
v81	Snapdragon 8 Elite Gen 5

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.
