I must say I dislike the hack around reading models (copying from assets to fs).

We expect most production apps to download models at runtime, so reading from the filesystem should be more natural in that case.  However, you’re right that it feels hacky when you’re first developing with the model as an asset.  We would accept a PR that added reading the model directly from the APK.

I hit a bug with some arm32 ops.

Please let us know what you find.  Or, if you are comfortable sharing the model, we can debug as well.
