MobileTransformers — build artifacts
This is not a dataset. It is the set of build inputs that cannot live in git, published here so
that a git clone of
MobileTransformers can provision itself.
Nothing here is downloaded by the Android app or by any model package. These files are consumed by one script, at development time:
scripts/fetch_native_deps.sh # the natives bundle — required to build the Android SDK
TRAINING=1 scripts/fetch_native_deps.sh # + the ORT-training wheel, for exporting a training stage
SYMBOLS=1 scripts/fetch_native_deps.sh # + unstripped binaries, for symbolicating a native crash
That script reads third_party/android/manifest.json, downloads what is missing, checks the archive
sha256, unpacks it, and then checks every unpacked file's sha256 individually. Both halves matter: the
archive hash proves the download, the per-file hashes prove the unpack, and a half-populated
jniLibs/ is the failure mode that produces a linker error naming a symbol rather than a file.
Contents
| file | size | needed for |
|---|---|---|
mobiletransformers-natives-0.2.0-arm64-v8a.tar.zst |
63 MB | Required to build the Android SDK: ONNX Runtime (training build), the GenAI engine, the tokenizer static libs, and vendored headers. |
onnxruntime_training-1.23.0+cpu-cp312-cp312-linux_x86_64.whl |
632 MB | Only to export a training stage. Source-built, cp312/linux_x86_64 only — it is not on PyPI. |
mobiletransformers-natives-0.2.0-arm64-v8a-debug-symbols.tar.zst |
261 MB | Optional. The unstripped originals of the shipped .so files. Android's build strips them at packaging, so these cost nothing at runtime and are the only way to read a native stack trace. |
Every sha256, size, provenance and role is recorded in
third_party/android/manifest.json
and
third_party/onnxruntime/manifest.json.
Verify by hand with sha256sum if you prefer; the fetch script does it for you either way.
Licensing
These are builds of third-party projects — ONNX Runtime, onnxruntime-genai, tokenizers-cpp, protobuf
— each under its own upstream licence. See
THIRD_PARTY_NOTICES.md.
The license: other tag above reflects that this repo is a mixed bundle of upstream artifacts rather
than a single licensed work.
arm64-v8a only
There is no x86_64 build, so the SDK does not run on a standard Android emulator. libonnxruntime.so
and the tokenizer archives were never built for it; restoring x86_64 means building ONNX Runtime
Training and tokenizers-cpp for that ABI first.
