| # 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](https://github.com/martinkorelic/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: |
|
|
| ```bash |
| 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`](https://github.com/martinkorelic/mobiletransformers/blob/main/third_party/android/manifest.json) |
| and |
| [`third_party/onnxruntime/manifest.json`](https://github.com/martinkorelic/mobiletransformers/blob/main/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`](https://github.com/martinkorelic/mobiletransformers/blob/main/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. |
