lucascs@proton.me Lucas C.S. Prebuilt release of ONNX Runtime, Microsoft's cross-platform machine learning inference and training accelerator. Installs the upstream CPU-provider shared libraries (libonnxruntime.so and libonnxruntime_providers_shared.so) plus the C/C++ headers, taken straight from the official GitHub release tarball. Use this when building sci-libs/onnxruntime from source is impractical. The from-source package is preferred where possible: it links against system abseil-cpp, protobuf, re2 and onnx, and it can build the Python bindings, which this binary distribution does not ship. Upstream publishes separate tarballs for x86_64 (linux-x64) and AArch64 (linux-aarch64); SRC_URI selects between them by keyword. Both were confirmed present and byte-identical in layout for 1.27.1. https://github.com/microsoft/onnxruntime/issues https://onnxruntime.ai/docs/ microsoft/onnxruntime
