Installation

Python toolchain

Requires Python 3.10 or later.

pip install tigris-ml

This pulls in all Python dependencies automatically. pip picks a wheel for your platform:

Platform	Wheel	tigris run
Linux x86-64 and ARM64, glibc 2.28 or newer	native (manylinux_2_28)	yes
macOS 11 or newer, x86-64 and ARM64	native	yes
Windows x86-64	native	yes
musl Linux (Alpine), Windows ARM64, 32-bit ARM Linux, older glibc	pure Python	with your own host library

Native wheels bundle the portable C runtime as a host library, so tigris run can execute compiled plans on your machine. The pure Python wheel has every other command: analyze, compile, codegen, inspect and zoo. There run stops with “Bundled host runtime is unavailable” unless you build the host library from the runtime sources and set TIGRIS_HOST_LIBRARY to it; see Using your own host library. No native runtime is downloaded separately during installation or execution.

Development install

Clone the repo and install with dev extras for testing:

git clone https://github.com/raws-labs/tigris.git
cd tigris
pip install -e ".[dev]"

The [dev] extra adds pytest and onnxruntime (used for reference output validation).

Verify

tigris --version

This also prints the host runtime version and where it comes from, for example tigris, version X.Y.Z (runtime X.Y.Z; bundled), or (runtime unavailable) on the pure wheel without an override. Compiler and runtime release as a pair with the same version number; each plan still records its own schema, and each runtime states which plan schemas it accepts.

C runtime

The runtime is a self-contained C project built with CMake as C11. It has no external dependencies and needs no package manager. The portable harness that tigris codegen generates is C99.

git clone https://github.com/raws-labs/tigris-runtime.git
cd tigris-runtime
cmake -B build && cmake --build build

Run the self-contained test suite:

ctest --test-dir build --output-on-failure

Platform notes

Platform	Status	Notes
Linux (x86_64, aarch64)	Supported	Primary development platform
macOS (Apple Silicon, Intel)	Supported
Windows (x86-64)	Supported for the Python toolchain	The native wheel includes the host runtime. Building the C runtime for firmware from Windows is untested; WSL is recommended.
