Installation

QECTOR Decoder v3 ships as a Rust-compiled Python wheel for Python 3.9–3.13 on Linux x86_64 (manylinux_2_17), macOS 11.0+ (arm64), and Windows amd64: 15 binary wheels, no sdist.

pip install qector-decoder-v3==1.0.0

# Optional extras
pip install "qector-decoder-v3[stim]"   # Stim / Sinter / PyMatching / LDPC ecosystem
pip install "qector-decoder-v3[bench]"  # Benchmark harness
pip install "qector-decoder-v3[all]"    # Full environment

# Verify

python -c "import qector_decoder_v3 as qd; print(qd.__version__)"

• Linux: manylinux_2_17 x86_64 wheels (Ubuntu 20.04+, Debian 11+, RHEL 8+).
• macOS: arm64 wheels, macOS 11.0+.
• Windows: amd64 wheels, Python 3.9–3.13.
• CUDA batch path ships in every wheel; OpenCL kernels require a source build (opencl_is_available() is False on wheels by design).
