# Wheel-only on PyPI; upstream pins requires_python = "<3.14,>=3.11".
# Optional AMD-quark quantization tool — vllm's rocm path can use it but
# does not depend on it, and nothing else in the tree RDEPENDs on it.
#
# onnx floor relaxed: upstream 0.12 requires onnx>=1.21.0,<=1.22.0, but
# ::gentoo tops out at onnx-1.20.1, so RDEPEND floors at 1.20.1 (the
# highest available; the `>=` self-heals to upstream's range once
# onnx-1.21+ lands). Safe here because the ONNX code paths are already
# non-functional: onnxscript and onnxslim (install-time deps of the
# wheel) are unpackaged in ::gentoo + ::guru, so anything touching ONNX
# export ImportErrors regardless — the PyTorch-only quantization paths
# this tool is used for don't import onnx. (Upstream 0.12 also dropped
# the old numpy<=2.1.3 cap → numpy>=2.0, which our unpinned numpy meets;
# new psutil dep added.) verified 2026-07-18
