dcccpy-linux-runtime

dcccpy-linux-runtime carries the prebuilt Linux DCCCcore runtime used by dcccpy[linux-runtime].

This package is optional. The plain dcccpy package can download DCCCcore from GitHub releases on first use. Install this runtime package when a user or environment needs pip install to provide the native runtime without first-run download.

Before building this package, vendor the release asset:

python scripts/vendor_dccccore.py --version 4.4.0 --release-platform ubuntu-latest-x64
python -m build --wheel

For a PyPI-size runtime wheel, use the slim profile:

python scripts/vendor_dccccore.py --profile pypi-slim --force
python -m build --wheel

The pypi-slim profile omits the fast_and_acc registration model/config and the ADAD decoupler ONNX ensemble. It keeps the default spatial normalization model and the assets needed by common Centiloid/CenTauR/CenTauRz workflows.

The vendored runtime is intentionally ignored by git because it contains large ONNX model and NIfTI template assets.
