torchnep-publish.yml

name: Publish TorchNEP to PyPI

# Publishes the torchnep/ package to PyPI. Triggered by pushing a tag of the
# form `torchnep-vX.Y.Z` (a dedicated prefix so it never clashes with GPUMD's
# own version tags). The published version comes from torchnep/__init__.py
# (__version__) — bump it before tagging. `workflow_dispatch` allows a manual,
# non-publishing build for verification (publish step is skipped unless tagged).
