PyTorch-style wheel index for the fastfields Python packages. Pick the folder matching your compute backend and pass it as an --extra-index-url (dependencies still resolve from PyPI):
These backends are declared but have no wheels published yet, so no packages are served under them at all — passing one as an --extra-index-url resolves to nothing and your install silently falls back to PyPI. Do not use them until a build lands here.
See the repository for how the index is built.
