cuda.core: fix invalid python_version target in pixi.toml#2029
Merged
Conversation
Pixi's [package.target.<X>] only accepts platform identifiers; the
'python_version < "3.11"' selector caused every pixi invocation against
cuda_core/pixi.toml to fail at manifest-parse time
('python_version < "3.11"' is not a known platform).
Move backports.strenum into [package.run-dependencies] unconditionally
and let conda-forge's per-Python variants (real impl on <3.11, no-op
stub on >=3.12) handle version selection. Lockfile regenerated.

There was a problem hiding this comment.
Seems fine for pixi. Wouldn't want to ship this metadata in any package we ship, but fine for local use.

Summary
cuda_core/pixi.tomlhad[package.target.'python_version < "3.11"'.run-dependencies], but pixi only accepts platform identifiers in[package.target.<X>]. Everypixi runagainst this manifest failed at parse time:backports.strenuminto the unconditional[package.run-dependencies]. Conda-forge ships per-Python variants (real impl gated topython <3.11, plus a 1.3.1 stub gated topython >=3.12), so the solver picks the right build perworkspace.build-variantsPython (3.10–3.14).backports.strenum-1.3.1now appears in the relevant environments.Why this slipped in
No CI workflow currently runs
pixi, so the broken stanza was never validated. Worth a follow-up to add apixi task listsmoke check, but out of scope here.Test plan
