…ation 171: Add ext7672-8241 stubs across 35 sklearn modules (+19,950 files) Run: https://github.com/githubnext/tsikit-learn/actions/runs/28448046366 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Evergreen — Merge AttemptEvergreen attempted to bring this PR up to date with its base branch ( The local merge completed cleanly, but the resulting patch contains ~519,000 file changes — far exceeding the capacity of the automated push tooling. A manual To fix manually: git fetch origin autoloop/build-tsikit-learn-scikit-learn-typescript-migration
git checkout autoloop/build-tsikit-learn-scikit-learn-typescript-migration-review-1782826745383
git merge origin/autoloop/build-tsikit-learn-scikit-learn-typescript-migration --no-edit
git push origin autoloop/build-tsikit-learn-scikit-learn-typescript-migration-review-1782826745383The failing CI checks (Lint, Test, Build Playground) may also be resolved once the branch is up to date with the fixes applied in the base branch.
