[review] [Autoloop: build-tsikit-learn-scikit-learn-typescript-migration] - #25
Conversation
…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.

Evergreen attempted to merge the base branch — unable to push due to patch size. The PR head branch is 128 commits behind Why so large? The base autoloop branch contains ~19,950+ generated stub files added across many iterations.

Evergreen attempted to fix: behind base branch by 128 commits I merged This PR cannot be automatically rebased/merged by Evergreen in its current state. The base branch has accumulated nearly 1 million generated stub files which makes the diff too large to push incrementally.
