| description | CI/CD reference for NeMo-RL. Covers GitHub Actions pipeline structure, CI triggering via /ok to test, and CI failure investigation. |
| when_to_use | Investigating a CI failure; understanding the pipeline structure; triggering CI; 'CI is red', 'how do I trigger CI', '/ok to test', 'PR workflow', 'where are the logs', 'CI did not run', 'copy-pr-bot'. |
NeMo-RL CI runs on GitHub Actions. Workflows live in .github/workflows/.
The main test workflow triggers on pushes to pull-request/<number> branches.
These branches are created automatically by copy-pr-bot when a contributor
pushes to their fork and the PR receives a trust signal:
/ok to test <full-sha> as a PR comment.After pushing a new commit to your PR, trigger CI with:
/ok to test <full-commit-sha>
Use git rev-parse HEAD (not the short form) to get the full SHA.
Re-triggering after new commits: each
/ok to test <sha>is specific to that SHA. After pushing additional commits, post a new comment with the updated SHA.
Every PR must have exactly one CI:* label — the quality-check job stays
red until one is attached. Labels control which test tier runs and whether a
new container image is built.
| Label | What runs | Container |
|---|---|---|
CI:docs | Doc tests only | Reuses main container |
CI:Lfast | Fast test subset | Reuses main container |
CI:L0 | Unit tests + docs + lint | Builds new image |
CI:L1 | L0 + functional tests | Builds new image |
CI:L2 | L1 + convergence tests | Builds new image |
Skip CICD | Nothing (skips all tests) | — |
Default on merge group / push to main: L1.
Which label to attach when opening a PR:
| Changed paths / nature of change | Label |
|---|---|
Docs only (docs/, *.md, docstrings) | CI:docs |
| Trivial fix, no logic change | CI:Lfast |
| New code, bug fix, refactor | CI:L0 |
| Changes that could affect model behaviour | CI:L1 |
| Changes that could affect convergence | CI:L2 |

Common failure patterns:
| Symptom | Likely cause | Fix |
|---|---|---|
| CI never starts | No trust signal or copy-pr-bot not triggered | Post /ok to test <sha> |
