feat(experimentalist): wire up nemo-evaluator-sdk using HarborRunner by ngoncharenko · Pull Request #955 · NVIDIA-NeMo/nemo-platform

ngoncharenko · 2026-07-28T20:21:57Z

Summary

Add the NeMo Evaluator SDK-backed Harbor evaluator alongside the existing native Harbor evaluator.
Keep harbor_native as the implicit default; keep harbor as a deprecated alias and require harbor_evaluator for the SDK-backed path.
Share input resolution and job-directory result adaptation so both evaluator paths preserve the Experimentalist TrialResult and EvaluationResult contracts.
Align Eval Author with the same canonical evaluator default.

PR stack

Base/cache: feat(evaluator-sdk): skip re-execution if trial is present #1040 — evaluator SDK cache identity, partial resume, and stable scoped imports.
This PR: Experimentalist integration code and tests only.
Docs/examples: feat(experimentalist): add Harbor examples #1050 — reviewer guides and fast Harbor smoke coverage (stacked on this PR).

Review pointers

components/evaluator/harbor_evaluator.py — SDK-backed evaluator and runtime-config mapping.
components/evaluator/harbor.py — native evaluator plus the shared input/result boundaries.
components/evaluator/factory.py, deps.py, and base.py — evaluator selection and shared contracts.
test_evaluator_harbor_evaluator.py — mapping, execution, cache delegation, and result parity coverage.

Compatibility

Both evaluator types still run Harbor. The change is orchestration ownership: harbor_native builds and runs Harbor directly, while harbor_evaluator delegates the job to HarborAgentTaskRunner. Unsupported native-only options are rejected rather than ignored. The default remains harbor_native until the SDK-backed path reaches full parity and completes UAT.

Shared entry and exit

Both evaluator paths use the same resolved inputs before orchestration and the same job-directory adapter afterward:

                    resolve_harbor_run_inputs()     ← ENTRY (shared)
                              │

     (plugin builds Job)              (SDK builds Job)
              │                               │
              └───────────────┬───────────────┘
                              ▼
                    trials_from_job_dir()           ← EXIT (shared)
                              │
                              ▼
                    TrialResult[] for the loop

Sharing resolve_harbor_run_inputs() makes both paths agree on agent path, dataset path, job directory, and preflight before either starts Harbor. Sharing trials_from_job_dir() keeps the optimizer-facing trial contract identical regardless of which path owns orchestration.

Harbor evaluator architecture

Layer / File(s)	Summary
Evaluator contracts and shared Harbor adapters `plugins/nemo-experimentalist/src/nemo_experimentalist_plugin/experimentalist/components/evaluator/{base.py,factory.py,harbor.py}`, `plugins/nemo-experimentalist/src/nemo_experimentalist_plugin/config.py`	Adds canonical evaluator types, deprecated-value normalization, completed-trial aggregation, typed dispatch, and shared Harbor input/result handling.
Native Harbor evaluator `plugins/nemo-experimentalist/src/nemo_experimentalist_plugin/experimentalist/components/evaluator/harbor_native.py`, `plugins/nemo-experimentalist/tests/experimentalist/test_evaluator_harbor.py`	Moves native Harbor execution into its own module and preserves scoped imports, trace artifacts, job execution, cleanup, and result conversion.
SDK-backed Harbor evaluator `plugins/nemo-experimentalist/src/nemo_experimentalist_plugin/experimentalist/components/evaluator/harbor_evaluator.py`, `plugins/nemo-experimentalist/tests/experimentalist/{conftest.py,test_evaluator_harbor_evaluator.py}`, `plugins/nemo-experimentalist/pyproject.toml`	Adds the NeMo Evaluator SDK runner, strict options, task-name mapping, cache behavior, trace handling, and parity tests.

Merge Risk: 🟡 Moderate · up to 14066

The PR adds an SDK-backed Harbor evaluator while preserving the native evaluator as the default and sharing result adaptation. A malformed trial result can still abort processing for the entire job without identifying the failing path, so merge is not fully ready until that bounded failure mode is fixed or explicitly accepted; the typing cleanup is non-blocking.

TYPE_CHECKING-only import violates path guideline.

HarborAgentTaskRunner, HarborRuntimeConfig, AgentEvalTask are imported only under TYPE_CHECKING for annotation purposes. The lazy-import rationale (documented in the module docstring) is sound, but this specific pattern is exactly what the path guideline prohibits. Consider a structural Protocol for the SDK surface actually used (mirroring HarborJobOptions in harbor.py), which preserves the lazy-import contract without a TYPE_CHECKING-only import.

As per path instructions, plugins/nemo-experimentalist/**/*.py: "Use concrete type hints rather than string-based type hints, and do not hide imports under TYPE_CHECKING."

In `@plugins/nemo-experimentalist/docs/architecture.md`:
- Around line 308-309: Update the failed-trial aggregation statement in the
architecture documentation to accurately describe the evaluator contract: failed
trials are excluded from the mean, so they do not directly lower it but reduce
the number of contributing trials. Remove the contradictory claim that a crash
drags the aggregate down.
- Around line 690-700: Make the evaluator example runnable by importing Path,
defining an async main function, and invoking it through asyncio.run(main())
instead of awaiting at module scope. Before evaluator.run, materialize the
baseline agent using the same approach as docs/e2e/run-eval-only.py so the
referenced agent-0 path exists.

…ions Round-2 review fixes on #955. Verifier (all 5 copies of tests/test.sh): - Normalize CRLF at end-of-line only. `tr -d '\r'` deleted every carriage return, so `sum=4<CR>2` collapsed into a passing `sum=42` — the same reward-hacking class as the trailing-output hole fixed earlier. The agent under test is code the optimizer actively reward-maximizes, so a lax verifier is a live surface, not a hypothetical one. - Mirror the rule in test_hello_example_baseline.py, which had the identical hole via `.replace("\r", "")`, and assert the shell and Python rules stay in lockstep; that pairing has now drifted twice. Docs: - Give every evaluator arm its own --experiment-dir. README.md (plain Harbor) and docs/e2e/README.md (SDK runner) both pointed at tmp/exp-hello-eval; the two evaluators disagree about an existing job dir, so sharing one makes the result order-dependent. - Point the --force-rerun example at tmp/eval-only-sdk rather than the default.

TYPE_CHECKING-only SDK imports conflict with the repo guideline.

The docstring rationale is sound (a broken SDK install must not break the plain evaluator), so this is likely the right call — but it deviates from the stated rule. Consider annotating with NamedTuple field types resolved via Any/protocols, or documenting the exemption so the next reader doesn't "fix" it.

As per coding guidelines: "prefer concrete type hints over string-based type hints, and do not import those types only under TYPE_CHECKING; import them normally when possible."

Use _safe_resolve here too.

Path.resolve() on a vanishing symlink chain can raise OSError (the reason _safe_resolve exists). Lines 489/500 and 588 call .resolve() directly, so a mid-walk race turns a best-effort cache check into a failed run.

I've got some questions around using AgentEvaluator and duplication of models in the plugin.

Three findings from CodeRabbit on PR #955. * Scoped agent import: `_install_agent_package` wrote `__path__` unconditionally, so a second scope sharing a package name silently repointed the first, still-open scope at a different directory. Keep the first path instead. CodeRabbit proposed hashing the resolved directory path into the package identity. Rejected: that makes the name location-dependent, so the same agent evaluated from a different path yields a different JobConfig and Harbor refuses to resume -- reintroducing AALGO-430, which this branch exists to fix. A shared package name implies an equal content digest, hence byte-identical trees (the excluded content is not importable), so the already-installed path is exactly as correct and keeping it is the safe resolution. * Resume e2e: deleting the only trial result made "discarded and re-run from scratch" observationally identical to "resumed", so the test passed either way. Now runs two attempts, drops one, and asserts the surviving trial directory keeps its name and its result.json byte-for-byte -- Harbor suffixes trial dirs with a shortuuid, so a discarded job dir returns under a different name. Verified by mutation: forcing force_rerun=True now fails the test. * architecture.md no longer promises `harbor` as an SDK-unavailable fallback -- false since the SDK import moved to module scope. CodeRabbit flagged one paragraph; the adjacent "import optional runtimes lazily inside `_run`" guidance was wrong for the same reason and is corrected too. Uses `harbor_native` per the rename, with `harbor` named only as the deprecated alias. Refs AALGO-430, AALGO-312.

before stamp computed even when caching is disabled.

before = _cache_stamp(self._config, dataset_path, coverage) (and the coverage walk feeding it) runs unconditionally whenever a native job is (re)built — including when self._config.job_name is None. Only the after comparison/write is gated on job_name is not None (line 309). This directly contradicts the stated intent a few lines above ("This keeps the digest I/O off every run of callers that don't pin a job name") — every unpinned run now pays for a full agent/dataset content digest with no use for the result.

based on our convo in standup the approach is:

keep the existing experimentalist models; mark them deprecated (or somehow signal that we should be informed if changes are being made)
merge this and close any feature gaps with the harbor runner
perform UAT testing with the experimentalist team
cut over to the new evaluator-harbor runner
migrate experimentalist to the evaluator models

Add the trial path to a result.json parse failure.

A truncated or partial result.json raises a bare json.JSONDecodeError. The message names no file, and one bad trial aborts the whole job adaptation. Attach the path so the failing trial is identifiable.

Add a Field description.

Every other option in this model carries a description, and this value is recorded in config_snapshot. State the accepted values and that harbor is deprecated.

The default matches the retained arm. Based on learnings: treat harbor_native as the intentional default evaluator until harbor_evaluator reaches functional parity, and keep the harbor alias deprecated.

Restore _warned_evaluator_types after the test.

PlainJob shares _FakeJob.calls.

PlainJob does not define its own calls, so cls.calls.append(config) in create writes into _FakeJob.calls. Both evaluator runs accumulate into one list. This test never asserts on calls, so it passes today, but the shared list is a trap for the next assertion added here.
