feat(evaluator): submit a live Gym runner as an agent-evaluation job - #1367
Merged
Conversation
Contributor
|
An evaluation someone got working locally with `AgentEvaluator()` can now be
submitted as a governed job without retyping its configuration:
evaluator.submit(tasks=TasksetRef("default/my-suite"), target=gym_runner)
`runner_to_target` describes a live `GymAgentTaskRunner` as the `GymRunnerTarget`
that reproduces it job-side, and refuses runners carrying state the wire cannot
express rather than silently submitting something other than what was tested.
Only Gym is supported; the other runners each need their own decisions about what
survives translation and are deliberately not guessed at.
`submit()` gains a fourth overload discriminated by `tasks`, and agent jobs get
their own `AgentEvaluatorJobResource` / `AgentEvaluatorJob`. The resource is not
related to `EvaluatorJobResource` by inheritance in either direction: a row
evaluation publishes `aggregate-scores` and `row-scores`, an agent evaluation
publishes `agent-eval-results` and `summary`, so sharing a base would put
readers here whose type says "results" and whose behaviour is a 404.
Isolate the integration fixtures' entity store (`NMP_DATA_DIR`) alongside their
file storage. They already pointed file storage at a per-run temp dir but left
the database on the developer's real platform, which both wrote test entities
into a live local install and broke reruns: metric bundles are content-addressed,
so a second run found the first run's bundle entity, skipped the upload as a
duplicate, then failed to download a blob that went away with the old temp dir.

- Line 74: Update _gym_target to validate that the Gym configuration is
JSON-serializable before constructing GymRunnerTarget, converting invalid values
such as callables or arbitrary objects into UnsubmittableRunnerError rather than
allowing PydanticSerializationError from model_dump(mode="json") to escape. Add
a regression test covering a non-JSON hydra_params value.
In `@plugins/nemo-evaluator/src/nemo_evaluator/sdk/job_resources.py`:
- Around line 255-259: Update the route construction in the job resource
initializer using job_route_base_url so agent jobs resolve through
/agent-evaluate/jobs rather than the hardcoded /evaluate/jobs base, while
preserving the existing route behavior for other jobs. Add a status-route test
covering get_job_status or wait_until_done for an agent job and asserting the
/agent-evaluate/jobs/{name}/status path.
In `@plugins/nemo-evaluator/src/nemo_evaluator/sdk/resources.py`:
- Around line 175-187: Update the tasks branch in submit so it rejects config,
field_mapping, prompt_template, and metric_bundle_packager when tasks is
provided, alongside metric and dataset, before calling
_executor.submit_agent_eval. Add coverage verifying each option raises the
validation error and is not silently discarded.

Two review findings on #1367, both in error handling rather than the happy path. `submit(tasks=...)` accepted `config`, `field_mapping`, `prompt_template` and `metric_bundle_packager` and then dropped them: only `metric` and `dataset` were rejected. A caller supplying any of the four got a job that silently ignored it. All four are now refused, naming whichever were passed and pointing at `target` as what configures a taskset run. `_gym_target` promised in its docstring to refuse state with no wire form, but `hydra_params` and `env_vars` are typed loosely enough to hold a callable, which survived construction and failed later inside `model_dump(mode="json")` -- a `PydanticSerializationError` raised from the transport, naming neither the runner nor the field. It now checks serializability and raises `UnsubmittableRunnerError` instead, so the code matches what the module documents. Also assert `AgentEvaluatorJobResource.get_job_status()` against a live agent job. A review round asked whether it 404s, since the status route is built from `/evaluate/jobs` while agent jobs live under `/agent-evaluate/jobs`. It does not -- the status lookup ignores the collection prefix -- but nothing covered it, because the execution path polls through `nmp.testing` rather than this resource.

…et overload The taskset overload declared `metric: None = None` and `dataset: None = None` to express that neither belongs in a taskset submission. They had the opposite effect: `submit(tasks=..., metric=..., dataset=..., target=runner)` matched the overload and type-checked clean, leaving the runtime guard as the only defence. Removing them means no overload matches that call, so `ty` rejects it statically as well. Signed-off-by: Sandy Chapman <schapman@nvidia.com>

Summary
An evaluation someone got working locally with
AgentEvaluator()can now be submitted as a governed job, without retyping its configuration into a target spec and getting it subtly wrong. Before, a liveGymAgentTaskRunnercould only run in-process; there was no supported way to hand one to the platform. After,evaluator.submit(tasks=TasksetRef("default/my-suite"), target=runner)derives the target spec from the runner and the job runs the same evaluation.Related Issue
Tracked by AALGO-485 (no GitHub issue).
