The yolozu command is not found
- Verify
- Confirm which Python environment received the package, then run python3 -m yolozu --help from that same interpreter.
- Next action
- Reinstall into the intended environment; do not switch runtimes silently.
What can go wrong
Start from observed output, verify the relevant artifact, and change only the condition supported by evidence. A skipped or unavailable lane is not a successful result.
Symptom → verification → next action
doctor --proof fails
- Verify
- Read the errors and drift_hints in the doctor report. The proof is CPU-only and does not require a model download.
- Next action
- Resolve the reported package, path, or write-permission problem, then rerun into a fresh proof directory.
Predictions validation reports missing or migrated fields
- Verify
- Run strict validation on the wrapped artifact and compare its schema version with the predictions schema.
- Next action
- Fix the producer or use the documented migration path before scoring.
Dataset validation cannot resolve the split
- Verify
- Use the split recorded in the dataset/proof artifact instead of assuming train, val, or val2017.
- Next action
- Correct the dataset manifest or command so image IDs and split identity agree.
Two reports have different metrics
- Verify
- Compare task, dataset/split, prediction source, export settings, protocol identity, class mapping, thresholds, and skip reasons.
- Next action
- Align the differing input or protocol field before attributing the difference to a model or runtime.
A backend row is skipped or conditional
- Verify
- Read the canonical support matrix and the report's explicit status/reason.
- Next action
- Provide the required artifact/runtime or keep the lane skipped; never reinterpret it as successful parity.
A Research run changes the result
- Verify
- Verify that the stable baseline predictions and evaluation report are preserved and linked.
- Next action
- Treat the delta as Research evidence until a fixed protocol, rollback review, and environment qualification support a stronger conclusion.
The visible demo has no overlays
- Verify
- Confirm the demo report and overlays directory under the exact run directory printed by the command.
- Next action
- Rerun the instance-seg demo into a new run directory and inspect the reported output paths.
