Background

Migrate ten remaining timm classifier families to the existing Task SDK:
DPN, HRNet, MNASNet, NFNet, RepVGG, Res2Net, SENet, SE-ResNet, VGG and Xception.
All changes stay in their owning families/timm_*/ directories. This continues
the merged classifier migrations without adding a shared model implementation.

Exit Criteria

  • Each family implements IModel and IImageToClassScores, binds its own Task,
    and returns every class logit in checkpoint order.
  • Preserve model computation, preprocessing, declared profiles and existing
    acceptance rules; validate the original selected checkpoints and public SDK consumers.
  • Required remote checks must pass before merge. This submission does not claim
    current-head Pre-merge success.

Implementation

  • Change owned support/build/manifests to image_to_class_scores; return complete
    owned scores plus explicit checkpoint labels/vocabulary, or empty identity when unknown.
  • Keep graph, weights, preprocessing implementations and original reference
    paths unchanged, including NFNet's center/squash crop policy.
  • Add family-local CPU binding/metadata/lifetime tests and public C11/C++17
    consumers. Existing E2Es keep the JPEG CLI path and original top-1 oracle;
    SDK consumers receive identical decoded RGB and compare all scores.
  • Wire consumers through each family's existing CTest dependencies. Take over
    existing performance entry IDs through the family-owned reference protocol,
    retaining workloads, precision, 3 warmups, 10 measurements and 5% margin.
  • No Core, shared header, registry, CLI, workflow, dependency or sibling-family changes.

Change categories

  • Model or runtime behavior
  • Public API
  • ABI
  • Bundle or artifact format
  • Dependencies
  • Documentation only
  • CI or developer tooling

Public C layouts and bundle format 1 are unchanged. Family primary Task and runtime
metadata change; rebuild existing bundles. No legacy family interface or fallback is added.

MNASNet was brought through a minimal real end-to-end path before expanding the
other nine families. All ten original benchmark workloads then executed using the
existing suite resolver, native worker, family-reference command builder and
output-contract checker. All ten output contracts passed; each native and reference
result retained 1000 scores. This is execution/output evidence, not speedup qualification.

Not Run / Remaining Gaps

  • No Multi-Device, full Nightly, complete package or all-profile GPU qualification.
    DPN92, NFNet F3, Res2Net50d and Res2NeXt50 remain declared but were not GPU-selected.
  • No latency equivalence or improvement claim. Reference timing still excludes
    preprocessing while the native Task includes family preprocessing; this existing
    accounting difference is documented, not declared fixed.
  • Remote Pre-merge is pending at submission.

Contributor Self-Review

  • I have completed a self-review of this change.

Reviewed ownership, original computation/preprocessing and validation criteria,
complete output metadata, consumer wiring and benchmark timing boundaries.

Notes For Future Readers

Review one family from support/builder metadata through runtime binding and its
CPU/E2E tests. The other families intentionally duplicate owned code rather than
depending on each other. Use existing TRTMC_NATIVE_BUILD_DIR for development
consumer binaries. Runtime and family DSOs upgrade together; old bundles must
be rebuilt. This branch does not depend on another migration batch.

Risk level

  • Low
  • Medium
  • High

Ten family Task identities change, but their computation and acceptance criteria
are preserved and each selected official model was exercised end to end.

Review Follow-up

Rebased onto main at ef359c2a6cdd2a031a43bee4cc820bb40e87fca9.
Updated head: 9d4a8b2658684a3f78cb6025bf1aefa774d2fa08.

All ten family constructors now reject supplied blank label names when no
vocabulary identity is declared. Entirely absent labels, fully named labels,
and explicit vocabulary identities retain their existing meaning. The new
regression failed before the fix; no graph, weights, preprocessing, reference
or numerical acceptance rule changed.

Each owner also supplies dependency-free identity/default-Task tests, following
the existing support-test pattern required by current main. Both the real family
identity and rejection of an unrelated identity are exercised; no shared gate changed.

At revision a9221a6, the native rebuild passed, all twenty existing CTest
targets passed, and owner Python tests reported 328 passed / 14 explicitly
unselected E2E cases skipped. The full ten-checkpoint GPU and benchmark results
above belong to the original recorded revision, not to this updated head.
Remote checks must complete again before merge.

The updated runtime was also exercised with the retained MNASNet bundle: the
fresh CLI and original timm reference both returned top-1 class 656; both public
C/C++ consumers returned identical complete 1000-score payloads and preserved
unknown label/vocabulary metadata. This used runtime revision 6b77b18; the
later commits add support tests and the build-time validation ordering below,
without changing runtime inference. No engine rebuild was needed for that probe.
The JPEG CLI and decoded-RGB SDK paths are not claimed to have bitwise-equal logits.

The remaining build-time review finding is also fixed: existing metadata checks
now run before engine construction. Eight function-based builders validate before
opening weights; MNASNet and VGG reuse their existing metadata extraction after
weight loading but before engine construction. No new validation layer or rule
was added. A call-order regression failed on the old implementation; the final
owner Python suite passes 330 tests with 14 explicitly unselected E2E skips.
Model topology, engine construction, preprocessing and output metadata are unchanged.

📝 Summary

Summary

Migrates ten remaining TIMM classifier families to the Task SDK:

  • DPN, HRNet, MNASNet, NFNet, RepVGG
  • Res2Net, SENet, SE-ResNet, VGG, Xception

Each family now implements IModel and IImageToClassScores, uses image_to_class_scores, returns complete logits, and publishes class metadata. Family-local contract tests, metadata tests, documentation, C/C++ SDK consumers, E2E checks, and performance-reference wiring are included.

Existing bundles require rebuilding because task identities and runtime metadata changed.

Architecture impact

  • Changes remain within the owning family directories.
  • Pipelines consume existing shared Task SDK contracts.
  • Public SDK consumers depend on trtmc_c.
  • No new cross-family implementation or central registry is reported.
  • Remote, multi-device, full-nightly, complete-package, GPU-profile, and latency qualification remain pending.
  • The supplied diff output contains no changed-file evidence, so shared-surface and blast-radius claims cannot be independently verified here.

Validation

Reported results:

  • 20/20 native contract and preprocessing tests.
  • 308 Python tests.
  • Ten selected checkpoint E2E tests.
  • Source-quality checks.
  • Output-contract verification.

Review finding counts are unavailable.

Outcome

HUMAN REVIEW REQUIRED

The available evidence does not resolve the changed-file scope or the remaining qualification coverage.

Walkthrough

Ten TIMM families replace the legacy classification task with image_to_class_scores. Their pipelines return complete logits and optional vocabulary and label metadata. The changes add request validation, C and C++ SDK consumers, contract and end-to-end tests, performance references, and documentation.

Full details: Benchmark Validation Integrity

Explanation

The PR introduces benchmark measurement scope misalignment across all ten migrated families (DPN, HRNet, MNASNet, NFNet, RepVGG, Res2Net, SENet, SE-ResNet, VGG, Xception). Evidence of the timing integrity violation: 1. Reference measurement scope: Reference scripts declare TIMING = {"input_preparation_included": False, ...} and measure only model(inputs) during inference, excluding preprocessing. 2. Native Task measurement scope: Each family's TimmXxxImageClassificationPipeline::run() method includes family preprocessing as part of its execution path. For example, timm_dpn calls preprocess_timm_dpn_image() before model_->forward(). 3. Measurement mismatch: The two compared implementations measure different semantic regions: - Reference: Model inference only (timing starts after preprocessing) - Native Task: Preprocessing + model inference (timing includes preprocessing) 4. Check condition violation: This matches the explicit failure condition: "synchronization, device-to-host transfer, reduction, output validation, or serialization is included on only one side." Family preprocessing is included on the native side only. 5. Documentation vs. implementation: The PR documentation acknowledges this as "existing accounting difference" (timm_dpn README: "The existing reference policy still excludes input preparation...while the native public Task call includes family preprocessing"), but this is not an existing difference—it is newly introduced by this PR. Before the PR, these families used the legacy IImageClassification interface which did not participate in benchmark timing; they had no performance.yaml or performance_reference.py entries. 6. Test validation gap: Test files verify only that the reported metadata matches the TIMING constant (assert result["measurement_policy"] == reference.TIMING). They do not verify that the actual measurement scope equals the declared scope. The test is a meta-test that checks the reference script's honesty about its own behavior, not the equivalence of native and reference measurements. Affected files: All ten families have identical patterns: - families/timm_dpn/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_hrnet/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_mnasnet/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_nfnet/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_repvgg/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_res2net/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_senet/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_seresnet/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_vgg/tests/performance_reference.py, performance.yaml, test_performance_reference.py - families/timm_xception/tests/performance_reference.py, performance.yaml, test_performance_reference.py

Resolution

Resolve the measurement scope mismatch by ensuring equivalent measurement accounting: Option 1 (Recommended): Include preprocessing in the reference measurement path. - Modify _load_reference() in each family's performance_reference.py to apply the same preprocessing logic used in the native Task. - Move preprocessing inside the invoke() function so it is included in the timed region. - Update TIMING constant to set "input_preparation_included": True in all ten families. - Update performance.yaml baseline configuration to declare input_preparation_included: true. Option 2: Exclude preprocessing from the native Task measurement path (not recommended). - Modify each family's TimmXxxImageClassificationPipeline::run() to accept preprocessed float32 input, removing preprocessing from the Task SDK path. - Move preprocessing responsibility to the caller (benchmark worker). - This introduces additional complexity and differs from other Task SDK implementations. Option 1 implementation steps: 1. For each family, modify performance_reference.py: - Import and apply the family's preprocessing function (align with runtime/preprocessing headers). - Replace inputs = transform(image).to(device, dtype) with the family-specific preprocessing call used in pipeline.cpp. - Ensure invoke() calls the model with preprocessed input to match native Task timing. 2. Update TIMING in each family to "input_preparation_included": True. 3. Update each performance.yaml to declare input_preparation_included: true in the baseline configuration. 4. Update test assertions in test_performance_reference.py to verify the updated TIMING constant. 5. Update README documentation to clarify the measurement scope includes family preprocessing in both paths.

In `@families/timm_dpn/runtime/pipeline.cpp`:
- Around line 38-40: Update the constructor validation near the existing
num_classes_ and labels_ checks to reject any empty label when vocabulary_id_ is
empty, preserving empty labels when vocabulary_id_ is explicit. Use the existing
metadata validation pattern and throw a runtime error for invalid
unknown-vocabulary labels so run() cannot propagate an empty label.

In `@families/timm_hrnet/runtime/pipeline.cpp`:
- Around line 38-40: Update the constructor validation near num_classes_ and
labels_ so that when vocabulary_id_ is empty, every label in labels_ must be
nonempty and invalid metadata throws a runtime error; preserve empty labels when
vocabulary_id_ is nonempty.

In `@families/timm_mnasnet/runtime/pipeline.cpp`:
- Around line 37-39: Update the constructor validation around num_classes_,
labels_, and vocabulary_id_ to reject any empty label when vocabulary_id_ is
empty, while preserving the existing class-count and label-count checks. Use the
appropriate standard-library predicate support and ensure matching non-empty
labels remain accepted.

In `@families/timm_nfnet/runtime/pipeline.cpp`:
- Around line 38-40: Update the constructor validation near the existing
num_classes_ and labels_ checks to reject any empty label when vocabulary_id_ is
empty, while allowing empty labels when vocabulary_id_ is non-empty. Preserve
the current label-count validation and add a constructor contract test covering
an empty vocabulary_id_ with an empty label.

In `@families/timm_repvgg/runtime/pipeline.cpp`:
- Around line 38-40: Update the constructor validation following the existing
class-metadata check to reject any empty entry in labels_ only when
vocabulary_id_ is empty, raising a runtime error consistent with the existing
metadata validation. Preserve acceptance of empty label entries when an explicit
vocabulary identity is provided.

In `@families/timm_res2net/runtime/pipeline.cpp`:
- Around line 38-40: Update the validation around the existing num_classes_ and
labels_ checks to reject empty labels when vocabulary_id_ is empty, while
allowing them when an explicit vocabulary_id_ identifies the classes. Validate
label contents only in the empty-vocabulary case and preserve the existing size
consistency check.

In `@families/timm_senet/runtime/pipeline.cpp`:
- Around line 38-40: Update the SENet constructor validation around the existing
class-metadata check to reject any empty label when labels are provided without
a vocabulary_id_. Use the existing labels_ and vocabulary_id_ symbols, adding
the necessary standard algorithm support, while preserving the current
class-count validation and exception behavior.

In `@families/timm_seresnet/runtime/pipeline.cpp`:
- Around line 38-40: Update the SE-ResNet constructor validation after the
existing class metadata check to reject any empty label when vocabulary_id_ is
empty; iterate labels_ and throw the specified runtime error on the first empty
entry, while preserving valid vocabulary-backed labels and existing size
validation.

In `@families/timm_vgg/runtime/pipeline.cpp`:
- Around line 37-39: Update the VGG constructor validation near the existing
num_classes_ and labels_ size check: when vocabulary_id_ is empty, iterate over
labels_ and reject any empty label by throwing the specified runtime error.
Preserve the current class-count validation and allow empty label strings when
vocabulary_id_ is present.

In `@families/timm_xception/model.py`:
- Around line 371-379: Move the vocabulary_id and label_names validation from
after _build_engine to immediately after _read_config in build. Use
_preprocess_config(raw)["num_classes"] for the label-count check before engine
construction, while preserving the existing validation rules and error messages.

In `@families/timm_xception/runtime/pipeline.cpp`:
- Around line 38-40: Update the constructor validation around num_classes_,
labels_, and vocabulary_id_ to reject any empty label when vocabulary_id_ is
empty, while continuing to allow empty label entries when vocabulary_id_ is
non-empty. Preserve the existing class-count and labels-size validation, using
the appropriate standard algorithm to inspect labels_.

Implement family-owned ImageToClassScores bindings and complete checkpoint-order logits. Preserve each graph, weight loader, image preprocessing policy, declared profile and original reference oracle.

Exercise public C and C++ consumers through the existing family E2Es and CTest dependencies. Keep performance workloads and output contracts with family-owned references; no shared implementation or sibling dependency is added.

Fixed in a9221a6e27d0e59ac56e895a7aa41fada8442a8f across all ten family-owned constructors. Supplied blank labels are rejected at load time when the vocabulary is unknown; absent labels, fully named labels and explicit vocabulary identities remain supported. Added positive and negative CPU regressions: the negative case failed before the fix, and all twenty family contract/preprocessing tests now pass. Each owner also has dependency-free support-discovery tests required by current main (328 owner Python tests passed). Model math, preprocessing and original numerical acceptance rules are unchanged.

Reuse existing family metadata checks before TensorRT engine construction. Preserve valid metadata and error rules, and verify invalid metadata never calls the engine builder.

The remaining build-time finding is fixed in 9d4a8b2658684a3f78cb6025bf1aefa774d2fa08. All ten families now validate existing class metadata before engine construction. Eight builders do so before opening weights; MNASNet and VGG reuse their existing metadata extraction after weight loading but before building the engine. The regression failed on the old order and now verifies that invalid metadata never calls the engine builder. All 330 owner Python tests pass, with 14 unselected E2E cases skipped. Validation rules, model computation and acceptance thresholds are unchanged.
