Full details: Benchmark Validation IntegrityExplanation 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 Resolution Resolve the measurement scope mismatch by ensuring equivalent measurement accounting: Option 1 (Recommended): Include preprocessing in the reference measurement path. - Modify Comment |

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_.

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 continuesthe merged classifier migrations without adding a shared model implementation.
Exit Criteria
IModelandIImageToClassScores, binds its own Task,and returns every class logit in checkpoint order.
acceptance rules; validate the original selected checkpoints and public SDK consumers.
current-head Pre-merge success.
Implementation
image_to_class_scores; return completeowned scores plus explicit checkpoint labels/vocabulary, or empty identity when unknown.
paths unchanged, including NFNet's center/squash crop policy.
consumers. Existing E2Es keep the JPEG CLI path and original top-1 oracle;
SDK consumers receive identical decoded RGB and compare all scores.
existing performance entry IDs through the family-owned reference protocol,
retaining workloads, precision, 3 warmups, 10 measurements and 5% margin.
Change categories
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.

preprocessing while the native Task includes family preprocessing; this existing
accounting difference is documented, not declared fixed.
Contributor Self-Review
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_DIRfor developmentconsumer binaries. Runtime and family DSOs upgrade together; old bundles must
be rebuilt. This branch does not depend on another migration batch.
Risk level
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
mainatef359c2a6cdd2a031a43bee4cc820bb40e87fca9.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 CTesttargets 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; thelater 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.
