In `@python/tensorrt_model_connect/families/timm_resnet/model/model.py`:
- Around line 77-85: Retain all NumPy buffers passed to TensorRT weights until
network construction completes: update add_batch_norm and add_fc to register
their converted scale, shift, and w arrays in a builder-owned keepalive list,
then preserve that list through build_engine’s build_serialized_network call.
Ensure the list is initialized before helpers run and remains alive until the
build returns.
In `@python/tensorrt_model_connect/families/timm_resnet/plugin.py`:
- Around line 105-111: Update TimmResnetPlugin.matches so the generic "resnet"
model type is accepted only when the checkpoint is identified as a timm
checkpoint, preventing Hugging Face ResNetModel metadata from reaching this
loader. Preserve matching for timm architecture values such as "resnet50",
"resnext50_32x4d", and "wide_resnet", and route non-timm ResNet checkpoints to
their appropriate family if that mechanism already exists.
In `@src/runtime/models/timm_resnet/plugin_helpers.cpp`:
- Around line 395-406: Update write_kernel_so_to_temp to use the configured
temporary directory, sanitize global_name to an allowlisted safe filename, and
create the shared-object file with a unique exclusive mechanism that cannot
follow pre-existing symlinks. Check write and close failures before returning
the path so only a successfully written kernel file is loaded.
In `@tests/e2e/models/timm_resnet/e2e_plugins/references/custom_python.py`:
- Line 46: Resolve relative custom_python_script values from
case.metadata["model_test_dir"] rather than the repository-root calculation in
custom_python.py at
tests/e2e/models/timm_resnet/e2e_plugins/references/custom_python.py:46. Apply
the same model-local resolution rule to any relative golden_snapshot_path value
in tests/e2e/models/timm_resnet/e2e_plugins/references/golden_snapshot.py:51,
while preserving already-absolute paths.
In `@tests/validation/workloads.yaml`:
- Around line 1261-1264: Update default_model_names to include the ResNet model
names used by the timm_resnet family, ensuring the default validation plan
selects compatible ResNet models. Also revise the associated description to
refer to multiple checkpoints.
In `@website/data/model-support-matrix.md`:
- Around line 106-108: Update the three model-support-matrix entries for
timm/resnet18.a1_in1k, timm/resnet50.a1_in1k, and timm/resnext50_32x4d.a1h_in1k
so they are not marked 🟢 Green until release performance results demonstrate
the required GB300 comparison; preserve their accuracy information and use the
matrix’s existing deferred or pending status convention.

TensorRT Python API trt.Weights numpy array must remain alive until engine build lifetime
💡 Result:
In the NVIDIA TensorRT Python API, when you initialize a tensorrt.Weights object using a NumPy array, the TensorRT library does not create a deep copy of that array [1][2]. Instead, it holds a reference to the underlying data buffer [1][3]. Because of this reference-based behavior, the original NumPy array must remain alive and its memory must remain valid until the engine build process is complete [1][4]. If the NumPy array is deallocated or goes out of scope before the builder has finished using those weights to create the optimized engine, the engine will be built with invalid or corrupted data, leading to undefined behavior or crashes [4]. Key points regarding this requirement: - Reference, not copy: The Weights class holds a reference to the buffer of the NumPy array provided during initialization [1][2]. - Lifetime requirement: You must ensure that the NumPy array (e.g., as a local variable in a function or a member of a class) persists at least until the call to build the engine (e.g., builder.build_serialized_network) has finished [5][4]. - Refitting: If you intend to use the engine's refitting functionality, the underlying data must also remain valid through the refit process [4]. It is recommended to maintain a reference to your weights data (such as by storing it in a persistent list or as an attribute of an object) throughout the construction phase of your application [4].

Retain temporary TensorRT weight buffers until build_serialized_network returns. add_batch_norm creates temporary scale and shift arrays, and add_fc creates temporary w arrays before passing them to trt.Weights. build_engine calls build_serialized_network only after these helpers return. TensorRT does not copy the NumPy buffer, so the buffers can be released before the build completes. Keep each converted buffer alive in a builder-owned list through the build.

Hugging Face Transformers ResNetConfig model_type resnet ResNetModel state dict embedder conv1 layer1
💡 Result:
In the Hugging Face Transformers library, ResNet is implemented with the model_type set to "resnet" [1][2]. The architecture is defined by the ResNetConfig class, which supports customizing parameters such as layer_type ("basic" or "bottleneck"), depths, and hidden_sizes to define the model structure [2][3][4]. The ResNetModel architecture consists of an embedder, an encoder, and a pooler [5][6][7]. The embedder component, typically ResNetEmbeddings, contains the initial convolution layer often referred to as conv1, which processes the input pixel values [5][6][7]. The encoder then processes these embeddings through a sequence of stages (layer1, layer2, layer3, layer4), which are constructed based on the depths and layer_type specified in the configuration [2][5][4]. When inspecting the state dict of a ResNetModel, you will see these hierarchical components reflected in the parameter keys, such as embedder.conv1 for the initial convolution and encoder.layer1 for the first residual stage [5][6]. Top results: [2][5][6][4]

Restrict resnet matching to timm checkpoints. No other family claims resnet, and the metadata routes it to TimmResnetPlugin. A Hugging Face ResNetModel can therefore reach this loader, which expects root-level layer1.* and conv1.weight tensors instead of the model's embedder and encoder.layer1 layout. Reject non-timm checkpoints or route them to a dedicated family.

105 - 111, Update TimmResnetPlugin.matches so the generic "resnet" model type is
accepted only when the checkpoint is identified as a timm checkpoint, preventing
Hugging Face ResNetModel metadata from reaching this loader. Preserve matching
for timm architecture values such as "resnet50", "resnext50_32x4d", and
"wide_resnet", and route non-timm ResNet checkpoints to their appropriate family
if that mechanism already exists.

Path Traversal (CWE-22): Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reachability: Internal · Exploitability: Moderate
Create the kernel shared object with a confined, exclusive temporary path.
global_name comes from kernel_manifest.json, and the code replaces only . characters. A value such as /../../home/user/.bashrc produces /home/user/_bashrc.so after normalization. The predictable /tmp path also follows pre-existing symlinks. Use a configured temporary directory, restrict the name to safe characters, create the file exclusively with a unique name, and check write and close errors before loading it.

Resolve unresolved reference paths from the model directory.
Four parent traversals from references resolve to tests/e2e, not the repository root. custom_python_script is not normalized by manifest_loader, so relative scripts are passed to subprocess.run under the wrong base. Use case.metadata["model_test_dir"] or normalize this field.
golden_snapshot_path is normally normalized to an absolute model-local path. Apply the same model-local rule to any value that remains relative.

The timm_resnet builder recovers the stage layout from the checkpoint, so the basic-block and grouped-convolution variants need registration only, not builder changes. Adds E2E manifests and thresholds for timm/resnet18.a1_in1k and timm/resnext50_32x4d.a1h_in1k, registers both in the support matrix, HF metadata, validation workloads, and the release performance suite as additional profiles inheriting timm_resnet.classify, and updates the repository counters. Both were verified against an independent PyTorch reference when the family landed: resnet18 correlation 0.99999826 and resnext50 0.99999678, each with matching argmax and exact top-5 agreement.

Background
#1121 adds the
timm_resnetfamily withtimm/resnet50.a1_in1kas its onlyregistered checkpoint. The builder recovers the stage layout from the
checkpoint rather than from a depth table, so the basic-block and
grouped-convolution variants already build correctly and were verified during
that work, but neither is registered as a supported model.
Exit Criteria
timm/resnet18.a1_in1kandtimm/resnext50_32x4d.a1h_in1kare registeredcheckpoints with E2E manifests, validation workloads, and performance

Non-goal:
resnet34,resnet101,resnet152, andwide_resnetalso match thefamily prefixes but are not registered here.
Implementation
Registration only. Adds E2E manifests and thresholds for both checkpoints,
registers them in the support matrix, HF metadata, and validation workloads,
and adds them to the release performance suite as

Not Run / Remaining Gaps
exercised by the model proof; the parity evidence above comes from a direct
engine-versus-PyTorch comparison rather than the harness.
resnet34,resnet101,resnet152, andwide_resnetremain unregisteredand unverified.
Notes For Future Readers
Adding a further ResNet depth should need only a manifest, the shared
registration entries, and a counter bump. The builder is layout-driven, so no
graph code changes.
Note that
tools/model_ci.pyreads manifests from the committed tree viagit ls-tree, so a new manifest must be committed beforetest_nightly_inventory_exactly_matches_every_model_proof_selectionwill agreewith filesystem-based test selection.
Risk level
Registration only, no source change to the family, and the full CPU suite
passes.
