Run AnomalyGenNext 1.1 inference from a native testcase or a prepared generation plan, then publish validated fine-grained and binary COCO labels. Use for synthetic object-detection defect generation, not model training.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a workflow for generating synthetic object-detection defect images and corresponding COCO-format labels using the AnomalyGenNext 1.1 container. It supports both prepared input plans and native testcase execution. The process includes optional guardrails for content safety and produces validated fine-grained and binary defect annotations. This tool is strictly for synthetic data generation and does not perform model training or integrate outputs directly into training pools.

What it does

  • Runs AnomalyGenNext 1.1 inference to create synthetic defect images.
  • Generates fine-grained and binary COCO-format labels for detected defects.
  • Supports optional guardrails for text screening, image content safety, and face blurring.
  • Validates input integrity manifests and checkpoint paths before execution.
  • Produces a validation summary and status report for generated datasets.
  • Enforces strict container mount requirements for checkpoint and output directories.

When to use it

  • When you need to generate synthetic defect data for object detection tasks.
  • When you have prepared input data from the tao-prepare-anomalygennext-inputs workflow.
  • When you need to create binary or fine-grained COCO labels for anomaly detection.
  • When you require a controlled generation environment with optional safety guardrails.

Advantages

  • Automates the complex setup and execution of AnomalyGenNext inference.
  • Ensures consistent output formatting with validated COCO annotations.
  • Provides built-in safety mechanisms to screen generated content.
  • Strict validation of inputs and checkpoints prevents common runtime errors.

Usage examples

“Generate synthetic defects using my prepared input directory.”
The agent executes the generation script using the specified inputs-dir, base-checkpoint, and checkpoint-root, producing synthetic images and COCO labels in the output directory.
“Run AnomalyGenNext generation without guardrails.”
The agent triggers the generation process with the --no-guardrail flag, disabling text screening, image safety, and face blurring, ensuring the requested row count is fully generated.

Documentation by NVIDIA Corporation

Generate AnomalyGenNext OD Defects

This leaf uses the upstream generator and pseudo-labeler in the pinned public container. It does not prepare detector gaps, run AMP, train AnomalyGenNext, or append outputs to a detector training set. Read references/execution-contract.md when adapting input or completion behavior, and references/container-runtime.md before submission.

Inputs

Pass either:

  • --inputs-dir pointing to the completed output of tao-prepare-anomalygennext-inputs; or

  • --input-data-path, --checkpoint, and matching --recipe for a native AnomalyGenNext testcase.

Also provide the Cosmos3-Nano base checkpoint, the complete AnomalyGenNext checkpoint root, and one or more GPUs. Every testcase image and aligned mask must exist, every anomaly type must occur in the recipe, and the requested row count must match the testcase. When a prepared integrity manifest exists, every recorded hash is verified before generation.

Run

Invoke tao-launch-workflow, review the exact image, mounts, GPU shape, runtime, and output directory, then submit the generate action:

scripts/generate_od_defects.py \
  --inputs-dir /results/prepared_inputs \
  --base-checkpoint /models/Cosmos3-Nano \
  --checkpoint-root /workspace/paidf-anomalygen/checkpoints \
  --output-dir /temporary/generation \
  --published-root /persistent/generation \
  --no-guardrail \
  --num-gpus 1

When execution uses temporary storage, --published-root records the persistent locations that will contain the saved results.

Guardrails are enabled by default and preserve the native invocation without a guardrail flag. The wrapper appends --no-guardrail only when explicitly disabled. --no-guardrail disables text screening, image content-safety screening, and face blurring together. The checkpoint root is mounted over the image's canonical /workspace/paidf-anomalygen/checkpoints tree and validated before GPU work. The Nano tokenizer, Edge processor, and DINOv2 assets are always required; guardrail-enabled runs additionally require the Qwen3Guard and Cosmos Guardrail repositories. Generation is forced offline after validation. The selected platform must honor the declared checkpoint_root.container_path; the generation leaf rejects a different mount point. The base-checkpoint argument remains separate: it is the parent containing checkpoint.json and the model/ checkpoint directory.

Completion

For each dataset, generated + guardrail_blocked must equal requested rows. With --no-guardrail, generated must equal requested rows and guardrail_blocked remains zero. The validation summary records the selected guardrail mode. The pseudo-label count must match generated images, each image needs an annotation, categories must be declared anomaly types, and every COCO bbox must be positive and inside its image. The action emits:

DATASET/raw/
DATASET/pseudo_labels/coco_annotations.json
pseudo_labels/coco_annotations.json
pseudo_labels/coco_annotations_od_defect.json
validation_summary.json
status.json

The native COCO preserves TEXTURE+DEFECT categories. The binary file maps all annotations to defect. Only a calling application may admit these outputs to training; this leaf always reports training_pool_mutated=false.

Files

references/container-runtime.md

AnomalyGenNext 1.1 container runtime

Read this before submitting generation.

Resolve the image through references/skill_info.yaml:

nvcr.io/nvidia/paidf-anomalygen:1.1.0

The image contains AnomalyGenNext 1.1 and its runtime at /workspace/paidf-anomalygen. Do not substitute the older 1.0 image and do not overlay an external checkout or host virtualenv.

Expose the testcase or prepared-input result, task checkpoint and recipe, Cosmos3-Nano base checkpoint, complete checkpoint root, this skill directory, and a new durable output directory. Preserve absolute paths or rewrite all related paths consistently inside the compute frame. The platform owns writable temporary storage and caches.

The image defaults to the non-root anomalygen user with UID 10000. Every input mount must be readable and traversable by the effective container user; every output, temporary, and cache mount must be writable. Before starting Python, use the selected image, mounts, and runtime identity to create and remove a nested temporary file in each writable mount. Stop on failure and report the affected host path with its ownership and mode. If the platform maps the process to the host user instead, that identity must resolve to a username and all home and cache locations must remain writable. For the local Docker identity-mapping recipe, see Running in Docker.

Mount the complete checkpoint root read-only at /workspace/paidf-anomalygen/checkpoints. The action rejects any other mount location. It always validates Qwen/Qwen3-VL-8B-Instruct and nvidia/Cosmos3-Edge in the Hugging Face cache under hf/, plus a Transformers-compatible facebook/dinov2-large.

The wrapper preserves the native default invocation when guardrails are on and passes --no-guardrail only when they are explicitly disabled. The flag disables text screening, image content-safety screening, and face blurring together. When guardrails are enabled, validation also requires Qwen/Qwen3Guard-Gen-0.6B and nvidia/Cosmos-Guardrail1; those repositories are not required with --no-guardrail. It then forces Hugging Face and Transformers offline. Missing assets fail before sampling. Keep registry and Hugging Face credentials out of specs, commands, logs, and job records.

Invoke the command declared in skill_info.yaml, for example inside the container:

python /opt/tao-generate-od-defects/scripts/generate_od_defects.py \
  --inputs-dir /inputs/prepared \
  --base-checkpoint /models/Cosmos3-Nano \
  --checkpoint-root /workspace/paidf-anomalygen/checkpoints \
  --output-dir /results/generation \
  --no-guardrail \
  --num-gpus 1

The exposed GPU count must match --num-gpus. The output directory must not already exist. The base path must contain checkpoint.json and the model/ checkpoint directory; it is not the shared checkpoint root. Read execution-contract.md for the completion and accounting gates.
