## What it does

This skill guides workflows for the Deformable DETR 2D object detector in NVIDIA TAO Toolkit. The model uses deformable attention for multi-scale feature processing. It is lighter than DINO while keeping competitive accuracy. Supported model actions include `train`, `evaluate`, `inference`, `export`, and `quantize`. Running `gen_trt_engine` requires the TAO Deploy container because the PyTorch container does not support this subtask natively.

Datasets must use `coco` or `coco_raw` formats. Specifying data sources is mandatory for every action via `spec_overrides`. By default, the skill sets `automl_policy: on` and routes training through `tao-skill-bank:tao-run-automl`. You can turn off AutoML by requesting plain training or writing "disable AutoML".

Without `docker` and `nvidia-container-toolkit`, the containers cannot start. If this session did not start through the TAO skill bank plugin, run `tao-setup` first to handle credentials and preflight checks.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-deformable-detr -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tao-train-deformable-detr/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tao-train-deformable-detr/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-deformable-detr -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tao-train-deformable-detr/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-deformable-detr -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tao-train-deformable-detr/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills tao-train-deformable-detr
```

2. **Manually: put the files in place**
- File: `.github/skills/tao-train-deformable-detr/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-deformable-detr -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/tao-train-deformable-detr
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tao-train-deformable-detr/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-deformable-detr -a opencode
```

## When to use it
- train a Deformable DETR 2D object detector on COCO datasets
- optimize training hyperparameters using AutoML policies
- export and quantize model checkpoints for deployment
- configure dataset source paths and evaluation specs

## Example prompts
- train deformable-detr using coco annotations from `s3://bucket/data/train`
- run Deformable DETR object detection evaluation with plain training
- quantize Deformable DETR checkpoints for deployment

# Deformable DETR

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

Deformable DETR for 2D object detection. Uses deformable attention for efficient multi-scale feature processing. Lighter than DINO with competitive accuracy.

Uses pretrained weights. Set `model.pretrained_backbone_path` for backbone-only
loading or `train.pretrained_model_path` for full model initialization.

Supported parent model actions are `train`, `evaluate`, `inference`, `export`, and `quantize`. The PyT model container does not support a native `gen_trt_engine` subtask for this network. The `gen_trt_engine` action declared in `references/skill_info.yaml` must run with the TAO Deploy container. Deploy spec templates live in this skill's `references/` folder with the `spec_template_deploy_*.yaml` prefix.

## Dataclass Schemas

Generated TAO Core schemas are packaged in `schemas/<action>.schema.json`, with `schemas/manifest.json` listing available actions. Each generated schema also emits `references/spec_template_<action>.yaml` from the schema top-level `default` field. AutoML enablement is declared at the model layer in `references/skill_info.yaml` via `automl_enabled`. Runnable AutoML for an action requires `schemas/<action>.schema.json` and `references/spec_template_<action>.yaml` to exist and parse. Use the packaged selected-action schema for `automl_default_parameters`, `automl_disabled_parameters`, defaults, min/max bounds, enums, option weights, math conditions, dependencies, and popular parameters. Do not expect `~/tao-core` at runtime; maintainers regenerate schemas/templates before packaging the skill bank.
