## What it does

Grounding DINO locates whatever you describe in words. A DINO-style detector is paired with a BERT text encoder, so the model works without a fixed class vocabulary — prompts carry the labels. The skill walks the whole TAO path: training, evaluation, inference, export, quantization and TensorRT engine builds.

Full weights go through `train.pretrained_model_path`; backbone-only training uses `model.pretrained_backbone_path`. Training defaults to AutoML. The skill reads `references/skill_info.yaml`, and when `schemas/train.schema.json` and `references/spec_template_train.yaml` are both packaged it hands the run to `tao-skill-bank:tao-run-automl`. Ask for plain training and the run goes straight to the model instead.

Your data must be object_detection in odvg, coco or raw format. Data source paths are written per action, and nothing launches without them. TensorRT steps need `references/tao-deploy-grounding-dino.md` read first. Docker and nvidia-container-toolkit are required. If the session wasn't opened by the TAO skill bank plugin, run the `tao-setup` skill before installing — no host preflight and no credentials otherwise.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/tao-train-grounding-dino/SKILL.md

## When to use it
- train a detector on your own images and odvg annotations
- find objects from a short text description instead of a class list
- score a checkpoint by `test_mAP50`
- export the model and build a TensorRT engine
- quantize a trained model for inference

## Example prompts
- Train Grounding DINO on the dataset in `s3://bucket/data/train` with AutoML on
- Turn AutoML off and run 10 plain training epochs
- Evaluate the checkpoint on `images.tar.gz` with prompts “fire extinguisher” and “forklift”

# Grounding DINO

> **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).

Grounding DINO for open-set object detection. Combines DINO-style detection with BERT text encoder for language-guided detection. Detects objects described by text prompts without fixed class vocabulary.

Set train.pretrained_model_path for full Grounding DINO weights or model.pretrained_backbone_path for backbone-only.

For TAO Deploy TensorRT actions (`gen_trt_engine`, TensorRT `evaluate`, and TensorRT `inference`), read `references/tao-deploy-grounding-dino.md` first. 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.
