## What it does

Mask Grounding DINO adds mask prediction to Grounding DINO, letting the model segment objects from text prompts. This skill guides training, evaluation, inference, export, and quantization, with dataset requirements laid out for each action.

Training uses AutoML by default when the packaged training schema and template are available. A request to turn AutoML off applies to that run only. Docker and nvidia-container-toolkit are required; without them, the environment does not meet the skill’s runtime requirements.

For a standalone setup outside the TAO skill bank plugin, run `tao-setup` first. Set `train.pretrained_model_path` to the model weights and pass dataset paths through `spec_overrides`. Supported dataset formats are `odvg`, `coco`, and `coco_raw`.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/tao-train-mask-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-mask-grounding-dino
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-mask-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-mask-grounding-dino/SKILL.md

## When to use it
- train Mask Grounding DINO on segmentation data
- evaluate a model checkpoint against test data
- find objects in images from text prompts
- prepare a model for export or quantization

## Example prompts
- Train Mask Grounding DINO on my segmentation dataset with AutoML enabled.
- Evaluate this model checkpoint against the test dataset.
- Run inference on these images and segment the objects named in my prompts.

# Mask 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).

Mask Grounding DINO for grounded instance segmentation. Extends Grounding DINO with mask prediction head for open-set segmentation guided by text prompts.

Set train.pretrained_model_path for full model weights.

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