## What it does

This skill guides TAO CenterPose workflows for training, model evaluation, inference, and export. CenterPose finds object centers and predicts keypoint locations. Its inference flow can use PnP for 6-DoF pose estimation, which requires camera intrinsics: focal lengths and principal-point coordinates.

The package includes action schemas and YAML spec templates. When AutoML is enabled, training is routed through `tao-skill-bank:tao-run-automl` if the training schema and matching template are available. Each action needs its data paths in the spec overrides; training uses separate train and validation datasets.

Docker and `nvidia-container-toolkit` are required. Set `model.backbone.pretrained_backbone_path` as well. TensorRT engine generation, TensorRT evaluation, and TensorRT inference use dedicated deploy templates. PnP inference cannot run without camera intrinsics.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- train CenterPose with train and validation datasets
- evaluate a model against test data
- run inference to estimate an object's pose
- export a model or generate a TensorRT engine

## Example prompts
- Train CenterPose on my train and validation datasets with AutoML enabled.
- Evaluate this CenterPose model on the test dataset and show its metrics.
- Run CenterPose inference for 6-DoF pose estimation using these camera intrinsics.

# CenterPose

> **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).

CenterPose for keypoint / pose estimation. Detects object centers and regresses keypoint locations. Used for 6-DoF object pose estimation.

Set model.backbone.pretrained_backbone_path.

For TAO Deploy TensorRT actions (`gen_trt_engine`, TensorRT `evaluate`, and TensorRT `inference`), use the deploy spec templates packaged 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.
