## What it does

This skill guides image classification workflows within the NVIDIA TAO framework. It manages spec files for backbones like ResNet and EfficientNet, handling tasks from baseline training to model distillation. It also covers quantization and exporting artifacts for TensorRT inference.

AutoML is enabled by default for training runs unless explicitly turned off in the prompt. If you install this skill independently without the TAO skill bank plugin, execute `tao-setup` first to configure host credentials. Local Docker runs require extracted image directories. Passing compressed tar.gz files directly will fail.

Docker and nvidia-container-toolkit are mandatory prerequisites. The `dataset.root_dir` parameter must point to a writable bind mount because the dataset setup script generates a `classes.txt` file at runtime.

## Requirements
- Works with: Docker

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- train PyTorch image classifiers on ResNet or EfficientNet architectures
- configure model distillation and quantization for edge deployment
- export trained weights to generate TensorRT execution engines
- run hyperparameter search via integrated AutoML routines

## Example prompts
- Train an image classifier using the ResNet50 backbone with AutoML disabled
- Set up model quantization spec files with paths to my evaluation dataset
- Export the PyTorch classification checkpoint to prepare a TensorRT engine

# Classification PyT

> **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).

PyTorch image classification. Supports a wide range of backbones (FAN, EfficientNet, ResNet, etc.) with distillation and quantization for deployment.

Set model.backbone.pretrained_backbone_path for backbone weights or train.pretrained_model_path for full model.

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