AutoTrain vision and multimodal workflows

Use this sub-skill for image classification, image regression/scoring, object detection, and VLM dataset/task flows.

Supported entry points

• autotrain image-classification --help
• autotrain image-regression --help
• autotrain object-detection --help
• YAML aliases: image-classification, image-regression, image-scoring, object-detection, image-object-detection, vlm:captioning, vlm:vqa
• App/API task keys: image-classification, image-regression, image-object-detection, vlm:captioning, vlm:vqa

Important: there is no top-level autotrain vlm command in this checkout. Route VLM through the app/API/config flow.

Data-layout summary

Task	Local layout
image classification	directory with at least two class subfolders; each class folder has at least five jpg/jpeg/png files and no extra files/subfolders
image regression	directory with at least five images plus metadata.jsonl containing file_name and target
object detection	directory with at least five images plus metadata.jsonl containing file_name and objects
VLM	directory with at least five images plus metadata.jsonl containing file_name and all mapped text/prompt columns

Use scripts/validate_vision_data.py for bounded local layout checks.

Safe validation sequence

1. Inspect relevant CLI help with the root inspect_cli.py helper.
2. Validate YAML with the root validate_config.py helper.
3. Validate local image folders/metadata with scripts/validate_vision_data.py.
4. If VLM or UI/API parameters are involved, use ../app-backends/ to inspect app/API task params and backend auth.
5. Launch only after data layout, model id, task alias, backend, and Hub credentials are explicit.
