web-demo

Use this sub-skill when the task is about the browser experience: launch the demo, open the web UI, choose a checkpoint, click handle and target points, save an image or video, or troubleshoot the demo runtime.

Start here

1. Run the bundled preflight: ../../scripts/check_install.py --mode web
2. Launch the demo with the bundled wrapper: ../../scripts/launch_web_demo.py --device cuda --ip 0.0.0.0 --port 7860
3. Read references/workflows.md for the point-drag sequence and UI controls.
4. Read ../../references/checkpoints.md if you need model names or cache behavior.
5. Read references/troubleshooting.md if the UI opens but the interaction fails.

This sub-skill covers

• Launching the browser demo with the supported launch flags.
• Switching between checkpoints in the model dropdown.
• Creating a seeded image, placing handle and target points, and running Drag it.
• Resetting, undoing, and saving edited outputs.
• Understanding the saved draggan_tmp/ files and checkpoint cache usage.

This sub-skill does not cover

• Writing a custom Python script around draggan.draggan functions.
• Low-level tensor shapes, point encoding, or latent manipulation details.
• Claims that CPU or MPS is a verified drag backend.

Important cautions

• The verified drag path in this snapshot requires CUDA.
• The Draw a Mask tab is present in the UI, but the current optimizer does not enforce the mask.
• Uploaded-image inversion is experimental; treat it as a best-effort path rather than the default workflow.
• If you only need the install check or environment diagnosis, use the root scripts and troubleshooting reference first.

Helpful references

• references/workflows.md for the user-facing browser steps.
• references/troubleshooting.md for launch, model-download, and UI-specific failures.
• ../../references/deployment.md for install and launch modes shared with the root skill.
• ../../references/checkpoints.md for checkpoint names and the cache root.
