# Button-Press Mini Demo

This folder is a tiny, self-contained test set for `button-press-topdown-v3`.

## Contents

- `samples.jsonl`: 5 demo samples (image path, instruction, state, gt_action)
- `images/`: copied JPEG frames for those samples
- `manifest.json`: dataset metadata
- `inference_results.jsonl`: created after running the demo script

## Run Inference on All 4 Shared Checkpoints

From `vla_project/` root:

```bash
./.venv/bin/python demo/run_button_press_demo.py
```

By default this runs on `1` sample for quick verification.

This runs `infer.py` on:

- `checkpoints/checkpoints_stage2_no_moe_unfreeze/best.pt`
- `checkpoints/checkpoints_stage2_moe_text_unfreeze/best.pt`
- `checkpoints/checkpoints_stage2_moe_full_unfreeze/best.pt`
- `checkpoints/checkpoints_stage2_moe_full_peg_only/best.pt`

and writes:

- `demo/button_press_mini/inference_results.jsonl`

## Optional: Run All 5 Samples

```bash
./.venv/bin/python demo/run_button_press_demo.py --max-samples 0
```
