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:

./.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
