That single file (Gemma4_vla.py) is all you need. It pulls the STT/TTS models and voice assets from Hugging Face on first run.

Not tied to these exact devices, any webcam, USB mic, and USB speaker that Linux sees should work.

build-essential and cmake are only needed if you go the native llama.cpp route (Option A in Step 4). The rest is for audio, webcam, and Python.

Heads up: this step may not be strictly necessary. But we're pushing this 8 GB board pretty hard with a fairly capable model, so giving ourselves some headroom makes the whole experience smoother, especially if you've been playing with Docker or other heavy stuff before this.
