One-click YuE2 installer runs music generation in realtime on a 6GB GPU, plus a cu128 pitfall

A developer released a one-click Windows installer for YuE2 music generation that runs roughly realtime on a 6GB laptop 4050: 1 minute of music in 61 seconds, 2 minutes in 118. The batch file installs ComfyUI, pulls YuE2 weights from the Comfy-Org repo, and opens a local page where you type style, lyrics, and length — no graph wiring needed.
Key lessons:
- The official package demands flash attention with no Windows build, and ran 22x slower than realtime with memory walls
- Costly pitfall: with torch cu128, ComfyUI silently disables its fast kernels (a one-line note says cu130+ is required); the same song took 328s instead of 61. The installer now reads your driver and picks cu130 (driver ≥580) or cu128
- Covers: feed in audio, SheetSage2 transcribes the melody, drag notes in a piano roll, and the model sings your lyrics — a 2-minute cover took 4 minutes end to end
- Weights pulled at runtime, CC BY-NC licensed (personal use only)
The author is asking whether it fits on 4GB cards.
