Troubleshooting ACE-Step v1.5 (2B)
If your ace step1.5 setup fails to generate audio or produces artifacts, start with small, controlled tests. Most issues are related to VRAM limits, dependency mismatches, or prompts that are too complex.
Common issues and fixes
- Out-of-memory errors: reduce duration, batch size, or sample rate.
- Silence in output: verify model weights and check output path.
- Artifacts or glitches: simplify prompts and avoid conflicting cues.
- Slow generation: close background apps and verify GPU utilization.
Diagnostics workflow
Run a short, known-good prompt and keep the settings minimal. If that succeeds, reintroduce complexity step by step. This isolates whether the issue is in the environment, the prompt, or the workflow.
Still stuck?
Review your install checklist and confirm GPU requirements. Most creators resolve issues by adjusting duration or prompt complexity.
