---

First-time Deployment

Prerequisites

• macOS with Apple Silicon (M1/M2/M3/M4)
• Python 3.10+

1. Create virtual environment

cd /path/to/skills/skills/qwen-tts
python3 -m venv venv
source venv/bin/activate

2. Install dependencies

模型从 ModelScope 镜像下载（国内更快）：

pip install -r scripts/requirements.txt

3. Pre-download model (optional)

首次运行时会自动下载模型。如需提前下载：

source venv/bin/activate
export HF_ENDPOINT="https://hf-mirror.com"
python3 -c "from mlx_audio.tts.utils import load_model; load_model('mlx-community/Qwen3-TTS-12Hz-0.6B-CustomVoice-4bit')"

4. Verify

source venv/bin/activate
python3 scripts/tts.py "你好，这是一段测试语音。" --output /tmp
# Should produce a WAV file in /tmp/

Troubleshooting

问题	解决方法
ModuleNotFoundError: mlx	确认使用 Apple Silicon Mac，MLX 不支持 Intel Mac
模型下载缓慢	设置 export HF_ENDPOINT="https://hf-mirror.com"
内存不足	4-bit 模型约需 1.5GB 内存，关闭其他大型应用
无声音输出	检查输出文件是否为 0 字节，可能是文本过短
