# api.py usage
|
||||
|
||||
` python api.py -dr "123.wav" -dt "一二三。" -dl "zh" `
|
||||
|
||||
## 执行参数:
|
||||
|
||||
`-s` - `SoVITS模型路径, 可在 config.py 中指定`
|
||||
`-g` - `GPT模型路径, 可在 config.py 中指定`
|
||||
|
||||
调用请求缺少参考音频时使用
|
||||
`-dr` - `默认参考音频路径`
|
||||
`-dt` - `默认参考音频文本`
|
||||
`-dl` - `默认参考音频语种, "中文","英文","日文","zh","en","ja"`
|
||||
|
||||
`-d` - `推理设备, "cuda","cpu"`
|
||||
`-a` - `绑定地址, 默认"127.0.0.1"`
|
||||
`-p` - `绑定端口, 默认9880, 可在 config.py 中指定`
|
||||
`-fp` - `覆盖 config.py 使用全精度`
|
||||
`-hp` - `覆盖 config.py 使用半精度`
|
||||
|
||||
`-hb` - `cnhubert路径`
|
||||
`-b` - `bert路径`
|
||||
|
||||

### 推理
|

endpoint: `/`
|
||||
|
||||
使用执行参数指定的参考音频:
|
||||
GET:
|
||||
`http://127.0.0.1:9880?text=先帝创业未半而中道崩殂，今天下三分，益州疲弊，此诚危急存亡之秋也。&text_language=zh`
|
||||
POST:
|
||||
```json
|
||||
{
|
||||
"text": "先帝创业未半而中道崩殂，今天下三分，益州疲弊，此诚危急存亡之秋也。",
|
||||
"text_language": "zh"
|
||||
}

|
||||
手动指定当次推理所使用的参考音频:
|
||||
GET:
|
||||
`http://127.0.0.1:9880?refer_wav_path=123.wav&prompt_text=一二三。&prompt_language=zh&text=先帝创业未半而中道崩殂，今天下三分，益州疲弊，此诚危急存亡之秋也。&text_language=zh`
