采用gpt-sovits方案，bert-sovits适合长音频训练，gpt-sovits运行短音频快速推理
## 部署tts推理
git clone https://github.com/RVC-Boss/GPT-SoVITS.git
## 1. 安装依赖库
```
conda create -n sovits python=3.9
conda activate sovits
bash install.sh
```

## 2. 下载模型文件
在GPT_SoVITS目录下执行
```python
from huggingface_hub import snapshot_download
snapshot_download('lj1995/GPT-SoVITS', local_dir='GPT_SoVITS/pretrained_models')
```
或者手动从 [GPT-SoVITS Models](https://huggingface.co/lj1995/GPT-SoVITS) 下载预训练模型，并将它们放置在 `GPT_SoVITS/GPT_SoVITS/pretrained_models` 中

最终文件目录如下
```
pretrained_models/
    --chinese-hubert-base
    --chinese-roberta-wwm-ext-large
    --gsv-v2final-pretrained
    s1bert25hz-2kh-longer-epoch=68e-step=50232.ckpt
    s2D488k.pth
    s2G488k.pth
```

## 3. 启动api服务
```
python api_v2.py
```
如果有错误提示找不到cmudict
```
import nltk
nltk.download('cmudict')
```
