Bert-vits2-v2.2新版本本地训练推理整合包(原神八重神子英文模型miko)
近日，Bert-vits2-v2.2如约更新，该新版本v2.2主要把Emotion 模型换用CLAP多模态模型，推理支持输入text prompt提示词和audio prompt提示语音来进行引导风格化合成，让推理音色更具情感特色，并且推出了新的预处理webuI，操作上更加亲民和接地气。
更多情报请参见Bert-vits2官网：
https://github.com/fishaudio/Bert-VITS2/releases/tag/v2.2
与此同时，基于FastApi的推理web界面项目也同步适配了Bert-vits2-v2.2版本，官网如下：
https://github.com/jiangyuxiaoxiao/Bert-VITS2-UI
本次我们基于此两个项目来克隆原神角色八重神子的英文语音模型miko。
Bert-vits2-v2.2新的底模和情感模型
首先克隆Bert-vits2-v2.2官方项目：
git clone https://github.com/fishaudio/Bert-VITS2/tree/v2.2
安装依赖：
pip3 install -r requirements.txt
这里注意是v2.2的tag分支，因为官方随时都在更新，主分支可能会存在bug。
进入项目的目录：
cd /Bert-VITS2
随后下载新的底模和情感模型，下载地址：
https://openi.pcl.ac.cn/Stardust_minus/Bert-VITS2/modelmanage/show_model
将新的情感模型clap-hatsat-fused放入到项目的emotional目录，结构如下：
E:\work\Bert-VITS2-v22\emotional>tree /f
Folder PATH listing for volume myssd
Volume serial number is 7CE3-15AE

注意，wav2vec2-large-robust-12-ft-emotion-msp-dim是Bert-vits2-v2.1的情感模型，也需要保留，具体请移步：义无反顾马督工,Bert-vits2V210复刻马督工实践(Python3.10)， 这里不再赘述。
至此，新模型就配置好了。
Bert-vits2-v2.2模型训练
首先下载训练集，以原神角色八重神子的英文配音为例子，数据集下载地址：
https://github.com/AI-Hobbyist/Genshin_Datasets
随后新建miko角色目录
mkdir miko
将语音标注文件以esd.list命名，放入miko目录。
同时将分片语音素材放入raw目录。
最后新建miko/configs/config.json配置文件：

},
"version": "2.2"
}
这里注意"version": “2.2”，即版本号为最新的v2.2。
其他参数根据当前的设备环境酌情调整即可。
随后启动预处理页面：
python3 webui_preprocess.py
访问http://127.0.0.1:7860/:
按照页面的步骤进行操作即可，简单且方便。
操作完之后，运行训练命令：
python3 train_ms.py
训练好的模型放在data/miko/models目录，结构如下：
E:\work\Bert-VITS2-v22\Data\miko\models>tree /f

至此，训练环节结束。
Bert-vits2-v2.2模型推理
推理我们使用Bert-vits2-UI项目的页面，克隆web项目：
git clone https://github.com/jiangyuxiaoxiao/Bert-VITS2-UI
将Web项目放入Bert-vits2-v2.2的根目录中，目录结构如下：
E:\work\Bert-VITS2-v22_lilith\Web>tree /f
Folder PATH listing for volume myssd
Volume serial number is 7CE3-15AE

Hiyori.ico
这里包含主页面、样式文件以及JS文件，基于Hiyori。
随后启动推理页面:
python3 server_fastapi.py
访问：http://127.0.0.1:5000/：
加载模型进行推理即可。
此外，还可以基于FastAPI的接口进行推理，换句话说，发送http请求即可获取推理音频，接口参数如下：
