对于深度学习初学者来说，JupyterNoteBook的脚本运行形式显然更加友好，依托Python语言的跨平台特性，JupyterNoteBook既可以在本地线下环境运行，也可以在线上服务器上运行。GoogleColab作为免费GPU算力平台的执牛耳者，更是让JupyterNoteBook的脚本运行形式如虎添翼。
本次我们利用Bert-vits2的最终版Bert-vits2-v2.3和JupyterNoteBook的脚本来复刻生化危机6的人气角色艾达王(ada wong)。
本地调试JupyterNoteBook
众所周知，GoogleColab虽然可以免费提供GPU让用户用于模型训练和推理，但是每一个JupyterNoteBook文件脚本最多只能运行12小时，随后就会被限制，所以为了避免浪费宝贵的GPU使用时间，我们可以在线下调试自己的JupyterNoteBook脚本，调试成功后，就可以把脚本直接上传到GoogleColab平台。
首先通过pip命令进行本地安装：
python3 -m pip install jupyter
随后运行启动命令：
jupyter notebook
此时，访问本地的notebook地址：
随后选择文件-》新建-》Notebook 即可。
输入笔记内容：
#@title 查看显卡

点击运行单元格：

克隆代码库
接着克隆代码库：
#@title 克隆代码仓库
!git clone https://github.com/v3ucn/Bert-vits2-V2.3.git
程序返回：

安装项目依赖
随后进入项目的目录，安装依赖：
#@title 安装所需要的依赖
%cd /content/Bert-vits2-V2.3
!pip install -r requirements.txt
下载必要的模型
新增单元格，下载模型：

下载底模文件
接着下载预训练模型的底模：
#@title 下载底模文件

!wget -P Data/ada/models/ https://huggingface.co/OedoSoldier/Bert-VITS2-2.3/resolve/main/WD_0.pth
注意2.3版本的底模是4个。
切分数据集
接着把艾达王的音频素材上传到Data/ada/raw/ada.wav
随后新建单元格：
#@title 切分数据集
!python3 audio_slicer.py
素材就会被切分。
转写和标注
此时我们需要把切片素材转写：
#@title 转写和标注
!pip install git+https://github.com/openai/whisper.git
!python3 short_audio_transcribe.py
注意这里单独安装whisper，很多人直接用 pip install whisper，其实这不是正确的安装方式，需要单独指定安装源：pip install git+https://github.com/openai/whisper.git，切记，否则会报错。
执行完毕后会在角色目录生成转写文件esd.list:
./Data\ada\wavs\ada_0.wav|ada|EN|I do. The kind you like.
./Data\ada\wavs\ada_1.wav|ada|EN|Now where's the amber?
./Data\ada\wavs\ada_10.wav|ada|EN|Leave the girl. She's lost no matter what.
./Data\ada\wavs\ada_11.wav|ada|EN|You walk away now, and who knows?
./Data\ada\wavs\ada_12.wav|ada|EN|Maybe you'll live to meet me again.
./Data\ada\wavs\ada_13.wav|ada|EN|And I might get you that greeting you were looking for.
./Data\ada\wavs\ada_14.wav|ada|EN|How about we continue this discussion another time?
./Data\ada\wavs\ada_15.wav|ada|EN|Sorry, nothing yet.

./Data\ada\wavs\ada_17.wav|ada|EN|Quite the commotion.
./Data\ada\wavs\ada_18.wav|ada|EN|Everything will work out just fine.
./Data\ada\wavs\ada_19.wav|ada|EN|He's a good boy. Predictable.
./Data\ada\wavs\ada_2.wav|ada|EN|The deal was, we get you out of here when you deliver the amber. No amber, no protection, Louise.
./Data\ada\wavs\ada_20.wav|ada|EN|Nothing personal, Leon.
./Data\ada\wavs\ada_21.wav|ada|EN|Louise and I had an arrangement.
./Data\ada\wavs\ada_22.wav|ada|EN|Don't worry, I'll take good care of it.
./Data\ada\wavs\ada_23.wav|ada|EN|Just one question.
./Data\ada\wavs\ada_24.wav|ada|EN|What are you planning to do with this?
./Data\ada\wavs\ada_25.wav|ada|EN|So, we're talking millions of casualties?
./Data\ada\wavs\ada_26.wav|ada|EN|We're changing course. Now.
./Data\ada\wavs\ada_3.wav|ada|EN|You can stop right there, Leon.
./Data\ada\wavs\ada_4.wav|ada|EN|wouldn't make me use this.
./Data\ada\wavs\ada_5.wav|ada|EN|Would you? You don't seem surprised.
./Data\ada\wavs\ada_6.wav|ada|EN|Interesting.
./Data\ada\wavs\ada_7.wav|ada|EN|Not a bad move
./Data\ada\wavs\ada_8.wav|ada|EN|Very smooth. Ah, Leon.
./Data\ada\wavs\ada_9.wav|ada|EN|You know I don't work and tell.
这里一共27条切片语音，对应27个转写文本，注意语言是英语。
音频重新采样
对素材音频进行重新采样的操作：
#@title 重新采样
!python3 resample.py --sr 44100 --in_dir ./Data/ada/raw/ --out_dir ./Data/ada/wavs/
预处理标签文件
接着处理转写文件，生成训练集和验证集：
#@title 预处理标签文件
!python3 preprocess_text.py --transcription-path ./Data/ada/esd.list --t
程序返回：
pytorch_model.bin: 100% 1.32G/1.32G [00:10<00:00, 122MB/s]
spm.model: 100% 2.46M/2.46M [00:00<00:00, 115MB/s]

生成 BERT 特征文件
最后生成bert特征文件：

!python3 bert_gen.py --config-path ./Data/ada/configs/config.json
对应27个素材：
100% 27/27 [00:33<00:00, 1.25s/it]
bert生成完毕!, 共有27个bert.pt生成!
模型训练
万事俱备，开始训练：
#@title 开始训练
!python3 train_ms.py
模型会在models目录生成，项目默认设置了训练间隔是50步，可以根据自己的需求修改config.json配置文件。
模型推理
一般情况下，训练了50步或者100步左右，可以推理一下查看效果，然后继续训练：
#@title 开始推理
!python3 webui.py
返回：
