對于深度學習初學者來說，JupyterNoteBook的腳本運行形式顯然更加友好，依托Python語言的跨平臺特性，JupyterNoteBook既可以在本地線下環(huán)境運行，也可以在線上服務器上運行。GoogleColab作為免費GPU算力平臺的執(zhí)牛耳者，更是讓JupyterNoteBook的腳本運行形式如虎添翼。
本次我們利用Bert-vits2的最終版Bert-vits2-v2.3和JupyterNoteBook的腳本來復刻生化危機6的人氣角色艾達王(ada wong)。
本地調試JupyterNoteBook
眾所周知，GoogleColab雖然可以免費提供GPU讓用戶用于模型訓練和推理，但是每一個JupyterNoteBook文件腳本最多只能運行12小時，隨后就會被限制，所以為了避免浪費寶貴的GPU使用時間，我們可以在線下調試自己的JupyterNoteBook腳本，調試成功后，就可以把腳本直接上傳到GoogleColab平臺。
首先通過pip命令進行本地安裝：
python3 -m pip install jupyter
隨后運行啟動命令：
jupyter notebook
此時，訪問本地的notebook地址：
隨后選擇文件-》新建-》Notebook 即可。
輸入筆記內容：
#@title 查看顯卡
!nvidia-smi
點擊運行單元格：
程序返回：

注意2.3版本的底模是4個。
切分數(shù)據(jù)集
接著把艾達王的音頻素材上傳到Data/ada/raw/ada.wav
隨后新建單元格：
#@title 切分數(shù)據(jù)集
!python3 audio_slicer.py
素材就會被切分。
轉寫和標注
此時我們需要把切片素材轉寫：
#@title 轉寫和標注
!pip install git+https://github.com/openai/whisper.git
!python3 short_audio_transcribe.py
注意這里單獨安裝whisper，很多人直接用 pip install whisper，其實這不是正確的安裝方式，需要單獨指定安裝源：pip install git+https://github.com/openai/whisper.git，切記，否則會報錯。
執(zhí)行完畢后會在角色目錄生成轉寫文件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_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.
這里一共27條切片語音，對應27個轉寫文本，注意語言是英語。
音頻重新采樣
對素材音頻進行重新采樣的操作：
#@title 重新采樣
!python3 resample.py --sr 44100 --in_dir ./Data/ada/raw/ --out_dir ./Data/ada/wavs/
預處理標簽文件
接著處理轉寫文件，生成訓練集和驗證集：
#@title 預處理標簽文件
!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]

模型訓練
萬事俱備，開始訓練：
#@title 開始訓練
!python3 train_ms.py
模型會在models目錄生成，項目默認設置了訓練間隔是50步，可以根據(jù)自己的需求修改config.json配置文件。
模型推理
一般情況下，訓練了50步或者100步左右，可以推理一下查看效果，然后繼續(xù)訓練：
#@title 開始推理
!python3 webui.py
