本文主要是介绍云端开炉,线上训练,Bert-vits2-v2.2云端线上训练和推理实践(基于GoogleColab)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
假如我们一定要说深度学习入门会有一定的门槛，那么设备成本是一个无法避开的话题。深度学习模型通常需要大量的计算资源来进行训练和推理。较大规模的深度学习模型和复杂的数据集需要更高的计算能力才能进行有效的训练。因此，训练深度学习模型可能需要使用高性能的计算设备，如图形处理器（GPU）或专用的深度学习处理器（如TPU），这让很多本地没有N卡的同学望而却步。
GoogleColab是由Google提供的一种基于云的免费Jupyter笔记本环境。它可以帮助入门用户轻松地进行机器学习和深度学习的实验。
尽管GoogleColab提供了很多便利和免费的功能，但也有一些限制。例如，每个会话的计算资源可能是有限的，并且会话可能会在一段时间后自动关闭。此外，Colab的使用可能受到Google的限制和政策规定。
对于笔者这样的穷哥们来讲，GoogleColab就是黑暗中的一道光，就算有训练时长限制，也能凑合用了，要啥自行车？要饭咱也就别嫌饭馊了，本次我们基于GoogleColab在云端训练和推理Bert-vits2-v2.2项目，复刻那黑破坏神角色莉莉丝(lilith)。
配置云端设备
首先进入GoogleColab实验室官网：
https://colab.research.google.com/
点击新建笔记，并且链接设备服务器：
这里硬件设备选择T4GPU。
随后新建一条命令
#@title 查看显卡
!nvidia-smi
点击运行程序返回：

克隆代码仓库
随后新建命令：
#@title 克隆代码仓库
!git clone https://github.com/v3ucn/Bert-vits2-V2.2.git程序返回：

安装所需要的依赖
新建安装依赖命令：
#@title 安装所需要的依赖
%cd /content/Bert-vits2-V2.2
!pip install -r requirements.txt
依赖安装的时间要长一些，需要耐心等待。
下载必要的模型
接着下载必要的模型，这里包括bert模型和情感模型：
#@title 下载必要的模型

!wget -P bert/deberta-v2-large-japanese/ https://huggingface.co/ku-nlp/deberta-v2-large-japanese/resolve/main/pytorch_model.bin
如果推理任务只需要中文语音，那么下载前三个模型即可。
下载底模文件
随后下载Bert-vits2-v2.2底模：
#@title 下载底模文件 !wget -P Data/lilith/models/ https://huggingface.co/OedoSoldier/Bert-VITS2-2.2-CLAP/resolve/main/DUR_0.pth
!wget -P Data/lilith/models/ https://huggingface.co/OedoSoldier/Bert-VITS2-2.2-CLAP/resolve/main/D_0.pth
!wget -P Data/lilith/models/ https://huggingface.co/OedoSoldier/Bert-VITS2-2.2-CLAP/resolve/main/G_0.pth
注意这里的底模要放在角色的models目录中，同时注意底模版本是2.2。
上传音频素材和重采样
随后打开目录，在lilith目录右键新建文件夹raw，接着右键点击上传，将素材上传到云端：
同时也将转写文件esd.list右键上传到项目的lilith目录：

至于音频如何切分、转写、标注等操作，请移步：本地训练,立等可取,30秒音频素材复刻霉霉讲中文音色基于Bert-VITS2V2.0.2。囿于篇幅，这里不再赘述。
确保素材切分和转写文件都上传成功后，新建命令：
#@title 重采样
!python3 resample.py --sr 44100 --in_dir ./Data/lilith/raw/ --out_dir ./Data/lilith/wavs/
进行重采样操作。
预处理标签文件
接着新建命令：
#@title 预处理标签文件
!python3 preprocess_text.py --transcription-path ./Data/lilith/esd.list --train-path ./Data/lilith/train.list --val-path ./Data/lilith/val.list --config-path ./Data/lilith/configs/config.json

训练集和验证集生成完成！
此时，在lilith目录已经生成训练集和验证集，即train.list和val.list。
生成 BERT 特征文件
接着新建命令：
#@title 生成 BERT 特征文件
!python3 bert_gen.py --config-path ./Data/lilith/configs/config.json
程序返回：

- This IS expected if you are initializing BertForMaskedLM from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing BertForMaskedLM from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).

bert生成完毕!, 共有36个bert.pt生成!
数一下，一共36个，和音频素材数量一致。
生成 clap 特征文件
最后生成clap情感特征文件：
#@title 生成 clap 特征文件
#!wget -P emotional/clap-htsat-fused/ https://huggingface.co/laion/clap-htsat-fused/resolve/main/pytorch_model.bin
!python3 clap_gen.py --config-path ./Data/lilith/configs/config.json

由此就在底模的基础上开始训练了。
在线推理
训练了100步之后，我们可以先看看效果：
注意修改根目录的config.yml中的模型名称和模型名称一致：
# webui webui配置
# 注意， “:” 后需要加空格
webui: # 推理设备 device: "cuda" # 模型路径 model: "models/G_100.pth" # 配置文件路径 config_path: "configs/config.json" # 端口号 port: 7860 # 是否公开部署，对外网开放 share: false # 是否开启debug模式 debug: false # 语种识别库，可选langid, fastlid language_identification_library: "langid"
这里model参数写成：models/G_100.pth
随后新建命令：
#@title 开始推理
