雲端煉丹,算力白嫖,基於雲端GPU(Colab)使用So-vits庫製作AI特朗普演唱《國際歌》

2023-05-16 18:00:37

人工智慧AI技術早已深入到人們生活的每一個角落,君不見AI孫燕姿的歌聲此起彼伏,不絕於耳,但並不是每個人都擁有一塊N卡,沒有GPU的日子總是不好過的,但是沒關係,山人有妙計,本次我們基於Google的Colab免費雲端伺服器來搭建深度學習環境,製作AI特朗普,讓他高唱《國際歌》。

Colab(全名Colaboratory ),它是Google公司的一款基於雲端的基礎免費伺服器產品,可以在B端,也就是瀏覽器裡面編寫和執行Python程式碼,非常方便,貼心的是,Colab可以給使用者分配免費的GPU進行使用,對於沒有N卡的朋友來說,這已經遠遠超出了業界良心的範疇,簡直就是在做慈善事業。

設定Colab

Colab是基於Google雲盤的產品,我們可以將深度學習的Python指令碼、訓練好的模型、以及訓練集等資料直接存放在雲盤中,然後通過Colab執行即可。

首先存取Google雲盤:drive.google.com

隨後點選新建,選擇關聯更多應用:

接著安裝Colab即可:

至此,雲盤和Colab就關聯好了,現在我們可以新建一個指令碼檔案my_sovits.ipynb檔案,鍵入程式碼:

hello colab

隨後,按快捷鍵 ctrl + 回車,即可執行程式碼:

這裡需要注意的是,Colab使用的是基於Jupyter Notebook的ipynb格式的Python程式碼。

Jupyter Notebook是以網頁的形式開啟,可以在網頁頁面中直接編寫程式碼和執行程式碼,程式碼的執行結果也會直接在程式碼塊下顯示。如在程式設計過程中需要編寫說明檔案,可在同一個頁面中直接編寫,便於作及時的說明和解釋。

隨後設定一下顯示卡型別:

接著執行命令,檢視GPU版本:

!/usr/local/cuda/bin/nvcc --version  
  
!nvidia-smi

程式返回:

這裡建議選擇Tesla T4的顯示卡型別,效能更突出。

至此Colab就設定好了。

設定So-vits

下面我們設定so-vits環境,可以通過pip命令安裝一些基礎依賴:

!pip install pyworld==0.3.2  
!pip install numpy==1.23.5

注意jupyter語言是通過歎號來執行命令。

注意,由於不是本地環境,有的時候colab會提醒:

Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/

Successfully installed numpy-1.23.5  
WARNING: The following packages were previously imported in this runtime:  
  [numpy]  
You must restart the runtime in order to use newly installed versions.

此時numpy庫需要重啟runtime才可以匯入操作。

重啟runtime後,需要再重新安裝一次,直到系統提示依賴已經存在:

Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/  
Requirement already satisfied: numpy==1.23.5 in /usr/local/lib/python3.10/dist-packages (1.23.5)

隨後,克隆so-vits專案,並且安裝專案的依賴:

import os  
import glob  
!git clone https://github.com/effusiveperiscope/so-vits-svc -b eff-4.0  
os.chdir('/content/so-vits-svc')  
# install requirements one-at-a-time to ignore exceptions  
!cat requirements.txt | xargs -n 1 pip install --extra-index-url https://download.pytorch.org/whl/cu117  
!pip install praat-parselmouth  
!pip install ipywidgets  
!pip install huggingface_hub  
!pip install pip==23.0.1 # fix pip version for fairseq install  
!pip install fairseq==0.12.2  
!jupyter nbextension enable --py widgetsnbextension  
existing_files = glob.glob('/content/**/*.*', recursive=True)  
!pip install --upgrade protobuf==3.9.2  
!pip uninstall -y tensorflow  
!pip install tensorflow==2.11.0

安裝好依賴之後,定義一些前置工具方法:

os.chdir('/content/so-vits-svc') # force working-directory to so-vits-svc - this line is just for safety and is probably not required

這些方法可以幫助我們下載、解壓和載入模型。

音色模型下載和線上推理

接著將特朗普的音色模型和組態檔進行下載,下載地址是:

https://huggingface.co/Nardicality/so-vits-svc-4.0-models/tree/main/Trump18.5k

隨後模型檔案放到專案的models資料夾,組態檔則放入config資料夾。

接著將需要轉換的歌曲上傳到和專案平行的目錄中。

此時系統會自動在根目錄,也就是content下尋找音樂檔案,包含但不限於wav、flac、mp3等等,隨後根據下載的模型進行推理,推理之前會自動對檔案進行背景音分離以及降噪和切片等操作。

推理結束之後,會自動播放轉換後的歌曲。

結語

如果是剛開始使用Colab,預設分配的視訊記憶體是15G左右,完全可以勝任大多數訓練和推理任務,但是如果經常用它掛機運算,能分配到的顯示卡設定就會漸進式地降低,如果需要長時間並且相對穩定的GPU資源,還是需要付費訂閱Colab pro服務,另外Google雲盤的免費使用空間也是15G,如果模型下多了,導致雲盤空間不足,執行程式碼也會報錯,所以最好定期清理Google雲盤,以此保證深度學習任務的正常執行。
