单图换脸roop源码与环境配置

前言

1.roop是新开源了一个单图就可以进行视频换脸的项目,只需要一张所需面部的图像。不需要数据集,不需要训练。

2.大概的测试了一下,正脸换脸效果还不错,融合也比较自然。但如果人脸比较大,最终换出的效果可能会有些模糊。侧脸部分的幅度不宜过大,否则会出现人脸乱飘的情况。在多人场景下,也容易出现混乱。

3.使用简单,在处理单人视频和单人图像还是的换脸效果还是可以的,融合得也不错,适合制作一些小视频或单人图像。

4.效果如下:

 环境安装

1.我这里部署部署环境是win 10、cuda 11.7、cudnn 8.5、GPU是N卡的3060(6G显存),加anaconda3.

2.源码下载,如果用不了git,可以下载打包好的源码和模型。

git clone https://github.com/s0md3v/roop.git
cd roop

3.创建环境

conda create --name roop python=3.10
activate roop
conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia
pip install -r requirements.txt

4.安装onnxruntime-gpu推理库

pip install onnxruntime-gpu

5.运行程序

python run.py

运行,它会下载一个500多m的模型,国内的网可能下载得很慢,也可以单独下载之后放到roop根目录下。

7.报错

ffmpeg is not installed!

这个是缺少了FFmpeg,FFmpeg是一套可以用来记录、转换数字音频、视频,并能将其转化为流的开源计算机程序。简单说来就是我们可以用它来进行视频的编解码,可以将视频文件转化为视频流,也可以将视频流转存储为视频文件。还有一个重点就是它是开源的。去官网下载后,加到环境变量就可以了。

8.如果在本地的机子跑起来很慢,把它做成服务器的方式运行,这样就可以在网页或者以微信公众 号或者小程序的方式访问,服务器端代码:
