windows本地运行dreamtalk踩坑总结

dreamtalk是一个语音+图片转视频的一个工具,就是给一段语音加一个头像图片,然后生成一段头像跟语音对口型的视频,其实还是很有意思的,最近阿里发布了一个类似的模型,但是还没开源,从展示视频看,阿里的那个效果比dreamtalk要好,希望早日开源。

本地运行其实坑主要在安装各种依赖包上,项目地址在dreamtalk · 模型库 (modelscope.cn),可以先把代码下下来,然后就开始装依赖包,第一个依赖:dlib,dlib是c++版本的dlib的一个python绑定,但是目前windows只有py3.6的,如果你的python版本正好是这个,那就直接pip install dlib就行,如果不是,就需要本地编译,本地编译的话,需要安装cmake,可以去官网下载https://github.com/Kitware/CMake/releases/download/v3.29.2/cmake-3.29.2-windows-x86_64.msi

如果访问不了可以用把连接复制到迅雷里用迅雷下(点赞迅雷),安装的时候记得勾选添加到环境变量,cmake是比较好装的,第一软件大小比较小,第二页没什么其它的依赖,下载装上就行了,另外一个就是安装visual studio了,这个就比较大了,当然除了大,其它的也还好,只要网速快,硬盘够大,也没什么大问题。装完了这两个就能对dlib进行编译了,但是正常情况下,你装完了这个,下载了dlib源码,运行python setup.py install还是会编译失败,这时还需要添加一个参数,那就是去掉gif支持 python .\setup.py install --no DLIB_GIF_SUPPORT这样才能编译安装成功,至此,第一个依赖安装成功。

第二个依赖就是ffmpeg,这个是个命令行软件,dreamtalk主要用它来生成视频文件用,这个安装比较简单,只需要下载下来,然后把ffmpeg.exe的路径添加环境变量里就行了。

第三个依赖是ffmpeg的python绑定,叫pyav,这个比较简单,只要pip install av就行了。

第四个依赖是神经网络库torch、torchvision、torchaudio了,我安装的是cpu版,这个看个人选择,因为我只想跑个结果,所以没用gpu,这块的安装如果有问题可以自己百度一下,我就不细写了,我这遇到的问题是版本问题,查了一下彼此的匹配版本,解决了问题,我的版本

torch 1.10.1

torchaudio 0.10.1

torchvision 0.11.2

第五个依赖是模型,dreamtalk依赖了一个叫jonatasgrosman/wav2vec2-large-xlsr-53-english的项目,这个项目托管在huggingface,需要翻墙,本来这个依赖代码里有自动下载代码,但是网络不通,下载时会报错,怎么办,百度搜到了一个镜像站HF-Mirror - Huggingface 镜像站,然后配置一个环境变量名字为HF_ENDPOINT,值就是镜像站首页地址,然后运行启动文件,文件也正常开始下载,但是不知道为什么,下了一部分的时候,就会报远程主机关闭连接的错误,可能是带宽问题,也可能是我电脑ip问题,如果屏幕前的你可以正常下那就再好不过,可惜我这自动下是不可能了,所以我就只能手动下,结果没想到手动也是报错,关键时刻,还是迅雷好使,连接一复制,非常快的就下载下来了(再次点赞迅雷)。下载好项目后,重点来了,需要把项目放到dreamtalk根目录下,并且外边还要包一层jonatasgrosman目录,因为代码引用就是这个结构,所以要注意。

其它python依赖,安装很简单,放个截图

经历了5大依赖,近两天的折腾,本以为就要可以跑一下了,结果运行启动文件,又报错了,错误是关于cuda的,因为我装个的cpu版本的torch是不支持cuda的,所以需要把cuda的代码删掉,于是,我小心翼翼,删掉了调用cuda()函数的代码,终于是可以运行了。修改后的代码inference_for_demo_video.py

印象里就这两个文件,当然如果你装的gpu版本的torch,不需要改代码。 效果图,说的是你好,你会写代码吗

总结来说,跑一个开源项目还是不太容易的,这还是不用写代码的情况,特别是第一次,之前什么都没装,跑起来可是真麻烦,我一度怀疑能跑起来,好在没放弃,搞了两天终于搞出来,记录一下,有需要的朋友可以参考一下,有什么问题也可以随时给我留言。
