通过音频空间分解的实时神经辐射说话肖像合成。(所有文字都认识,但是拼在一起就是看不懂)
开源地址:https://github.com/ashawkey/RAD-NeRF
项目页面:https://me.kiui.moe/radnerf/
实际效果:
使用云镜像(autodl):
#1. 拉取代码仓库
git clone https://github.com/ashawkey/RAD-NeRF.git
#2. 进入项目目录
cd RAD-NeRF
#1. 创建虚拟环境
conda create --name jmaat666 python=3.10
#2. 切换环境
conda activate jmaat666
#pytorch 要单独对应cuda进行安装,要不然训练时使用不了GPU
conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia
conda install -c fvcore -c iopath -c conda-forge fvcore iopath
1. NVIDIA提供了一个命令行工具nvidia-smi,它可以显示当前系统中安装的NVIDIA驱动程序和CUDA版本信息。
nvidia-smi
2. nvcc是CUDA的编译器驱动程序,它也可以用来查看CUDA版本
nvcc --version
3. 查看CUDA安装目录:
ls /usr/local/cuda 或 ls /opt/cuda
# 测试cuda依赖是否成功安装,testCUDA.py
import torch
print(torch.cuda.is_available()) #return true
print(torch.version.cuda) #cuda version
按照CUDA对应的版本安装:https://pytorch.org/get-started/previous-versions/
#安装所需要的依赖,在RAD-NeRF目录下
pip install -r requirements.txt
# 1. 安装 pytorch3d
直接安装
pip install "git+https://github.com/facebookresearch/pytorch3d.git"
pip install "git+https://github.com/facebookresearch/pytorch3d.git@v0.7.3"
或者(推荐使用)
a.先拉取仓库地址(可以退到上一级目录操作)
git clone https://github.com/facebookresearch/pytorch3d.git
cd pytorch3d
b.查看对应的pytorch版本:https://github.com/facebookresearch/pytorch3d?tab=readme-ov-file#news
c.切换版本,并安装
git checkout v0.7.3
pip install .
# 2. 从AD-NeRF仓库,获取模型(可以退到上一级目录操作)
推荐方法:
a. 拉取仓库代码
git clone https://github.com/YudongGuo/AD-NeRF.git
b. 拷贝模型和测试视频
cp AD-NeRF/data_util/face_parsing/79999_iter.pth RAD-NeRF/data_utils/face_parsing/
cp -R AD-NeRF/data_util/face_tracking/3DMM RAD-NeRF/data_utils/face_tracking/
mkdir -p RAD-NeRF/data/obama/
cp AD-NeRF/dataset/vids/Obama.mp4 RAD-NeRF/data/obama/
或者
## 准备人脸解析模型
wget https://github.com/YudongGuo/AD-NeRF/blob/master/data_util/face_parsing/79999_iter.pth?raw=true -O data_utils/face_parsing/79999_iter.pth
## 准备basel脸部模型
从 https://faces.dmi.unibas.ch/bfm/main.php?nav=1-2&id=downloads 下载01_MorphableModel.mat放到Rad-NeRF/data_utils/face_trackong/3DMM里面。
wget https://github.com/YudongGuo/AD-NeRF/blob/master/data_util/face_tracking/3DMM/exp_info.npy?raw=true -O data_utils/face_tracking/3DMM/exp_info.npy
wget https://github.com/YudongGuo/AD-NeRF/blob/master/data_util/face_tracking/3DMM/keys_info.npy?raw=true -O data_utils/face_tracking/3DMM/keys_info.npy
wget https://github.com/YudongGuo/AD-NeRF/blob/master/data_util/face_tracking/3DMM/sub_mesh.obj?raw=true -O data_utils/face_tracking/3DMM/sub_mesh.obj
wget https://github.com/YudongGuo/AD-NeRF/blob/master/data_util/face_tracking/3DMM/topology_info.npy?raw=true -O data_utils/face_tracking/3DMM/topology_info.npy
mkdir -p data/obama/
wget https://github.com/YudongGuo/AD-NeRF/blob/master/dataset/vids/Obama.mp4?raw=true -O data/obama/obama.mp4
# 3. 下载人脸模型,并把人脸模型 01_MorphableModel.mat 放在 data_utils/face_tracking/3DMM/ 目录下
最后该目录下的文件如下:
下载人脸模型地址:https://faces.dmi.unibas.ch/bfm/main.php?nav=1-2&id=downloads
下载目录如下:
# 4. 执行convert_BFM.py文件
cd RAD-NeRF/data_utils/face_tracking
python convert_BFM.py
# 5. 返回原目录
cd ../..
#视频预处理
python data_utils/process.py data/obama/Obama.mp4
#或者 分步处理,一共有九个步骤
python data_utils/process.py data/obama/Obama.mp4 --task 1 分离音频
...
执行过程中,会下载四个模型,如果没有魔法上网,这四个模型下载很慢,或者直接下到一半就崩掉了。
模型地址:
https://download.pytorch.org/models/resnet18-5c106cde.pth
https://www.adrianbulat.com/downloads/python-fan/s3fd-619a316812.pth
https://www.adrianbulat.com/downloads/python-fan/2DFAN4-cd938726ad.zip
https://download.pytorch.org/models/alexnet-owt-7be5be79.pth
可以事先下载好4个模型,到指定的目录:
Linux:/root/.cache/torch/hub/checkpoints/

注意:
原视频很影响数字人呈现的效果(data/boama/parsing)。如果女生有头发披在身前的,可能会导致导致误判为背景,缺了一块身体。
图片分隔后,整体展示
(蓝色:人脸;绿色:脖子;红色:人身;白色:背景)
#1. 头部训练
python main.py data/obama/ --workspace trial_obama/ -O --iters 200000 #生成结果视频:trial_obama/results/ngp_ep0028.mp4
#2. 唇部训练
python main.py data/obama/ --workspace trial_obama/ -O --iters 250000 --finetune_lips #生成结果视频:trial_obama/results/ngp_ep0035.mp4
#3. 躯干训练
## <head>.pth 应该使用最新的 checkpoint in trial_obama
## 需要时间特别久(40分钟以上)
python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --head_ckpt <head>.pth --iters 200000
例:python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --head_ckpt trial_obama/checkpoints/ngp_ep0035.pth --iters 200000
# 在测试分裂上进行测试
python main.py data/obama/ --workspace trial_obama/ -O --test # 使用头部检查点,将装载GT躯干
python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --test
# GUI测试(需要window环境下)
python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --test --gui
# GUI测试 (负载语音识别模型的实时应用)(需要window环境下)
python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --test --gui --asr
# 使用特定的音频和姿势序列测试
# --test_train: 使用训练拆分进行测试
# --data_range: 使用此范围的姿势和眼睛序列(如果短于音频,自动镜像重复)
# data/intro_eo.npy 文件看第9步获取,或者用其他音频文件生成
python main.py data/obama/ --workspace trial_obama_torso/ -O --torso --test --test_train --data_range 0 100 --aud data/intro_eo.npy
注意:
1、根据不同音频生成的数字人,只有嘴型的区别,基本能对上
2、如果模型视频长度短于音频长度,将重复模型视频
3、生成出来的视频,没有音频,需要自行合并音频到视频中
9、快速体验(可以跳过训练模型,快速体验生成数字人)
下载已训练好的模型:https://drive.google.com/drive/folders/14LfowIkNdjRAD-0ezJ3JENWwY9_ytcXR
# 1. 生成音频文件npy
# 如果模型是 `<ID>_eo.pth`, 使用以下方式生成
python nerf/asr.py --wav data/aud.wav --save_feats # 生成的音频文件npy,保存到data目录下 data/<name>_eo.npy
# 如果模型是 `<ID>.pth`, 使用以下方式生成
python data_utils/deepspeech_features/extract_ds_features.py --input data/<name>.wav # save to data/<name>.npy
# 2. 生成数字人
## --pose 姿势序列文件 | --ckpt 预训练模型
python test.py --pose data/demo/obama.json --ckpt data/demo/obama_eo.pth --aud data/intro_eo.npy --workspace data/demo/trial_obama/ -O --torso
python test.py --pose data/demo/obama.json --ckpt data/demo/obama_eo.pth --aud data/aud_eo.npy --workspace data/demo/trial_obama/ -O --torso --bg_img data/demo/bg.jpg

解决方法:
#1、初始化执行环境
conda init bash
#2、如果不生效,执行一下
source ~/.bashrc
AssertionError: Torch not compiled with CUDA enabled
原因:pytorch3d安装的版本与pytorch不对应。
解决方法:
# 1.卸载pytorch3d扩展
conda uninstall pytorch3d
# 2.重新安装对应版本
参考:环境搭建-步骤5

ModuleNotFoundError: No module named 'sklearn
解决方法:安装依赖
pip install -U scikit-learn
raise AttributeError(name) from None AttributeError: _2D
解决方法:
data_utils\process.py 50行:
fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, flip_input=False)
改为:
fa = face_alignment.FaceAlignment(face_alignment.LandmarksType.TWO_D, flip_input=False)

OSError: We couldn't connect to 'https://huggingface.co' to load this file, couldn't find it in the cached files and it looks like cpierse/wav2vec2-large-xlsr-53-esperanto is not the path to a directory containing a file named config.json. Checkout your internet connection or see how to run the library in offline mode at 'https://huggingface.co/docs/transformers/installation#offline-mode'.
解决方法: 手动下载模型 https://huggingface.co/cpierse/wav2vec2-large-xlsr-53-esperanto/tree/main (全部文件),放在RAD-NeRF目录下的 cpierse/wav2vec2-large-xlsr-53-esperanto/ 目录中(需要新创建目录)
6、执行报错:python data_utils/process.py data/p/p.mp4 --task 8
torch.cuda.OutOfMemoryError: CUDA out of memory.
解决方案:
data_utils\face_tracking\face_tracker.py 180行:
batch_size = 64
改为
batch_size = 24(实际GPU的内存大小)
