本案例通过Deep3DFaceRecon_pytorch实现

本文是在本地没有gpu硬件的支持下的实现方案，并不具体描述部署过程，部署过程建议看上面两个文档地址

准备工程文件

将下载好的Deep3DFaceRecon_pytorch工程文件（详见https://blog.csdn.net/flyfish1986/article/details/121861086中百度网盘的地址）

解压到本地（这个工程已经包含20epoch模型，不用再去谷歌网盘下载了）

项目根目录创建environment.sh

apt-get update && apt-get install -y --no-install-recommends 
    pkg-config 
    libglvnd0 
    libgl1 
    libglx0 
    libegl1 
    libgles2 
    libglvnd-dev 
    libgl1-mesa-dev 
    libegl1-mesa-dev 
    libgles2-mesa-dev 
    cmake 
    curl 
    libsm6 
    libxext6 
    libxrender-dev

cp docker/10_nvidia.json /usr/share/glvnd/egl_vendor.d/10_nvidia.json

pip install --upgrade pip
pip install ninja imageio imageio-ffmpeg

pip install ninja -i https://pypi.douban.com/simple

这一步主要是初始化环境，包含：安装python库等

修改文件util/nvdiffrast.py：

# if self.glctx is None:
# self.glctx = dr.RasterizeGLContext(device=device)
# print("create glctx on device cuda:%d"%device.index)
if self.glctx is None:
    self.glctx = dr.RasterizeCudaContext(device=device)
    print("create glctx on device cuda:%d"%device.index)

这一步需要将OpenGL的依赖替换为cuda的，不然会报错：https://github.com/sicxu/Deep3DFaceRecon_pytorch/issues/81#issuecomment-1918455559
