排查错因：
（1）想通过输入which nvcc的方式来查询当前cuda的路径，结果没有输出任何内容。
（2）想通过输入nvcc -V的方式查看cuda版本，结果输出是：

nvcc -V
Command 'nvcc' not found, but can be installed with:
apt install nvidia-cuda-toolkit
Please ask your administrator.

（3）输入ls /usr/local | grep cuda，想要查看系统中是否有 CUDA 相关文件，输出结果为：

cuda
cuda-12
cuda-12.9

并没有预期的cuda 11.8。GPT说若输出类似cuda或cuda-11.8，说明 CUDA 已安装但未配置环境变量。若没有输出，说明 CUDA 未安装。
需要安装CUDA。

解决方案
去官网找CUDA 11.8 安装包：https://developer.nvidia.com/cuda-toolkit-archive
在这里插入图片描述
运行命令：
wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run
随后为安装程序添加执行权限。但因为我没有管理员权限，所以选择使用 --silent 静默安装，并指定 --toolkit 只安装工具链。

# 为安装程序添加执行权限
chmod +x cuda_11.8.0_520.61.05_linux.run

# 使用 --silent 静默安装，并指定 --toolkit 只安装工具链
./cuda_11.8.0_520.61.05_linux.run \
  --silent \
  --toolkit \
  --toolkitpath=$HOME/cuda-11.8 \
  --override

然后配置环境变量，这里有两种配置方式，一种是暂时的，一种是永久的。推荐使用永久的。
永久的：

echo 'export PATH=$HOME/cuda-11.8/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=$HOME/cuda-11.8/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc

暂时的（只在当前终端有效）：

export PATH=$HOME/cuda-11.8/bin:$PATH
export LD_LIBRARY_PATH=$HOME/cuda-11.8/lib64:$LD_LIBRARY_PATH

配置完成后再输入nvcc -V，就能看到版本信息了（cuda 11.8）。因此推测一开始检测到的CUDA version (12.9)是系统的cuda版本，不是当前环境中的，因此造成了冲突。此时，运行pip install -e gaussian-splatting/submodules/diff-gaussian-rasterization/也不会再报同样的错误。

二、error – unsupported GNU version! gcc versions later than 11 are not supported!

运行pip install -e gaussian-splatting/submodules/diff-gaussian-rasterization/的时候出现以下报错：

    error: command '/mnt/disk2/zijie.zheng/cuda-11.8/bin/nvcc' failed with exit code 1

报错原因：
这个报错是GCC版本和CUDA的兼容性问题有关。CUDA 11.8 使用的是基于 GCC 9.x 或 GCC 10.x 的兼容性最好的编译器版本。如果你系统默认的 GCC 是 11 或更高（特别是 12+），就会引发这种兼容性错误。
我们的系统GCC版是13.3.0，因此发生报错。

解决方法：
主要思路是在没有管理员权限的情况下降低GCC版本，试了好几种方法，下面这种方法成功了。
（1）激活当前的 Conda 环境：conda activate PhysGaussian
（2）安装 GCC 9：conda install -c conda-forge gcc_linux-64=9 gxx_linux-64=9
（3）设置环境变量让 Python/CUDA 使用这个 GCC：

export CC=$CONDA_PREFIX/bin/x86_64-conda-linux-gnu-gcc
export CXX=$CONDA_PREFIX/bin/x86_64-conda-linux-gnu-g++

（4）验证 GCC 版本：$CC --version
验证结果如下，表示安装成功：

x86_64-conda-linux-gnu-cc (conda-forge gcc 9.5.0-19) 9.5.0
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

（5）重新运行命令：pip install -e gaussian-splatting/submodules/diff-gaussian-rasterization/

三、Unknown encoder ‘libx264’

运行命令python gs_simulation.py --model_path ./model/ficus_whitebg-trained/ --output_path output --config ./config/ficus_config.json --render_img --compile_video --white_bg的时候出现报错。
报错内容：主要是最后一行Unknown encoder ‘libx264’

Unknown encoder 'libx264'

报错原因：这意味着 ffmpeg 没有编译 libx264 支持，因此无法使用 libx264 编码器导出 .mp4 等常见格式视频。
解决方法：
用conda list查看了一下当前ffmpeg的版本为 4.3，升级到指定版本4.3.1就行。

conda install -c conda-forge ffmpeg=4.3.1

安装后可用ffmpeg -encoders | grep libx264检查libx264是否可用。
PS：不要用conda install -c conda-forge ffmpeg，没有指定版本，一下子把ffmpeg的版本号升级到7.几，环境里的包出现了各种不兼容情况，一下子乱成一锅粥TvT。

四、下载速度太慢、无法递归下载项目

使用readme文件中给的方法下载速度太慢了。

git clone --recurse-submodules git@github.com:XPandora/PhysGaussian.git

使用了代理后下载速度还是很慢，发现是因为没有使用http协议，于是换成了http协议，下载速度明显变快。
但“–recurse-submodules”并没有起作用，项目中引用的一些其他项目并不能被下载下来。所以只能手动下载并添加到对应路径中去了。
