安装diff-gaussian-rasterzation报错

Question

3DGS相关项目已经跑通，但是最近突然出现段错误，询问chatgpt说污染了底层内核，让我重装conda环境。不知道会不会有这个影响。在重装conda过程中使用requirements.txt安装diff-gaussian-rasterzation和simple-knn一直报错.在原项目路径里安装又报了段错误和每次都不同的错误。所以重建了文件夹重新拉取了源代码再重新建了conda虚拟环境。仍然报错如下：

再运行一次又报不同的错

尝试降级setuptools为57.5.0仍然报错

```bash
File "/home/xxx/miniconda3/envs/gs/lib/python3.9/enum.py", line 12, in _is_descriptor
          def _is_descriptor(obj):

问题分析

你遇到的问题是安装 diff-gaussian-rasterzation 时出现了段错误，之前的 3DGS 项目已经跑通，但是在重装 Conda 环境后仍然出现了问题。

解决方案

1. 检查环境: 确保你的 Conda 环境已经重装完成，并且所有依赖包都已经安装。
2. 检查 requirements.txt: 确保 requirements.txt 文件中的依赖包版本正确，并且没有任何冲突。
3. 检查 diff-gaussian-rasterzation: 检查 diff-gaussian-rasterzation 的源代码和文档，是否有任何更新或修复。
4. 尝试降级或升级: 尝试降级或升级 diff-gaussian-rasterzation 到最新或旧版本，观察是否能解决问题。
5. 检查系统环境: 检查系统环境是否有任何变化，例如系统版本、依赖包版本等。

核心代码

# 重装 Conda 环境
conda create --name myenv --file requirements.txt

# 安装 diff-gaussian-rasterzation
pip install diff-gaussian-rasterzation

注意

• 确保在重装 Conda 环境之前备份所有数据和配置。
• 如果问题仍然存在，请尝试在其他环境中安装 diff-gaussian-rasterzation，观察是否能解决问题。
