关于环境配置的问题

[mar21-svg]

作者您好，抱歉打扰了。首先十分感谢您代码的开源。但是我在尝试复现的过程中，装配环境总是会出问题。我完全按照您的readme文档安装，在执行conda env create --file environment.yml时，出现了如下报错，尝试了很多方法均没能解决，想向您请教这里该如何处理呢？
十分感谢！

你好，可能是torch安装的问题，可以试试用pip安装而不是conda。可以参考这个repo来安装环境，大部分package是一样的。

[mar21-svg]

作者您好，感谢您的建议，我现在每一步都用pip安装，torch相关也安装的是pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116，并一步一步安装了所有的依赖，但是安装子模块pip install -e r2_gaussian/submodules/simple-knn时，依然出现了这样的报错，尝试了很久也未能解决。想请教您有没有什么其他的解决方案呢？十分感谢！

作者您好，我尝试安装了您推荐的那个repo，但是在执行到
git clone https://github.com/CERN/TIGRE.git
cd TIGRE
pip install .
时，似乎也出现了类似的报错，想向您请教一下。如果您有时间的话可以麻烦指点一二吗？感激不尽！

根据gpt的解答，似乎是编译器的问题。

From GPT:

你在用 32-bit（x86）工具链去编译 CUDA 扩展，而 CUDA/VS 的头文件和汇编内联都是按 64-bit（x64） 设计的，所以出现了 size_t 重定义、type_traits 模板重复定义、asm operand type size(8) 不匹配等一串级联错误。关键信号：

构建目标目录是 build\lib.win32-cpython-38\...（win32 = 32 位）。

MSVC 调用的是 ...bin\HostX86\x86\cl.exe（明确是 x86 编译器）。

NVCC 报错堆栈里到处是 “first parameter of allocation function must be of type size_t”、_alloca C linkage 冲突、以及 sm_32/20 intrinsic 的尺寸不匹配——这些都是用 x86 主机编译器/ABI 去编 64-bit 期望代码的典型现象。

作者您好，十分感谢您的指点，现在您的r2_gaussian的环境都已经完成安装，感激不尽！！！
之前遇到了很多问题，有win-32和win-64的不匹配，有VS编译器版本和CUDA版本不匹配，有CUDA编译器找不到xray子模块中backward.cu、forward.cu程序中的M_PI（在 Windows + MSVC 环境下，默认不开启 POSIX 数学常量支持，所以 M_PI 未定义。）
对遇到的问题稍作记录，如果未来有人遇到同样的问题，希望能有些许借鉴意义。
再次感谢作者的开源代码和无私帮助！祝作者同志身体健康，工作顺利！
