问题描述

按照官方教程安装nerf studio运行命令pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch安装tiny-cuda-nn时出现以下报错

× python setup.py egg_info did not run successfully.
  │ exit code: 1

      Traceback (most recent call last):

      Building PyTorch extension for tiny-cuda-nn version 1.7

根据报错出现问题的原因是找不到Visual C++编译器的位置。

解决方法

参考链接https://github.com/NVlabs/nvdiffrec/issues/35

Step1: 安装VS2019已安装可跳过

下载Visual Studio Installer

Visual Studio2019下载链接https://visualstudio.microsoft.com/zh-hans/vs/older-downloads/

本人选择的是免费的Community版本
在这里插入图片描述
勾选使用C++的桌面开发

注意如果安装的VS不是2017-2019版本会出现以下报错
#error: -- unsupported Microsoft Visual Studio version! Only the versions between 2017 and 2019 are supported!

Step2: 添加环境变量

右键此电脑->属性->高级系统设置->高级->环境变量
在这里插入图片描述
在系统变量Path中添加G:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64 按照自己的VS安装路径我的安装路径是G:\Program Files (x86)\Microsoft Visual Studio
