Error in installation

run this line:
pip install --global-option="--no-networks" git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch

then get this error :

As noted in our installation instructions, we require Visual Studio to build tiny-cuda-nn.
From the log above, it seems VS is not found in your env.

raise RuntimeError("Could not locate a supported Microsoft Visual C++ installation")
RuntimeError: Could not locate a supported Microsoft Visual C++ installation

If the error persists, I would suggest reporting that issue there https://github.com/NVlabs/tiny-cuda-nn, or testing their bindings in isolation to track down the issue: https://github.com/NVlabs/tiny-cuda-nn#pytorch-extension

@rezanit76 you need to install the vs_build_tools download, which will setup a supported Microsoft Visual C++ installation.
That should be enough to fix that error. That's how I fixed it.

I´ve got the same error. In the TinyCuda documentations they suggest to install Visual Studio Code, C++ complements, and at least run "helloWorld".
However, I kept getting the error: "Could not locate a supported Microsoft Visual C++ installation".

What worked for me instantly was to add in PATH the location of "cl.exe". It is embedded in the installation of Microsoft Visual Studio (probably Visual Studio Code is not a must, but I'm not sure).
In Windows, go to System Properties >> Advanced system settings >> Advanced (tab) >> Environment variables >> PATH (edit) >> here I've added a new line with:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.32.31326\bin\Hostx64\x64
This is the location of "cl.exe" which is the C++ compiler.

I've had to add several variables in PATH.
Just for the record this is my entire PATH:
C:\Program Files\Git\bin;C:\Program Files\Git\cmd;C:\Users\jpyunda\Documents\Nvidia CUDA docs\zlib123dllx64;C:\Program Files\NVIDIA\CUDNN\v 8.4.1.50;C:\Program Files\CMake\bin;C:\Users\jpyunda\AppData\Local\Programs\Microsoft VS Code\bin;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.32.31326\bin\Hostx64\x64;

see this #29 (comment)

worked for me

I re-downloaded vs2022 and installed it in the default location (drive C), which has been solved

[Lanson426]

@rezanit76您需要安装 vs_build_tools 下载，它将设置受支持的 Microsoft Visual C++ 安装。 这应该足以修复该错误。我就是这样修好的。

it worked for me

这是在寻找cl.exe文件，假如你的VS安装在D盘你需要需修改setup文件
