i found that the version of VS2019 may have to be lower than 16.11

[cx-zzz]

i tried to install nvdiffrec on my computer and failed when the version of VS was 16.11, and it worked when i reinstall VS2019 16.9.4
the fail was like "ninja -v "and" missing a '(' "

Thank you very much for pointing it out. Thanks to you I could at least make it work

Just tried with 16.9.4 as suggested, same error "Underlying buffer has been detached". I made sure to use the developer command prompt for this revision and also removed vs 16.11.x.

EDIT: Actually, 16.9.4 seems to work, but I had to set env variable
set DISTUTILS_USE_SDK=1

You can see a message about it in the stack trace. I had set this using other VS versions and it never worked, but now using 16.9.4 and setting that env variable, it built

If you change the _run_ninja_build in cpp_extension.py (in your_env/Lib/site-packages/torch/utils), just change it back, it may work.
The code need to be：
command = ['ninja', '-v']
if this does not work , you may ask this question in tinycuda page .

This unblocked me as well - thank you.

Thank you very much for your help, and I would like to ask what happened to the OPenSSL error when pulling from git? Can you give me some help?

[zhangzhenfengjy]

我尝试在我的计算机上安装 nvdiffrec 并且在 VS 版本为 16.11 时失败，当我重新安装 VS2019 16.9.4 时它工作 失败就像“ninja -v”和“缺少一个 '('”

How did you solve this problem? Thank you very much for your help, I can offer you some compensation.

看id是拼音就用中文了，这个错是我用16.11的时候报的，我换成16.9之后就很顺利安装好了

You need to install the latest CUDA version (11.7) + add the correct environment variables, that solved the problem for me.

Check this out, scroll down until you find the part with 11.7 instructions:

NVlabs/tiny-cuda-nn#110

I had problems and did the tips posted here (install cuda 11.7, vstudio 167.9.4) but even doing that id didnt work.
I found that I was running the wrong developer command from visual studio. If you still have problems try pasting this command on your prompt and try again

"c:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
