Hey, it seems that you are building on Windows. This is currently not supported (only linux). However, you can try if this helps: #4

Other have reported to run it under WSL.
Hope this helps!

[MrNeRF]

Solved for you?

[kenculate]

I will test on wsl and comment here the result

I spent a few hours trying to install cuda toolkit 11.8 or higher, it is installed now but still there is error

[MrNeRF]

The error says that it only finds cuda 11.5. So you either have to update the LD_LIBRARY_PATH properly (assuming that your installation is correct) or you can try to edit the CMakeLists.txt and set the requirement to 11.5 (untested). For the first option please follow the cuda Installation guide that NVIDIA provides. It is straight forward but you may not leave any steps out!

[kenculate]

I have completely removed all cuda, and installed using this link

Here you go. It clearly states what is going on . Something seems wrong with your CUDA installation. It is akward that it is located within a anaconda path.
I would change those lines to 11.5 and see what happens:

well I start a fresh wsl, and start installing from scratch, after installing bunch of missing dependencies, I got this error

Looks good to me. Its killed. You should maybe build with fewer cpus

[kenculate]

there is 2 error at the end and this file is not being generated
$ ./build/gaussian_splatting_cuda -d /path/to/data -o /path/to/output -i 1000

[MrNeRF]

What hardware (gpu) do you use? Compute capability 86 -> 3080, 3090?
Not sure, what the problem is as I cannot investigate it myself.

[kenculate]

Processor AMD Ryzen 7 5800X
GPU NVIDIA GeForce RTX 3090

[MrNeRF]

In theory it should work and there are people who have made it work. However, as I don't support windows for now and I do not have a win installation on my computer, there is little I can do about it. That might change in the future. I'll close this issue since I won't investigate it further. If you figured it out, you are invited to post a installation guide.

[molegod]

@kenculate Did you ever get this working?

[saeid-gholizade-pxo]

I can't remember, but probably stopped trying!
