error about SIBR_viewer

[Bo Xu]

hello, it's an excellent work. However, when I compile the render tools in the SIBR_viewer, I encounter a problem that I can not find the torch. Do you know how I can solve this problem? Thank you so much.

[Kerui Ren]

You need to download and configure libtorch(1.10) and choose the correct version according to your build mode (Debug or Release).

[Kerui Ren]

After downloading, compile according to the following process https://github.com/city-super/Scaffold-GS/tree/main/SIBR_viewers

[Bo Xu]

Thanks, are there instructions for Linux? Because I am not familiar with windows.

[Bo Xu]

When I run the original Gaussian Splatting, there is no similar problem. So I think the problem may be the Cmakelists?

[Kerui Ren]

Due to equipment reasons, we have not compiled it in linux before, but we will improve the Linux instructions in the near future.

[Kerui Ren]

Also, we figure out the cause of the problem. We'll work it out as soon as possible.

Hello! have you already figure out the linux version? I meet the same problem, and I've tried for a long time.

I met the same error and this could be solved appropriately using this compile command:

Torch_DIR=`python -c 'import torch;print(torch.utils.cmake_prefix_path)'` cmake -Bbuild . -DCMAKE_BUILD_TYPE=Release

if you have installed the pytorch package.

I encounter another problem that:

undefined reference to `cv::imread(std::string const&, int)'

I compiler this viewer using the following Dockerfile:

ARG OS_VERSION=22.04
#编译viewers的时候需要使用CUDNN
ARG CUDNN_VERSION=8

You can try to add -D_GLIBCXX_USE_CXX11_ABI=1 or -D_GLIBCXX_USE_CXX11_ABI=0 to your command.

[SiN]

You can try to add -D_GLIBCXX_USE_CXX11_ABI=1 or -D_GLIBCXX_USE_CXX11_ABI=0 to your command.

I tried both options, but neither worked. Additionally, when I added the option, the following warning appeared:

CMake Warning:
