Install Environment Question

[yoowy90]

I try to install this but there are a lot of issues during install other libraries ex. torch and cuda version dependency, colmap, multi-view evaluation tool I think that is because versions of ubuntu, cuda, etc... are different. Can you tell me detail install environments??

Our code is tested on the machine with ubuntu 18.04, and CUDA version is 11.7. We have tested it on other machines such as ubuntu 20.04 and CUDA 11.3, 10.2, etc., and the code also works well.

I used the same version （11.7），but your modified colmap seemingly requires 11.8 at least. Can you help me? Thanks! @hxy-123

3090. I uninstalled gcc11.4 and used gcc 9.4 to replace it, this issue has been fixed. @hypochlorous

Can I use a different pytorch version from 1.8.0? 1.8.0 does not have precompiled binary with CUDA=11.7. Or do I have to compile pytorch myself?

The overall repo doesn't have specific dependencies of pytorch version. I think you can feel free to try to use other pytorch versions.
