nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'

I've looked at many pages and either could not follow what they were saying because they were unclear and/or my knowledge is just not sufficient enough.

I am trying to run:

luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec

So that I may run DenseCap over some images using GPU Acceleration. When I run it, I get this error:

$ luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec

I was able to luarocks install cutorch, luarocks install cunn, and luarocks install cudnn just fine.

I am running Ubuntu 16.04 on a GTX 1080ti.

For some reason, when I run $ nvcc -V, I get:

    The program 'nvcc' is currently not installed. You can install it by typing:
sudo apt install nvidia-cuda-toolkit

..and this is another big problem I am facing. When I install nvcc, it installs the toolkit for Cuda 7.5, but I have Cuda 9.0. I installed it using the .deb file that comes from Cuda's website.

$ sudo apt-get install cuda

cuda is already the newest version (9.0.176-1).

  nvidia-profiler nvidia-visual-profiler opencl-headers
Use 'sudo apt autoremove' to remove them.

I honestly expect that I need to install nvcc, but like I said, it installs for the wrong version, and I cannot for the life of me figure out how to install it for the right version, and Im really confused as to why I am getting this error now even though I already installed cutorch, cudnn, and cunn just fine. Any help is appreciated...

Thanks

Try to change the code architecture (such as sm_20) to some higher version in CMakeLists.txt of stnbhwd that you are trying to install.

From:

IF (CUDA_FOUND)
   LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_20")

to:

IF (CUDA_FOUND)
   LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_30")
