install cuda 8 and cudnn 5 1 with correct procedure in linuxmint and ubantu

compile cuda samples visit this site https://www.pugetsystems.com/labs/hpc/NVIDIA-DIGITS-Install-783/ for creating custum os iso go to this site with all drivers software installed to remove a directory in root use the command $ rm -r directory folder name https://www.youtube.com/watch?v=EzFchFGJhfc for cuda 8 and cudnn5.1 correct installation go to this site https://github.com/09rohanchopra/kerai-labs/blob/master/Getting%20Started.ipynb https://www.youtube.com/watch?v=yDIKSykkgOk after istallation $ gedit ~/.bashrc paste the commands below and continue and save it by $ source ~/.bashrc Make sure that your NVIDIA GPU is properly configured beforehand. nvcc should be in the PATH. If not, something like this should do the job: https://github.com/philipperemy/yolo-9000 export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}} export PATH=/usr/local/cuda-8.0/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH Let's now compile darknet with GPU support! in ubantu 18.04 or 16.04 or 17.04 or 17.10 this error shows do the below ***************************************************************** error -- unsupported GNU version! gcc versions later than 6 are not supported! ****************************************************************** For CUDA 9: sudo apt install gcc-6 g++-6 sudo ln -s /usr/bin/gcc-6 /usr/local/cuda/bin/gcc sudo ln -s /usr/bin/g++-6 /usr/local/cuda/bin/g++ For CUDA 8: sudo apt install gcc-5 g++-5 sudo ln -s /usr/bin/gcc-5 /usr/local/cuda/bin/gcc sudo ln -s /usr/bin/g++-5 /usr/local/cuda/bin/g++ For CUDA7.5 these lines work: sudo ln -s /usr/bin/gcc-4.9 /usr/local/cuda/bin/gcc sudo ln -s /usr/bin/g++-4.9 /usr/local/cuda/bin/g++ for further clarfication on above error visit this site https://stackoverflow.com/questions/6622454/cuda-incompatible-with-my-gcc-version
