Install CUDA 10 on Ubuntu

1. Download cuda sdk from: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1810&target_type=deblocal
2. On terminal run the following at the download directory.

   sudo dpkg -i cuda-repo-ubuntu1810-10-1-local-10.1.105-418.39_1.0-1_amd64.deb
   sudo apt-key add /var/cuda-repo-10-1-local-10.1.105-418.39/7fa2af80.pub
   sudo apt-get update
   sudo apt-get install cuda

3. CUDA should be installed in:

   /usr/local/cuda-10.1

   With a soft link: /usr/loca/cuda->cuda-10.1

4. Put the following into your PATH

   export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
   export LD_LIBRARY_PATH=/usr/local/cuda/lib64:${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

5. Verify with samples:

   cp -r /usr/local/cuda/samples ~/cuda_samples
   cd ~/cuda_samples/1_Utilities/deviceQuery
   make
   ./deviceQuery

   You should see your GPU info printed.
