$ gcc --version
gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406
gccのversionを確認。
kernel headerを確認する。
$ uname -r

これはすでにinstallされていた。https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1704&target_type=deblocal
から
cuda-repo-ubuntu1704-9-0-local_9.0.176-1_amd64.deb
をdownloadする。
$ sudo dpkg -i cuda-repo-ubuntu1704-9-0-local_9.0.176-1_amd64.deb
$ sudo apt-key add /var/cuda-repo-9.0-local/7fa2af80.pub
$ sudo apt-get update
$ sudo apt-get install cuda
sampleを試します。
$ /usr/local/cuda/bin/cuda-install-samples-9.0.sh /home/hogehoge(適当なところ)
$ cd NVIDIA_CUDA-9.0_Samples
$ makeかなり時間かかります
