Install CUDA 10.1 in Ubuntu 18.04
Pytorch를 사용해야해서 CUDA 10.1를 설치해야했는데, CUDA 공식 사이트의 다운로드 페이지에서 나와있는 설명으로 따라해도 번번히 실패를 하곤 해서 구글링을 통해 해결하였다.
도움은 깃허브 이곳[gist.github.com/Mahedi-61/2a2f1579d4271717d421065168ce6a73#file-cuda_10-1_installation_on_ubuntu_18-04-L6] 에서 받았고, 후에 사용해야해서 기록을 위해 적어놓는다.
### steps ###
# verity the system has a cuda-capable gpu
# download and install the nvidia cuda toolkit and cudnn
# setup environmental variables
# verify the installation
###
### If you have previous installation remove it first.
sudo apt-get purge nvidia*
sudo apt remove nvidia-*
sudo rm /etc/apt/sources.list.d./cuda*
sudo apt-get autoremove && sudo apt-get autoclean
sudo rm -rf /usr/local/cuda*
### to verify your gpu is cuda enable check
lspci | grep -i nvidia
### gcc compiler is required for development using the cuda toolkit. to verify the version of gcc install enter
gcc --version
# system update
sudo apt-get update
sudo apt-get upgrade
# install other import packages
sudo apt-get install g++ freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libglu1-mesa libglu1-mesa-dev
# first get the PPA repository driver
sudo add-apt-repository ppa:graphics-drivers/ppa

# install cuDNN v7.6
# in order to download cuDNN you have to be regeistered here https://developer.nvidia.com/developer-program/signup
# then download cuDNN v7.6 form https://developer.nvidia.com/cudnn
CUDNN_TAR_FILE="cudnn-10.1-linux-x64-v7.6.5.32.tgz"
tar -xzvf ${CUDNN_TAR_FILE}
# copy the following files into the cuda toolkit directory.
sudo cp -P cuda/include/cudnn.h /usr/local/cuda-10.1/include
sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda-10.1/lib64/
sudo chmod a+r /usr/local/cuda-10.1/lib64/libcudnn*
# Finally, to verify the installation, check
nvidia-smi
nvcc -V
