[230302] ubuntu에 cudnn 설치

[cudnn 설치]

1. nvidia-smi 설치
   (*recommended 버전 확인)

ubuntu-drivers devices

sudo apt install -y nvidia-driver-470

(재부팅)

nvidia-smi

2. cuda-toolkit 설치

wget https://developer.download.nvidia.com/compute/cuda/11.4.0/local_installers/cuda_11.4.0_470.42.01_linux.run

sudo sh cuda_11.4.0_470.42.01_linux.run

(재부팅)

(*폴더명 확인)
ls -lh /usr/local | grep cuda​

(*환경변수 추가)
export PATH=$PATH:/usr/local/cuda-11.4/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.4/lib64

export CUDADIR=/usr/local/cuda-11.4​

source /etc/profile

(*설치확인)
nvcc -V
