cuDNN 설치 방법

• https://developer.nvidia.com/cudnn
• 우분투라고 할지라도, Tar 리눅스를 다운 받아라! (훨씬 쉽대)
• 다운 받은 경로로 가서, 아래 명령어 실시!

# 압축 풀기, 압축을 풀면 archive로 끝나는 폴더가 생성된다.
tar -xvf cudnn-linux-x86_64-X.X.X.XX_cuda11-archive.tar.xz

# 아래부터는 파일을 cuda에 복사하기
sudo cp cudnn-*-archive/include/cudnn*.h /usr/local/cuda/include 
sudo cp -P cudnn-*-archive/lib/libcudnn* /usr/local/cuda/lib64 
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

# cuda 디렉토리와 실제 설치된 cuda-11.8 디렉토리를 심볼릭 링크 설정해준다.

설치 확인

• sudo ldconfig
• ldconfig -N -v $(sed 's/:/ /' <<< $LD_LIBRARY_PATH) 2>/dev/null | grep libcudnn
