기존에 설치되어 있는 것들 제거. Ubuntu 20.04에는 기본으로 Nvidia Driver가 설치되어 있으므로 이를 지워주어야 함.

$ sudo apt-get purge nvidia*
$ sudo apt-get autoremove
$ sudo apt-get autoclean

CUDA 설치

1. 레포지토리 키 등록

$ sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/7fa2af80.pub

2. apt에 레포지토리 주소 등록

$ sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64 /" >> /etc/apt/sources.list.d/cuda.list'
$ sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /" >> /etc/apt/sources.list.d/cuda.list'

3. CUDA, Nvidia Driver 설치 (CUDA를 설치하면 자동으로 이에 의존된 드라이버 자동으로 설치)

$ sudo apt update
$ sudo apt install cuda
$ sudo apt install cuda-10-1

4. cuDNN 설치를 위한 repo 패키지 설치

$ wget http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu2004/x86_64/nvidia-machine-learning-repo-ubuntu2004_1.0.0-1_amd64.deb
$ sudo dpkg -i nvidia-machine-learning-repo-ubuntu2004_1.0.0-1_amd64.deb

5. cuDNN 레포지토리 추가

$ sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /" >> /etc/apt/sources.list.d/nvidia-machine-learning.list'

6. cuDNN 설치 (CUDA 버전에 맞는 버전으로 설치해야 함)

$ sudo apt install libcudnn7-dev=7.6.5.32-1+cuda10.1 libcudnn7=7.6.5.32-1+cuda10.1

추후 업데이트시 최신버전으로 업데이트 되는 것을 방지

$ sudo apt-mark hold libcudnn7 libcudnn7-dev
libcudnn7 set on hold.
libcudnn7-dev set on hold.

이와 같이 설치를 완료하고, 재부팅한 다음… 드라이버가 잘 설치되어 있는지 확인

$ nvidia-smi

---

TensorFlow2 설치

$ sudo apt install python3-pip
$ sudo pip3 install -U tensorflow-gpu

환경변수 셋업

$ echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.1/lib64:/usr/local/cuda-10.2/lib64:/usr/local/cuda-10.1/lib64' >> ~/.bashrc
$ source ~/.bashrc

실행 및 설치 확인
