[리눅스] 딥러닝 컴퓨터 환경 설정

1. Ubuntu 설치 (완료)
2. Conda 설치 (완료)
3. cuda toolkit 설치 (완료)
   1. sudo apt install nvidia-cuda-toolkit

   2. cuda version 확인: nvcc -V ⇒ release 11.5

       nvcc: NVIDIA (R) Cuda compiler driver
       Copyright (c) 2005-2021 NVIDIA Corporation
       Built on Thu_Nov_18_09:45:30_PST_2021
       Cuda compilation tools, release 11.5, V11.5.119
       Build cuda_11.5.r11.5/compiler.30672275_0
      

4. GPU 연결하기 (완료)
   1. 시스템에 설치할 수 있는 Nvidia 그래픽 드라이버 목록을 확인

   2. sudo ubuntu-drivers list

       nvidia-driver-525-open, (kernel modules provided by linux-modules-nvidia-525-open-generic-hwe-22.04)
       nvidia-driver-525, (kernel modules provided by linux-modules-nvidia-525-generic-hwe-22.04)
       nvidia-driver-535-server, (kernel modules provided by linux-modules-nvidia-535-server-generic-hwe-22.04)
       nvidia-driver-470-server, (kernel modules provided by linux-modules-nvidia-470-server-generic-hwe-22.04)
       nvidia-driver-525-server, (kernel modules provided by linux-modules-nvidia-525-server-generic-hwe-22.04)
       nvidia-driver-470, (kernel modules provided by linux-modules-nvidia-470-generic-hwe-22.04)
       nvidia-driver-535, (kernel modules provided by linux-modules-nvidia-535-generic-hwe-22.04)
       nvidia-driver-535-server-open, (kernel modules provided by linux-modules-nvidia-535-server-open-generic-hwe-22.04)
       nvidia-driver-535-open, (kernel modules provided by linux-modules-nvidia-535-open-generic-hwe-22.04)
      

   3. 버전 535 설치 sudo apt install nvidia-driver-535
   4. 드라이버 설치가 완료되면 시스템을 다시 부팅한다 sudo reboot

   5. 부팅 후, Nvidia 그래픽 드라이버가 올바르게 작동하는지 확인, 설치된 드라이버 확인 nvidia-smi
