#!/bin/bash

### steps ####
# verify the system has a cuda-capable gpu
# download and install the nvidia cuda toolkit and cudnn
# setup environmental variables
# verify the installation
###

### to verify your gpu is cuda enable check
lspci | grep -i nvidia

### 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*

# 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
sudo apt update

# install nvidia driver with dependencies
sudo apt install libnvidia-common-515
sudo apt install libnvidia-gl-515
sudo apt install nvidia-driver-515

# copy the following files into the cuda toolkit directory.
sudo cp -P cuda/include/cudnn.h /usr/local/cuda-11.7/include
sudo cp -P cuda/lib/libcudnn* /usr/local/cuda-11.7/lib64/
sudo chmod a+r /usr/local/cuda-11.7/lib64/libcudnn*

# Finally, to verify the installation, check
nvidia-smi
nvcc -V

# install Pytorch (an open source machine learning framework)
pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu117

Thanks a lot for making the shell script. I am also running into a dependency issue, however. Any fix for this? sudo apt install libnvidia-compute-515 is already part of the script, so that doesn't help. Tried 535 as well
The following packages have unmet dependencies:
cuda-11-7 : Depends: cuda-runtime-11-7 (>= 11.7.1) but it is not going to be installed
Depends: cuda-demo-suite-11-7 (>= 11.7.91) but it is not going to be installed

@primus852 @fatbringer @ichxw @qburst-fidha Did you guys get this figured out?

Although the above suggestions did not work for me, I found that the runfile installation from the nvidia website, rather than the apt-get installation does work. Maybe this helps someone else!

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*

Reboot
