Installing cuda and cudnn in ubuntu 20.04 [duplicate]
Ubuntu 18.04, CUDA 10.1, libcudnn 7.5.1 and NVIDIA 418.67 drivers
Notes
-
2021-01-07: Please use the 20.04 installation below moving forward as the steps are the same for both 18.04 and 20.04.
-
2019-06-23: Recent updates with either the CUDA 10.0 or 10.1 versions the NVIDIA 418.67 driver, that installs with it, no longer has the 32bit libraries included and this will cause Steam and most games to no longer work. The version of
libnvidia-gl-418:i386only installs the 418.56 version which will not work with the 418.67 driver. Hopefully NVIDIA will release an update for that soon. I have added the info at the bottom of this answer in the.run file installpart of how to download just the run file for the CUDA installer then you can use whatever driver you want. The run file is 2.3GB in size, so it might take a bit to download. -
CUDA 9.x is not available through NVIDIA's ubuntu1804 repo. I did however write an answer for CUDA 9.2 at https://askubuntu.com/a/1086993/231142
Installing CUDA through the repository (instead of the .deb installation)
The following lines you can copy and paste to a terminal window. Press Ctrl+Alt+T to open a terminal window.
Remove and update
Remove any CUDA PPAs that may be setup and also remove the nvidia-cuda-toolkit if installed:
sudo rm /etc/apt/sources.list.d/cuda*
sudo apt remove --autoremove nvidia-cuda-toolkit
Recommended to also remove all NVIDIA drivers before installing new drivers:
sudo apt remove --autoremove nvidia-*
Then update the system:
sudo apt update
Add and install
Recently, I just found out that the CUDA installation works with the graphics-drivers ppa so if you don't have it added, add it now:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
The install the NVIDIA driver. For this we are going to use the 440 driver
sudo apt install nvidia-driver-440
Now, install the key:
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
Add the repos:
sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /" > /etc/apt/sources.list.d/cuda.list'
sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /" > /etc/apt/sources.list.d/cuda_learn.list'
Update the system again:
sudo apt update
Install CUDA 10.1:
sudo apt install cuda-10-1
It should be installing the NVIDIA 418.40 drivers with it as those are what are listed in the repo. See: http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/
Install libcudnn7 7.5.1:
sudo apt install libcudnn7
Tune environment and reboot
Add the following lines to your ~/.profile file for CUDA 10.1
# set PATH for cuda 10.1 installation
if [ -d "/usr/local/cuda-10.1/bin/" ]; then
export PATH=/usr/local/cuda-10.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
fi
Reboot your computer.
Check your settings
Check NVIDIA Cuda Compiler with nvcc --version:

.run file install
Install driver
By using the sudo add-apt-repository ppa:graphics-drivers/ppa you can install the 430.26 newest driver or any that suit your fancy.
Install libcudnn7
Add the Repo:
sudo bash -c 'echo "deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /" > /etc/apt/sources.list.d/cuda_learn.list'
Install the key:
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
Update the system:
sudo apt update
Install libcudnn7.5.1:
sudo apt install libcudnn7
Download the .run file
Now download the cuda_10.1.105_418.39_linux.run from https://developer.nvidia.com/cuda-10.1-download-archive-base?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocal
If you want CUDA 10.2 the download instructions are here: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocal Then follow through with the same steps as below but make sure to update to 10.2 instead of 10.1.
Then run the installer:
sudo sh cuda_10.1.105_418.39_linux.run
Type in accept and press enter on this screen:

Wait for the install to finish, it might say errors during, but not to worry.
Tune environment and reboot
Add the following lines to your ~/.profile file for CUDA 10.1
# set PATH for cuda 10.1 installation
if [ -d "/usr/local/cuda-10.1/bin/" ]; then
export PATH=/usr/local/cuda-10.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
fi
Reboot the system for the changes to take effect.
Ubuntu 20.04 LTS, CUDA 11.5.0, NVIDIA 495 and libcudnn 8.0.4
I don't recommend installing the NVIDIA drivers that come with CUDA as they do not contain the dkms drivers that carry over into new kernel upgrades.
The Ubuntu repositories now contain the same drivers as the graphics-drivers PPA. So feel free to install the 495.44 drivers.
sudo apt install nvidia-driver-495
Reboot the system so the new driver takes effect.
Now, download the CUDA 11.5.0 .run file from NVIDIA:
wget https://developer.download.nvidia.com/compute/cuda/11.5.0/local_installers/cuda_11.5.0_495.29.05_linux.run
Run the .run file as sudo:
sudo sh ./cuda_11.5.0_495.29.05_linux.run
If you get the following, just choose Continue:
┌──────────────────────────────────────────────────────────────────────────────┐

│ recommended that you remove this before continuing. │

After the installation is complete add the following to the bottom of your ~/.profile or add it to the /etc/profile.d/cuda.sh file which you might have to create for all users (global):
# set PATH for cuda 11.5 installation
if [ -d "/usr/local/cuda-11.5/bin/" ]; then
export PATH=/usr/local/cuda-11.5/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.5/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
fi
Install libcudnn8
Add the Repo:
NOTE: The 20.04 repo from NVIDIA does not supply libcudnn but the 18.04 repo does and installs just fine into 20.04.
echo "deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /" | sudo tee /etc/apt/sources.list.d/cuda_learn.list
Install the key:
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
Update the system:
sudo apt update
Install libcudnn 8.0.4:
sudo apt install libcudnn8
I recommend now to reboot the system for the changes to take effect.
After it reboots check the installations:
