NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

flyingalpaca · December 18, 2020, 2:21am

Hello,
In attempts to download pytorch, I tried downgrading CUDA from 11.2 to 10.0 on Ubuntu 18.04.
This seems to have caused errors in the NVIDIA Driver.

Below are outputs from the following commands

dpkg -l | grep nvidia

nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

nvcc -V

Command 'nvcc' not found, but can be installed with:

sudo apt install nvidia-cuda-toolkit

lspci | grep -i nvidia

01:00.0 VGA compatible controller: NVIDIA Corporation GP107GL [Quadro P600] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1)

I cannot generate the nvidia-bug-report.sh as it outputs

Running nvidia-bug-report.sh...ls: cannot access '/proc/driver/nvidia/./gpus/': No such file or directory

When I checked /proc/driver/, it has no folders.

You installed the full package including drivers, which is too old for the kernel.

purge anything nvidia/cuda
add the ubuntu graphics ppa [url]https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa[/url]
install the driver from that (sudo apt install nvidia-driver-455)
download the cuda .deb
add the repo to your system
don’t install cuda
instead, run sudo apt install cuda-toolkit-10-0
set PATH variable if necessary
have nvidia-persistenced start on boot and make sure it is continuously running

Thank you for the reponse

I’ve tried to follow your steps with:

sudo apt-get purge nvidia → didn’t remove anything
sudo apt-get purge cuda → removed cuda*
sudo add-apt-repository ppa:graphics-drivers.ppa
sudo apt-get update

They all ran fine without errors

However, when I tried to run:
sudo apt install nvidia-driver-455

It comes up with the following error:

Is there a way to fix this?

Thank you!

generix · December 22, 2020, 8:52am

To remove the driver, try

sudo dpkg -P $(dpkg -l | grep nvidia-driver | awk '{print $2}')
sudo apt autoremove

afterwards, use
dpkg -l |grep nvidia
to check if packages are left and uninstall them manually.

Hello,

I tried
sudo dpkg -P $(dpkg -l | grep nvidia-driver | awk ‘{print $2}’)
but it came up with

Also, when I try dpkg -l |grep nvidia, I get the same list as shown in my first post. (sorry, seems like I can only add one screenshot per post)

Is there a way to fix this? Also, how do I manually uninstall packages? Do I use sudo apt purge …?

Thank you!

generix · January 4, 2021, 2:32pm

Try
sudo apt remove cuda*
sudo apt remove nvidia*
sudo apt remove libnvidia*

Should I now run sudo apt autoremove as stated in the code above? Also, are the errors shown from sudo apt remove cuda* and suda apt remove nvidia* ok or do they also require fixing?

Thank you!

Please run the commands in an empty directory, otherwise it will run on the files in that directory.

Hello,

I tried running it in an empty directory and it seems to have worked.
Just one concern though: when I ran sudo apt remove nvidia* and selected Y to remove, it outputted the following:

Do I now just remove the remaining packages with sudo apt purge?
e.g. sudo apt purge libnvidia-compute-390:amd64

Thank you!

State ‘rc’ means that the packages are already removed but the config files are left over. You can either ignore them or use ‘purge’ to have a really clean slate.

Hello,

I tried following your instructions from earlier on but got some errors.

Adding the ubuntu graphics ppa resulted in the following error and warnings.

E: The repository 'file:/var/cuda-repo-10-0-local-10.0.130-410.48  Release' no longer has a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

A similar error also popped up when I tried sudo apt install nvidia-driver-455

After this operation, 1,021 MB of additional disk space will be used.

Is there a way to fix this?

The first error is normal, since it’s a local repo, no updates will occur.
The second one is because you added the cuda repo before installing the nvidia-driver from ubuntu repos, I guess.
Remove cuda again, reboot. Then install the driver from ubuntu repos using the “Software&Updates” application, reboot, check if the driver works.
Only then continue with cuda.

flyingalpaca · January 6, 2021, 9:00pm

Hello,

I used sudo apt remove cuda* and sudo apt autoremove to remove cuda and rebooted.

I then opened Software&Updates>>Additional Drivers>>Selected “Using NVIDIA driver metapackage from nvidia-driver-455 (proprietary, tested)”>>Selected “Apply Changes”
However, nothing happened and it states “No proprietary drivers are in use”.

Is there a way to fix this?

Thank you!

Is the nvidia driver still inactive after reboot? e.g. try running nvidia-smi

flyingalpaca · January 7, 2021, 7:39pm

Hello,

nvidia-smi outputs

Command 'nvidia-smi' not found, but can be installed with:
sudo apt install nvidia-340      
sudo apt install nvidia-utils-390

generix · January 7, 2021, 7:46pm

That’s a bit odd. Please run
sudo apt update
to renew the package lists. If that doesn’t help, add the graphics drivers ppa and install the driver from that.

flyingalpaca · January 7, 2021, 7:56pm

Hello,

sudo apt update also didn’t work and produces the following errors

Reading package lists... Done

Adding the graphics driver ppa with sudo add-apt-repository ppa:graphics-drivers.ppa and sudo apt-get update also gave the same error as above.

generix · January 10, 2021, 10:20pm

Please try removing it manually from /etc/apt/sources.list

flyingalpaca · January 12, 2021, 4:17am

Hello,

I’m not too sure what you mean.
What exactly am I supposed to remove and what do you mean by /etc/apt/sources.list

Thank you

generix · January 12, 2021, 8:32am

Please post the output of
cat /etc/apt/sources.list
