Cuda 9.0 doesn't work with nvidia drivers 390?

For a specific github repo, I need to have Cuda 9.0 installed, but after installing cuda 9.0, I have the following error :

WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu is not available  (error: Unable to get the number of gpus available: CUDA driver version is insufficient for CUDA runtime vers



dkms status

gives me

nvidia, 390.116, 4.15.0-20-generic, x86_64: installed

while on this page it’s written that cuda 9.0 should work with any driver higher than 384.81. How to resolve this problem ?

Also, nvidia-smi gives me this :
| NVIDIA-SMI 390.116 Driver Version: 390.116 |

and I downloaded “”

Thank you for your replies

Snooping around, my problem seems to be similar to this even though I’m not using tensorflow :

They mentioning updating my drivers to 396, or downgradind the drivers to 384 but here’s the issue :


ubuntu-drivers list

returns only :


and in driver manager, the only avaiable driver is also nvidia-driver-390. Obviously, running

sudo apt install nvidia-driver-396 l


Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package nvidia-driver-396

and running this, which I don’t understand but was talked about :

sudo add-apt-repository ppa:graphics-drivers/ppa

returns this :

which again I don’t understand. Please help me ! I desperately need to be able to do this for my master thesis.

So I have finally figured out how to install drivers 396 (actually I haven’t figured it out, it magically worked at some point), but it’s still the same error… Gonna keep trying but it’s hard not to give up

I never recommend installing NVIDIA drivers from ppa or other sources that are not managed by NVIDIA. It is possible for a NVIDIA driver to be modified by a 3rd party (removing components) with the result that certain kinds of functionality won’t work.

In addition, it seems you are installing on a laptop. Most NVIDIA GPU laptops nowadays are Optimus laptops, which means that they have both an intel “iGPU” and nvidia “dGPU” that together are controlling the display. This makes driver install more complicated. It also makes runtime usage of the dGPU more complicated.

You’re welcome to do what you wish of course. But there are plenty of instructions on how to install a NVIDIA GPU driver available on the web, so I’m not going to repeat that here.

If you think you have everything installed correctly, but its not working on a Optimus laptop, it may be because the dGPU is shut off. You can investigate methods to turn it on, either using your laptop system BIOS, or by investigating methods such as nvidia-prime for linux.
