I installed NVidia drivers for GeForce GT 635M. Last version 390.

if I understand correctly, I need to install CUDA 9.0 (9.0.76). But I can see only Installer for Linux Ubuntu 17.04 x86_64.

I tried to get Installer for Linux Ubuntu 17.04 x86_64

$ sudo dpkg -i cuda-repo-ubuntu1704_9.0.176-1_amd64.deb
$ sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1704/x86_64/7fa2af80.pub
$ sudo apt-get update
$ sudo apt-get install cuda

and recieved results

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created
or been moved out of Incoming. 
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 cuda: Depends: cuda-9-1 (>= 9.1.85) but is not to be installed
E: Unable to correct problems, you have held broken packages.

I tried install CUDA 9.0 (9.0.76) and CUDA 9.0 (9.1.85), but in all cases have trouble.

Can you help me compile compatible versions?

GT 635M is a Fermi device. It is obsolete and no longer supported by current CUDA versions or drivers.

390.xx was the last driver supporting that device.

CUDA 8.0 was the last CUDA version supporting that device.

Thank a lot, I will try soon and post results.

But, can you talk me, how I can understand it from official site?

Thank, I can install cuda 7.5 on Linux 16.04 and GeForce GT 635M.
