Hi @sanath303

Thanks for your interest in Riva

Thanks for sharing the logs, cpu and gpu information

i guess the GPU present at your end is GeForce MX230
Apologies, I guess currently it is not supported
Please find the support matrix


Ohh yeah ,I want to practice ASR . Any solutions on what do to next ? I mean will you suggest any cloud servers which has Riva supported GPUs ?

@rvinobha any update regarding my query ?
I am very much enthuiastic to get hands on with riva so please spare few mintues

Hi @sanath303

We can use any cloud service (AWS, Azure, GCP etc.) which has the following configuration as per support matrix


Hey @rvinobha from your suggestion I started using azure nvidia-gpu-optimized-vmi-a10 vm

But there are no nvidia drivers in that VM and I am unable to install them also

Here are some commands and there outputs which can help in debugging the problem

Command : 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.

Command : sudo apt install nvidia-driver-495

Reading package lists... Done

Building dependency tree

Reading state information... Done

Package nvidia-driver-495 is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

**E:** Package 'nvidia-driver-495' has no installation candidate

Command : sudo apt install nvidia-495

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package nvidia-495

and for lspci command I am not getting any output

Some of the commands I tried
sudo add-apt-repository ppa:graphics-drivers/pp
sudo apt update

output for uname -a
Linux sanath 5.15.0-1020-azure #25~20.04.1-Ubuntu SMP Thu Sep 1 19:20:56 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

any updates @rvinobha ?
