Dear @alksainath.medam,
It seems you have Ampere based GPU. Please check “Hardware prerequisites” at DriveWorks SDK Reference: Getting Started

This is the GPU I am using and it is of Turing architecture I think.
Can, you please check @SivaRamaKrishnaNV.

Dear @alksainath.medam,
Yes it is turing based GPU. Are you running sample on remote session?

5

I am not running sample on remote session; I am directly running on Ubuntu host.

7

It seems CUDA isn’t 10.2 which is compatible with DRIVE OS 5.2.6.
Please make sure running samples on a host set up by sdkmanager with DRIVE OS 5.2.6.
