Hi @塚田 真輝,
Welcome to the Microsoft Q&A Platform! Thank you for your question and for providing the information.
We understand from your query that you are experiencing an issue while trying to access with nvidia-smi. $ 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.
At this time, you need to check whether the nvidia driver is correctly installed, or update to the latest version of nvidia-drivers.
The Azure NVads A10 v5 VMs only support GRID 14.1(510.73) or higher driver versions. The vGPU driver for the A10 SKU is a unified driver that supports both graphics and compute workloads. Please refer to this: https://learn.microsoft.com/en-us/azure/virtual-machines/linux/n-series-driver-setup#supported-distributions-and-drivers
Uninstall the vGPU driver to start from a clean slate. Reinstall the vGPU driver using the correct installation method for your system. Make sure to follow the official NVIDIA documentation for installing the vGPU driver on Ubuntu Server 22.04 LTS. https://docs.nvidia.com/datacenter/tesla/driver-installation-guide/index.html
