NVIDIA released a new version of the GPU driver in early January for the Tesla GPUs used in Azure. The Ubuntu DSVM is configured to automatically install updates, so these will be installed for you in the background.
You may need to reboot to complete the installation process and load the new driver. If you see the message Driver/library version mismatch
when running nvidia-smi or
nvidia-docker, a reboot will fix the issue.
We released a new Ubuntu DSVM image with these drivers already installed on January 15th. VMs provisioned after this date will already have the latest driver and will not require a reboot.
