Hi，I meet some problems installing NVIDIA driver.
My server is Azure with Standard_NC48ads_A100_v4, with no NVIDIA driver.
So I followed the steps in https://learn.microsoft.com/zh-cn/azure/virtual-machines/linux/n-series-driver-setup.
But after download and install,I entered "nvidia-smi" and received
"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.Make sure that the latest NVIDIA driver is installed and running"
Can you help us with the problem?Or can you help us with the NVIDIA driver install?
Some info of my server are as follows:
lspci | grep -i NVIDIA
0001:00:00.0 3D controller: NVIDIA Corporation Device 20b5 (rev al)
0002:00:00.0 3D controller: NVIDIA Corporation Device 20b5 (rev al)

You mentioned that you have a Standard_NC48ads_A100_v4 instance, which uses the NVIDIA A100 GPU. According to the NVIDIA website, the latest driver version for the A100 is 470.57.02. You can download this driver from the NVIDIA website (https://www.nvidia.com/Download/index.aspx).
Once you have downloaded the driver, you can install it by following these steps**1**:
- Open a terminal window on your server.
- Navigate to the directory where you downloaded the driver.
- Make the driver installer executable by running the following command:
chmod +x NVIDIA-Linux-x86_64-470.57.02.run - Stop the display manager by running the following command:
sudo systemctl stop display-manager - Run the driver installer by running the following command:
sudo ./NVIDIA-Linux-x86_64-470.57.02.run - Follow the prompts to install the driver.
- Once the installation is complete, start the display manager by running the following command:
sudo systemctl start display-manager
After the driver is installed, you should be able to run
nvidia-smiwithout any errors
