Troubleshooting NVIDIA GPU

Visual Inspection AI requires a supported NVIDIA GPU model to run. Check the status of the NVIDIA card and drivers.

Run on Edge Server

Run the following command to check the Ubuntu drivers’ status for NVIDIA:

 ubuntu-drivers devices

The command should output similar to:

 == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
 modalias : pci:v000010DEd00001E82sv00001043sd00008674bc03sc00i00
 vendor   : NVIDIA Corporation
 model    : TU104 [GeForce RTX 2080]
 manual_install: True
 driver   : nvidia-driver-460-server - distro non-free
 driver   : nvidia-driver-418-server - distro non-free
 driver   : nvidia-driver-450-server - distro non-free
 driver   : nvidia-driver-460 - distro non-free
 driver   : nvidia-driver-470 - distro non-free recommended
 driver   : nvidia-driver-470-server - distro non-free
 driver   : xserver-xorg-video-nouveau - distro free builtin

Run the following command to check the loaded NVIDIA driver version:
```
 nvidia-detector
```
The output is similar to:
```
 nvidia-driver-495
```
Run the following command to check that the NVIDIA GPU is visible to the system:
```
 prime-select query
```
The command should output:
```
 nvidia
```
If the command outputs something different, for example ‘intel’, execute the following command to try to switch the system to use NVIDIA:
```
 prime-select nvidia
```

Run the following command to query the NVIDIA card and its driver status:

 nvidia-smi

If successful, the output should be similar to this:
