Install Intel GPU Drivers
- Check that you have permissions to access files/dev/dri/renderD\*and/dev/dri/card\*. This typically means that your user account is a member of the “video” (on Ubuntu* 18, Fedora* 30, and SLES* 15 SP1) or “render” (on Ubuntu* 19 and higher, CentOS* 8, and Fedora* 31) group. Alternatively, an administrator with sudo or root privilege can change the group owner of/dev/dri/renderD\*/dev/dri/card\*to a group ID used by your user base.
- For GPU compute workloads, non-root users do not have access to the GPU device. If you do not add a non-root user to the “video” group, all binaries compiled for a GPU will fail during execution. To fix this problem, add the non-root user to the “video” group:sudo usermod -a -G video <username>
