Ubuntu advanced installation - prerequisites#

To use GPU and/or NPU as an inference devices or to use graphics hardware encoding/decoding capabilities, it is required to install appropriate drivers. The easiest way to install these drivers is to use automated script described in: Install Guide Ubuntu. This documentation describes how to do these steps manually.

Prerequisite 1 - Intel® GPU drivers for computing and media runtimes#

To use GPU as an inference device or to use graphics hardware encoding/decoding capabilities, it is required to install GPU computing and media runtime drivers. Please follow the up-to-date instruction according to your hardware:

Prerequisite 2 - Install Intel® NPU drivers#

Note

Optional step for Intel® Core™ Ultra processors

If you want to use NPU AI accelerator, you need to have Intel® NPU drivers installed.

  1. Before installation, please make sure that intel_vpu.ko module is enabled on your host:

user@your-host:~$ lsmod | grep intel_vpu
intel_vpu             245760  0

  1. Installing the driver requires the device to be recognized by your system - Kernel Mode driver should be available. It means you can see a accel device in /dev/dri directory. If you don’t see it, please reboot the host.

    user@my-host:~$ ll /dev/accel/ | grep accel
crw-rw----  1 root render 261, 0   Aug  6 22:41 accel0

  2. Install the newest Intel® NPU driver. Please follow ‘Installation procedure’ for the newest available driver version described in: intel/linux-npu-driver

Note

If you are experiencing issues with installation process, check all notes and tips in the release note for the newest Intel® NPU driver version: intel/linux-npu-driver. Please pay attention to access to the device as a non-root user.

Note

The following error can be reported when running Intel® DL Streamer on NPU device:

Setting pipeline to PLAYING ...
New clock: GstSystemClock
Caught SIGSEGV
Spinning.

In such case, please use the following setting as a temporary workaround:

export ZE_ENABLE_ALT_DRIVERS=libze_intel_vpu.so

The issue should be fixed with newer versions of Intel® NPU drivers and Intel® OpenVINO™ NPU plugins.
