Cannot run Demo Scripts with GPU

[Yang__Edward]

OpenVINO version is 2018.2.300

OS Ubuntu 16.04.03

Platform Core i5-8400

====================================================

Just followed the Linux installation guide to setup my Openvino environment,

https://software.intel.com/en-us/arrticles/OpenVINO-Install-Linux

After performing the commands in the section of "Additional Installation Steps for Processor Graphics", I modified the demo script of "demo_security_barrier_camera.sh", replaced "CPU" with "GPU", then executed the script. The demo failed with the following messages:

I tried to run the demo of "" with GPU. Also failed with the same error

Please advise how to resolve this error. Thanks

This issue was resolved. Since the chipset is 8th generation Core i, we need to add:
   i915.alpha_support=1
to the 4.14 kernel command line. The GPU option worked well after I did that.

How did you add this "i915.alpha_support=1" command? I met the same problem, thanks!

Hi Edward,

To enable the i915 driver you need to append i915.alpha_support=1 to GRUB_CMDLINE_LINUX in /etc/default/grub and the run a sudo update-grub.

Hi

I encountered the same problem when I assigned the model to the "GPU".

We has found a solution to solve the problem:

[ ERROR ] failed to create engine: clGetPlatformIDs error -1001

Solution: Install OpenCl dependency

root@intel-desktop:/opt/intel/computer_vision_sdk/install_dependencies# ./install_NEO_OCL_driver.sh

Best Regards,

Rachel
