Run OpenVINO demo with GPU failed (ubuntu 16.04 with NVIDIA display card)

Hello,

I try the demo in ubuntu 16.04, when I run it with CPU, it is OK, with GPU, it failed. 

run : /opt/intel/computer_vision_sdk/deployment_tools/demo$ ./demo_security_barrier_camera.sh -d GPU

OpenCL is installed, when OpenCL is not installed, the log do not show " Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz: invalid device type"

Hello,

I am afraid that the Intel HD graph is not work, for I use a Nvidia display card as primary device.  

When I use "lspci |grep VGA" to show, but not found any word about "Intel HD" at all.

You should be able to see the Intel HD Graphics 630 GPU too. Sometimes it can be tricky with dual GPU systems like yours. You may have to enable Intel GPU from BIOS and you may also have to connect a monitor to the system DVI/HDMI port (not on the discrete graphics ports).

FWIW I had a similar system and GPU configuration and my Intel HD worked fine when using the same sample with -d GPU.

BTW there was a similar issue on Windows https://software.intel.com/en-us/forums/computer-vision/topic/785425

Hi Nikos,

  Thanks you very much!

  For current development env is co-used with workmates, he is trying a CUDA program, so I will not do more trying to config this env.

Best Regards,

Ke

Hi Ka,

You are welcome.

BTW I am also doing a lot of CUDA work and OpenCL development and AI work and I have both GPUs happily co-existing in my system. It is possible. You may have to connect one monitor to the discrete GPU and a second monitor to your motherboard. Your HD Graphics 630 GPU is a nice AI accelerator and will run at high framerates with very low CPU load.

Cheers,

Nikos
