Avoiding Discrete NVIDIA GPU

Jump to solution

Hi,

I installed OpenVino on Ubuntu 18.04 using the Apt method. My system has a discrete NVIDIA GPU and an Intel® Core™ i7-7700K CPU @ 4.20GHz × 8

I ran the CPU examples as suggested and they ran successfully:

> source /opt/intel/openvino/bin/setupvars.sh
> ./demo_squeezenet_download_convert_run.sh
> ./demo_security_barrier_camera.sh
> ./demo_benchmark_app.sh

 

When I run manually, it still works fine:

> ./classification_sample_async -i /opt/intel/openvino/deployment_tools/demo/car.png -m /home/michael/openvino_examples/models/FP16/squeezenet1.1.xml -d CPU
. . .

. . .

 

If I try to run on the GPU, it fails:

> ./classification_sample_async -i /opt/intel/openvino/deployment_tools/demo/car.png -m /home/michael/openvino_examples/models/FP16/squeezenet1.1.xml -d GPU

Please, check your environment
No OpenCL device found which would match provided configuration:
    GeForce GTX 1080 Ti: invalid vendor type

 

To verify there is an Intel GPU, I did this:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04)
01:00.0 VGA compatible controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)

 

I also verified the OpenCL DNN shared object is installed:

drwxr-xr-x 2 root root     4096 Dec  4 12:11 vpu_custom_kernels

 

If I ran the example with just the -h, it shows it can only see the CPU:

> ./classification_sample_async -h
[ INFO ] InferenceEngine: 
	API version ............ 2.1
	Build .................. custom_releases/2019/R3_ac8584cb714a697a12f1f30b7a3b78a5b9ac5e05
	Description ....... API
[ INFO ] Parsing input parameters
. . .
Available target devices:  CPU

 

How do I get the above example to run on the Intel GPU, and stop it from trying to run on the NVIDIA GPU?

Thanks for you help,

Michael

Hi Michael,

I was able to see the same issue, a couple of things I can suggest that worked for me:

  1. Make sure you have Internal/Integrated Graphics enabled in the BIOS. For my system once in BIOS menu, the setting was under Chipset > Internal Graphics > [Enabled].
  2. Follow required steps to enable the toolkit components to use the processor graphics (GPU ). Find the steps for Linux here.

I was able to see the same error you reported for Linux, after performing these steps I can run the OpenVINO* demo scripts just fine using the GPU plugin. I didn't have to remove the discrete graphics at all, both discrete and integrated are running. I hope this works for you and let us know if it does.

Note for users on Windows: for those running into the same issue on Windows* 10, for Step #2 above follow these steps instead. FYI I had to update my graphics driver using Device Manager > Display adapters > Intel(R) HD Graphics > Search automatically for updated driver software.

Best Regards,

Luis
