Can't run object detection sample with GPU

[CLu1]

OpenVINO version is 2018.1.265

OS Ubuntu 16.04

Platform N4200 UP2 board

Then I run  "sudo -E ./object_detection_sample_ssd -d GPU -i ./car_300x300.bmp -m ./ssd300.xml"

It show below information.

Hi Collins L.,

for the platform N4200 UP2 board, OpenVINO™ toolkit only supports CPU as target hardware as you can find at this link: https://software.intel.com/en-us/openvino-toolkit (section Target System Platforms).

Best regards, 

Severine

Hi Severine,

Thanks!

But N4200 it has Intel HD Graphic.

CPU:

• 6th to 8th Generation Intel Core and Intel Xeon processors
• Intel® Pentium® processor N4200/5, N3350/5, N3450/5 with Intel® HD Graphics

Graphics:

• 6th to 8th generation Intel Core processor with Iris® Pro graphics and Intel HD Graphics
• 6th to 8th generation Intel Xeon processor with Iris Pro graphics and Intel HD Graphics (excluding the e5 product family, which does not have graphics)

Hi Colins L.,

I know it is a bit confusing but as you can see Intel® Pentium® processor N4200/5, N3350/5, N3450/5 with Intel® HD Graphics is only listed under CPU and not Graphics (GPU). So even though it has Intel® HD Graphics, it won't be able to run with -d GPU option. Your CPU would need to be Core or Xeon for being able to run with -d GPU option. 

Best regards, 

Severne

Hi Severne,

Thanks.

By the way, May I ask the other question?

The compatible OS for N4200 is Yocto project.

Does it mean there is no support for N4200 with ubuntu OS ?

CPU

Processors	Compatible Operating Systems
6th to 8th generation Intel Core and Intel Xeon processors	Ubuntu 16.04.3 LTS (64 bit) Windows 10 (64 bit) CentOS 7.4 (64 bit)
Intel® Pentium® processor N4200/5, N3350/5, N3450/5 with Intel® HD Graphics	Yocto Project* Poky Jethro v2.0.3 (64 bit)

Hi Collins, 

the requirements page shows where the hardware has been tested and is supported. It might happen that, out of the list, it works. We can not assure it and support it, however. 

Update 09/05/2018:  our dev team has tested Platform N4200 UP2 board with OpenVINO and it is working.

Best, 

Severine

Hi,

just to place a confirmation here.

Pentium N4200 is working in GPU mode (tested on current R4 OpenVino) on Up Squared board.

Our setup uses Debian 9 with regular kernel 4.9.135 and intel-opencl_18.42.11702_amd64.deb driver.

Hi Collins L.,

I also agree with om77 that you should be able to get the https://ark.intel.com/products/95592/Intel-Pentium-Processor-N4200-2M-Cache-up-to-2-5-GHz-  to run -d GPU. I had it working before too.

First step would be to install OpenCL environment and get clinfo to enumerate and report the Intel GPU device. There are threads that have some tips on how to achieve this. Can be tricky and you may have to get a more recent kernel.

Cheers,

Nikos
