Solved: ./demo_security_barrier_camera.sh -d GPU Problem.

Kulecz__Walter · ‎06-11-2019

OpenVINO build l_openvino_toolkit_p_2019.1.144 in Intel Atom x5-Z8350 running Ubuntu-Mate 16.04 with all the latest updates. I'm happy to report that the issues I had with build 2019.1.133 now seem fixed.

Running ./demo_security_barrier_camera.sh -d CPU worked, got 7.65 fps, 8.67 fps inference.

But trying the GPU failed.

Ran to the very end, then failed with this error:

Run ./security_barrier_camera_demo -d GPU -d_va GPU -d_lpr GPU -i /home/ai/intel/openvino/deployment_tools/demo/car_1.bmp -m /home/ai/openvino_models/ir/FP32/Security/object_detection/barrier/0106/dldt/vehicle-license-plate-detection-barrier-0106.xml -m_va /home/ai/openvino_models/ir/FP32/Security/object_attributes/vehicle/resnet10_update_1/dldt/vehicle-attributes-recognition-barrier-0039.xml -m_lpr /home/ai/openvino_models/ir/FP32/Security/optical_character_recognition/license_plate/dldt/license-plate-recognition-barrier-0001.xml

Any ideas what has gone wrong? I've zero experience with openCL.

> I assume the GPU module won't work with an NVidia openCL, correct?

Correct GPU path only works on Intel GPU.

BTW

wget http://registrationcenter-download.intel.com/akdlm/irc_nas/11396/SRB5.0_linux64.zip

works for me here.

For the Intel GPU + discrete gfx system please connect monitor to system DVI / HDMI port (so that Intel GPU is active) and try clinfo again.

Cheers,

Dear Kulecz, Walter,

If you look at the Supported Devices document indeed FP32 should be supported on GPU, though FP16 is of course preferred. I was not able to reproduce your error. I just now tried on OpenVino 2019R1.1 for Windows. OS should not make a difference (I know you are using Ubuntu). But it looks like your OpenCL drivers may not be installed correctly, based on the error you are getting: failed to create engine: clGetPlatformIDs error -1001 or maybe your GPU device is not supported. The below command worked perfectly fine for me.

security_barrier_camera_demo.exe -d GPU -d_va GPU -d_lpr GPU -i "C:\Program Files (x86)\IntelSWTools\openvino_2019.1.148\deployment_tools\demo\car_1.bmp" -m "c:\users\sdramani\Documents\Intel\OpenVINO\openvino_models_R2\ir\FP32\Security\object_detection\barrier\0106\dldt\vehicle-license-plate-detection-barrier-0106.xml" -m_va "c:\users\sdramani\Documents\Intel\OpenVINO\openvino_models_R2\ir\FP32\Security\object_attributes\vehicle\resnet10_update_1\dldt\vehicle-attributes-recognition-barrier-0039.xml" -m_lpr "c:\users\sdramani\Documents\Intel\OpenVINO\openvino_models_R2\ir\FP32\Security\optical_character_recognition\license_plate\dldt\license-plate-recognition-barrier-0001.xml"

Thanks for your patience and thanks for using OpenVino !

Perhaps its a Windows vs. Linux issue? I note Windows is build 2019.1.148 while Linux is 2019.1.144

As I said, I have zero openCL experience, all I did was follow the "recipe" in the installation instructions at: https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux.html

It also possible the Atom x5-Z8350 is not the "correct" level of HD graphics. I am testing what systems I can get my hands on looking for the best bang/buck system for our needs, so I've been pretty good at finding errors in the instructions :)

As I said I've zero openCL experience. But MYRIAD and CPU options have worked fine. The demo give me:

CPU 7.65 fps, Inference 8.67 fps

NCS 11.35 fps Inference 11.65 fps

NCS2 17,68 fps Inference 18.87

Hello Kulecz, Waltern

The -1001 OpenCL error you have is CL_PLATFORM_NOT_FOUND_KHR that indicates "no valid ICDs found"

In other words OpenVino + clDNN cannot find a valid OpenCL GPU platform to execute inference when you use -d GPU.

First you need to install OpenCL so that when you ruin clinfo it will report valid OpenCL platforms and device and next try again OpenVino with -d GPU.

Another issue you may face is that the GPU must be HD 5** or higher. When we get the clinfo output from you we can see if this is the case or not. Please run

sudo apt-get install clinfo

and then 

clinfo

also from what I am reading the NEO OpenCL driver will not work in your system

https://software.intel.com/en-us/forums/opencl/topic/779709

Documentation so far indicates that your GPU is capable of running OpenVino.

However you need to find another way to install OpenCL. Probably something like this ( reference https://gist.github.com/cmey/a2b2223e7947b62bd94d405e290c9293 )

wget http://registrationcenter-download.intel.com/akdlm/irc_nas/11396/SRB5.0_linux64.zip
unzip SRB5.0_linux64.zip -d SRB5.0_linux64
cd SRB5.0_linux64
sudo apt-get install xz-utils
mkdir intel-opencl
tar -C intel-opencl -Jxf intel-opencl-r5.0-63503.x86_64.tar.xz
tar -C intel-opencl -Jxf intel-opencl-devel-r5.0-63503.x86_64.tar.xz
tar -C intel-opencl -Jxf intel-opencl-cpu-r5.0-63503.x86_64.tar.xz
sudo cp -R intel-opencl/* /
sudo ldconfig

keep trying until clinfo reports your OpenCL GPU device.

Good Luck!

Reading your other links, it sure looks not worth the effort. Its just I've yet to find a system with a" correct" integrated graphics chip.

The desktop I'm typing this one has integrated graphics, its enable in the BIOS but I use an Nvidia card for my two attached 4K displays.

Just for grins I installed clinfo and it reports one platform:

I haven't installed OpenVINO on this yet, as its the one system I can't risk breaking. Its a pretty low end graphics card, I used the integrated graphics initially but found it lacking when I went multi-monitor, so I got this card, ~3 years ago.

I assume the GPU module won't work with an NVidia openCL, correct?

Shubha_R_Intel · ‎06-12-2019

If the GPU is a supported Intel GPU security_barrier_camera_demo on GPU (using command-line specified above) should work fine, I tried it recently on OpenVino 2019R1.1.

Thanks,

Shubha

Correct GPU path only works on Intel GPU.

BTW

wget http://registrationcenter-download.intel.com/akdlm/irc_nas/11396/SRB5.0_linux64.zip

works for me here.

For the Intel GPU + discrete gfx system please connect monitor to system DVI / HDMI port (so that Intel GPU is active) and try clinfo again.

Cheers,

Thanks, I'll try again later with that zip file link.

I have a relatively new laptop with Nvidia graphics and Intel HD graphics. When I have a 4K monitor plugged into the external HDMI port it looks like the LCD panel can remain active as a "second" monitor and it appears to be then using the integrated graphics as the Nvidia "control panel" doesn't see it. I will try the openCL installation on this system when I upgrade it from 2019.1.133 to 2019.1.144 and see what clinfo says. Right now its running my NCS v1 SDK code to "stress test" an rstp to mqtt program as a way to add AI to existing stand-alone security DVR systems, I want the test to run at least through tomorrow if no problems are uncovered, its about at the 24 hour mark now.

Thanks so much for this. This download worked and using your earlier instructions I now have clinfo reporting 1 platform.

Running the demo with -d GPU I get 8.53 fps, 9.9 fps Inference.

CPU was 7.65 fps, 8.67 fps Inference

MYRIAD NCS was 11.35 fps, 11.65 fps Inference

MYRIAD NCS2 was 17.68 fps, 18.87 fps Inference

Thanks again, since you seem to have quite a lot of openCL knowledge, are there packages like this one available for other low-end integrated graphics systems?

I have:

i3-4025U

i5-4200U

i7-4500U

None of these worked with the NEO-OCL driver.

I think we can mark this thread as solved.

Hello Walter,

This is great news!

> for other low-end integrated graphics systems?

There are a few more packages from Intel we used earlier before NEO was born. I think the package above should cover most pre-NEO cases. There are older OpenCL installation documents from Intel that point to other packages too but the one mentioned here is the first I try on older GPUs. In some cases you need kernel patching but should be fine with new kernels now.

Unfortunately all Core i3-4025U, i5-4200U, and i7-4500U CPUs you have fall under the same category of 4th Generation Intel Core Processors that have Intel HD 4xx graphics that are not supported and they cannot run clDNN as we found after long investigation in this

therad https://software.intel.com/comment/1931157

Rule of thumb : your Intel GPU must be HD5xx or higher

More specifically it has to support

Queue properties:

Out-of-order execution - Yes (it can be found as one of the entries in clinfo)

Cheers,

Seems like solving this problem created another. After installing this openCL it seem my openVINO cv2 installation is now broken.

$ printenv PYTHONPATH

I'm stuck.

Thanks for confirming what I thought was the situation for those older GPUs.

Interesting issue!

Is this on the older atom x5-Z8350 system? Probably need to compile opencv from source.

nikos1 · ‎06-12-2019

btw this does not look like an opencl issue - could it be a tbb issue?

tbb = intel-threading-building-blocks

please make sure you source the setupvars script to set LDLIBRARY and other paths correctly

Yes its the old Atom x5-Z8350.

I'd used the Python cv2 just before I did the opencl installation. I cloned the system with dd before I did the opencl installation, so I can restore it pretty fast if poking around the librariy path doesn't give me any ideas.

I source setupvars in .bashrc. here is my library path:

Looks good. Sorry never had this issue but I am mainly using C++ not python.

Thanks for your help, I've learned a few things.

Restored the eEMC from my dd backup and Python OpenCV is working fine again.

Its somewhat distressing that installing openCL drivers/libraries can break something else, but the interlocking dependencies among all the pieces is getting close to being impossibly complex.

nikos1 · ‎06-13-2019

Glad to hear!

Yes it gets complex. I try to control all components manually and build most of them from source to avoid issues like that. It is fun :-)

If you don't mind, I've a new opencl issue on a different system.

I've installed 2019.1.144 on my i8750H Ubuntu-Mate 16.04 laptop. All the CPU and MYRIAD tests went fast and smooth.

This system has Nvidia graphics hooked to a 4K display on the external hdmi port and the laptop 1920x1080 LCD panel. I've the 4K as "primary" and the laptop display works or not depending on if its enabled or not in the Ubuntu-Mate "Display" tool. The NVidia control panel only "sees" one display -- the 4K monitor.

When I try the ./install_NEO_OCL_driver.sh script (after sudo -E su)

# ./install_NEO_OCL_driver.sh
Intel OpenCL graphics driver installer
Looking for previously installed user-mode driver...
dpkg-query: no packages found matching intel-opencl
dpkg-query: no packages found matching intel-ocloc
dpkg-query: no packages found matching intel-gmmlib

 dependency problems - not removing
Errors were encountered while processing:
 intel-igc-core
ERROR: unable to remove intel-igc-core
       please resolve it manually and try to launch the script again.

Results are the same with the laptop screen enabled or disabled. I've no idea how to "resolve it manually"

I had planned to wipe the NVMe drive and install Linux, but it came with an Western Digital NVMe that the installer and the installed system just can't "see" so it still has the Windows10 it came with. So I just got a 1TB SATA SSD and installed Linux to that and moved on. Someday I might try the OpenVINO install on Windows, but definitely not a priority as I got off the Windows bus at Windows 8.

nikos1 · ‎06-13-2019

Not sure how to solve this dependency without ssh in there :-)

Please take a lok at ./install_NEO_OCL_driver.sh

You could also try to install the latest runtime manually ( https://github.com/intel/compute-runtime/releases )

something like

mkdir neo
cd neo
wget https://github.com/intel/compute-runtime/releases/download/19.22.13062/intel-gmmlib_19.1.1_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.22.13062/intel-igc-core_1.0.6-2018_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.22.13062/intel-igc-opencl_1.0.6-2018_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.22.13062/intel-opencl_19.22.13062_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.22.13062/intel-ocloc_19.22.13062_amd64.deb
sudo dpkg -i *.deb
