Does the openVX can run on the Neural Compute Stick 2?

[jsmit119]

The cnn can run on the Neural Compute Stick 2, but I can't find a way to run openvx on Neural Compute Stick 2.Does the openVX can run on the Neural Compute Stick 2?

Dear Joe, 

OpenVX does not run on NCS2.

Best, 

Severine

hi,

I bought ncs2 2 weeks ago and install openvino according to this guide

https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick

d:\Program Files (x86) 2\IntelSWTools\openvino\openvx\samples\samples\

If Intel stops to use

From openvx README, i build the samples like this: (see BOLD below)

I like the example "lane_detection" and "motion_detection", a shame if Intel stop to use openvx. I saw the version of openvx Intel attached inside the installation is 1.1.0.cb9b578d_Atom.1. Openvx  has released version 1.3 . I hope Intel development team will do something (continue to support) and not already drop NCS2.  https://github.com/KhronosGroup/OpenVX-sample-impl

i run ncs2 on Lenovo w540 with an old webcam, i tried this python script using ncs2. It works, but the fps is too small. http://www.chezmoi.dk/upload/ncs2-usb-racing-realtime.mp4

ops!! i found out, inside the d:\Program Files (x86) 2\IntelSWTools\openvino\openvx\samples\README  file it says:
 
Open generated solution file in Visual Studio and build it. Make sure that INSTALL project is built,
in this case <SAMPLES_BIN_INSTALL> will be populated. The content of this directory is described
in the next section of this document.

Ok, you can build them directly from command line with this one:

d:\Program Files (x86) 2\IntelSWTools\openvino\openvx\samples\samples\build>cmake --build . --config Release

It will build all the exe of the samples at the folder "Release"

Work wonderful!!!

VERY VERY STRANGE Intel
Even i unplug the ncs2 USB stick from my laptop, everything still run fine??? i expect it will failed when I dont had that coprocessor device (ncs2) attached at the usb port. What happened here?

ncs2 plug in:

:-( why dont you post my post, there are 2 of them

[TNguy219]

If you want to review every post, sorry it is my last Intel AI device i will buy, and I will tell other "you dont get support anyway from Intel", better with Nvidia. If you dare sent it to your boss

Hello, Van N.

We apologize for the inconvenience. Usually such old threads (this one is almost a year) are not being monitored.

Lane Detection sample utilizes OpenVX that might be run only on CPU and GPU. It does not support VPU devices like NCS2.
In your case I believe it runs exactly on CPU, so that's the reason why nothing happened when you unplugged your NCS2.

Best regards, Max.
