Object Detection for Faster R-CNN Demo Using the NCS2

[wang__xiujie]

I run the Object Detection for Faster R-CNN Demo in https://software.intel.com/en-us/articles/OpenVINO-IE-Samples. Ubuntu16.04.

And I met a problem as follows. I am new to NCS2 and thank you a lot if you can help me!

Hi Xiujie,

It seems that your build wasn't able to find the dependencies, have you tried running the "setupvars.sh", I only have Windows right now but looking at the forum the shell script that initializes the environment  should be located in this path:

/opt/intel/computer_vision_sdk_2018.X.XXX/bin

If that doesn't work try to look for the missing dependencies and include it in your path environment.

You can look at this: Edit LD_LIBRARY_PATH

Needles to say, you should also try to edit the version "computer_vision_sdk_2018.X.XXX" relevant to your OpenVino.

Hope this helps!

Regards,
Joel

Dear wang, xiujie,

This should work right out of the box for you.  Please carefully revisit the Linux OpenVino Installation Steps . And pay close attention to The VPU Part . The error you're experiencing usually happens if you skip one of the steps, as someone suggested - maybe you didn't do this :

sudo -E ./install_openvino_dependencies.sh

Also you need to make sure you run setupvars.sh from the shell that you execute any samples and demos.

Thanks,

Shubha
