I got the following error when i tried to install Nuitrack on my newly installed linux system(16.04).
Does anyone know how I could fix this?

$sudo dpkg -i nuitrack-ubuntu-amd64.deb
(Reading database … 325479 files and directories currently installed.)

I tried to remove oppeni-ultis incase that might help but was not able to other packages were dependent on it.
$ sudo dpkg -P openni-utils
dpkg: dependency problems prevent removal of openni-utils:

Hi Pradeep,

Try to remove the openni-utils with the following command:

sudo apt-get remove openni-utils

hey Olga,
Just a follow up question, I activated my license with
sudo -E nuitrack_license_tool.

Then I built the nuitrack_ni_gl_sample as explained in the readme. but when i launch the created application nothing happens.
$ ./nuitrack_ni_gl_sample
Press Esc to close window.
Can’t create depth generator with error: Can’t create any node of the requested type!

Am I missing something?

What sensor do you use?

6

I have an Intel Realsense D435

7

nuitrack_ni_gl_sample doesn’t work with RealSense cameras as it works only with the sensors with OpenNI support.

8

Oh I didn’t know that. Thanks for the information. Does any of the other examples work with D435?

9

Yes, other samples should work fine, except for nuitrack_ni_sample (for the same reason).

I tried other examples and all of them gave similar results:

./nuitrack_console_sample

Do you connect your RealSense using USB 2.0 or 3.0? It’s important to connect it using USB 3.0.
Please provide us with 2 screenshots from realsense-viewer tool:

  2. Stereo Module > Resolution (list of modes)

@olga.kuzminykh hey,

I was able to make the examples and work. Will post here with the results of my project once I am done. Thanks for your help.
