Error "no devices found" with ASUS Xtion2

[shsh946]

As title
Environment: Win10/Python3.7
openni.Device.open_any() can not found the Xtion2
But ASUS_NiViewer2.2 can work correctly

Hei, my ASUS Xtion Pro Live maybe have the same problem.
I run ./SimpleViewer on ubuntu18, got "Open device failed: DeviceOpen using default: no devices found "

Hi ccl-private, is NiViewer working for you ? Sorry for the stupid question but.. have you run the install script that is under Packaging/Linux in OpenNI folder ?
Just to be sure you can follow this guide: https://github.com/occipital/OpenNI2 at the end just run the script, it will basically copy udev rules for the camera..

@roccopietrini, thanks. Both NiViewer and SimpleViewer worked.
But I still have a problem with NiTE2 Examples in README.md.

My NiTE2 downloaded from http://cvrlcode.ics.forth.gr/web_share/OpenNI/NITE_SDK.

I'm not an expert but I suspect that Nite don't find OpenNI.. Try this

@roccopietrini, Recently I reinstalled my os to debian10, something was wrong with NiTE again.OPENNI works fine. I Don't know whether it is because I forget something to set or not. And here are my 3 steps:

The code in test.py is the first example of NiTE2 usage with my paths of OpenNI and NiTE added.
here is the error message:

It's been long time since I last used this things, but if I remember well when you call some NiTE2 functions it looks for the model files in the same level, under a NiTE2 directory, for example.. ./NiTE2/s.dat
From the error message you get I guess it doesn't find this directory.. what I was doing is symlink the directory NiTE2 in the path where your program is..
Hope it helps.

Thank you～
I put NiTE2 and OpenNI2 into my project, and it worked.
