Hi,

I'm new to ROS and just managed to install Groovy on Ubuntu 12.04. After installing the openni packages I'm able to receive the disparity and RGB image from my Kinect, but if I want to start the skeleton tracker by calling rosrun openni_tracker openni_tracker, I just get the error

[ERROR] [1360932563.459904042]: Find user generator failed: This operation is invalid!

Has anybody ever experienced the same error and knows how to fix it?

Thanks for your help!

Ubuntu 12.10, ROS Groovy.

I had a bit of trouble downloading the correct version of NITE.

The first couple of time I tried:
1. OpenNI-Bin-Dev-Linux-x64-v1.5.4.0.tar.zip
2. NiTE-Linux-x64-2.0.0.tar1.zip

Both of which had no uninstall.sh files. Only the install.sh file.

Finally, I found [NITE-Bin-Linux-x64-v1.5.2.21.tar.zip] (http://www.openni.org/wp-content/uploads/2012/12/NITE-Bin-Linux-x64-v1.5.2.21.tar.zip)

This last version had the uninstall file. After running it as sudo and then running the install.sh file, everything worked.

Hi! I had the same issue but on ROS Fuerte with Ubuntu 12.04 x86. I followed steps from this that Stephanie.M suggested in some other post (my karma is to small to publish links), namely:

"In order to solve it : 1) go to openni page 2) download old nite from openni-sdk-history ( NITE 1.5.2.21 ) 3) "Unzip" 4) "Ungz" 5) Launch the uninstall script first ! 6) Launch the install script"

It worked for me :)

Cheers, da-na

Thanks for the suggestion. I've already tried this, but afterwards I was not even able to connect to my Kinect any more (I always received the message "No devices connected..."). Had to completely delete all openni components and reinstall ROS in order to be able to connect again.
