Hello, I got a problem when I tried to

roslaunch openni_launch openni.launch

with kinect v1 on my ubuntu16.04

#----------------------------------------------------------------------

1. My computer environment:

ubuntu 16.04 + kinetic

OpenNI-Bin-Dev-Linux-x64-v1.5.7.10

Sensor-Bin-Linux-x64-v5.1.2.1

NITE-Bin-Dev-Linux-x64-v1.5.2.23

#----------------------------------------------------------------------

2. When I tried to roslaunch openni, I got the message as following:

... logging to /home/neo/.ros/log/75389ba0-8c86-11e8-b414-00215ce868e5/roslaunch-nuc-16200.log
