Couldn't create user tracker

[lenovir]

when I roslaunch kinect2_tracker tracker.launch,there's an error:

Could not find data file ./NiTE2/s.dat
current working directory = /home/huangdan/.ros
[FATAL] [1555235316.166777268]: Couldn't create user tracker
[kinect2_tracker_node2-2] process has finished cleanly
log file: /home/huangdan/.ros/log/77e934e0-5e9a-11e9-951d-acd1b884bee7/kinect2_tracker_node2-2*.log

but NiTE-x64-2.2 ./UserViewer is OK
how can I solve the problem

Same here, did you manage to figure it out?

I just copied the libfreenect2 package to your_ws/src and rebuilt the libfreenect2 package. The error just disappeared.
