Maybe you can try following to install python-evdev, which allows you to read and write input events on Linux, keyboard in this tool

$ sudo apt-get install python-evdev

@Durant35 Thanks!

1. I find I don't have the timestamps.txt that kitti_player.py needs, where can I get it;
2. And when I run demo.launch, it can't find the detection_node, I find it , but don't know how to deal with it.

@Durant35 sorry I didn't see the kitti_ros for detail, I am succeed with the kitti_player.launch.

But I still cannot launch the demo.launch in segementers_lib.

Maybe you can see this repo for detail. open a new issue about that if need, for better communication.
