"Python error: <stdin> is a directory, cannot continue" error when starting example

[deer-in-the-woods]

Hello, I am trying to get this tool running. When I ran the code as stated in the readme file:
roslaunch kitti_ros kitti_player.launch kitti_data_path:=</home/****/Downloads/2011_09_26_drive_0001_extract/2011_09_26/2011_09_26_drive_0001_extract> fps:=1

I get this error:
Python error: <stdin> is a directory, cannot continue
and the code exits.

It would be nice if someone would help me.
Thanks in advance.
