Autoware: error in in running demo

edit

Hello When I am trying to run Demo using sample rosbag data from [link text] this link.(https://github.com/autowarefoun...

I am getting following errors

RLException: while processing ~/.autoware/data/tf/tf.launch:
Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'~/.autoware/data/tf/tf.launch'
The traceback for the exception was written to the log file

RLException: while processing /home/sai/Autoware/ros/install/runtime_manager/share/runtime_manager/scripts/calibration_publisher.launch:
Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/home/sai/Autoware/ros/install/runtime_manager/share/runtime_manager/scripts/calibration_publisher.launch'
The traceback for the exception was written to the log file

But The main problem is I have tf.launch in the same mentioned directory (/home/sai/.autoware/data/tf) and it is showing there is no such file or directory.

I am fine with second error since I am missing calibration_publisher.launch in that particular folder(i.e under install/runtime_manager/share/runtime_manager/scripts ) but I think it should come when i install autoware.

I also checked if i am some commits back from master and I am up to date with master.
