Warning "No map received" occurs.
Hello.I'm trying to use slam_karto.
But when I try to see the visual map in the Rviz ,the map model warns 'no map recevied'.
I can see the LaserScan.And the dataset can run correctly on 'gmapping slam_gmapping.
I'm sure the topic name is used rightly.
My step:
rosrun slam_karto slam_karto
rosbag play catkin_ws/data/inter.bag
When I play the inter.bag,slam_karto prints these:
...
LaserRangeScan contains 180 range readings, expected 181
LaserRangeScan contains 180 range readings, expected 181
LaserRangeScan contains 180 range readings, expected 181
...
Up to now , I still confuse how to use slam_karto to run dataset.
Can you help me?
It seems you dont have karto configured correctly.
Do you means I dont install karto correctly?I just clone karto_slam from github not open_karto,is it wrong?
Karto is fine but look at the error you're seeing. What does it mean?
Hint: some of the meta data in your laser scan message is probably incorrect. Here's where your error lies

Thank you a lot!I think that's the key! I dont find corresponding dataset,so I download from there and transform '.clf' to '.bag'. Could you tell me where I can download the right dataset?Thanks!
