2017-03-27 00:56:51 -0500 asked a question How to visualize PointCloud2 in rviz

I have a BAG file, XXX.bag

I started roscore and rosbag play XXX.bag. Then I opened rviz.

I added a PointCloud2

But I got an error Transform[sender=unknow] For frame [velodyne] fixed frame [map] doesn't exist

My global options has fixed frame map

I am new to ROS. I don't understand any of these error messages.
