rosbag(http://wiki.ros.org/rosbag) is a data type that must be used in pilotless car, We hope ray can support rosbag in the scene for simulation training of pilotless car
If I understand correctly rosbag is a file format, is that right?
Just from a preliminary search, looks like you can use the bagpy library (GitHub - jmscslgroup/bagpy: Python package for reading, and extracting data from rosbag files and performing any analysis on it.) to read rosbag files into Pandas dataframes, which allows you to use it with Ray Datasets.
@Runlin_zhang Does the alternative work for you? As @amogkam pointed out, Pandas DF an be easily converted into Ray Data.
If this suggestion works for, can be consider this resolved. Thanks!
