Hi, i am new to ROS2 and pointcloud. I have Lidar data in rosbag. i want to convert it into kitti dataset format .bin files i wanted to use pypcd to read the data but its giving following issue

pc = pypcd.PointCloud.from_msg(loc[indx])

File "/home/robot/.local/lib/python3.8/site-packages/pypcd/pypcd.py", line 779, in from_msg raise NotImplementedError('ROS sensor_msgs not found') NotImplementedError: ROS sensor_msgs not found
