datasets question

[YuYuCodeNoob]

I am running my dataset conversion script on Ubuntu 20.04 LTS with ROS Noetic and encountered a rospy.exceptions.ROSInitException: time is not initialized. Have you called init_node()? error using python scripts/bag2data.py --path <rosbag dir path> --scene <scene name>. After initializing the node using rospy.init_node(), I faced error tf2.LookupException: "microstrain_link" passed to lookupTransform argument target_frame does not exist.. I would like to request a modification to the code. Thanks a lot.
