 Since Autoware is based on ROS 2, it could be problematic if you want to install ROS 1-based SLAM implementations on the same machine. To avoid this problem, you can use [Docker](https://www.docker.com/) or simply install them on a different machine. Another problem is the ROSBAG version; these SLAM implementations require ROSBAG 1 instead of ROSBAG 2 used by Autoware. For the ROSBAG version problem, you may use this [stand-alone converter](https://gitlab.com/MapIV/rosbags) to convert a ROSBAG 2 file to a ROSBAG 1 file and vice versa.
