rpslam.py Error

[sonurdogan]

Hi! I am using raspberry pi 4 4gb and rplidar A1. I set up BreezySlam and run the rpslam.py example code but, I got a very different error. Code printed the map then I got the error. Error: python3 rpslam.py /usr/local/lib/python3.9/dist-packages/roboviz/init.py:65: MatplotlibDeprecationWarning: The set_window_title function was deprecated in Matplotlib 3.4 and will be removed two minor releases later.
