@ADLATUS that solution is for kinetic and not melodic

The person, who answers mentioned that it's for Melodic. But it doesn't matter you can change commands with your <ros-distribution>

@Petros ADLATUS I followed the instructions and got a folder in my workspace with tf2 files I think worl in python3, but I have no idea how to link code to use those folders instead of the default python 2.7 tf library. Would you know how to do that?

maybe this can help you https://github.com/ros/geometry2/pull.... Did you set the Python Path in the bashrc file?
