tf2 for ROS melodic

I would like to install tf2 for python3 environment in ROS-melodic but the github seems to only have it for neotic. Is there a tf2 out there for ROS-melodic?

@abhishek47 from my pe=reviouso comment I looked deeper into my files because the error says there's a problem with python2.7 in my ros, apprenetly I dont have python3 for ros, which I thought I did. WOuld you happen to know how to switch from python 2.7 to 3?
