import tta_wrapper throwing 'Syntax error'

[Sriharsha-hatwar]

Below is the traceback and the libraries installed in my conda env.
My suspect is Python 3.5 let me know how to resolve this.
I Believe I need to update the Python 3.5 to 3.7 without disturbing the environment( idk how to do it ) suggestions are welcome
