AttributeError: module 'asyncio' has no attribute 'async'

Hello. Cloned and built PyTango

Python version 3.7

ensure_future = getattr(asyncio, 'ensure_future', getattr(asyncio, 'async'))

I get this

giacomo@woody~ $ python Python 3.7.5 (default, Nov 15 2019, 13:43:34) [GCC 9.2.1 20191115 gcc-9-branch@278291] on linux Type "help", "copyright", "credits" or "license" for more information.
