You need to add from __future__ import annotations to support new type hint in python3.8/3.9

from future import annotations was previously scheduled to become mandatory in Python 3.10, but the Python Steering Council twice decided to delay the change (announcement for Python 3.10; announcement for Python 3.11). No final decision has been made yet. See also PEP 563 and PEP 649.
