ModuleNotFoundError: No module named 'pytz'

[aksakalli]

For the version 0.311.0, pytz was removed from dependencies but included only for tests with the PR #160. I am getting ModuleNotFoundError: No module named 'pytz' although I did not set experimental_python_types=True or anything. I am just importing trino.dbapi.connect:

>>> from trino.dbapi import connect

Traceback (most recent call last):
