issue when running the create_database.py

[ZhihongMiao]

I am really new in this area. I just download your code and try to run it in the anaconda environment using PyCharm. But I met below error. I have installed all the packages mentioned in the requirements.txt. Could you please comment what happened here? Thanks.

Traceback (most recent call last):

This seems to be a Python version error, if you are using lower than 3.7, update the environment to 3.8
__future__ was included in 3.7
