Custom engine creation SQLAlchemy in module

I have a project where i want to isolate DB initialization (SQLAlchemy) from the other module so i've create a module

db_initializer.py

engine = create_engine('sqlite:///db')  # TODO from config file
Session = sessionmaker(bind=engine)
Base = declarative_base(bind=engine)


def create_tables():
    Base.metadata.create_all(engine)

First of all i need to put create_all in function because my model is in an other package

model/foo.py

from core.db_initializer import Base

class User(Base):
    __tablename__ = 'user'

    id = Column(Integer, primary_key=True)
    name = Column(String)

    def __init__(self, name: str = None):
        self.name = name

    def __repr__(self):
        return "<User(id=%d, name=%s)>" % (int(self.id), str(self.name))

And my main call create_tables.

Is there any other to do that ? And now i need to create the engine with custom config (IP,User, ...) and only the main script know the config it's possible ?

Something like

main.py

import db_initializer as db
import model.foo
db.init(config) # which create the engine and create table 

When i do something like that i got problem with the Base object which have not bind to the engine which is not created yet... Any solution ?
