2-02 모델로 데이터베이스 관리하기 하고있는중인데여

import models 를 추가하면 되는것일까요?

저의 경우 env.py부분에

from logging.config import fileConfig

from sqlalchemy import engine_from_config
from sqlalchemy import pool

import models

# this is the Alembic Config object, which provides
# access to the values within the .ini file in use.
config = context.config

# Interpret the config file for Python logging.
# This line sets up loggers basically.
if config.config_file_name is not None:
    fileConfig(config.config_file_name)

# add your model's MetaData object here
# for 'autogenerate' support
# from myapp import mymodel
# target_metadata = mymodel.Base.metadata
target_metadata = models.Base.metadata

로 작성해서 프로그래밍을 돌렸을떄
sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:driver
에러가 발생합니다 무엇이 문제일까요
