当我尝试用SQLAlchemy连接oracle服务器时，我得到这个错误。
无此类模块错误：无法加载插件：SQL炼金术。方言：oracle。oracledb

from sqlalchemy.engine import create_engine

DIALECT = 'oracle'
SQL_DRIVER = 'oracledb'
USERNAME = 'username' #enter your username
PASSWORD = 'password' #enter your password
HOST = 'host url' #enter the oracle db host url
PORT = 1533 # enter the oracle port number
SERVICE = 'service name' # enter the oracle db service name
ENGINE_PATH_WIN_AUTH = DIALECT + '+' + SQL_DRIVER + '://' + USERNAME + ':' + PASSWORD +'@' + HOST + ':' + str(PORT) + '/?service_name=' + SERVICE

engine = create_engine(ENGINE_PATH_WIN_AUTH)

# test query

import pandas as pd
test_df = pd.read_sql_query('SELECT * FROM global_name', engine)

有什么不同连接方法吗？
