提问参考模版：
- nebula 版本：2.0
- 部署方式 ：单机
- 问题的具体描述

def nebula_session(func):
@wraps(func)
def wrapped_function(*args,**kwargs):
# define a config
nebula_config = Config()
nebula_config.max_connection_pool_size = 10
# init connection pool
connection_pool = ConnectionPool()
# if the given servers are ok, return true, else return false
ok = connection_pool.init([(nebula_addr, nebula_port)], config)
with connection_pool.session_context(nebula_user, nebula_password) as session:
session.execute('USE tyc2021')
func(session,*args,**kwargs)
connection_pool.close()
return wrapped_function
之后，用这个装饰器
@nebula_session
def main(session,argv):
result = session.execute('SHOW TAGS')
print(result)
报错
