按照nebula-python的官方说明，进行连接池的初始化，执行到验证用户名和密码那一步时报错：

报错代码和官网提供的例子基本一致
# define a config
config = Config()
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([('192.168.xxx.xxx', 7001)], config)
# get session from the pool
session = connection_pool.get_session('root', 'password')
# show hosts
result = session.execute('SHOW HOSTS')
print(result)
# release session
session.release()
# close the pool
connection_pool.close()
报错语句：session = connection_pool.get_session('root', 'password')
