我执行了下面的代码，它显示了这个错误。
下面是代码片段。

import pymysql
mydb = pymysql.connect(
    database = "q11",
    user = "111",
    password = "11111",
    host = "localhost"
)

我得到的错误是：

pymysql.err.OperationalError: (2006, "MySQL server has gone away (ConnectionAbortedError(10053, 'An established connection was aborted by the software in your host machine', None, 10053, None))")```
