how to solve this syntax error in jupyter notebook

Question

I am trying to connect jupyter to mysql database using this syntax:

%sql mysql+pymysql://root:mother@123@localhost:3306/united_nations 

but i am getting the below syntax error:

MetaData.__init__() got an unexpected keyword argument 'bind'
Connection info needed in SQLAlchemy format, example:
               postgresql://username:password@hostname/dbname
               or an existing connection: dict_keys([])

I was expecting to connect jupyter notebook to mysql database
