Hi, i am running impyla python client as follow, however no attribute error raises, Could anyone advice on this?

conn = connect(host='localhost',
               user='xxx',
               password='xxx',
               database='test',
               port=10000,
               auth_mechanism='PLAIN')
cur = conn.cursor()
cur.execute('select * from employee')
rows = cur.fetchall()
for row in rows:
    print(row)
