Buzzer could not function with HAT on Raspberrypi 3 B

Products & Technology Raspberry Pi
#1

I’m in ‘pi@raspberrypi:~/Grove_Base_Kit_Sketchbook/Tutorial_01-Buzzer $’ directory. When I type ‘sudo python Buzzer.py’, an error output:
Traceback (most recent call last):
File “Buzzer.py”, line 3, in
from mraa import getGpioLookup
ImportError: No module named mraa
Please advise. TQ

I’m really sorry, but there is something unreasonable in it.We’ll work on that as soon as possible, but you can use buzzer in the tutorial below.
