GrovePi on PI3 grove_button.py not work

Hi
I try to run grove_button.py on RPI 3.
but digitalRead(button) not return 1 after press button.

but, grove_button.py runs perfect on RPI 2.
digitalRead(button) will return 1 after press button.

Any suggestion ?

Hi @kenghao_chen,

Can you tell us what image you are using on Pi2 and Pi3. If you are using Raspbian for Robots image, can you follow this guide, generate a log and post along with your reply.
