Disable output of VisionFive.i2c.open

I am doing some stuff with newest debian image (August) and downloaded VisionFive.gpio package for Python environment.
Then I found that every time when I called I2C.open this method, such as

import VisionFive.i2c as I2C
I2C_DEVICE = "/dev/i2c-0"

The terminal will always output " i2c_dev: /dev/i2c-0 "
it is not stderr nor stdout, I can not get rid of it at all
I use curses as GUI so the output makes the whole app not workable
Any one knows how to get rid of it, or what package can I choose as a GUI
