This is caused by the same thing as #464, and we'll fix it in the next version of Chaquopy. Meanwhile, you can work around the problem like this:

import sys
so = sys.stdout
sys.stdout = sys.__stdout__
from you_get import common as you_get
sys.stdout = so

nice，it works, 3Q!

This issue is fixed in Chaquopy 10.0.1. To upgrade, edit your app's top-level build.gradle file and change the version number of com.chaquo.python:gradle.
