cannot use in python2? 

when I use sqlalchemy-clickhouse in "hue"，i got error like follows:

Non-ASCII character '\xe2' in file /usr/share/hue/build/env/local/lib/python2.7/site-packages/infi/clickhouse_orm/models.py 

then, I delcare the utf-8 encode, however another error occurs.

so, sqlalchemy-clickhouse cannot use in python2? or I do somethong wrong?
