dogpile.cache 'No module named fcntl' error

Question

I'm using Python 2.7 with SQLAlchemy. I'm trying to see if I can use Dogpile.Cache. I've installed dogpile cache using

pip install dogpile.cache

but when I try to run the example given by SQLAlchemy (helloworld.py) I keep getting ImportError: No module named fcntl. I thought the newest Dogpile.Cache resolved the windows issue...

Could someone please help? Thank you.

UPDATE

Ok, the example is creating the database and cache. But when it is trying to load data using FromCache it is giving me an error.

people = Session.query(Person).options(FromCache("default")).all()

Here is the Traceback
