Shapely error when running first example

[filmartinelli]

Hello, I have just installed gdshelper on my python. I tried to run the first example on the tutorial, but it returns me the error "No module named 'shapely.topology'" Shapely is installed in my python and up to date and I checked that the other modules works. However, it seems that this topology module does not exist and I am not sure how to fix it
