Hi Gianluca,
It looks like that function is not available with pycairo for Python3:
http://cairographics.org/documentation/pycairo/3/reference/surfaces.html#cairo.ImageSurface.create_for_data
It is (or should be) available in cairocffi:
https://pythonhosted.org/cairocffi/api.html#cairocffi.ImageSurface.create_for_data
If both pycairo and cairocffi are installed, the code will prefer cairocffi
with python3.
