1 AttributeError: can be defined as an error that is raised when an attribute 
2 reference or assignment fails.

1This happens because the scipy module doesn't have any attribute named sparse. That attribute only gets defined when you import scipy.sparse.
2
3Submodules don't automatically get imported when you just import scipy; you need to import them explicitly. The same holds for most packages, although a package can choose to import its own submodules if it wants to. (For example, if scipy/__init__.py included a statement import scipy.sparse, then the sparse submodule would be imported whenever you import scipy.)
