module 'atom' has no attribute 'AtomBase' #8

Hi, i have atom version 0.4.1, jupyter notebook version 5.4.0. And have attribute error while importing the gdata module? What's wrong with it? with me?

`AttributeError Traceback (most recent call last)

1 import gdata.data
2 import gdata.gauth
----> 3 import gdata.contacts.client
4 import gdata.contacts.data
