I am following this guide (https://developers.google.com/protocol-buffers/docs/pythontutorial) and using the exact sample of addressbook.proto.
Post the content of compiler generated addressbook_pb2.py file as well. When I run the following simple program, there is error saying, cannot find google.protobuf, any ideas how to resolve this issue? Thanks.
BTW, using Python 2.7 on Mac OSX.
from addressbook_pb2 import Person
p = Person()
p.email = "abc"
print p.email
Here is the automated generated file addressbook_pb2.py,

Had the same issue and I resolved it by using :
conda install protobuf
