I am trying to compiled caffe with python3. After the compilation when I am trying to import caffe I am getting follwing error

```
In [1]: import caffe
Failed to include caffe_pb2, things might go wrong!

```

* The issue is Python 3 renamed the unicode type to str, the old str type has been replaced by bytes.

I tried to modify the proto/caffe\_pb2 but it is not working. 

Anyone having similar issue with caffe. I have a working caffe with python3 support in my bare metal Now I am trying to dockerize it.

Thanks in advance.
