python>import caffe throws: AttributeError: 'module' object has no attribute 'bool_'

Importing caffe throws the above error:

i checked on github and this https://github.com/BVLC/caffe/issues/782
 suggested that

As a rule of thumb, do not invoke python in a module's source file folder - instead, go to a different folder like $HOME/research/mycode, and add caffe/python into your PYTHONPATH.

Now at the start i had my path set as $HOME/caffe/python/caffe . then changed to >  $HOME/caffe/python/ but taking under consideration above i created another folder and set the path as
$HOME/path/caffe/python/
but still getting the same error.

How do i overcome this?
