Does autocomplete work for all paths in sys.path?

I added a set of python lib paths to sys.path, expecting pycharm to let me use autocomplete on those paths.

But, I am unable to do that.

For example:
I added "/prod/foo/lib/python/" to sys.path (under which I have a package "bar"), but autocomplete does not recognize "bar" when I try doing "import bar".

Could someone help?
Thanks!
