Please follow the example written in
ryu/app/gui_topology/gui_topology.py and execute from the top level
ryu directory, such as:

     $ PYTHONPATH=. ./bin/ryu run \
       --observe-links ryu/app/gui_topology/gui_topology.py

Without a directory component, its line 37 doesn't work and I guess
you are having 404 errors.
