python-gui raises exception on launch

[dnyaneshgate]

I am using Ubuntu-16.04 Gnome3. Python-GUI installed using 'pip install neovim-gui'

Getting following exception on running command pynvim

I am using Ubuntu Gnome 17.04. When I try to run pynvim from the terminal, a window appears for a seccond. And this is the output from the terminal.

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/neovim_gui/ui_bridge.py", line 97, in apply_updates
    handler(*args)
TypeError: _nvim_mode_change() takes 2 positional arguments but 3 were given

I have installed python-gui using sudo pip install neovim-gui

This repo is not really active developed. Maybe https://github.com/rliang/nvim-pygtk3 works better?
