jupyter notebook cannot use osx backend (matplotlib)

jupyter notebook cannot use osx backend (matplotlib).

I have had this problem on and off over many versions of osx, and usually it was related to virtual envs. I now use python3 venv, python: 3.6.1 jupyter-client (5.1.0) MacOS: HighSierra

if I attempt to use the osx backend in a notebook (%matplotlib osx), no error is emitted, and no window or figures are opened or shown when plotting. jupyter console fails with the message: ERROR:tornado.application:Exception in callback functools.partial(<function wrap..null_wrapper at 0x1049bbea0>) Traceback (most recent call last): File "/Users/Shared/py3.6.1/lib/python3.6/site-packages/tornado/ioloop.py", line 605, in _run_callback ret = callback() File "/Users/Shared/py3.6.1/lib/python3.6/site-packages/tornado/stack_context.py", line 277, in null_wrapper return fn(*args, **kwargs) File "/Users/Shared/py3.6.1/lib/python3.6/site-packages/ipykernel/kernelbase.py", line 265, in enter_eventloop self.eventloop(self) File "/Users/Shared/py3.6.1/lib/python3.6/site-packages/ipykernel/eventloops.py", line 277, in loop_cocoa show.mainloop() AttributeError: 'function' object has no attribute 'mainloop' Using matplotlib backend: MacOSX

switching to inline or another backend does work, but I want the interactive control in osx.

I think this should be fixed by https://github.com/ipython/ipykernel/pull/290 . That will be released as ipykernel 4.8.
