TypeError: init() got an unexpected keyword argument 'inputhook'

See original GitHub issue

I updated all my Python packages this morning and IPython doesn’t work anymore since then. Error:

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@python.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
