[IPython-dev] IPython 5.0 and ConfigManager issue

[Damián Avila]

Just to add a little bit more of info... if you are using RISE master and
notebook 4.2.1, you probably need something like this if you have them
installed in an environment:

from traitlets.config.manager import BaseJSONConfigManager
path = "/home/damian/miniconda3/envs/rise_latest/etc/jupyter/nbconfig"
cm = BaseJSONConfigManager(config_dir=path)
cm.update('livereveal', {
    stuff...
})

where rise_latest is the environment where you have RISE + notebook
installed...

Alternative, to customize the presentation you can also use the notebook
metadata... I will be releasing a RISE 4.0.0 beta soon... where some issues
loading customization from the metadata are solved.
So you can try customization on the fly... without restarting the notebook
server nor reloading the page.
