问题
The toolbar and notebook name does not show when I call and load the themes from the notebook.
I can load the themes from notebook using a code but I am not sure how to use the switches like -T and -N for call to toolbar and notebook name.
I have used the following in a code cell:
from jupyterthemes import get_themes
import jupyterthemes as jt
from jupyterthemes.stylefx import set_nb_theme
set_nb_theme('solarizedd')
The theme changes but the toolbar and notebook name does not appear. Even using the Toggle Header and Toggle Name from view in menu bar has no effect.

I just installed the jupyter themes and went thru the same issue. My regular and nbextension toolbar disappeared and could not make it come back unless I reverted to default !jt -r.
after some research i fugure it out....so your cell should write
from jupyterthemes import get_themes
import jupyterthemes as jt
from jupyterthemes.stylefx import set_nb_theme
set_nb_theme('solarizedd', -T, -N,-kl)
- Toolbar Visible -T
- Name & Logo Visible -N
- Kernel Logo Visible -kl
- their defaults are set to none
see the documentation documentation of jupyter theme
or something more permanent and fewer lines of code, using the command "!" in the actual cell
!jt -t solarizedd -T -N -kl
回答2:
jt -t oceans16 -T -N
this would surely help.

Have you tried to update to the latest version? I have tried many suggestions. All did not work until I updated the theme package to the latest version
pip install --upgrade jupyterthemes
I found the solution here

I was able to solve this by editing the custom.css file located at ~/.jupyter/custom/custom.css. I changed the mailtoolbar setting from ’none’ to ‘block’. i.e. find this line:
div#maintoolbar {
display: none !important;
}
...and change it to:
div#maintoolbar {
display: block !important;
}
Hope that works for you too! Don't imagine looking for reasons it failed to start with, however, there is a theory one cannot update while it is running.
