Comment (by albcn):

 This bug has been here for several weeks.

 To me, editing (for 3.11, modify your version).

 {{{
 /opt/local/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11
 /site-packages/notebook/traittypes.py

 }}}


 And manually  changing

 {{{
 from traitlets import ClassBasedTraitType, Undefined, warn

 }}}

 to


 {{{
 from warnings import warn
 from traitlets import ClassBasedTraitType, Undefined

 }}}

 makes it work. This looks better to me than installing the package via
 pip.

 {{{
 pip uninstall traitlets
 pip install traitlets==5.9.0
 }}}
 as mentioned in other reports.
