Description

I use my personal linux machine to run notebooks. Today, I tried to run regular "jupyter notebook" command, but got error log below. I already purged the jupyter content from my machine and also tried installing inside a virtual environment, running command without success. There is something other I am not trying.

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/notebook/traittypes.py", line 235, in _resolve_classes
    klass = self._resolve_string(klass)

    return import_item(string)

    module = __import__(package, fromlist=[obj])
ModuleNotFoundError: No module named 'jupyter_server.contents'

During handling of the above exception, another exception occurred:

Hi @brunolnetto thank you for opening this issue! It is an issue similar to what was previously reported, https://github.com/jupyter/notebook/issues/7054 as well as in the traitlets repo. There seem to be two possible solutions, either downgrading to a version of traitlets <= 5.9 or upgrading to Notebook >= 6.4.13. (Notebook 6.5 series would be >= 6.5.6). I will close this issue but if you would like to reopen this issue with any further questions or follow-ups please feel free to do so!

Thansk for answering. I removed traitlets==5.13.0 with command pip uninstall traitlets and reinstalled with command pip install traitlets==5.9. It worked like a charm. :3

did the same but still it isn't working

I'm finding the same issue; and also noting that recent ipyhton does want a more recent version of traitlets.

pip freeze | grep notebook notebook==7.1.2

Also:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. ipython 8.23.0 requires traitlets>=5.13.0, but you have traitlets 5.9.0 which is incompatible.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.

This behavior is the source of the following dependency conflicts. ipython==8.23.0 requires traitlets>=5.13.0,

the upgrade-traitlets installed to achieve compatibility appeared to cause problems.

Instead:

We removed traitlets==5.13.0 with command pip uninstall traitlets,

and reinstalled with command pip install traitlets==5.9.

It worked like a charm.
