Hi @brunolnetto thank you for opening this issue! It is an issue similar to what was previously reported, #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! |

############################################################################################## 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. |
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.

Server startup and open browser tab with jupyter UI.
