I was able to temporarily fix that by using old version of jupyter_client:

jupyter_client==7.4.8

also getting this issue, and it continues to present after downgrading jupyer_client ... I have the following:

ipython==8.15.0
ipython-genutils==0.2.0
  
jupyter==1.0.0
jupyter-console==6.6.3
jupyter-events==0.7.0
jupyter-lsp==2.2.0
jupyter_client==7.4.8  # downgraded from 8.3.1
jupyter_core==5.3.1
jupyter_server==2.7.3
jupyter_server_terminals==0.4.4
jupyterlab==4.0.5
jupyterlab-pygments==0.2.2
jupyterlab-widgets==3.0.8
jupyterlab_server==2.24.0


notebook==7.0.3  # it looks like the issue is here??
notebook_shim==0.2.3

is this an issue with a notebook release?

running on Mac M1 Pro

I believe the issue is due to changes made in the recent quite large notebook version change from 6 to 7 and the accompanied API changes. More can be found here: https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html

./manage.py shell_plus --lab should also still work if jupyterlab is installed.

yes, --lab does work ... but its quite a jump -- this django-extensions should be updated for it, no?

I confirm what @chbroecker said. For me, it worked (keeping notebook version 6) using

notebook = "==6.5.4"
nbclassic = "*"

I solved the issue downgrading notebook with this command

pip install notebook==6.5.6

Then using the command

python manage.py shell_plus --notebook

work well for me.

PyCharm or VSCode can use Notebook 7 out of the box. For Django, I only need to set the project settings. This is a shame Notebook 7 cannot run from the terminal (it should open a browser)

import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"

There is a workaround. Instead of running ./manage.py shell_plus --notebook, you can run jupyter-lab command. It will open a new browser window. Now, to get access to Django context.

# First run:

import os, sys
import django

PROJECTPATH = '/path/to/your/djangoproject'
sys.path.insert(0, PROJECTPATH)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangoproject.settings")
os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"
os.chdir(PROJECTPATH)
django.setup()

# and now you can run any of your code, e.g.

from django.conf import settings
print(settings.DATABASES)

I had the same issue. I solved it by downgrading these packages:

notebook==6.5.4
traitlets==5.9.0
ipython==8.10.0
