I had no problem running jupyter nbconvert from the command line with Python 3.10.2. I installed Python 3.11.4 (through pyenv) and now I get the following error message:

jupyter --version gives me:

I’ve reinstalled ipython, notebook, jupyterlab and nbconvert (through pip) and I still get the same error message. When I switch back to Python 3.10.2, everything works fine again.

Any help would be appreciated!

Hi ctl360,

did you solve this issue? I go back from 3.11.7 to 3.10.11 on my M$ Win 11 but still get the same error

Also a “simple” jupyter contrib leads to

Do you know a solution?

Thanks a lot!

Hi thanks a lot. I tried only uninstalling jupyter_contrib_nbextensions which leads to the issue that jupyter-contrib-core fails. But, and this was my fault, I didn’t uninstall jupyter-contrib-core ! However, I solved the “problem” (whereby I was the problem ;-)) in that way that I uninstall (with pip) all packages and add by hand (with pip install) all needed stuff for my work. What I can see, my now working “setup” has the following jupyter and nb* / notebook stuff:

jupyter 1.0.0
jupyter_client 8.6.0
jupyter-console 6.6.3
jupyter_core 5.7.1
jupyter-events 0.9.0
jupyter-lsp 2.2.2
jupyter_server 2.12.5
jupyter_server_proxy 4.1.0
jupyter_server_terminals 0.5.2
jupyterlab 4.0.11
jupyterlab_pygments 0.3.0
jupyterlab_server 2.25.2
jupyterlab-widgets 3.0.9

nbclient 0.9.0
nbconvert 7.14.2
nbformat 5.9.2
widgetsnbextension 4.0.9

notebook 7.0.7
notebook_shim 0.2.3

for jupyter I use pip install jupyter[all]

Thanks again for your help, I assume this will help, but as written I didn’t test it

nbconvert 7.16.2
jupyterlab 4.1.4

ModuleNotFoundError: No module named ‘jupyter_contrib_nbextensions’

When running

jupyter nbconvert --to latex .

I cant not find jupyter_contrib_nbextensions dependency on

Installation — nbconvert 7.16.2 documentation .

Moreover search for jupyter_contrib_nbextensions on the whole space does not return any resuls.

Where this package is comming from?

I’m still able to conver ipynb to latex in jupyter lab , what is not that convenient for automation.

Any updates / hints?

Thank you,
Sergey

I have the same problem. I’m creating an environment from scratch, using a requirements file that used to work, but it seems like the latest version of jupyter and nbconvert are not getting along.

I’m stumped for now – I hope someone figures it out soon!

Sergey_Hein:

search for jupyter_contrib_nbextensions on the whole space does not return any resuls.

It probably shouldn’t return any results looking for that in your system space. jupyter_contrib_nbextensions is the old Jupyter Notebook unofficial, user-contributed extensions, see here . It isn’t pertinent to JupyterLab 4. Or now Jupyter Notebook 7+.

Do you have any old stuff around interferring?

For example here someone had a file jupyter_nbconvert_config.json . Similar reports elsewhere in that thread . Maybe investigate in those highlighted locations?

Or here someone had to uninstall some one packages. Note that there someone says much along the lines of what I said at the start of this post.

There was a report a few years ago that the environment was picking up configuration from the system Python here .
It was basically old stuff interfering though, as I discussed in my reply to Sergey.

HI @fomightez , now I’m confused even more.
Do I need to install nbconvert?

Here are my dependencies ( extract from pyproject)

[tool.poetry.dependencies]

python = “~3.11”

numpy = “^1.26.3”

scipy = “^1.11.4”

matplotlib = “^3.8.2”

pandas = “^2.1.4”

nltk = “^3.8.1”

sympy = “^1.12”

jupyterlab = “^4.0.10”

pandera = “^0.18.0”

polars = “^0.20.5”

itables = “^1.6.3”

black = {extras = [“jupyter”], version = “^23.12.1”}

quantstats = “0.0.62”

cufflinks = “^0.17.3”

sqlalchemy = “^2.0.25”

statsmodels = “^0.14.1”

pyarrow = “^15.0.0”

nbconvert = “^7.16.2”

fitz = “^0.0.1.dev2”

frontend = “^0.0.3”

pymupdf = “^1.23.26”

chardet = “^5.2.0”

Can you suggest based on avove what I’m doing wrong.

Thank you,
Sergey

I see JupyterLab 4 and that is fairly new and different than older tech you may have had on your machine. If you didn’t start with only installing that it is easy to have other things around that could be messing things up.
The main point in my reply was that you may have old things interfering and should look for those and deal appropriately.
