Config option `template_path` not recognized by `LenvsLatexExporter`. Did you mean one of: `template_file, template_name, template_paths`?

Several warning messages like the present are shown whenever I open any notebook from jupyter.
I have disabled jupyter_contrib_nbextensions and then uninstalled them.

In all cases, warnings are shown, like in:

I forgot to mention that even after disabling and/or uninstalling, the warnings continue to show.

I have the exactly same problem.

While looking for possible causes, I found one thing:

• when I downgraded from nbconvert 6.0.3 to 5.6.1, issues are gone - warning are gone and exports started working again
  • use conda install "nbconvert=5.6.1"
• this probably means, that nbconvert >= 6.00 has significant changes - see here: https://nbconvert.readthedocs.io/en/latest/changelog.html#significant-changes
  • one specially interesting is: template_path has become template_paths - maybe this can be related with the issue

I forgot to mention that even after disabling and/or uninstalling, the warnings continue to show.

One more thing to add, that exports from menu File -> Export Notebook As... are also failing.

I have the same issue. After several days to working the annoying problem, deleting and reinstalling, they wont go away. I found this thread when I wanted to open a new issue, so thanks guys for the work around.

Edit: it looks like @stefansimik already said this

I just figured this out.

It has to do with the fact that nbconvert 6.0 changed template_path to template_paths. Until this project changes that you should require nbconvert<6.

This fixed it for me.

[stefansimik]

I am not sure, where change should happen / what project should be updated...

• if nbconvert should rollback its changes
• or other projects depending on nbconvert should update and get in sync with nbconvert

I had the same error and downgrading nbconvert to 5.6.1 helped prevent these errors when running jupyter notebook.
HOWEVER, I am still having trouble with nbextensions. When I open a notebook that previously used to successfully have a table of contents, I am now getting an error:
404 GET /nbextensions/widgets/notebook/js/extension.js?v=20200928130405 (::1) 8.80ms referer=http://localhost:8889/notebooks/Figures.ipynb
(Figures.ipynb is the notebook I am trying to run).
And there is no longer a table of contents tab/option in the notebook (though the collapsible headings seem to be working).

I have searched around for a while now and still no success. Any ideas/help?

Thanks!

UPDATE: the table of contents does show up for a different notebook.
The notebook that it is not showing up in has been the one that I have been mainly using TOC (successfully) in until today.

Just in my case - I can say, that TOC extension (https://github.com/jupyterlab/jupyterlab-toc) was working correctly all the time, i.e. even before downgrading nbconvert back to v5.6.1
That's why I am not sure, if problem in TOC is directly related to bad version of nbconvert ...

[demotu]

Yes, this issue is related to the change in Nbconvert that replaced 'template_path' with 'template_paths'.

Replacing all instances of 'template_path' with 'template_paths' in the extensions jupyter_latex_envs and jupyter_contrib_nbextensions fixes the error.

I opened pull requests with these changes:
jfbercher/jupyter_latex_envs#58
#1532

If you want to get rid of the error messages before the extensions update, install the extensions from my repos (or clone them) or just replace 'template_path' with 'template_paths' in the local folders of these extensions (in my case these extensions were in ~/miniconda3/lib/python3.8/site-packages/...)

If you want to manually replace all instances of 'template_path' in the files, you can use an editor such as Visual Studio Code or PyCharm. For example, in VS Code:

1. Use the menu option 'File/Open Folder...' to select the desired folder ('jupyter_contrib_nbextensions', 'jupyter_latex_envs' or 'latex_envs').
2. Use the menu option 'Edit/Replace in Files' and type 'template_path' and 'template_paths' in the text boxes (without quotes) to replace all occurrences.

I have encountered the same problem. Has anyone solved it now?
