many warnings about Config option template_path not recognized by

[joernhees]

after a recent upgrade, whenever i open a notebook i am spammed with warnings on the terminal from which i started jupyter notebook:

My guess is that some config option template_path was changed to template_paths in some project, but not (yet?) adapted in a related... maybe this has to do with some of the extensions i'm using, but even removing ~/.jupyter and reinstalling them with the following didn't help:

jupyter contrib nbextension install --user
jupyter nbextensions_configurator enable --user
jupyter nbextension enable toc2/main
jupyter nbextension enable collapsible_headings/main
jupyter nbextension enable highlight_selected_word/main
jupyter nbextension enable execute_time/ExecuteTime

The only mention of template_path i can find is in ~/.jupyter/jupyter_nbconvert_config.json, but changing that to template_paths and restarting jupyter doesn't solve the problem either.

Any ideas where to look?

Looks like template_path was renamed to template_paths by this nbconvert PR which appears in nbconvert 6.0. Seems like renaming template_path to its plural form is the correct change to make (as shown in this more recent PR), so I would suggest opening this issue in nbconvert.

[kevin-bates]

I'm going to close this issue. If we find that there's some kind of change needed in this repo, we will be happy to reopen it at that time.

I am getting this same error. Does not seem like an nbconvert thing, but rather an nbextensions thing?

[kevin-bates]

Good point - thanks for the hint @neurologic.

Looks like a number of the exporters in jupyter_contrib_nbextensions reference the template_path trait of nbconvert. I suspect these warnings are visible if one has installed jupyter_contrib_nbextensions and would suggest the issue be opened in that repo - and, in fact, see that an issue already exists.

Thanks! I posted in the issue thread that you linked me to.
