First of all. I am not sure if this is the right place to ask, probably not but I am hoping I am not the only one in a situation that I believe should be very common to many here.
The problem: I am using Anaconda and I have installed the ‘jupyter_contrib_nbextensions’ package in normal Jupyter Notebooks via conda. The good thing that it does all work fine.
Now, I want to keep some of the extension features also when using nbconvert to export to an html file. The read the docs for nbextensions does talk about it but if I am honest they seem very sparse and in any case I am getting some errors that I don’t understand and any help is appreciated.
I have made this very simple notebook and the only extension feature I would like to have when exporting to html is the collapsible headings. So I have tried the following:
jupyter nbconvert --to html_ch testexport.ipynb
I get the following error:
[NbConvertApp] WARNING | Config option
kernel_spec_manager_classnot recognized byNbConvertApp.
[NbConvertApp] Converting notebook testexport.ipynb to html_ch

i have tried to look around but could not really find much. Also:
jupyter --version
jupyter core : 4.7.1
jupyter-notebook : 6.3.0
qtconsole : not installed
ipython : 7.22.0
ipykernel : 5.3.4
jupyter client : 6.1.12
jupyter lab : not installed
nbconvert : 6.0.7
ipywidgets : not installed
nbformat : 5.1.3
traitlets : 5.0.5
Is it possible it is an issue with nbconvert? I would be really surprised if so. If I can give more information that is helpful to fix this I am here. It would really important for me, thanks.
