Export Table of Contents from Jupyter Lab to a Cell

Question

• How can all of the jupyter nbconvert export options be enabled from the Export Notebook As... menu in Jupyter lab?
  • Specifically, how can I get the option to Export Notebook to Html_toc on the menu?
• Following a clean installation of Anaconda, the default export menu is:
  • 
• However, as shown in this issue Add nbconvert export options to File --> Export notebook as #7612, there are additional options, which can be run from the console, but do not display in the menu.
• The full menu would look like:
  • 

Answer 1

• This answer is a roundabout hack for enabling the full menu in Jupyter Lab
• In this situation, I have a clean installation of Anaconda, which includes Jupyter Lab and Jupyter Notebook.
• Upon entering Jupyter Lab, only the minimal Export options are available.

To enable the Html_toc Export option, do the following

1. Go to the Extension Manager in Jupyter Lab and install @jupyterlab/toc
   • 
   • Current versions of Jupyter Lab already have the TOC, so this step may not be necessary.
2. Shut down Jupyter lab and go to the Anaconda Prompt
3. If your version of nbconvert is greater than 5.6.1, then do conda install -c conda-forge "nbconvert=5.6.1"
4. Run conda install jupyter_contrib_nbextensions or conda install -c conda-forge jupyter_contrib_nbextensions per Installing jupyter_contrib_nbextensions Guide.
   • This will install a number of extensions to \\Anaconda3\\lib\\site-packages\\jupyter_contrib_nbextensions\\nbextensions\\
   • There are pip install options in the guide, but I haven't tried this for a manual installation of Jupyter Lab and Jupyter Notebook
5. Run jupyter contrib nbextension install --user
6. From the Anaconda Prompt, run jupyter notebook
   • During loading of the Jupyter Notebook environment, there where warnings as follows [jupyter_nbextensions_configurator] nbextension '...' has duplicate listings.
   • One location was \\Anaconda3\\..., as mentioned above, and the other was \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions\\...
   • This could be because I had a previous installation of Anaconda, but I resolved this issue by renaming \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions\\... to \\Users\\...\\AppData\\\Roaming\\jupyter\\nbextensions_old\\...
7. Go to the Nvextensions tab, select the option for Table of Contents (2), and Enable it.
   • 
8. Quit / Logout of Jupyter Notebook
9. From the Anaconda prompt, go the jupyter lab
10. Now all of the Export Notebook As... options will be enabled in the file menu.
    • Including, and specifically Export Notebook to Html_toc

Examples

• Here are examples of HTML notebooks with a Table of Contents output from Jupyter Lab. See the DataCamp notebooks.
