jupyter nbconvert broken

[Pstrang Rzekle]

I'm unable to use nbconvert from the command line or from within the jupyter notebook.

[user@host ~]$ jupyter nbconvert --to latex test1.ipynb --log-level=DEBUG

Thank you for any suggestions!

How did you instal Jupyter? Why is it in /home/mitchw/Downloads?

[Pstrang Rzekle]

After trying numerous things and not having any luck with the "sage-8.0-Fedora_25-x86_64.tar", I tried nbconvert from github: https://github.com/jupyter/nbconvert.

Still didn't work, so I have since uninstalled it (sudo pip uninstall nbconvert), and reinstalled the pip version (sudo pip install nbconvert).

No difference in results, same error from the command line. :(

Can you try starting nbconvert from Sage rather than from the system's jupyter?

That is, starting sage with -n command line option will bring up nbconvert.

$ sage -n

Please wait while the SageNB export server starts...

[user@host ~]$ sage -n jupyter

The above starts a jupyter notebook correctly.  After installing some additional packages, I can now "Download as.../PDF via LaTeX (.pdf)" correctly.  Yea!

However, after using "%display latex" in the notebook, the equations are still rendered as text in the PDF, not LaTeX as they are displayed in the notebook.

This is the reason for trying to use the command-line to generate the LaTeX so I can use other tools to generate actual LaTeX equations from the notebook.

Thank you!

Also, just noticed that the jupyter notebook apparently isn't flushing old versions of the notebook before converting to PDF via LaTeX.  A major change and re-saving of the notebook still generates the old PDF.  Exiting and restarting the jupyter server still keeps the old notebook version to generate the PDF.  The only fix I found required me to give the notebook a new name to generate an updated PDF.  :(
