Hi,
After the upgrade to Jupyter 5.2.1 in Sage 8.2.beta0 (cf. #24168
<https://trac.sagemath.org/ticket/24168>), the export of a notebook to
another format seems broken. For instance, clicking on File -> Download as
-> PDF via LaTeX leads to
500 : Internal Server Error
The error was:
Could not import nbconvert: No module named base
In the console from which "sage -n jupyter" is run, we get the error
message:
[W 16:20:16.102 NotebookApp] 500 GET

On the same, computer, it is OK with Sage 8.1.
