[gentoo-user] jupyter notebook 500 : Internal Server Error

[gentoo-user] jupyter notebook 500 : Internal Server Error

[Valmor de Almeida]

Hello,
I had to enable ~amd64 to emerge jupyter so I know this is bound for
problems. However, anyone there able to use jupyter notebooks in
gentoo?
No matter what notebook I try to open, I get the internal server error.
Thank you.

Not much help, but I have not had problems with jupyter for years, with
~amd64 profile.

I isolate jupyter (actually jupyterlab) in an separate python 
environment. I do use pipenv to manage the python environment. It boils 
down to three commands:

$>  cd projectfolder
projectfolder $>  pipenv install
projectfolder $>  pipenv shell
projectfolder $>  pipenv install jupyter-lab

pipenv itself can be installed with emerge. pipenv resolves the 
dependencies within the virtual python environment.
This way of working with python solved most of my troubles with ~amd64 
python packages. python packages for system and for programming purposes 
stay separate this way.

Do you have this issue when you run jupyter from a virtual environment?

Try updating dev-python/nbconvert to a version newer than the stable one.

You probably did this the same way as me, keywording only what was really 
necessary on an otherwise stable system. Problem is, notebooks have an 
internal versioning, and nbconvert-5.2 doesn't support recent versions 
anymore. After updating nbconvert things worked fine for me.

(Time to fix this, I know, but there's only so many hours in the day...)
