Not found `.tex` file on jupyterhub+jupyterlab about jupyterlab-latex HOT 10 CLOSED

Hi @epifanio what version of jupyterlab-latex, jupyterhub, jupyter notebook & jupyter lab are you using?

from jupyterlab-latex.

Hi @mpacer , I'm running jupyterlab and jupyterlab-latex from github master. hub and notebook are pip installed.

• Edit: I just updated jupyterhub to master, I'll do the same with the notebook and check again the jupyterlab-latex logs.

• Edit2: jupyterlab-latex, jupyterhub, jupyter notebook & jupyter lab are now updated to their git master branch versions. (Note: I've also installed jupyterlab hub extension, which was not installed before).

The jupyterlab-latex logs are the same (can't find .tex file)

from jupyterlab-latex.

could you pip install jupyter_conf_search and then run

jupyter_conf_search base_url

?

from jupyterlab-latex.

it gives me:

 jupyter_conf_search base_url
/root/.jupyter/jupyter_notebook_config.py
78: ## DEPRECATED use base_url
84: #c.NotebookApp.base_url = '/' 

I run the hub as root with a custom config which is in:

/etc/jupyterhub/jupyterhub_config.py

 cat /etc/jupyterhub/jupyterhub_config.py  | grep base
#  Dict of token:username to be loaded into the database.

Where do you define the root directory for the users of your jupyterhub cluster?

from jupyterlab-latex.

In my config I have:

c.Spawner.notebook_dir = '~/notebooks'

from jupyterlab-latex.

Ah… so that's the problem. I think that notebook_dir is being used there and we're looking for base_url on the notebook application.

@minrk which of these should actually be used for our purposes? @ian-r-rose said he had gotten the approach to use webapp.settings['base_url'] from jupyterlab (I think? Ian can you verify that?) so I'm not sure how this differs from that case.

from jupyterlab-latex.

base_url is only used as a prefix to all URLs in the webapp. It shouldn't be involved in locating files, however it is necessary when receiving a URL to not consider the base url part of the path to the file.

Notebooks are served from NotebookApp.notebook_dir, not necessarily the CWD, which is my guess as to the source of your issue.

You can test with:

jupyter notebook /path/to/some/dir

and see if it is locating files correctly

from jupyterlab-latex.

@minrk is there a way to get access to the notebook traitlets without needing to inherit the entire NotebookApp?

from jupyterlab-latex.

Fixed by #55, thanks for the report @epifanio
