so now this works:

to_accordion(some_content,'some_title')

However having this in a for loop does not output anything. For example:

for i in range(3):
    to_accordion(i,i)

Do I have to output this in a different way in Jupyter maybe?

@minrk

You need to call display on the result

Ah you are right!!

please forgive my ignorance but if I want to re-run a cell and all the cells below it , I mark all the cells with Shift + End (starting from the cell I want to re-run) and hit ctrl+Enter . There must a better way right ?

hello. i'm trying to persist some value programmatically directly into the notebook. is this somehow possible? using %store et. al. wouldn't work as this is using the global namespace of the kernel, i guess. my goal is to carry that notebook around and be able to execute it w/ the serialized (once agreed upon and saved) parameters

thought there should be some programmable way to add something to the nb's metadata using get_ipython() or something

Min RK

@minrk

The kernel doesn't generally have access to any information about the document. The simplest way to 'store' such things as input variables is as assignments in a code cell

See some tools like nbparametrize that attempt to automate this process

Hi, I am running a jupyter server via conda, on a system that has also other jupyter installations.
How can I avoid my conda-jupyter to pick-up the system kernels ?
jupyter path shows me:

massimods@r740-5hdn2s2-ag-gcompute:~$ which jupyter
/modules/centos7/user-apps/fou-fd/miniconda-mds/envs/rapids-0.19/bin/jupyter
massimods@r740-5hdn2s2-ag-gcompute:~$ jupyter --paths
config:
    /home/massimods/.jupyter
    /modules/centos7/user-apps/fou-fd/miniconda-mds/envs/rapids-0.19/etc/jupyter
    /usr/local/etc/jupyter
    /etc/jupyter
data:
    /home/massimods/.local/share/jupyter
    /modules/centos7/user-apps/fou-fd/miniconda-mds/envs/rapids-0.19/share/jupyter
    /usr/local/share/jupyter
    /usr/share/jupyter
runtime:
    /home/massimods/.local/share/jupyter/runtime

I'd like to avoid to load all the system directory: /usr/local and /usr/share
Is it something that I can tune in the jupyter configuration?

massimods@r740-5hdn2s2-ag-gcompute:~$ jupyter kernelspec list
Available kernels:
  rapids     /home/massimods/.local/share/jupyter/kernels/rapids
  python3    /modules/centos7/user-apps/fou-fd/miniconda-mds/envs/rapids-0.19/share/jupyter/kernels/python3
  bash       /usr/local/share/jupyter/kernels/bash
  ir         /usr/local/share/jupyter/kernels/ir
  python2    /usr/local/share/jupyter/kernels/python2

Can someone help me enable horizontal scrolls to this :

from IPython.display import display
from ipywidgets import Output, VBox, Accordion, Layout

layout = Layout(border='solid blue')


def to_accordion(content, title):
    out = Output()
    accordion = Accordion([out], selected_index=None, layout=layout)
    accordion.set_title(0, title)
    with out:
        display(content)
    return VBox([accordion])


if __name__ == '__main__':
    to_accordion('test_content', 'test_title')

layout = Layout(border='solid blue', overflow_x='auto') didn't help

Anyone know if this is a place to ask questions about nbconvert or is there a different place for that (in gitter)?

Is the rich display system not implemented for JSON rendering in notebook, but only in jupyterlab?

Here is the full description jupyter/notebook#5446

Martin K. Scherer

@marscher

OK, the displaying is done by this extension, which is only available for jupyterlab: https://github.com/jupyterlab/jupyterlab/tree/master/packages/json-extension Do you think this could be ported for jupyter notebook as well?

hello guys, i cannot use jupyter because my kernel keeps dying non stop... do you know what it can be? i have been searching on online pages for days now...

Kevin Bates

@kevin-bates

Hmm - this is usually an indication that your kernel can’t complete its startup. However, we should be seeing the restart counts incremented, where after 5 attempts it gives up. Given the restart count is not incrementing is this continuing until the server is stopped?
Can you add DEBUG logging when starting the server (e.g., jupyter notebook —debug) and see if that produces any helpful information? In particular, the logging surrounding the command used to launch the kernel.

Hi Kevin, thanks! I've done that:

Kevin Bates

@kevin-bates

Have you tried taking the pieces of the Starting kernel array and invoking them from the command line? I suspect that might provide the reason ipykernel_launcher isn’t remaining running?

inesrgaspar

@inesrgaspar:matrix.org

[m]

How should I do that? Sorry, I am a beginner!

Kevin Bates

@kevin-bates

Since you provided an image rather than a textual representation, its a little cumbersome, but you’d basically invoke something like this: "C:\Program Files\python.exe" -m ipykernel_launcher -f "C:\Users\Ines Gaspar\AppData\…\kernel_….json” with the space-separated paths in double quotes (if I recall from my WIndows days)

Hello again...

"NOTE: When using the ipython kernel entry point, Ctrl-C will not work.
To exit, you will have to explicitly quit this process, by either sending
"quit" from a client, or using Ctrl-\ in UNIX-like environments
To read more about this, see ipython/ipython#2049
To connect another client to this kernel, use:
--existing C:\Users\Ines Gaspar\AppData\Roaming\jupyter\runtime\kernel-87c47cb4-88f5-4484-a584-7910c0e610bb.json"

Kevin Bates

@kevin-bates

ok. looks like the kernel can start. You’ll want to terminate this using ctrl-\.
Since this is proving difficult and you’re a beginner, troubleshooting can be a bit like groping in the dark. As such, I suggest we move this more to direct DM and can circle back with questions or a resolution later.
If others have a good way to troubleshoot these kinds of issues, it would be helpful. We should also determine if the kernel process is dying on first execution or not. Before moving to DM, are you able to attempt the execution of any cells?

Hi, is there a way to determine the current port from within the notebook?

@marscher

port = os.environ.get('SERVER_PORT', '')

Hello,
Does anyone know if it's possible to extract all attachments from a jupyter notebook and save them as distinct files?
When I try converting to markdown or html it outputs the links as attachment:foo.png instead of exporting the image

@sanjubaba1984_twitter

hello,
How we can download the output like we have options with databricks notebooks? is there any option in jupyter notebook to download the output??

Gilbert Brault

@gbrault

@dcompoze you may use nbconvert to export a notebook to html and then use beautifulsoup to edit the html file and get the attachments

os.system(f'jupyter nbconvert {report}.ipynb --no-input --to html')

I used that to create an automated outline of the notebook getting all the a html tags with beautifulsoup .
Open the html file to see where the attachements are encoded

@sanjubaba1984_twitter

hello,
How we can download the output like we have options with databricks notebooks? is there any option in jupyter notebook to download the output??

Like we have options to download the output in csv etc., is that same options present in jupyter notebook from where we can download the output?

Anyone please?

Hi all, just wonder is there any way that could let me get the notification for cell completion, I tried https://github.com/ShopRunner/jupyter-notify, but got a Javascript Error: $ is not define and had no idea how to resolve this...

and the jupyter was set up in a docker

Hi all. I am trying to create a notebook extension that will change the header of the notebook. That means it will show some pretty colors, some Icon, a user name and some other buttons etc. Now this extension needs to have both server extension and front end extension. I know how to create a server extension in Jupyter as there are enough documentation available for it. So assume that i have created a new handler at "/hello". Now how do I send GET request to that endpoint from a notebook extension(from the main.js basically) ?

@fomightez

Anyone got a fix or good workaround for the drop-down arrow for collapsible sections in markdown made by details/summary tags no longer working in classic notebook interface? (It works find in same browser in current JupyterLab.) See here if you have a solution? I think I found and linked to the filed issue jupyter/notebook#2223 that is related to this; however, feel free to point out if there is indeed a better one. Since this works in JupyterLab now and the underlying workings will soon be much more the same in notebook 7.0, maybe that is how it will be sorted?
