@mrachakonda

I have installed jupyterhub last week that time 4 pods were deployed. And when i installed today i am seeing only two pods hub and proxy.

I am installing python packages as below image:
name: jupyter/scipy-notebook
tag: latest

@consideRatio I have never heard about kon-chat place? what is it about?

Erik Sundell

@consideRatio

hahahahah well no clue, typo from mobile, hmmm, what did i mean? Ah! non-chat, so discourse / github

sanjaydatasciencedojo

@sanjaydatasciencedojo

@consideRatio No problem. Discourse seems to be right place for my question

Bolabx

@Bolabx

Is it possible to configure Nbconvert in a z2jh deployment? Where one can set such configs? Plz give any hint, clue...

Johannes Reppin

@belfhi

@Bolabx what do you mean with configure? Is it installed in your singleuser container?

Johannes Reppin

@belfhi

@mrachakonda can you start a singleuser server? It seems like your second deployment does not have continuous image puller enabled, are you installing the same release?

sanjaydatasciencedojo

@sanjaydatasciencedojo

We are using GCP managed Kubernetes to deploy Jupyterhub. What is a suitable tool for reporting errors and alert for that?

Jacob Alan Pawlak

@jakepaw

@sanjaydatasciencedojo im using prometheus with alertmanager
https://prometheus.io/docs/alerting/alertmanager/

Bolabx

@Bolabx

actually nbconvert was already installed and i just want to slightly change the default config. @belfhi. yes, it was installed via singleuser image.

@kdeepak99

Guys Can any one plz tell me how to change Python version from 3.7.5 to 3.8 in Jupyter?

Jacob Alan Pawlak

@jakepaw

@kdeepak99 you can create an IPython Kernel with that python version, or install nb_conda and create a conda environment that users can use to run 3.8

kdeepak99

@kdeepak99

@kdeepak99
Guys I am getting below error
Traceback (most recent call last):
File "/usr/local/Cellar/jupyterlab/1.2.0/libexec/bin/jupyter", line 6, in <module>
from pkg_resources import load_entry_point
ModuleNotFoundError: No module named 'pkg_resources'
while starting jupyter notebook

plz help me how to resolve issue

Johannes Reppin

@belfhi

@kdeepak99 how did you install jupyterlab? the path seems a little strange for a standard installation...

kdeepak99

@kdeepak99

i have installed thru pip

@belfhi

Does it works or need to reinstall

Johannes Reppin

@belfhi

well your path seems to be messed up

kdeepak99

@kdeepak99

any modification required?

kdeepak99

@kdeepak99

@belfhi Please let me know

Does Jupyter supports 3.8.0?

Johannes Reppin

@belfhi

@kdeepak99 I don't see why not^^ are you on macOS ?

are you using the right pip to install jupyter etc? Sometimes there's a system python pip and another one if you use something like homebrew

kdeepak99

@kdeepak99

i am using only pip

not homebrew

Johannes Reppin

@belfhi

I see, the path /usr/local/Cellar is a homebrew path though...

@kdeepak99 what does which python3.8 and which pip3 give you?

liujinjie26

@liujinjie26

I need to run R notebooks on JupyterHub, but the only available kernel I see is Python3. Can you help me guiding me how to install the R Kernel in JupyterHub?

Juan Pablo Lopez

@juanpalopez

Hello, Anybody has experience deploying jupyterhub with fargate spawners

Wayne's Bioinformatics Code Portal

@fomightez

@liujinjie26 I haven't done it myself on a JupyterHub but when asked about adding Python 3.8 a few days ago, @jakepaw responded: "@kdeepak99 you can create an IPython Kernel with that python version, or install nb_conda and create a conda environment that users can use to run 3.8". I note on the page here concerning the 'nb_conda' that it mentions R is possible as a choice of base environment under Creating New Environments. And so that may be a route?

Jacob Alan Pawlak

@jakepaw

@fomightez Yes I believe that is one way that you could do it. Using nb_conda has been successful for me.

Wayne's Bioinformatics Code Portal

@fomightez

Thanks for letting us know it should be a viable route. I think the kernel installing route is covered here.

@scuddalo

Hello everyone, I am new to jupyterhub. I would like to deploy a custom singuser image with a c.NotebookApp.contents_manager_class that writes to s3. Is that valid?

I have created a custom image and while jupyterhub serves it somehow the s3 content_manager_class is not getting activated

scuddalo

@scuddalo

Ok, I figured out the issue. I was writing the config from my custom image to $HOME and jupyterhub was mounting a volume in home. so I was losing my config. Moving my config to /etc/jupyter made everything ok.

Murali Rachakonda

@mrachakonda

@scuddalo did you install using helm or without helm.

scuddalo

@scuddalo

helm

is there some configuration to avoid mounting a volume? @mrachakonda

Murali Rachakonda

@mrachakonda

when you install with helm you just pass config.yaml. I am not clear what you meant by config from custom image. I am also new to jupyterhub and just trying to understand.

scuddalo

@scuddalo

@mrachakonda I meant I built a custom singleuser docker image and set it in helm config.yaml using singleuser.image.name. When Jupyterhub creates for a single user it it mounts a volume created for a user under home directory... essentially wiping out everything I put in my image's home directory

JoranDox

@JoranDox

is it possible to scp files to & from a jupyterlab? or are there better migration options (running on azure) ?

Yuvi Panda

@yuvipanda

I drafted a little blog post on connecting to JupyterHub from your local vscode. https://medium.com/@yuvipanda/connect-to-a-jupyterhub-from-visual-studio-code-ed7ed3a31bcb thoughts welcome! I'll probably publish it later today

Ian Rose

@ian-r-rose

Very cool trick, Yuvi

Yuvi Panda

@yuvipanda

thanks, @ian-r-rose

Medium doesn't let you put images inside lists, which is ridiculous

Ian Rose

@ian-r-rose

One clarification question: will that automatically start the server if it is not running?

Yuvi Panda

@yuvipanda

@ian-r-rose ah, good question. Let me test that out, my intuiton is 'no'

@ian-r-rose yep, won't. added as a limitation
