Plots not working with Jupyter lab

[shakasom]

Unless i use offline mode explicitly, plots will not show up in Jupyter lab. But works fine with Jupyter notebook

[nicolaskruchten]

OK, I'll give this a whirl tomorrow! What versions of Python and JupyterLab are you using?

Also, what do you mean by "Unless i use offline mode explicitly" ?

@shakasom , hope this helps!

Run this in your jupyter notebook, or jupyterlab env, cell:

!pip install plotly_express

I posted reasons and such here:

I just meant initializing for offline plotting ... Plotly.offline.plot. In that case if i pass it to plotly_express object it will work.

Windows 10: Jupyterlab 0.35.3 and Python 3.6.6.
Ubuntu 18.04: Jupyter lab 0.35.4 and Python 3.7.2

Hi @shakasom ,

Rendering figures in JupyterLab using plotly.offline.iplot requires the @jupyterlab/plotly-extension extension. If you don't have this installed, give that a try and see if that helps.

Thanks @jonmmease . That fixed the issue.

HI, I have tried everything I could find over the internet to resolve this issue, but px still plots empty.

@DmitriyG228 can you tell me which command you're using to launch the Notebook, and which versions of Jupyter, the Jupyter extension, and Plotly and Plotly Express you are using?

When using jupyter notebook it sometimes happens that the notebook loses track of its state, in which case you unfortunately need to use the "restart & clear output" option from the Kernel menu in the notebook. JupyterLab doesn't suffer from this problem.

Hi, @nicolaskruchten ,

• My lab is running on remote server (Ubuntu 18.04.3),

• I launch server with /bin/bash -c "cd /path; source ~/.bashrc; conda activate base; (jupyter lab --ip=0.0.0.0 --port=9996 >> /var/log/jupyter2.log 2>>/var/log/jupyter2.log)" &

• i connect to jupyter server with dedicated domain name.

• jupyter lab version 0.35.4

• I am not very familiar with jupyterlab extensions and can not find how to check what is installed, but, I remember that I have installed @jupyterlab/plotly-extension and some other one.

plotly==4.0.0
plotly-express==0.4.0

Thank you!

[nicolaskruchten]

@DmitriyG228 ok thanks! I will definitely need the list of lab extensions, available by running jupyter labextension list... I suspect you have the old, pre-v4-compatible extension.

[DmitriyG228]

@nicolaskruchten , thank you and sorry for my noob knowledge of extensions

(fastai) dima@ml:~$ jupyter labextension list
JupyterLab v1.1.4
Known labextensions:
   app dir: /home/dima/anaconda3/envs/fastai/share/jupyter/lab
        @jupyterlab/plotly-extension v1.0.0  enabled  OK
        nbdime-jupyterlab v1.0.0  enabled  OK
        plotlywidget v0.8.0  enabled  OK

Build recommended, please run `jupyter lab build`:
    plotlywidget needs to be included in build

@nicolaskruchten, can you please look at my issue once again? you may have missed my last message. thank you!

[nicolaskruchten]

Sorry, yes. The output above suggests that the extensions aren't installing correctly, but I'm not sure why. I would recommend uninstalling and reinstalling the latest version of the extensions (which are 1.2.0 I think, today!)
