hi, i tried running voila gridstack but i'm unable to do so, some assistance will be greatly appreciated !

Hi @tyxnna! Which version of voila and voila-gridstack are you using? The problem seems to be that voila can't find the voila-gridstack template. See jinja2.exceptions.TemplateNotFound: index.html.j2

[tyannalaq]

hi @hbcarlos , uh this might be a very dumb question but how do i check the versions?

[hbcarlos]

No, it is not! You can run pip list | grep voila.

(base) C:\Users\tyann>voila FYP0315.ipynb --template=gridstack And If I may give you a small tip, you should not use your base env.

[tyannalaq]

i just managed to check the voila version with pip list and it's 0.2.16, thanks for the tip! but how do i change the env and what should i change it to ?

[hbcarlos]

That's great! I recommend you to create a new environment and install voila-gridstack there. The best way would be by running the following commands.

# Create a new environment
conda create -n env_name -c conda-forge voila-gridstack
# Activate your environment
conda activate env_name

If you are using other libraries in your notebook like IPyWidgets, pandas, matplotlib, numpy, etc. You can add them to the create command as follows:

# Create a new environment
conda create -n env_name -c conda-forge voila-gridstack IPyWidgets pandas matplotlib numpy
# Activate your environment
conda activate env_name

or install them later as follows

# Create a new environment
conda create -n env_name -c conda-forge voila-gridstack
# Activate your environment
conda activate env_name
# install more packages
conda install -c conda-forge IPyWidgets pandas matplotlib numpy

hi ! i've created a new environment, activated and downloaded packages:

[trungleduc]

@tyxnna you need to install ipykernel in your new environment:

conda install ipykernel

[hbcarlos]

That's right, I forgot the kernel. Thanks, @trungleduc!

[tyannalaq]

thank you so much @hbcarlos and @trungleduc it's working now! for future reference, may i know WHY this problem occurred and how did changing the environment help?

also a little irrelevant to the topic but 1) is there a way to choose specific cells to be shown in voila? say if i don't want anything else to show except the plots? 2) can i readjust the plots to show the full plot instead of having to scroll like the attached photo?

[hbcarlos]

Hi @tyxnna! I'm happy to hear that everything works now.

The issue was that voila-gristack was not installed.

is there a way to choose specific cells to be shown in voila? say if i don't want anything else to show except the plots? can i readjust the plots to show the full plot instead of having to scroll like the attached photo?

Using Voila-Gridstack you can select which cells you want to show, and which order. To remove the scroll bar you need to resize the cell from the JupyterLab extension. There is a small screencast here about the voila-gridstack extension for JupyterLab that could be useful.

[tyannalaq]

i've managed to resize and rearrange the cells but i can't seem to be able to choose which cells to show and remove from the view. for example (see attached pic), is it possible to remove these dataframes from the view? currently, i can minimize them but not completely remove

[hbcarlos]

Hi @tyxnna. It looks like it could be a bug.

Each cell on the GridStack Editor should have a toolbar with a trash can to remove them. I can see the toolbar but it is empty. Could you run these commands in your environment and post the output? I need to know which versions are you using. pip list | grep voila and pip list | grep jupyter.

[jtpio]

FYI I transferred the issue to the voila-gridstack repo since the discussion is mostly around it.

[ukmusarra]

I am having similar problems with Voila gridstack and jupyter lab, in which the icons and the grid layout does not appear as options in toolbar and cannot be edited. Tried the new environment approach, same thing. running the commands above I get:

pip list | grep voila voila 0.4.3 voila-gridstack 0.3.1 voila_topbar 0.1.1

pip list | grep jupyter jupyter_client 8.5.0 jupyter_core 5.4.0 jupyter-events 0.8.0 jupyter-lsp 2.2.0 jupyter_server 2.9.1 jupyter_server_terminals 0.4.4 jupyterlab 4.0.7 jupyterlab-pygments 0.2.2 jupyterlab_server 2.25.0 jupyterlab-widgets 3.0.9

Can you help me to get gridstack editor to function properly in jupyter lab please ?

[trungleduc]

can you upgrade to voila 0.5.x?

[ukmusarra]

ok, just done that, thanks, but the following error appeared:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. voila-gridstack 0.3.1 requires voila<0.5.0,>=0.2.0, but you have voila 0.5.3 which is incompatible.

and nothing has changed from previous statement.

have updated both to newest versions, here's the labextension output.

jupyter labextension list

JupyterLab v4.0.7 /Library/Frameworks/Python.framework/Versions/3.12/share/jupyter/labextensions jupyterlab_pygments v0.2.2 enabled X (python, jupyterlab_pygments) @jupyter-notebook/lab-extension v7.0.6 enabled OK @voila-dashboards/jupyterlab-preview v2.2.0 enabled X (python, voila) @voila-dashboards/jupyterlab-gridstack v0.4.0-a0 enabled X (python, voila-gridstack) @jupyter-widgets/jupyterlab-manager v5.0.9 enabled OK (python, jupyterlab_widgets)

The following extensions are outdated: jupyterlab_pygments @voila-dashboards/jupyterlab-preview @voila-dashboards/jupyterlab-gridstack

Consider checking if an update is available for these packages.

but when doing the below, it returns old version...weird

pip list | grep voila
voila 0.4.3 voila-gridstack 0.4.0a0

pip list | grep jupyter
jupyter_client 8.5.0 jupyter_core 5.4.0 jupyter-events 0.8.0 jupyter-lsp 2.2.0 jupyter_server 2.9.1 jupyter_server_terminals 0.4.4 jupyterlab 4.0.7 jupyterlab-pygments 0.2.2 jupyterlab_server 2.25.0 jupyterlab-widgets 3.0.9

[ukmusarra]

in the meantime, how can I run the gridstack in edit mode please ? I can run the gridstack as template and passing the --VoilaConfiguration.resources="{'gridstack': {'show_handles': True}}" I can resize (but not delete), however, it does not save, returning to original every refresh. I have several notebooks already coded for voila/ipywidgets format (interactive etc.) and will be a pain right now (not talking about time) to switch for other option, such as panel or mercury. I need to be able to complete the dashboards please. your help is much appreciated

Can you create a new environment with the correct version number: voila 0.4, jupyterlab 3 and voila-gridstack 0.3.1 then try again?

it'll be easier to detect the issue if you can create a new issue and fill the template.

I have done the following steps: 1) downgraded python to 3.8.0 version 2) created the virtual environment 3) installed the required versions as suggested above

the issue is not resolved.

observations: 1) I can see the gridstack icon within jupyter lab, however, it neither resizes nor saves the layout when changed. 2) when launching gridstack from terminal it stacks automatically, with all widgets/markups 3) passing the option handles (from terminal) mentioned above, it works the same way as reported. It is not possible to delete any grid panel and once refreshed, it resets everything.

Please advise what to do. thanks

It works well for me with voila 0.4.3, jupyterlab 3.6.5 and voila-gridstack 0.3.1

Thanks for that. I installed the same versions and I was able to get the same behaviour, but still, I have questions:

1) As you can see the resizing is not working, which means they just stack the widgets on top of each other (and control the width when you insert them. How can I create the dashboard in a full gridstack layout (not half screen), and resize as I wish ? 2) I have a dynamic function, which means I use decorators, therefore, the size of the box needs to change as it goes. This behaviour causes the frame to become scrollable instead of expanding. How can I address this please ? is there a way to fix the widget size in grisdstack, or be flex ? 3) Lastly, when you install jupyterlab 3.6.5 it comes with jupyterlab-server 2.25.0 and jupyterlab-widgets 3.0.9. why did you downgrade them please ? Which version of ipywidgets are you using ? when installing pip install ipywidgets, it comes with version 8.1.1 which requires jupyterlab-widgets~=3.0.9. please clarify. thanks again for the support.
