jupyter-sankey-widget javascript error

[andrewSharo]

Hi Rick,

I previously used floweaver without issues, but I recently upgraded to Jupyter lab and lost all my old conda environments. I created a new conda environment for floweaver, followed your conda install directions (the jupyter nbextensions appeared to be created correctly), and I ran the following cell:

from ipysankeywidget import SankeyWidget
SankeyWidget(links=df.to_dict('records'))

and received the following javascript error in Jupyter lab:

Failed to load model class 'SankeyModel' from module 'jupyter-sankey-widget'
Error: No version of module jupyter-sankey-widget is registered

I thought maybe this was a jupyter lab issue, so I tried a jupyter notebook. Running the same cell, I received this javascript error:

Model class 'SankeyModel' from module 'jupyter-sankey-widget' is loaded but can not be instantiated
TypeError: o._deserialize_state is not a function
at u._make_model (https://rage.berkeley.edu:9994/nbextensions/jupyter-js-widgets/extension.js?v=20221008205050:2:747339)

Which seems to be making some progress. Have you seen this before? I can try on another machine, but wanted to check with you in case this was familiar or you had any ideas.

Best,
Andrew

Hi Andrew, I think it is the same issue here: ricklupton/ipysankeywidget#53 (comment) Some updates for jupyter notebook / jupyter lab are overdue! But hopefully in the meantime downgrading the packages mentioned in that issue will get it working again.

Hi Rick,

Thanks for linking to that issue. I can confirm that downgrading the packages solved the issue. I also found that it only worked when I was running a native jupyter notebook environment. The supposed jupyter notebook environment available through jupyter lab does not work. I'm just leaving that as a note for others who may have the same issue.

Best,
Andrew
