I'm trying to use panel with jupyter in VS Code but I get this error.
Here is everything that I imported to my code:
- pandas
- warnings
- numpy
- panel
- panel.extension('tabulator')
- hvplot.pandas
Current bokeh version is 3.1.1. I've tried with bokeh 2.4.0 and 2.4.3 but it just got worse.
Code in Jupyter:
data_slider = pn.widgets.DateRangeSlider(
name='Periodo',
start=df_base['DATA'].min(),
end=df_base['DATA'].max(),
value=(df_base['DATA'].min(), df_base['DATA'].max()),
step=2
)
data_slider
Error:

I had the same issue. What worked for me was reinstalling the following packages with these specific versions:
pip install panel==0.14.4, bokeh==2.4.3, jupyter-bokeh==2.0.4Hope this helps.
