It works for me @rh1. Try upgrading HoloViews as well

panel=1.3.1
holoviews=1.18.1
hvplot=0.9.0
param=2.0.1

Please also note that hvplot.interactive has been generalized to param.rx with the release of Param 2.0.

The example would now look like

import pandas as pd
import panel as pn
import param

pn.extension(design="material")

df = pd.read_csv('https://datasets.holoviz.org/penguins/v1/penguins.csv')

species_widget = pn.widgets.Select(name="species", options=["Adelie", "Gentoo", "Chinstrap"])
year_widget = pn.widgets.IntSlider(name="year", start=2007, end=2009)

idf = param.rx(df)
idf = idf[(idf["species"] == species_widget) & (idf["year"] >= year_widget)]

idf.head()

Thanks @Marc , It works when update holoviews to the latest version. thanks also for example using param, since no documentation in holoviz website regarding new param.

thanks
