Stop me if you'be heard this before, probably a duplicate --

https://hvplot.holoviz.org/releases.html says

0.8.3 Please note that hvPlot is not yet compatible with Bokeh 3.

and in fact

pip install hvplot  # 0.9.0
python -c 'import bokeh; print( bokeh.__version__ )'  # 3.1.1
python -c 'import hvplot'
    ModuleNotFoundError: No module named 'bokeh.models.arrow_heads'

OK, try again:

pip install hvplot 'bokeh<3.0'
    # uninstalled panel-1.0.3, installed bokeh-2.4.3 panel-0.14.4
python -c 'import hvplot'
    bokeh/__init__.py
    ... param/__init__.py:1339
    ValueError: ClassSelector parameter None value must be an instance of (function, tuple), not <fu

May I suggest

1. describe "How to install hvplot with pip" in the release notes
2. fix https://github.com/holoviz/hvplot/blob/main/setup.py

install_requires = [
    'bokeh >=1.0.0,<3.0'  # any more ?

My versions: python 3.10.0 macos 10.15.7 -- maybe old mac versionitis ? Thanks cheers -- denis

This sounds like you're getting a holoviews version that is still incompatible with bokeh 3. Could you try pip install holoviews==1.18.0?

Thanks @philippjfr, that works

Successfully installed bokeh-3.3.0 holoviews-1.18.0 panel-1.3.0 param-2.0.0

no idea why pip install hvplot didn't, see https://xkcd.com/1987
