Holoviews: ImportError: cannot import name 'Dimensioned' from 'holoviews'

[leifulstrup]

I am trying the Gapminder example from here - https://github.com/pyviz-demos/gapminder

When executing the code segment from the example jupyter notebook cell:

pn.Column(gm.param,
pn.Row(gm.hvplot_view, gm.altair_view),
pn.Row(gm.mpl_view, gm.plotly_view))

I encounter this error:

ImportError: cannot import name 'Dimensioned' from 'holoviews'

in this code context:
/lib/python3.7/site-packages/panel/pane.py in applies(cls, obj)
185 if 'holoviews' not in sys.modules:
186 return False
--> 187 from holoviews import Dimensioned
188 return isinstance(obj, Dimensioned)
189

My environment:
OSX 10.14.5

The hvplot version you are getting is quite outdated, you'd want hvplot 0.4.0. Same is true of panel which is now on version 0.6.0. Even holoviews seems to be outdated as the latest version is 1.12.3.

[leifulstrup]

Philipp, thank you. I followed the conda install instructions and it kept loading these earlier versions. I'll figure out how to get everything updated. Appreciate the rapid response. Looking forward to using your great tools.

[jbednar]

One thing you can do if you're having trouble is to go to status.pyviz.org to see what the latest versions of things are, and then explicitly specify them in your conda install command. E.g. conda install panel=0.6 hvplot=0.4 holoviews=1.12.3.

[leifulstrup]

James, thank you. I'll try that now.

[philippjfr]

Wonder why you're getting these old versions by default though. Seems very strange.

[leifulstrup]

This solved it for me:

conda install -c conda-forge panel=0.6 hvplot=0.4 holoviews=1.12.3 altair=3.1.0 plotly=3.10.0

[leifulstrup]

James and Philipp, thank you both for the fast response and help. I recently set up Anaconda from scratch and kept trying to update it but could not get the more recent versions of the packages. I'm sure it is "operator error" on my side. I appreciate the help. It's working great in my Jupyter notebook. Looking forward to trying it with a real application I'm working on.
