Working with Streaming Data example cannot import 'DataStream' from 'holoviews.streams'

Hi all,
Complete newb to Holoviews so apologies if this is a dumb question.
I am looking to demo our streaming API with a bunch of different dataviz frameworks - ideally including Holoviz.
I found the following example - but when I try to run in Jlabs I get the following error:
Working with Streaming Data

cannot import name ‘DataStream’ from ‘holoviews.streams’

Any ideas how I can get the example working?
Thanks

Thanks for your post. Before diving any deeper could you tell us which version of HoloViews you have?

Sorry for the late reply - your message was in my junk folder.
I am using v 1.13.2

I ran the recommended install command from https://holoviews.org/install.html before attempting to use the example: conda install -c pyviz holoviews bokeh

The full error output when I try to run the example is:

ImportError Traceback (most recent call last)

3 import holoviews as hv

----> 5 from holoviews.streams import DataStream, DataFrameStream

7 import streamz
ImportError: cannot import name ‘DataStream’ from ‘holoviews.streams’ (C:\Users\umern\anaconda3\lib\site-packages\holoviews\streams.py)

Oh right, I should delete my notebook on anaconda.org, it was an early prototype. The real docs can be found on the HoloViews.org website: http://holoviews.org/user_guide/Streaming_Data.html

Thanks for replying. I have been pulled in on a real issue so this has taken a back seat.
I will the new version when I get a chance.
Many thanks.
