Most easy things to improve 1) More info about support options 2) Deployment guides

@MarcSkovMadsen
Most difficult things to improve 1) The api - gets some feedback on being hard to learn.

This issue holoviz/holoviews#4875 is being seen my me, but also a colleague at my firm, plus the other folks who posted about the issue. We can't render anything with holoviews using bokeh right now. Hope you can look into it.

@jbednar
Scary! @philippjfr ?

The main problem is that I cannot reproduce under any conditions I've tried.
Irv Lustig
@Dr-Irv

@philippjfr I can reproduce as follows:

conda create -n hvtest0402 python=3.8
conda activate hvtest0402
conda install pandas holoviews
conda install jupyter
jupyter-notebook

Then I ran the file https://holoviews.org/user_guide/Applying_Customizations.html but changing the hv.extension call to only use bokeh and cannot get any visualization.

This is on Windows.

Could recreate the problem with a clean install in WIndows. It seems to be related to packages in thedefaults channel if I run conda update --all -c pyviz -c conda-forge -y in the environment I could get it up and running. Though it creates another problem where I could not start a jupyter notebook, so I used jupyter lab instead of.

Defaults doesn't yet have latest panel so that won't work.

Hi, attemting to run the following example https://geoviews.org/user_guide/Resampling_Grids.html will trwo an errror: AttributeError: 'DataArray' object has no attribute '_file_obj'
James A. Bednar
@jbednar
That sounds like a bug report! Please file it at the geoviews github repository.
Thanks!
epifanio
@epifanio
yes, I was wondering of where to report - I will fill an issue with the version of sw I am using
James A. Bednar
@jbednar
Perfect.
Philipp Rudiger
@philippjfr
@jbednar You should have recognized that as the datashader bug that we fixed recently :)
So @epifanio just update to Datashader 0.11.1
Not even we, you fixed it 😉
epifanio
@epifanio
@philippjfr before filling the issue, I was attemting a rebuild making sure the packages are all installed with a single tool (mamba in my case) and double check I do not have any of the pyviz libraries installed via pip - I will wait the end of docker build and test it.
@philippjfr you meant datashader v0.12.1 , right?
Philipp Rudiger
@philippjfr
I did sorry
epifanio
@epifanio

no prob!
I checked the latest tagged releases to make sure the problem was on my side, so I ended up runing (on the running server):

 pip install geoviews==1.9.1
 pip install holoviews==1.14.2
 pip install param==1.10.0
 pip install datashader==0.12.1

and I saw the bug was no longer there .. bu this also messed-up my jupyter widgets .. hence a rebuild
Now I want to check if mamba is doing the right things otherwise I will try pip.

James A. Bednar
@jbednar
I don't keep knowledge of fixed bugs in my memory; always onwards and upwards! :-)
But I have noticed that I really had to force conda to update datashader to anything past 0.10 even specifying the pyviz channel, which may be why people are still running into this.
epifanio
@epifanio
I confirm that, mamba installed the older version - manually upgrading with pip fixes the problem

is using opts.defaults to set default for the whole notebook supposed to work for hvplot? If yes, I'll submit a new issue.
Michael Aye
@michaelaye
is this sentence in the hvplot docs potentially incomplete?
x_sampling/y_sampling (default=None):
    Declares a minimum sampling density beyond.
James A. Bednar
@jbednar

is using opts.defaults to set default for the whole notebook supposed to work for hvplot? If yes, I'll submit a new issue.

My guess is that opts.defaults would work only for options not processed as hvplot command-line arguments, except maybe for some that are just passed through. Basically, HoloViews's option system lets you use opts.defaults to set global defaults, but then those defaults get overridden by any values specified explicitly. Due to how hvPlot works, I would assume that it sets various options explicitly even when the user doesn't provide values, in part because hvPlot defaults need to match Pandas defaults, not HoloViews defaults. So no, I don't think hvPlot not being responsive to changes in opts.defaults counts as a bug.

And yes, that sentence is incomplete. The corresponding HoloViews docstring for x_sampling is "Specifies the smallest allowed sampling interval along the x axis.".
A PR to fix that sentence would be welcome!

I will be having a question on how a package can serve dynamically generated assets (js files transpiled by Transcrypt) without the need for the user to add a flag to serve folders.
and so that it works in the notebook as well.

@jbednar
Pretty cool! Maybe the logo could be more like this?

And I can generate a version of the Sketch bit with the same kerning as Panel, though I always have to remember how I do that.

@jbednar
Ah, I use Inkscape and tighten the inter-letter spacing:

Steve would like to write a blog post about HoloViz but has trouble providing a working example in colab. If any body could help it would be great https://discourse.holoviz.org/t/how-to-make-the-dashboards-example-work-on-google-colabs/2109/2
