Does anyone have a few minutes to have a look at matplotlib backend issues?

@MarcSkovMadsen

I've been in contact with Michael from Talk Python to Me and suggest he talk to @philippjfr about Panel and HoloViz. Here is his reply.

Hi Marc,

This is really interesting. I just started hearing about Holoviz. Looks like a great project. I'll reach out and see if I can put something together. :) Love the awesome-panel project too.

Cheers,
Michael

@philippjfr , I"m getting lots of WARNING:param.GeoOverlayPlot03010: title_format is deprecated. Please use title instead when using hvplot/geoviews/holoviews/panel. But I'm not specifying title_format.
Philipp Rudiger
@philippjfr
Working on getting a new hvPlot release out right now.
Rich Signell
@rsignell-usgs
okay

@poplarShift
For writing tests in param, do I just insert (almost) identical code into both API0 and API1? What is the idea behind that?
Philipp Rudiger
@philippjfr
API0 will be dropped in param 2.0, I don't think there's any need to add new tests to API0
Achim Randelhoff
@poplarShift
thanks!

@poplarShift
Has anybody here collaborated with the cartopy people and knows how they roll? I submitted a PR SciTools/cartopy#1500 to address GeoViews issue holoviz/geoviews#450 (and one of their own existing issues) a month ago but haven't gotten a single line of feedback despite pinging them on their gitter. Submitting the PR to GeoViews instead seems hacky. Any ideas?
Philipp Rudiger
@philippjfr
I'll try to ping somewhere there. I've worked with some of them in the past but many of the people who initially wrote it have moved on and I don't know the current maintainers too well.
Achim Randelhoff
@poplarShift
great, thanks!
Philipp Rudiger
@philippjfr
It's very unfortunate because cartopy is a great package, but there doesn't seem to be anyone who has sufficient time to actively maintain it. Basically certain functionality is totally broken right now with latest proj/pyproj but there has been zero progress for months on the release that would fix it.
Achim Randelhoff
@poplarShift
That is indeed sad. I remember when I initially started using cartopy it was usually described as the replacement for basemap
Philipp Rudiger
@philippjfr
That's still the case.
Achim Randelhoff
@poplarShift
Of course no maintenance at all is way worse. It did convey a sense of long-term commitment though
Philipp Rudiger
@philippjfr
I mean technically it's still maintained it just seems like there's no one who is actually funded to do so.

Hi all , I am Sandhya and I use the datashader package quite a bit and it is amazing. I have a few questions on creating a raster using datashader. Is there a way I can create a GeoTiff with datashader, with CRS and bounds properties?
Philipp Rudiger
@philippjfr
@raghavansandhya Thanks for your question, would you mind posting it to the Discourse (https://discourse.holoviz.org/) so the answer can be preserved for other users?
Sandhya Raghavan
@raghavansandhya
Sure

If you are interested in Panel and the "alternative" python frameworks like Streamlit, Voila and Dash checkout this awesome video https://www.youtube.com/watch?v=K7eDJT7djro.

Ned does a really good job at explaining the why and also how the frameworks differ.

Maxime Liquet
@maximlt
Hey @MarcSkovMadsen thx for sharing that video, I watched it and really appreciated that he tried hard to cover all the existing tools. I'm just a little bit frustrated by his video (and others too) as he didn't explain how to deploy the app you can build with those tools. It's not often covered unfortunately, this really is to me a missed point as those tools are of no use if at the end of the day you don't know how to deploy your little app :D
Marc Skov Madsen
@MarcSkovMadsen
Yes @maximlt . Deployment is the big pain. That is why Streamlit tries to build their business model on easy deployment and similar stuff and Enterprise would want. But there are many, many guides out there in the Streamlit community now. And the Panel and Bokeh documentation also explains how to do it to some extent. In my experience there is just always something that it is a bit special or goes wrong.
If someone can explain if instantiate of param.ClassSelector works as expected in the code example provided here holoviz/param#406 or I've identified a bug I would really appreciate it. And if someone could explain the why and what of instantiate it would really be appreciated. I've been trying to understand it for a long time without luck. I especially need to understand the Why otherwise I will never be able to remember how it works. Thanks in advance.
Maxime Liquet
@maximlt
@MarcSkovMadsen it is indeed a big pain ^^ Even more if your journey just started from playing around with data in a notebook and suddenly you're asking yourself how the hell you're gonna deploy your little app to the web without any knowledge at all. The kind of guidance/docs required here should be thorough ! Do you think the guides available in the Streamlit community could be adapted (or just copy/pasted) for panel? If yes it could be added here: https://panel.holoviz.org/user_guide/Server_Deployment.html
Philipp Rudiger
@philippjfr
+1 we were planning on adding very detailed deployment guides but I never quite found the time.
Marc Skov Madsen
@MarcSkovMadsen
I think the streamlit guides could be refactored to Panel pretty easily.
Maxime Liquet
@maximlt
@MarcSkovMadsen Are these the resources you mention? https://github.com/streamlit/streamlit/wiki/Community-Resources
Rich Signell
@rsignell-usgs
an hvplot command that used to work now requires a load() to work. https://nbviewer.jupyter.org/gist/rsignell-usgs/36aa0b894c47584412b2a23ccb84f074
Is this a known issue? If not I can raise it on github or discourse
Philipp Rudiger
@philippjfr
Ryan already raised that issue and it has been fixed. Just waiting on a new datashader release.
which is overdue and just waiting on Jim to check a few last things.
Rich Signell
@rsignell-usgs
:thumbsup:
Philipp Rudiger
@philippjfr
If you could try it with datashader 0.11.0a3 from the pyviz/label/dev channel that would be helpful though.
Rich Signell
@rsignell-usgs
I'll try that after my demo today. :-)
Marc Skov Madsen
@MarcSkovMadsen
but there are many newer. If you take a look at What Streamlit have like or reshared on Twitter and LinkedIn you Will find a lot.
Marc Skov Madsen
@MarcSkovMadsen
Is there a way to programmatically (i.e. from code) stop the Panel server? I started it with my_panel.show() and would like to click a button in the app to stop the server.
