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.

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.

@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.

@MarcSkovMadsen Are these the resources you mention? https://github.com/streamlit/streamlit/wiki/Community-Resources

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.

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.

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.

Hvplot control the color bar smaller color map units i want to specific the smaller units in color bar to 1 . currently it is in decimal form

@philippjfr
@MarcSkovMadsen I believe .show should return the server instance which you can call .stop() on.
@khannaum I'll try to get through some Discourse questions this evening.

Hi all, I've created a dev environment for panel based on its Developer Guide. I'd like to know what's the best way to update panel's dependencies? I've made a few conda update dry runs and what it suggested wasn't so nice, in particular it wanted to install panel (which is already installed in develop mode). I don't know exactly why, maybe because I have holoviews in my environment.

Hi! I found a typo in a Datashader example but I couldn't figure out how to contribute to fix it :) any contributor guidelines that I couldn't find?
Maxime Liquet
@maximlt
Hi @sam-hoffman, most of the content of the pyviz websites (including datashader) are built upon notebooks. If you browse the examples folder at https://github.com/holoviz/datashader, you'll see plenty of them. Find yours, open it and click on the Edit button (a little pencil). The raw content of the notebook should be displayed (don't worry if it's a little ugly) and you should now be able to edit it and submit your edit as a new commit. This is for me the simplest and fastest way to fix a simple type. If you need to run the code of the notebook, that's a completely different story ;)

Regarding file watching and automatic reload in the Awesome Panel Designer https://discourse.holoviz.org/t/awesome-panel-designer/643/3. Should I look to watchdog or the built in file watching in Tornado for the --dev server to enable this? I tried experiements with watchdog but could not get it working when running on Tornado. Watchdog starts a seperate thread dont know if that is a problem?

Is there a current best practices document (I recall there being mention of a forthcoming blogpost) about how to best use holoviews/panel/Voila/Datashader?
Philipp Rudiger
@philippjfr
Not yet, I'm currently working on ironing out the last issues and should be done by the end of the week, then I'll start with the blog post and then we need to release all the associated libraries.

Thank you Philipp, I will stay tuned to read through that then.

If you have time to test things I can ping you when they are ready.
Marc Skov Madsen
@MarcSkovMadsen
Nice about the best practices. I'm experimenting a lot with a model-services-component-view based architecture for the larger things I do. I can't really tell if its good or bad. There is a lot of code to write and its a bit difficult to work with beginners who dont understand the concept. But it really helps to break things down.

great - I will do my best to properly test.

There is a question (not from me) on stack overflow regarding Panel authentication. Maybe somebody with knowledge could take a look and provide a better answer than I can. See https://stackoverflow.com/questions/60156510/simple-authentication-using-python-panel-holoviz/61788878#61788878
I'm working on auth right now which is why I stumbled upon the question. I can get auth working with panel serve from command line. But not with python and then .show() or pn.serve() in the python file. Is that correctly understood?
Marc Skov Madsen
@MarcSkovMadsen
Another question regarding auth from a user on stackoverflow. I'm not capable of answering. But take a look if you have the time and knowledge. https://stackoverflow.com/questions/60169875/handling-user-authentication-in-flask-bokeh-panel-setup
