by the way, i love the new dark theme
the dependencies are only zio and java's stdlib right?
Good afternoon,
Great work so far on the notebook, the Scala support is fantastic.
I have a question regarding Vega which I have seen has been asked before but I can't find an answer of as yet. Is there an example of how to use a Vega Spec? Is there an example of how to use the plot feature? I can reach the "plot" UI with a Scala Spark dataframe however it doesn't allow me to select anything for the x axis, everything shows as radio buttons in the y axis section only
What is the incantation that allows me to reference data from Scala/Python cells in the Vega spec?
Is this feature available?

I managed to get the plot working by ensuring I had a "string" type in my Dataframe. However I couldn't do a simple x/y scatterplot for a Dataframe of (Double,Double)
I can see the plot rendered in the plot UI however if I click "source" and copy/paste the Vega spec back into a Vega cell it doesn't render when in the notebook. It doesn't error and there is nothing in the console

oh, looks like scala-native does have an NIO implementation. Dang, that's a lot of work, kudos to them :grinning:
For me after switching reading csv-es does not work a all :(
getting this error when adding a dependency: https://mvnrepository.com/artifact/diff_match_patch/diff_match_patch/current
Illegal character in scheme name at index 4: diff_match_patch:diff_match_patch:currentis the dependency parser too strict? is there a workaround?

Hello @all,
i want to know is there any documentation to setup polynote in Intellij .
i tired to run Polynote from intellij and worked pretty well , fronted is working but when i start kernel i got an exception
| java.io.IOException: Cannot run program "spark-submit": error=2, No such file or directory
please someone help me how can i resolve this

apologies, I hope to have actual docs about this kind of stuff in the not-too-distant future
Just quoting this from your page - "Polynote is currently only tested on Linux and MacOS, using the Chrome browser as a client. We hope to be testing other platforms and browsers soon. Feel free to try it on your platform, and be sure to let us know about any issues you encounter by filing a bug report." When should Windows guys expect support for our platform? Don't get us sidelined. This looks more promising than what we should miss, you know?
In case you haven't got it running yet, I created a script to run polynote on windows (using docker). It run's the currently latest polynote version 0.3.11 but I'll soon update it to automatically pull the newest version (notebooks are persisted in a mounted folder). Feel free to check it out.

Hi @moritzbaumotte thanks for your interest in Polynote! I’m curious, what prevents users from using the official polynote docker images (https://hub.docker.com/r/polynote/polynote) on Windows?
By the way, it does seem like a decent number of people have been successful running Polynote on Windows with Windows System for Linux: polynote/polynote#671
It looks like our documentation was out of date on the website, because it was supposed to say that. I’ll fix the doc update job and hopefully reduce confusion here.
As for the official docker image, you can run it properly on Windows, Polynote starts correctly inside the container but you can't access it from the Windows host (you'll get some connection refused or connection timeout error). To access it from Windows Polynote would need to socket bind to 0.0.0.0 inside the container rather than 127.0.0.1 (which it is per default I belief). That's what this tiny config.yml is for in my repository.
That’s expected with Docker. Here’s our official docker documentation: https://github.com/polynote/polynote/tree/master/docker#official-docker-images
For security reasons the official Docker distribution needs you to provide your own configuration. This is by design; please see https://github.com/polynote/polynote/issues/666#issuecomment-555212474 for more about our rationale.
Okay, then I can't explain it. I basically took an older approach on Dockerizing Polynote for Windows and completed it fixing any bug I could find until it worked.
Btw, I've updated my repo that it automatically uses the newest Polynote version - not a pretty solution but good enough to make it run. ;)

I think the base image would have to be based on something like nvidia/cuda:9.0-base :(
Here’s the Dockerfile Polynote uses. You should be able to change the base image to whatever you like, all you'd need to do is make sure to install java
(now, getting the python running inside of Polynote to properly interface with cuda… no idea if that would work. )
the nvidia GPU is not on my main dev machine, so this is quite cumbersome to try... maybe I'll check that during the weekend :sweat_smile:
@raproth This is due to a recent change in the new release: polynote/polynote#951 Didn’t realize it wouldn’t work in 3.6 but we’re mainly targeting 3.7. Any particular reason you’re using 3.6?
