Hi everyone, I've got problems updating the Kotlin Jupyter Kernel. I followed the procedure on its website, i.e.:
``pip install kotlin-jupyter-kernel --upgrade``.

It correctly downloaded and installed the 0.11.0.208 version.

However, everytime I launch jupyter notebook and connect to it with the Kotlin Notebook IDEA plugin I get told that the kernel version (0.1.0-170) is incompatible the kotlin-dataframe version.

If I scroll at the top of the log, I can see that indeed it tries to use the 0.11.0-170 version:

Kernel args: /tmp/kotlin-kernel-config-kernelProcessConnection15069667844898789499.json, -home=/tmp/kernelProcess16547460509079481210, -cp=/tmp/kernelProcess16547460509079481210/lib/kotlin-jupyter-api-0.11.0-170.jar:/tmp...

Deleting the /tmp/kernelProcess* directories changes nothing.

Note that it seems to work correctly if I open the notebook directly in the web version of Jupyter.

Now kernel is embedded into plugin so there is no way do update it with pip in plugin. The only way is to update a plugin itself. If after plugin updating version is the same, please use the previous version of dataframe for a while

I see. Thanks a lot for you quick answer!

Is there a repository for the dev version of the plugin? I cannot find any newer versions than 223.8214.52 (for IDEA 2022.3.1) on the plugin homepage (cf. https://plugins.jetbrains.com/plugin/16340-kotlin-notebook/versions). It seems there are only nightly builds for 2021 versions of IDEA.

Also, I am not specifying anywhere any version for Kotlin Dataframe. It seems to be selected automatically by the Kotlin Jupyter kernel.

%useLatestDescriptors
%use dataframe, lets-plot

We have Nightly builds, but they are not publicly available. I hope that update for kernel will be present in the next 223.* build

It's actually taken from here:
https://github.com/Kotlin/kotlin-jupyter-libraries/blob/master/dataframe.json

You may try previous stable version of dataframe (released in the end of July, 2022)

%use dataframe(0.8.1)
