Trying to set up Polyglot notebook to work with Python and R

Question

I recently installed the Polyglot notebook extension for VS Code, and I am trying to set it up to work with Python and R. According to the developer's tutorial, it should be a simple matter of running the following lines in a notebook cell (i am not using Anaconda, and R is already configured for Jupyter notebooks):

#!connect jupyter --kernel-name pythonkernel --kernel-spec python3
#!connect jupyter --kernel-name Rkernel --kernel-spec ir

Executing a cell run with either of these commands will result in the cell timer running indefinitely without any errors. However, nothing happens.

When posting here, I tried retrieving the version using #!about as suggested in the issue template. Like the above commands, the cell timer runs like the cell is being executed but nothing is happening.

Seemingly, Polyglot notebook is not set up correctly, so I am wondering what I can do to get it to work?

Edit:

Anyway, I checked the Polyglot notebook: diagnostics console output, and it keeps reiterating the following message indefinitely:

Process 'dotnet' with PID 2588758 exited with code 150 and signal null
Started process 2588770: dotnet tool run dotnet-interactive -- notebook-parser
process 2588770 stderr: You must install or update .NET to run this application.

To install missing framework, download:
https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=7.0.0&arch=x64&rid=arch-x64

According to the linked guide above, it seems this error is caused by the required framework either being missing or not installed correctly. However, querying the package manager, the necessary packages seems to be installed:

Answer 1

It turns out the issue is with a missing package when I installed .NET from the Arch repo.

Turns out the runtime is shipped as a separate package in Arch. Installing aspnet-runtime resolved the issue.
