Using reticulate in VSCode when dynamically executing quarto document

[psl-schaefer]

Bug description

I have simple Quarto document with one R and one Python chunk. I want to access R variables in the python chunk via reticulate (reticulate::repl_python()) which works fine when I work with the document in RStudio.

---
title: "Example"
format: html
engine: knitr
---

# r chunk
library(reticulate)
data(cars)

# python chunk
car_df=r.cars
car_df

However, when I am using VSCode it doesn't work anymore. When I execute the python chunk, a Python REPL is started that has nothing to do with the R Session. Thus, I get a NameError in the python chunk because name 'r' is not defined.

Am I using the wrong settings in VSCode? Why isn't the Python REPL started via reticulate::repl_python() as it is in RStudio? Funnily, if I knit the Quarto document in VSCode everything is working fine. It might be important that I am working over an SSH connection in VSCode.

I know that I could simply type in the R console reticulate::repl_python(), but it would be much more convenient if VSCode would "automatically" use the correct repl.

Version Info

I checked the source code of quarto-vscode. There is the difference between "Run (Python) Cell" and "Run (R) Cell": 172-194 lines

Maybe the reason for that python chunk is designed to be run in Jupyter Interactive by default is to enable python(jupyter) users get started easily. I think it's the right choice.

it would be much more convenient if VSCode would "automatically" use the correct repl.

But I also fully agree with your proposal: R users need a more convenient workflow in VScode to use the wonderful bridge(reticulate) between R and Python. Maybe give users a choice to change the python chunk run command to reticulate::repl_python() in quarto-vscode extention will be a beautiful thing, just like RStudio does ✨.

It might be important that I am working over an SSH connection in VSCode.

So I don't think this is an influencing factor 😀.

Hope this feature will be developed!

Hi folks, we hear you and appreciate your involvement. But a +1 comment on a thread just pollutes our notifications and means we have less time to fix bugs and implement features :).

Apologies, but it's unclear to me how to resolve this issue in its current state. In VS Code,I tried running reticulate::repl() in an R chunk and then running a python chunk, but still get the error that OP stated. Thanks!
