Hi all, I have been using Julia for most of my course over the last 5 years. The students usually install VScode + Julia on their own machines and then the course mostly relies on notebooks. Habitually, things go smooth, despite the diversity of student computers (new-old machines, mac-linux-window…

Do you mean jupyter notebooks? and do you run them within vscode?

Yes, exactly. We run the jupyter notebooks within VScode. Yesterday, we managed to fix one Windows machine (Julia working in VScode using a simple script but not using Jupyter notebooks within VScode) by making a “clean restart”. I will write the steps explicitly, in case it can be helpful to anyon…

Do you think that jupyter is using the 1.11 kernel, while the simple script is using 1.10? (I mean on the devices that show the problem)

Unfortunately no, we did a “clean restart” this morning on both macs. This did not help. This time only 1.10 and release channel were installed and this did not help. Next, I will try using JupiterLab instead of VScode notebooks, which will require explicitly the installation of IJulia. I hope this …

Why don’t you skip installing the release channel? the vscode extension will complain but should work fine.

It was also failing before I installed the release channel. Since there was the warning, I thought it would anyway be good to get rid of it, and that it may help things to run.

I think you should install IJulia explicitly, then the jupyter notebook within vscode should be able to communicate with julia. (even if the julia extension of vscode is not installed)

We’ve tried it but it did not help either. Eventually one student installed JupyterLab and can now use Julia’s kernel in there, so it’s one success. Now there is still one issue with a mac, which appears too old (2017) to reliably support installation of JupyterLab (warning during homebrew install s…

Thanks! This explain why removing .vscode was not sufficient to erase all previous settings (e.g. last files opened). So far, it seems that students manage to install JupyterLab with Julia kernel - so at least they can follow the lectures! I will try again later to get everything running in VScode …
