Just a heads, it turns out the IJulia kernel was not actually running in my Julia notebook opened in VScode. The results of `isdefined(Main, :IJulia)` and `Main.IJulia.inited` were both false. I’m not exactly sure what backend was running the notebook, I’m assuming still IJulia since I needed it downloaded globally, but something must have still been messed up.

As an end user, this was an issue because I wanted access to specific IJulia commands, such as `IJulia.clear_output()`. In order to get VScode to start IJulia and realize it was running in my notebooks, I had to make a symlink from the (at the time non-existence) path to where Julia itself normally installs itself when using the exe/dmg, to where I had actually installed it with Homebrew. Not sure why, but IJulia automatically assumes to check for the exe/dmg location for the julia executable, and that, apparently, was causing me some issues.

Hope this helps someone out there!

Hi, it happens quite regularly in the lectures where we use the combination of VScode notebooks with Julia. I’ve not managed to identify a robust solution so far. For some students it ends up woking after restarting VScode a couple of times, for others it works after an OS restart, for other it works after a clean uninstallation/reinstallation (involving deletion of the .julia/ folder or even the [.vscode/](https://discourse.julialang.org/t/problem-with-installing-julia-notebooks-for-a-course/121540/10) folder). Now, a pragmatic solution is to switch to using google colab, whenever this problem is met…
