Also it appears to be intermittent…at lease on one occasion today the user reported and showed me that it did “Work” and the ipython kernel was started. I couldn’t tell whether it was daemon or fallback.

Let me know if you need any more details.

Ok I took control of the users computer and did some more exploring. I can now reproduce the “spinning forever” and the action which causes it to be “magically fixed”.

1. Do a clean restart of VS Code
2. Run the current script in interactive terminal:
3. The ipykernel message will appear.
4. The status says “Starting jupter server” indefinitely
5. and the Python Interactive window looks like this with the loading animation indefinitely:

Here’s the clue and source of intermittent behaviour: Everything gets unblocked when I click the x on the notification message which misidentified that ipykernel was not installed. If I had done step 2 multiple times they had been queued and the script will run multiple times.

@DonJayamanne seems that after I removed the conda command from my .bashrc it started working (I actually tried that right away). Weird, I am not using bash as a shell anymore (in mac os Catalina) so I don’t understand why that is affecting VS code (in fact, I don’t understand why my .bashrc file is even being ran).

Somehow removing all errors makes the jupyter notebook work, but I don’t think this is the intended way to have this work for the user, right? Why did I have to go through this if conda was working for my zsh and I am not using bash anymore. Is this a bug with VS code?

From a user’s perspective I expected it to work out of the box but it didn’t…is what Im trying to say.
