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”.

Do a clean restart of VS Code
Run the current script in interactive terminal:
The ipykernel message will appear.
The status says “Starting jupter server” indefinitely
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.

see my SO for details: https://stackoverflow.com/questions/59867847/how-does-one-connect-a-jupyter-kernel-to-vs-code-if-one-does-not-connect-automat

Copy pasted from my SO question :

I want to be able to have a working jupyter notebook working for VS code out of the box, with minimal work on my side.

I tried opening a jupyter notebook. I immediately found the interpreter and used my conda env with the command pellet (command + shift + P then in the drop down menu found my conda env). This seems to make the terminal work since which python points to the right place:

(automl-meta-learning) brandomiranda~/automl-meta-learning ❯ which python
/Users/brandomiranda/miniconda3/envs/automl-meta-learning/bin/python

also running python scripts from VS Code seems to be working fine too, see output:

(automl-meta-learning) brandomiranda~/automl-meta-learning ❯ /Users/brandomiranda/miniconda3/envs/automl-meta-learning/bin/python /Users/brandomiranda/automl-meta-learning/python_playground.py

x = 1
my_str = this is a string
y = 2

but when I try the jupyter notebook it doesn’t work.

Most noticeably my VS code does not have a kernel connected, look at the screenshot:

I tried clicking on a couple of arrows as suggested on reddit (vs_code_jupyter_server_no_kernel_python_not):

When I try running things in my jupyter notebook I get the following error:

Error: Activating Python 3.7.6 64-bit ('base': conda) to run Jupyter failed with Error: StdErr from ShellExec, /Users/brandomiranda/.bashrc: line 31: jump-module.bash: No such file or directory

  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.


.

which is strange. My shell is not even bash so I don’t know why that message is being shown to me (maybe VS Code doesn’t know Mac OS Catalina uses zsh? not sure how to fix that for VS Code). Regardless, I proceeded to do what I think the error message is suggesting. So I did the following:

I ran conda init and then went down to the terminal inside vs code and restarted the shell by running zsh but the jupyter kernel still doesn’t work on my notebook in vs code. Not sure what’s wrong.

In addition, I did what the error message suggested:

No action taken.

but it seems it made no difference.

Any idea how to fix this?

See photo, ipykernel is installed

$ conda list | grep ipykernel
ipykernel          5.1.2

When you click update it spins. I could ask the user to try that again.

We have changed the way we start a kernel. We now register the current interpreter as a kernel I noticed this and was the reason I decided to submit the issue.

Our conda environment is bepoke in these ways:

No access to outside conda channels
The base environment is C:\ProgramData\CustomConda
PYTHONPATH, and PATH are left untouched by our conda setup

Because of these customizations I thought we might’ve found an edgecase of the new kernel loading mechanism. The thing that really bothered me is that after some time had passed, with no updates to VSCode( I checked), or the python extension, began to work for the user I was working with. It also doesn’t happen on all on my machine.

There were definitely tracebacks in the developer console…but I failed to copy them…

Is that the recommended workflow to avoid IPyKernel detection issues?

That’s the recommended workflow if anything goes wrong with Conda. If you search ‘conda’ in the python extension issues there’s lots that can go wrong with conda activation. It works out better if you activate outside of VS code and just use that.

Thanks and sorry for the ambiguity. Yes, my issue was IPyKernel not being detected but launching vscode from an activated virtual environment seems to be doing the trick. Is that the recommended workflow to avoid IPyKernel detection issues?

Why did I have to go through this if conda was working for my zsh and I am not using bash anymore

No, this isn’t a VS Code issue. Basically conda wasn’t working for you in bash and thats outside of VS Code (i.e. we dont control that behavior).

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

Agree, however user environments are beyond the control of the extension. Hence the request to ensure the shells are configured correctly.

I totally agree, you can’t control the user’s environments. However, I am not using bash at all, so I don’t understand why my .bashrc file mattered. I guess that’s the point I was trying to make. I was using zsh. I’m pointing it out just in case it help you guys fix stuff 😃

Thanks so much for the help! 😃

@DonJayamanne @rchiodo

can you try Don’s fix here?

I can confirm that this fixes the issue.

Notifys that ipykernel is not installed

Thanks for reporting this issue. We have changed the way we start a kernel. We now register the current interpreter as a kernel. To do this we need ipykernel installed in the current interpreter. Hence you’ll need to select Yes to install ipykernel.

If you do not wish to to so, you could select another interpreter or another kernel.

Closing this issue as this is by design.

Note: The error you are getting about falling back from daemon seems to be cased by some missing file in your environment.

Please could you select Yes to installing a kernel and let us know how it goes.
