Doesn't work - no effect

[mcaay]

I have the newest version of vs code, jupyter extension (although not Pre-Release) and I just installed your plugin. VS Code still asks me every time which kernel to pick. I used settings.json to hide all the other kernels. I pressed cmd+shift+P to use command Python: Select interpreter and selected the desired one. Still every time I open a jupyter notebook and want to run the code it prompts me to select kernel.

Did I still not do something that is necessary?

[DonJayamanne]

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to verbose
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel. You can get to the Jupyter Ouputput Panel by using the command Jupyter: Show Output

Hey, below is the jupyter output. What I did:

1. opened an .ipynb file that uses some API
2. tried to run the first cell with Shift + Enter
3. the select kernel popup appeared, but I didn't click anything

I also have this issue with the extension, though it does seem to work on occasion: If I select the appropriate interpreter for python and then create a new notebook it works, but if I then close down the workspace and start it up again the notebook loses the kernel and goes to the default one instead, with no means of switching back to the one I want.

[karlglazebrook]

I am finding this too, it seems to work inconsistently. Note I am just opening .ipynb files from the MacOS finder, not doing anything with 'workspaces'

[DonJayamanne]

I'm sorry for not getting back to you on this,

Please can you try the following

• Download the below file
• Extract this file
• Open VS Code
• Select the command Extensions: Install from VSIX
• Select the extracted vsix file
• When prompted, please reload VS Code,
• Test again
• If this still does not work, then select the command Output: Show Output Channel...
• Select Default Python Kernel
• Copy all of the output and paste it into this issue.

Noting this particular notebook comes up with 'Select kernel' so it has no default.

Some kind of cacheing issue from testing? I created a fresh notebook file and now the extension seems to work as expected.

[mjbaldwin]

This extension is also not working for me.

I have a notebook that I repeatedly duplicate and use the new version, and every time I open the new one, no kernel is selected.

My default Python interpreter is always correctly selected.
