Jupyter: Select a Kernel command missing in Python Interactive context

[mparq]

Created out of discussion from #3724

Environment data

• VS Code version: 1.52.1
• Jupyter Extension version (available under the Extensions sidebar): 2020.12.414227025
• Python Extension version (available under the Extensions sidebar): 2021.1.502429796
• OS (Windows | Mac | Linux distro) and version: Mac 10.15.7 (Catalina)
• Python and/or Anaconda version: 3.8
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Jupyter server running: Remote (via local Docker)

Expected behaviour

In Python interactive window, I should be able to select a kernel via Jupyter: Select a Kernel command.

Actual behaviour

Command Palette does not show Jupyter: Select a Kernel in Python interactive context

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Open up a .py file after connecting a remote notebook server to Jupyter extension and run cell. Python interactive window opens
2. Notice that command palette willl not contain Jupyter: Select a Kernel command. However, top right of interactive window will show UI for selecting different kernel on remote notebook server.
3. Export .py file to .ipynb and open in new window. Notice that command palette for notebook context does have Jupyter: Select a Kernel as an available command.

Thanks for filing @mparq. I can confirm there is no command (even if not using remote). I'll bring it up in our next meeting.

I have the same issue for .ipynb files, with the additional bug that if I select kernel through the drop down list, nothing happens. It stays on the kernel in the conda environment I'm running the jupyter server from.

If I select "Jupyter: Select kernel" from the command palette, after a few seconds I get a notification about an error:

Running a line from a .py file to interactive window, opens a random kernel among the available conda environments available on the remote machine.

Hi @fohria, could you please open a new issue? This seems to be something else going wrong.
