vscode python jedi client: couldn't create connection to server

Question

I keep getting this message when I run Jupyter Notebook.

I think you should probably ask here: https://github.com/microsoft/vscode-jupyter/ — Dave Halter, May 13 '22 at 07:51

Pylance is now the default language server (see here). As such, I resolved the issue by changing my settings.json to:

"python.languageServer": "Pylance"

You may need to install the Pylance extension, if you don't already have it.

I met this issue on Ubuntu 18.04 LTS with python interpreter python3.6.9 + VS code python extension 2022.14

So the reason should be:

The new version python extension is not compatible with old python version 3.6.9.

Solution:

either downgrade the python extension to 2022.06(can be even earlier, not fully tested); or upgrade the python interpreter version.

it is my case. After changing interpreter env 3.6 -> to -> 3.8 all error pop-ups disappeared. — ati ince, Dec 08 '22 at 14:44

Check whether the following code is specified correctly in your setting.json:

"python.languageServer":"Jedi"

Change `python.languageServer` value to `Default` is work for me. – LianSheng May 25 '22 at 09:44
