jupyter server : not started, no kernel in vs code

  1. Press Command+Shift+P on mac, Ctrl+Shift+p on windows

  2. Type Jupyter: Select Interpreter to start Jupyterserver

  3. It would show you a dropdown of python versions installed.

  4. I chose python 3.7.5 and it worked for me you can choose the python version installed on your machine.


I have seen all possible solutions but not work, finally I just upgrade jupyter,notebook,and jupyterlab,like pip3 install -U jupyterlab, and I can choose the kernel in VScode!


I had exactly the same problem when I installed Visual Studio Code and tried to run some Python code from a jupyter notebook on my fresh Ubuntu 18.04.

How I solved it:

1) Press Command+Shift+P to open a new command pallete

2) Type >Python: Select Intepreter to start jupyter notebook server

3) Open the notebook again

And it worked fine. Hope it works for you.


I have several versions of Python installed. It happened the same thing to me and I have fixed it this way. Ctrl+Shift+p and select Python: Select Interpreter to start Jupyter server enter image description here

Then, select the version under the Visual Studio Code enter image description here

Nothing will happen and then press again Ctrl+Shift+p and select Python: Create new blank Jupyter Notebook. And it works

I have even set the Python version to 3.8 at the bottom and it worked too with the new features print(a:=4) despite the fact that the version I have chosen was 3.7.5. Nevertheless, I have to lunch VS Code from Anaconda Navigator.
