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.

Press
Command+Shift+Pon mac,Ctrl+Shift+pon windowsType
Python: Select Interpreter to start JupyterserverIt would show you a dropdown of python versions installed.
I chose python 3.7.5 and it worked for me you can choose the python version installed on your machine.

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
Then, select the version under the Visual Studio Code
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.

Making sure that in VS Code settings.json
"python.condaPath": "C:\\Program Files\\miniconda3\\Scripts\\conda.exe"
is pointing to the correct directory. It solved it for me.

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!

In my case, I had the server working in 3.7.6, but i wanted to use >3.8.0 versions too. After multiple attempts, which failed, I decided to:
- Uninstall 3.8.5, and delete the folder in the installation directory.
- Uninstall VSCode too.
- Restart the PC, and re-install Python and VSCode. As a result, the Jupyter server initiated based on the latest version of Python automatically.
I hope this helps too! Cheers!

just had the same issue and it did not help to update the interpreter within vscode. What helped was: Check your dependencies within pip! It seems that new dependencies came up with the latest update of python, which are not installed. For me this was pygments:
jupyter-console 6.2.0 requires pygments, which is not installed.
Linux solution step-by-step:
xyz@xyz-pc-ubuntu:~$ pip3 check
qtconsole 4.7.6 requires pygments, which is not installed.
nbconvert 5.6.1 requires pygments, which is not installed.
jupyter-console 6.2.0 requires pygments, which is not installed.
ipython 7.18.1 requires pygments, which is not installed.
xyz@xyz-pc-ubuntu:~$ pip3 install pygments
Successfully installed pygments-2.7.2
Afterwards, jupyter found the updated python interpreter automatically.
