[Python] Can't run Jupyter Notebook in VSCode - Vanilla Python, Windows 10

I have an existing vanilla Python installed on my Windows 10 computer and I do not want to reinstall Anaconda.

When trying to run code from ipynb file in vscode, I get the following error:

Error: Jupyter cannot be started. Error attempting to locate jupyter:

Also with the following error from VSCode:

ⓘ Couldn't find kernel 'Python 3' that the notebook was created with. Re...

ⓧ Jupyter server crashed. Unable to connect. Error code from jupyter: 1

Below are some of the things I have tried:

Check if the VSCode Extension in Correctly Installed

"Jupyter" extension is deprecated. I had the "Python" plugin from Microsoft installed which contained Jupiter Notebook support.

Jupyter Installed Correctly

I tried reinstalling jupyter:

> python -m pip install --upgrade pip
> pip install jupyter
> pip install notebook


Tried to Run Jupyter on Terminal/Command Line

> jupyter notebook //didn't work
jupyter : The term 'jupyter' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.

+ jupyter

This gave an error not able to find jupyter executable. According to this post I tried the following and it worked: How to fix "'jupyter' is not recognized as an internal or external command, operable program or batch file" when running Jupyter on Windows?

> python -m notebook


Check if pointing to the right interpreter

As per "https://stackoverflow.com/questions/60330837/jupyter-server-not-started-no-kernel-in-vs-code" I tried:

1. Press Command+Shift+P to open a new command pallete
2. Type >Python: Select Intepreter to start jupyter notebook server

But I only had one version of Python installed on my computer, and doing this didn't make a difference.

Check the Path

There was this comment about PYTHONPATH on "https://stackoverflow.com/questions/19917492/how-can-i-use-a-python-script-in-the-command-line-without-cd-ing-to-its-director" but since the python directory is correctly referenced and python works from the command line, I did not investigate it further.

One thing to note is pip installs to my "C:/Users/[username]/appdata/Roaming/Python-38/" folder while my Python is installed in "C:\Program Files\Python38-32\".
