Not able to setup vscode.dev to run Python or Jupyter in browser (without downloading or installing)

I am trying to use online browser based version of visual studio code (https://vscode.dev). I installed the extension Python and Jupyter. But when I try to run any code, I get following error.
"Error loading webview: Error: Could not register service workers: NotSupportedError: Failed to register a ServiceWorker for scope".
Looking for your kind help please.
Thanks.

Fast soluton: Open the terminal and type killall code. Easy & lazy solution: Reboot your computer.
If this does not work, try reinstalling or updating vscode

In my case, this was related to a CORS configuration issue. What fixed it for me was launching the notebook from the terminal with the origin specified:
jupyter notebook --no-browser --NotebookApp.allow_origin_pat=https://.*vscode-cdn\.net
If for some reason that doesn't work, you could try the following as a last resort (bearing in mind this will allow ANY origin):
jupyter notebook --no-browser --NotebookApp.allow_origin='*'

trying to execute ipynb file in vscode for m1 mac but not working

I'm trying to use vscode for python in my m1 macbook pro (2021).
I've installed anaconda / vscode / and jupyter notebook extensions in vscode.
Trying to execute simple python code in ipynb file but it shows an error like this and not working :
I've tried executing same code in original jupyter notebook (in anaconda navigator), and that works.
So I think it's problem of vscode ... while I cannot figure out why.
And for reference there are no empty cells in ipynb file. (Which seems to be general causation of this error message, according to Google)
Any suggestions? Thanks.

How to fix Visual Studio Code Jupyter notebook error?

VScode for python runs perfectly, without any error, problems starts whenever I try to run Jupyter notebook inside VScode.
It starts with Ipython Kernel loading and then it shows Command Failed Error. Any fix for this ? I have no idea what's the problem and I don't know much about the environment and stuffs also.
Thank You.

From your picture, VSCode said Command failed, and it's a very long command. It mainly includes two parts: activate the conda base environment and change the vscode python environment through "Python" extension. And from the top right of the picture, it shows the jupyter server start failed.
So you can try to do two things:
First one: change the environment. Instead of using conda, download and install a global python from the official website. And recommend creating a virtual environment. Then select the environment instead of conda base environment.
Second one: reinstall or downgrade the 'Python' extension(if the first one not work).
This problem can be caused by the package in the environment, so I recommend you just change to another environment.

How to run Python and Jupyter with same virtual env, working with Visual Studio Code

For my current job it would be extremely helpful to be able to configure a virtualenv with the appropiate libraries versions, and be able to run either a python project, or cells in jupyter. This is because some people at my job work with jupyter, and some with Python, and sometimes both, and this way I would have a centralized program that could run both types, which I have not found outsaid of the paid version of PyCharm, which my company does not provide.
I just learned a few days ago about Windows Subsystem for Linux, WSL, and that it can be launched from withing Visual Studio Code, so I feel like this is my best bet to achieve that dual nature of programming from just ONE program, instead of running several like in the past.
As of right now, I have a repository cloned with WSL for a git project with different ".py" files, I open it with VSC, then open the terminal inside VSC, and I can both edit the Python code, and run it on the terminal, using bash commands as I would if I were in Ubuntu (I am doing all this from windows but can switch to Ubuntu if it would mean to be able to do this type of setup).
When I run with "Run Python file in terminal", it uses the virtualenv I have previously created.
The problem is, with Jupyter, it does not detect I have the libraries installed (like Pandas for example)
Description of my process with Jupyter so far: With the WSL console, I launch a jupyter notebook &. I then connect to that server, usin the VSC option for "Specify Local or Remote Jupyter server for connections", use the "Existing" option, copy the URL, then I go to the ".ipynb" file and start running code.
If, in a Jupyter cell, I do
import os
os.environ['VIRTUAL_ENV']
I can see my virtual enviroment. If right after that, I run import pandas I get ModuleNotFoundError: No module named 'pandas'
If I do !pip freeze I can see all the libraries and right versions that I have installed in that enviroment.
I feel like I am almost there but something is missing. My guess is that import might be going to some default installed Python, and not the one from the enviroment, for some reason I am missing.

Solved by doing what this answer suggests. The rest of answers may be of help, too:

Jupyter Notebook does not work fully in Pycharm

I am following these steps to run IPython in the Pycharm IDE. On pressing run button in any cell, I do get below pop-up window
According to the mentioned guide (given link), On pressing OK, I should get following message
But, I am not getting any type of message/response. So, I am not able to see the output of any cell contents. Does anyone know why I am not getting any response on selecting OK?
System Information:
OS: MAC OS 10.10.3
Python: 2.7.10 using Anaconda 2.3.0
Ipython: 4.0.0
Pycharm: pycharm community addition 2016.2

I solved following:
First I followed the reply to the issue jupyter-notebook No such file or directory: 'conda', in short you should do:
conda update nb_conda nb_conda_kernels nb_anacondacloud
Then, I ran my jupyter notebook in my browser. I took note where the Jupyter notebook was running, i.e.
The Jupyter Notebook is running at: http://localhost:8888/
Then I started a new Jupyter Notebook in PyCharm2016.2.2, and when it asked about the Jupyter Notebook URL I changed the default http://127.0.0.1:8888 to http://localhost:8888/
and finally it worked.

For the PyCharm Jupyter notebooks, to see results you need to open up a jupyter notebook.
The reason why you don't just do all your code in Jupyter Notebooks is because Pycharm helps with LaTex integration and many more functions.

According to this answer:
Jupyter notebook server not working with latest PyCharm 2017.2 update. How do I solve this?
You need a package named ”notebook“. I had the same issue and I solved it by installing the package.
