I have the same issue. Exact same error.

[olliescase]

Same issue on:
MacBook Pro M2 13" 2022 (MacOS 13.4.1 (c))

Ran setup for python using /opt/homebrew/opt/python@3.11/Frameworks/Python.framework/Versions/3.11

I have additionally tried installing manually this notebook package via pip to no success. Here is the log, sanitised:

... Ensuring /Users/{name}/Library/Jupyter/instances/{uuid} exists
... Ensuring /Users/{name}/Library/Jupyter/instances/{uuid}/config exists
... Ensuring /Users/{name}/Library/Jupyter/instances/{uuid}/data exists
... Ensuring /Users/{name}/Library/Jupyter/instances/{uuid}/config/custom exists
... Ensuring /Users/{name}/Library/Jupyter/kernels exists
... Starting Notebook server
    > "/opt/homebrew/opt/python@3.11/Frameworks/Python.framework/Versions/3.11/bin/python3" "/Applications/Azure Data Studio.app/Contents/Resources/app/extensions/notebook/resources/pythonScripts/startNotebook.py" --no-browser --ip=127.0.0.1  --no-mathjax --notebook-dir "/Users/{name}" --NotebookApp.token={token}

And this produces the following error:

Failed to change kernel. Kernel SQL will be used. Error was: Notebook process exited prematurely with error code: 1. StdErr Output: Traceback (most recent call last): File "/Applications/Azure Data Studio.app/Contents/Resources/app/extensions/notebook/resources/pythonScripts/startNotebook.py", line 1, in <module> import notebook.notebookapp ModuleNotFoundError: No module named 'notebook.notebookapp'

I believe this is a duplicate of #23945

I have exactly the same issue & error - running ADS on Win10.

Same for the co-worker I'm trying to resolve the issue for - all I had to do to replicate his error was to install ADS on Win10 & try to open a Python Notebook. Python install went through without issue.

Actually I solved that problem

The best way is to delete all python version from your computer after that verify by typing in cmd

code: python --version

go to advance environment setting and delete the path of python after that uninstall your azure data studio and download the latest version of azure data studio

after download anaconda environment and by that you can use jupyter in your any IDE like vs code and after change the kernel in azure data studio you can get the python3

Think this should be closed as its a duplicate of #23945 (and diagnostics/workarounds are being made in both)

Without uninstalling/removing python at all, if notebook is installed via pip, you can just do:

pip3 install notebook==6.5.5

Edit: sorry this didn't mean to sound so aggressive - upon re-reading it felt like it might have come across that way! Good job in finding the issue and getting to a solution, I just meant to say that it would probably save people some time to consolidate where the feedback and contributions to this bug are going

[Vinayak1812]

thanks for giving me this another way @olliescase I will definitely try this .

[AmmarSahyoun]

Solved! By downgrading the version of notebook from 7.0.1 to 6.5.5 Many thanks @olliescase.
