Can't execute k3d widget notebook

[joyceerhl]

Testing microsoft/vscode#177719

1. Open https://github.com/microsoft/vscode-jupyter/blob/main/src/test/datascience/widgets/notebooks/k3d_widgets.ipynb
2. Install k3d
3. Run first cell
4. 🐛 Cell never completes, no errors in output or dev tools

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to verbose
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel.

[DonJayamanne]

Works for me, please do share the verbose logs

[joyceerhl]

Still repros for me, sent you logs on Slack @DonJayamanne

• Can you try another version of Python, (try another kernel)
• Can you also check if there are any errors in the console window (vscode dev tools)
• Also please could you check whether this same notebook runs in the asme Python environment

Ensure you install python -m pip install jupyter notebook into the same python kernel environment and launch jupyter from there using python -m jupyter jupyter notebook and try it ouc.

So I went and split out all the lines in that notebook, and it looks like this succeeds:

https://insiders.vscode.dev/github.com/microsoft/vscode-jupyter/blob/adfc442a2178eff34d9cdc5aa049acecfbc9e8a9/src/test/datascience/widgets/notebooks/k3d_widgets.ipynb#C4:L1-L9

But executing this line never returns

Thanks, but that doesn't help, as I have no idea what that library does.
Please could you try #13131 (comment)

Tried with Python 3.10 from the Windows store, also didn't work.
No errors in dev tools or Jupyter console.
This notebook runs in the selected Python environment as confirmed with import sys; print(sys.executable)

[joyceerhl]

Weirdly, if I run python3 -m pip install jupyter notebook from the CLI, I get a message saying that all packages are already installed, and if I rerun the k3d notebook, the cell still fails to complete. But if I run import sys; !{sys.executable} -m pip install jupyter notebook in a notebook cell, then the cell completes. So I think the k3d library and/or the ipywidgets library have not declared a dependency on the notebook submodule that is really required to execute that library's code. I don't think this is a Jupyter extension problem at all, probably something that needs fixing in k3d and/or ipywidgets.

[DonJayamanne]

robably something that needs fixing in k3d and/or ipywidgets.

Great, thanks for digging into this, will close this issue.

FYI: Instead of using python3 -m pip install, you need to activate the python environment you are working on and then run

• python -m pip install or
  Use this for virtual environments, conda envs and the like
• <fully qualified path to Python> -m pip install, use the latter when dealing with globally installed python environments like Python in windows store or the like.
