BUG: Progressbar rendered multiple times in Jupyter

[fonnesbeck]

Describe the issue:

This appears to be a regression. Running a Jupyter notebook (either in JupyterLab or in VSCode) shows multiple copies of the progress bar. Does not occur in marimo.

Reproduceable code example:

Any `pm.sample` call with progress bar enabled.

Error message:

PyMC version information:

PyMC 6.2.0, Python 3.13.14. PyTensor 3.2.3

Context for the issue:

No response

Never seen it, so not reproducible just like that,... but progress bars don't run well in ipykernel>=7 so I've downgraded it to 6. which ipykernel are you running on?

[fonnesbeck]

Aha. Currently on 7.3

[fonnesbeck]

Apparently not entirely the fault of ipykernel

[ricardoV94]

Can you try regular jupyter, or ipython without vscode?

Removing the runcell Jupyter extension appears to fix the problem. Has the dual effects of fixing the progressbar issue and disabling the AI agent sidebar in Jupyter, so win-win.
