JN 7 → tqdm_notebook(leave=False) → Error displaying widget: model not found

[MichalRIcar]

Hi,

This message appears only in JN 7 (not in JN<7) and obviously comes from the fact that tqdm widget is discarded by param "leave=False".

The Jupyter Notebook 7 together with the very last versions of packages (all installed on 27.7.2023) and so far everything works smoothly, however, a minor bug is when using tqdm_notebook(leave=False) inside another widget then in JN is reported "Error displaying widget: model not found".

The code logic is as follows:

from   ipywidgets         import  interactive
from   tqdm.notebook      import tqdm_notebook

def x():
    for i in tqdm_notebook(['a'], leave=False):
        1

interactive(x)

I have reported the issue to tqdm team too.

Best,
Michal

Thanks @MichalRIcar for reporting 👍

There seems to be the same issue in JupyterLab too:

I have reported the issue to tqdm team too.

Looks like this is probably an ipywidgets issue. Can you open this in https://github.com/jupyter-widgets/ipywidgets?

@MichalRIcar it looks like you opened an issue, jupyter-widgets/ipywidgets#3812, in the ipywidgets repository. I see it was closed but as there are recent followup comments, I've linked it here to better track the outcome of that issue.
