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

[MichalRIcar]

Hi,

This message appears only in Jupyter Notebook 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 and JN teams too.

Best,
Michal

@MichalRIcar -- thanks for opening the issue! It looks like this may have been addressed in tqdm v4.64.1: tqdm/tqdm#1364.

We'd recommend upgrading and/or checking the version of tqdm; for now we are closing this issue.

@mwcraig, thank you, my version of tqdm is 4.65.0, yet the issue is there..

[MichalRIcar]

the issue persists on Jupyter Notebook 7 and JupyterLab 4.0.3, thus, very last versions

As can be seen by just run code
