ImageClassifierCleaner does not load the widgets

I am continuing from my first lesson of bird_or_forest and following along the second lesson on fastbook. I am trying to run the following cell:

cleaner = ImageClassifierCleaner (learn)

Where learn is of type vision_learner
The output is stuck with a message

Loading widget…

There are no dropdown boxes to allow me to edit or delete.
Also, the images are printed in column not horizontal.
I am on Kaggel and I am on Firefox browser on Mac, if that matters.


Same issue, any suggestions ? have you got it resolved ?

Nope. That is still an open issue. There are some reports about this. My understanding so far is that it has got to do with ipywidgets. As suggested here, I tried to upgrade ipywidgets, and I got an incompatibility error.
This issue is discussed here too. But, no solution.
Please update this issue if have this resolved.

It seems to be working on Google Colab.

Mine outputs like this:

KeyError Traceback (most recent call last)
File ~/miniconda3/envs/fastbook/lib/python3.10/site-packages/PIL/, in _save(im, fp, filename)
638 try:
→ 639 rawmode = RAWMODE[im.mode]
640 except KeyError as e:

Anything useful?
