[BUG] - ipywidgets in JupyterLab behaves different if installed in Dockerfile

[fauxneticien]

What docker image(s) are you using?

base-notebook

OS system and architecture running docker image

macOS/aarch64 (Mac Mini) + BinderHub

What Docker command are you running?

docker build . -t jupyter/base-notebook:lab-3.4.2_ipywidgets and then docker run --rm -p 8888:8888 jupyter/base-notebook:lab-3.4.2_ipywidgets

Dockerfiles:

I have tried both:

FROM jupyter/base-notebook:lab-3.4.2

RUN pip install ipywidgets

and, trying to solve it the same way as #1434,

FROM jupyter/base-notebook:lab-3.4.2

RUN jupyter lab clean --all && \
    pip install --no-cache-dir --upgrade ipywidgets && \
    jupyter labextension install @jupyter-widgets/jupyterlab-manager

How to Reproduce the problem?

Build Docker file, open a new Python 3 Console in JupyterLab then run:

from tqdm.auto import tqdm
from time import sleep

for i in tqdm(range(3)):
    sleep(1)

Or use Binder: https://mybinder.org/v2/gh/parledoct/tutorials/binderhub?urlpath=lab, built from https://github.com/parledoct/tutorials/blob/binderhub/Dockerfile

Command output

No response

Expected behavior

If you launch a plain jupyter/base-notebook:lab-3.4.2 without ipywidgets, tqdm prompts you to install ipywidgets but at least a progress bar displays. Then, once you install ipywidgets, there is no more warning and a progress bar displays.

Or see Binder: https://mybinder.org/v2/gh/fauxneticien/tqdm-jupyterlab/main?urlpath=lab, built from https://github.com/fauxneticien/tqdm-jupyterlab/blob/main/Dockerfile

Actual behavior

If ipywidgets is installed in the Docker build (e.g. with RUN pip install ipywidgets) then tqdm progress bar does not appear, only Loading widget...

Anything else?

I can get a progress bar to appear if I use from tqdm import tqdm instead of from tqdm.auto import tqdm but that isn't an option because I originally came down this rabbit hole because huggingface_hub uses from tqdm.auto import tqdm in their code (https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/file_download.py#L18). So when the progress bar doesn't show, I can't track how a multi-gigabyte file download is going...

You're using ipywidgets in jupyterlab console.
I don't think they are officially supported.
jupyter-widgets/ipywidgets#2370

I have no idea though why they work when !pip install from the console itself.
As there is no support from the upstream, I think the best way for you is to switch to running your code in notebook, not in console.

I've checked and it works fine in notebooks.

Oh, I see — sorry, then I didn't come across this issue. I'll close this one...

Yep, same

Fair point. Indeed this makes jupyter lab far less appealing (as someone else has also noted...)

+1 for issue above. I generally think of JupyterLab as "all the things jupyter notebook does and more" but this issue rains on the jlab parade in a significant way.
