Multiple TQDM progress bars: You probably need to run some code to see this widget

I have a notebook that is running several TQDM based progress bars in Jupyter notebook mode (from tqdm.auto import tqdm).

For some reason I am getting a warning "You probably need to run some code to see this widget." for some of the progress bars.

I am also getting different errors like

It seems to work flakily, though, so I am not sure what's the root cause here.

I read the ticket. Based on the discussion on the ticket, is there is a safe older ipywidgets version which one can downgrade to?

I double checked ipywidgets version:

docker-compose exec cocalc pip3 list

ipywidgets                      7.7.5

Something before 7.x.

This ticket is high priority though, so hopefully I'll have fixed this soon. I may get to tackle it this coming week.
