BUG: tqdm progress bar doesn't progress

[troyraen]

tqdm doesn't seem to be working anymore. The iterator doesn't progress and the time stays at "00:00<?". My guess is that it's from #300. Here's an example screenshot:

Just to confirm, this is just a progress bar thing, the cell was eventually executed and run to completion, right?

[troyraen]

Correct

(Also, note this is in Jupyter itself, the rendering looked reasonable, though now I don't have a preview as the notebooks that used it has other issues as thus executing is turned off in for them in #309 )
