sorry @hsm I only just saw this. it's a good idea, although it means that fastprogress won't work unless ipywidgets is installed. how about only using ipywidgets in the case where the user is on vscode?

BTW, you need to nbdev_install_git_hooks to ensure you have a clean NB in your PR.

Hi, I hit this bug in VSCode and used the monkeypatch @hsm wrote in this post here to fix it:

from IPython.display import clear_output, DisplayHandle
def update_patch(self, obj):
    clear_output(wait=True)
    self.display(obj)
DisplayHandle.update = update_patch

Any chance some sort of fix can be merged into the main branch? It's been impacting quite a few users I think for over 2 years now.

@guillochon note that progress bars were working in VSCode and only stopped a few days ago. This is an old PR that I guess was fixed in a different way. Here is the new issue https://github.com/fastai/fastprogress/issues/104

Either way your workaround is useful for the current issue, thanks. You may want to post your workaround on the issue, it is closer to the intended output than the suggestions.
