progress bar not showing in jupyter notebok

[ehsong]

Hi, I have a p_map set up in jupyter notebook, but instead of the progress bar, I get:
HBox(children=(FloatProgress(value=0.0, max=1827402.0), HTML(value='')))

I have tried the following in terminal:
jupyter nbextension enable --py widgetsnbextension
jupyter labextension install @jupyter-widgets/jupyterlab-manager

but the issue persists after restarting the kernel.

I have the same issue and I solve it by downgrade ipywidgets, if you also work on VSCODE:
! pip install -U ipywidgets==7.7.1
