Jupyter Notebooks not displaying progress bars

The progress bar does not show up, instead it is showing HBox(children=(FloatProgress(value=0.0, max=1.0), Label(value='In progress...')))

$ jupyter nbextension enable --py widgetsnbextension

# assuming you have already installed nodejs and jupyterlab

# otherwise you need to install nodejs and jupyterlab first (pip install jupyterlab)

$ jupyter labextension install @jupyter-widgets/jupyterlab-manager
