ipywidgets seems to work fine for the simplest usages, i.e. just using a slider. However, when trying to use more complex functionality the notebook does not show / display the widgets anymore.
See in the picture:
The simple usage
widgets.IntSlider()
works fine.
However, using ipywidget's interact does not show any widget:
def f(x):
return x
interact(f, x=10)
When I change the editor using the dropdown
and use Jupyter or JupyterLab, everything works as expected without flaws.
