Installing ArcGIS API for Python via PIP installs ipywidgets version 8.0.4 which is incompatible with the Jupyter Notebook.

Solução Provisória

From a command prompt:

1. Downgrade the ipywidgets package to version 7.7 by entering pip install ipywidgets==7.7.0.
2. Start a Jupyter notebook by entering The Jupyter Notebook.
3. Once the new tab opens, create a new notebook with Python 3 as the kernel.
4. In the first cell of the notebook, enter the following code to create a GIS object and a map view using the arcgis package:

from arcgis.gis import GIS

my_gis = GIS()

m = my_gis.map()

m

Notice the map view widget now loads appropriately.
