In the (analyze_us_tornadoes.ipynb sample](https://github.com/Esri/arcgis-python-api/blob/master/samples/04_gis_analysts_data_scientists/analyze_us_tornadoes.ipynb) The notebook relies on searching for an item: data = gis.content.search('Tornadoes_and_Tracks owner: api_data_owner', 'Feature layer', outside_org=True)

This item is not publicly shared, so it returns no results an the remainder of the process cannot be executed. When I hit the item link in the notebook: https://geosaurus.maps.arcgis.com/home/item.html?id=5c210f1e7ad04c1bbaf991beb13ee905 I get prompted to Sign in to Python API Test.
