floWeaver does not draw basic diagrams from quick tutorial and does not show error message

Question

Following the floWeaver tutorial and beginning with the Quickstart where flows are defined, the second step of plotting the flows does not work. The problem is that I do not get any error message.

The code consists of two blocks, with the second block not working..

import pandas as pd
flows = pd.read_csv('simple_fruit_sales.csv')

from ipysankeywidget import SankeyWidget
SankeyWidget(links=flows.to_dict('records'))

Python version installed: 3.6.10

floWeaver version: 2.0.0

Many thanks in advance!

Answer 1

Just make sure that you have the following installation, other than the package itself.

pip install ipysankeywidget

jupyter nbextension enable --py --sys-prefix ipysankeywidget

jupyter nbextension enable --py --sys-prefix widgetsnbextension
