Error when using leftLabels/rightLabels

if len(labels > 0):

pretty sure this should be len(labels) > 0...

       df_compare['pred_RF'].values,
       colorDict=colorDict,
       figure_name='visualization/output/sankeytest',
       rightLabels=['C','I','R','P','AUX'])```

yields

Nice addon @endolith ! Although it does not seem to work for fork of forks.

Just to help out others coming after this issue and related ones:

Installing pySankeyBeta works, the error regarding len(labels) > 0 is fixed, the "problem" is:
leftLabels and rightLabels must be provided in a Bottom-Top order to the sankey function.
For example: if you want A, B, C, D to be your left labels, appearing in that order from the top to the bottom of the figure, then leftLabels = ['D','C','B','A']

It is a small detail, but I did not find it mentioned anywhere. I just discovered it by chance.

Hope it helps others!
