Versions

• ipyannotations==0.5.1
• superintendent==0.6.0

Minimal script to reproduce (running via voila==0.4.0)

from superintendent import Superintendent
from IPython.display import display
from ipyannotations.text import MulticlassLabeller

label_classes = ['one', 'two', 'three']
labelling_widget = MulticlassLabeller(options=label_classes, allow_freetext=False)

if __name__ == '__main__':
    widget = Superintendent(labelling_widget=labelling_widget)
    a = [123, 123, 123]
    widget.add_features([a, a, a])
    display(widget)

Getting the following error with this minimal script
