Hello,
I am running plotly.py version 4.8.2 in a jupyter notebook.
I ran the following code, copied from the documentation page:
import plotly.figure_factory as ff
import numpy as np
np.random.seed(1)X = np.random.rand(10,10)
fig = ff.create_dendrogram(X)
fig.update_layout(width=800, height=500)
fig.show()
and getting the following error message:
KeyError Traceback (most recent call last)
in
4
5 X = np.random.rand(10,10)
----> 6 fig = ff.create_dendrogram(X)
7 fig.update_layout(width=800, height=500)
8 fig.show()~/miniconda3/envs/jupyterlab/lib/python3.7/site-packages/plotly/figure_factory/_dendrogram.py in create_dendrogram(X, orientation, labels, colorscale, distfun, linkagefun, hovertext, color_threshold)

Is there something wrong with the example code? Or maybe something about my environment?
Thanks!
