"ValueError: zero-size array to reduction operation minimum which has no identity" on hue usage

[jjisnow]

Hi, I'm trying to use the hue parameter in my charts, but whenever it gets added, the figure fails to trigger.

From the examples at https://seaborn.pydata.org/tutorial/relational.html:

import numpy as np import pandas as pd import matplotlib.pyplot as plt import seaborn as sns sns.set(style="darkgrid") tips = sns.load_dataset("tips") sns.relplot(x="total_bill", y="tip", data=tips);

The above draws correctly, but when I add:

sns.relplot(x="total_bill", y="tip", hue="smoker", data=tips);

An error message is triggered, traced back to _backend_tk.py, backend_tkagg.py

This is also true of any other plots requiring the 'style' parameter in a default scatterplot

This is my Python venv environment, currently using Python 3.8:

certifi	2020.6.20
