Проблема Seaborn с кошачьим сюжетом

Я следил за кодом в новой версии seaborn 0.9.0, отображаемым на сайте, и при вводе следующего кода у меня возникла ошибка. Код взят снизу этой страницы https://seaborn.pydata.org/tutorial/categorical.html

import seaborn as sns
tips = sns.load_dataset("tips")
sns.catplot(x="day", y="total_bill", hue="smoker",
            col="time", aspect=.6,
            kind="swarm", data=tips);

Это результат выполнения приведенного выше кода. Я попытался создать новую среду, и все было обновлено. Я до сих пор не знаю, почему не работает.
