Question

我正在按照网站上显示的最新seaborn 0.9.0版本中的代码进行操作，输入以下代码时出现错误。代码来自页面https://seaborn.pydata.org/tutorial/categorical.html

的底部

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);

这是运行上述代码的输出。我尝试创建一个新环境，并且所有内容均已更新。我仍然不知道为什么它不起作用。

Answer 1

很遗憾，这是matplotlib 3.0.1中的错误。据here报道，并由pull/12673修复。

您必须选择安装matplotlib 3.0.0或3.0.2。
