Python Seaborn 绘图值错误

Question

我有一个 pandas 数据框 df 并且正在尝试使用 seaborn 库创建一个小提琴图。

    rank  sentiment category
0     1   0.657413        m
1     2   0.895769        m
2     3  -0.435457        m
3     4  -0.717959        m
4     5   0.869688        m

这是seaborn线：

sns.violinplot(x="rank", y="senitment", hue="category", data=df)

我一直收到这个 ValueError

ValueError: Could not interpret input 'senitment'

完整追溯

    538         self.establish_colors(color, palette, saturation)
    539         self.estimate_densities(bw, cut, scale, scale_hue, gridsize)

    145                 if isinstance(input, string_types):
    146                     err = "Could not interpret input '{}'".format(input)
--> 147                     raise ValueError(err)
    148 
    149             # Figure out the plotting orientation

ValueError: Could not interpret input 'senitment'

我试过在 df 上使用 .reset_index() 并更改数据类型，但没有成功。想法？
