ValueError:无法解释输入“Rating”

Question

我想在我的文件中添加一个图形，它显示了以下错误，并打印了一个空图形。我想要在具有值(1,2,3,4,5)的评级列和每个评级中的行数之间绘制一个图表。代码如下：

sns.set(rc={'figure.figsize':(6,6)})
plt.title('Distribution of Ratings')
sns.countplot(x = 'Rating', Edata = Edata);

错误是：

ValueError: Could not interpret input 'Rating'

Answer 1

您应该传递数据参数，而不是edata

sns.countplot(x='Rating', data=Edata);
