【问题描述】：

我正在尝试绘制 k-means，但出现此错误：

'DataFrame' object has no attribute 'label'

我找到了this similar question，但它没有给我所需的答案。

print(df.head().to_dict())

【问题讨论】：

请将print(df.head().to_dict())的结果添加到问题中。 :)
df.head().to_dict() 的结果，而不是代码本身。您需要在您提供的代码（引发错误的代码）之前而不是之后添加此代码。
是的@Mohamed，我的意思是你应该执行该代码并粘贴它的输出，正如 Quang 所说。
所以你的数据框中没有label 列。
另外你在这行有一个语法错误：label = 'Centroids')

标签： python pandas dataframe

【解决方案1】：

错误 'DataFrame' object has no attribute 'label' 试图告诉您您的代码正在向 DataFrame 询问名为“label”的列，但问题是：您该 DataFrame 中没有名为“label”的列。

那么你真正想使用哪一列？
