python - 类型错误 : 'DataFrame' object is not callable error when using seaborn pairplot ?

Question

我是 python 和机器学习的新手，并尝试学习该主题，我正在学习在线类(class)，我已经在 jupyter 笔记本中导入了一个数据集，并尝试在其上执行以下 python 脚本

#creating a scatter plot matrix
%matplotlib inline

import seaborn as sns
num_cols = ["Age","Height","Weight","Duration","Heart_Rate","Body_Temp","Calories"]
sns.pairplot(frame(num_cols),size=2)

我的数据集如下

但是当我运行代码时我得到

TypeError Traceback (most recent call last) in () 4 import seaborn as sns 5 num_cols = ["Age","Height","Weight","Duration","Heart_Rate","Body_Temp","Calories"] ----> 6 sns.pairplot(frame(num_cols),size=2)

TypeError: 'DataFrame' object is not callable

作为初学者，如果有人可以提供帮助，我找不到解决方案 非常感谢。

谢谢。

Answer 1

您应该创建一个中间 DataFrame:

import pandas as pd

%matplotlib inline

import seaborn as sns
num_cols = ["Age","Height","Weight","Duration","Heart_Rate","Body_Temp","Calories"]
df = pd.DataFrame(columns=num_cols)
sns.pairplot(df,size=2)
