将“bmi.csv”加载到Dataframe中，并使用relplot（）创建数据散点图，x轴为身高，y轴为体重，根据性别对图点进行着色，并根据BMI指数改变点的大小。
我的代码是：

import pandas as pd
import seaborn as sns
df = pd.read_csv('bmi.csv')

BMI = pd.DataFrame(df)
g = sns.relplot(x = 'Height', y = 'Weight', data=df);b

我得到：

Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    g = sns.relplot(x = 'Height', y = 'Weight', data=df);b
