I'm trying to do a scatter plot matrix in python, this is the code I have:

import seaborn as sns df_scatter = df._get_numeric_data()

df_concise = df_scatter[['mpg','cylinders','displacement','horsepower','weight','acceleration','year']] sns.pairplot(df_concise, hue='origin', markers=['+','o','-'])

Whenever I try to run it gives out this error:

KeyError: 'origin'

Any idea on what I'm doing wrong?
