When I ran this line of code: train_dummies = train_dummies.drop([Income_ <=50K'], axis=1) I got an error saying there is no such variable. I looked up all the dummy variables and actually only "Income_ >50K" exists. Can you please help? Thanks.

Hi, What comes to my mind is that you may have already run the cell that dropped the variable, so if you run it again, it is going to spill out an error. Please make sure to restart the kernel and try again. Another possibility is that you set the parameter drop_first to be True instead of False. Hope this helps! Best, Nikola, 365 Team
