I am also beginning and got the same error. What I did to fix this error was to change the dataset path to the one I get when I ask on github to download the csv file.
I am getting other erros tho. So if anyone can explain to me:
After I run the sales.shape, I requested for sales.info and then sales.describe.
Both come wih the same return which are different from what is shown on the video class.
I appreciate any help.
