I cannot submit my assignment through Jupiter, it says “history.pkl is missing”, I tried to get the latest version of the lab in Lab Help. While still missing that file, I do not know what should do. Could you please reset my Jupiter lab for the assignment “Programming Assignment: Exploring overfitting in NLP”, then I can restart everything from the very beginning. Thank you so much. My lab id is “yhdxzqkz”, many thanks.
