WebMay 18, 2024 · There's something weird about the dimensions of X_train and y_train. They automatically have the same number of rows after train_test_split, but for some reason you do reshape (-1,1) on X_train. This changes the number of rows for X_train, so of course it doesn't have the same number of rows as y_train, hence the error.
