The issue is that results is a list of lists, and you’re trying to create a DataFrame from it. When you use zip(), it creates an iterator that aggregates the values from each element in the lists into tuples, which are then converted to Series when creating the DataFrame. To achieve your desired format, you need to reshape the data before creating the DataFrame. You can do this by using the values() attribute of each model’s value accessor to get the values as a 2D array, and then using pd.
