It is a simplified question from the previous post, I do not know how to delete the earlier one.
I am following youtube python tutorial given by here
I simply copied the notebook in the webpage to generate and run a pipeline (pipeline1), which is shown in the second table.
Then I removed one line about ranking of factor to generate another pipeline (pipeline), which is shown in the first table.
These two tables give entirely different factor column on the same security.
Anybody could explain why these two are different, and which one shall be the correct one?
