what does "learn_final_eept" mean?

[liujianzhao6328057]

('learn_final_eept', False, 'learn an auxiliary loss for predicting final end-effector pose')

I have some doubt about the flag" learn_final_eept", what does it mean? Because I see that in all the demo files in "scripts ", " learn_final_eept" is set to False.
Thank you.
