How to use the sumo to calculated the effective mass?

Hello:
I want to calculated the effective mass for many materials and I saw the method about the sumo. But I am a little bit confused how to use it. I need pip or conda install sumo? or I should use a vasp? Can you give me an example? Besides, you say we can determine the effective mass from Boltztrap. So which is better one between the both method (sumo and Boltztrap)?
I am looking forward your reply. Thank you very much.
