You have to start a new game and when the professor asks you if you want to do a challenge run you answer yes. (You have 3 save files so you can do 3 diffrent games, so you don't have to write over your normal game). You then get to pick between nuzlocke, randomizer and randomlocke challenge. The other challenges aren't available until the next update.
