esay way to know if really learning and update .nn model ??

hi
I have made an agent, it is a ball that looks for another. and it works and it finds it and all, but sometimes when I close unity and open it again, and press play, I feel that the ball seems to start disoriented again, even after 2 hours of training finding the other ball, then my question is… without using tensor, how can I know if it is really learning and saving the information in .nn? I am using mac Ventura OS X. thanks for any comments.9899055--1429632--Screen Recording 2024-06-19 at 21.23.04.gif
