how can i get different random source in every episode in the reinforcement trian?

how can i get different random source in every episode in the reinforcement trian?

I am training the PPO agent. In order to facilitate reproduction, it starts with rng0, but my model uses the random source module. I find that every time the epiode is started, the values are the same. How can I make the random source module values in each epiode different？，every episode，its numer is same.
