The different results when running plan_guided.py twice with a fixed seed seed=1

Hello, when running plan_guided.py with a fixed seed seed=1, I ran the script twice with identical parameters, but why are the results different each time?

Hello, when running train.py and train_values.py, do I need to fix the random seed to a specific value, such as seed=1? The default seed is None.
