Just FYI, we already doing it in the CI, not sure if it's helpful to do something like that for all users...
May be add a paragraph saying to uncomment those if you want fixed output all the time

I think it's good practice to have it being part of the script and I'd keep it here.
It helps when you run it locally - RL is very seed dependent usually

seed = 42
random.seed(seed)
torch.manual_seed(seed)
env.reset(seed=seed)
env.action_space.seed(seed)
env.observation_space.seed(seed)
if torch.cuda.is_available():
torch.cuda.manual_seed(seed)
