What is 'seed' argument intended for?

[antiero]

Just wondering about the --seed command line argument...

What is the purpose of this argument? I can see that it gets used by torch.manual_seed, but is this supposed to allow you to get a deterministic image output when re-running with the same prompts for a given number of iterations?

I've tried re-running with the same seed number and get different image output so assume it's not expected to allow for deterministic output?

I'm a noob to pytorch so please excuse me!
