question about the seed args #85

Closed wayunderfoot closed 4 years ago

wayunderfoot commented 4 years ago

I have lots of interests in deepRL,in particular the SAC algorithm.But i can not find the seed args explicitly,could anyone help me figure out what is the function of seed,thanks!

vitchyr commented 4 years ago

It's generated in launcher utils

Firstly thanks for your quickly reply and contribution to open source. I am feeling very sorry for not seeing your reply immediately.But i can't find the call to run_experiment and run_experient_here in SAC impletition from example/sac.py.could you clarify it to me?I am a beginner for pytorch and DRL feeling appreciated getting your reply,thanks!

vitchyr commented 4 years ago

Ah, good point! The example doesn't called run_experiment. Yes, so it looks like I don't explicitly set the seed in those example scripts. Frankly, I tend not to worry about the different seeds (I think by default they're randomly initialized).

If you do want to set the seed yourself, I recommend looking at: https://pytorch.org/docs/stable/notes/randomness.html
