@SimonW
Thanks for reply.
Here is my code but seed is not works as I expected.
def loader():
    DataLoader(..., shuffle=True, ...)

manual_seed = random.randint(1, 10000)
print("Random Seed: ", manual_seed)
random.seed(manual_seed)
torch.manual_seed(manual_seed)
torch.cuda.manual_seed_all(manual_seed)
Use loader() here 1st.
Use loader() here 2nd.
