I have millions of 16x16 pixels images and when I set shuffle=False, the training is fast.
But…When I set shuffle=True, so slow…
How to speed up?
It’s a matter of how do you save images rather than dataloader itself.
Shuffling just shuffles a list of indices. It seems your system is slower accessing non-sequential lists of indices.
How do you do so?
Hi,
Do you mean slow in runtime? Or slow to learn?
Thanks for you reply. I mean slow in run time.
Thanks for your reply, I have solved the problem. Thank you
@QuanHei Hi, same problem here, how do you solve the problem?
I have a very large dataset(1200000 images) and training with shuffle=False is fast while training with shuffle=True is slower and slower.
Any suggesstion or help would be appreciated, thanks!
