Hi, thanks for your reply. could you please explain what update guides?
I write a dataloading class which includes a getitem function. The functions basically use PIL to load a image and do some transformations. I use getitem to load all images and count the time. I find that 1.0 is slower than 0.3.1. My guess is that maybe in 1.0 tensor has both the function of tensor and variable in 0.3.1, which resulting in some additional computing ?
