As I understood from several resources the normalization setting below taken from imagenet but I also wonder the intuition behind it.
transforms.Normalize(mean=[0.485, 0.456, 0.406],
                     std=[0.229, 0.224, 0.225]) 

And for the images with pixel values between [0-1] such normalization may ruin the image as I experienced, I may be wrong though.
