Image normalization in PyTorch

Hi, I’m working on an image classification problem. I’m working in PyTorch and I need to normalize the images so that they have a mean 0.0 and a standard deviation of 1.0 (reference: https://cs231n.github.io/neural-networks-2/#datapre ). I implemented the mean subtraction and std division, but I stumbled as the network’s behaviour is strange and I’m not sure with my implementation. Now, this is my transforms settings: transform = transforms.Compose([ transforms.ToPILImage(), transform…
