Hello, I trained my CNN on PyTorch and have the three lines below as preprocessing:         transforms.Resize(256),
transforms.CenterCrop(224),
transforms.ToTensor(),
transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])  . I am building an android app and I used the code here to build it https://github.com/cedrickchee/pytorch-android/tree/master/app/src 6. I am not sure about what this part of the cpp code means ? And how should I do the preprocessing that I need (center crop and normalize)? Thank you so much for help.
