Here's my code: from torchvision import datasets, transforms, models model = models. when I wanted to write some differentiable decision tree it took me way longer in TF (I already knew) than with PyTorch, having its tutorial on another pane. edu is a platform for academics to share research papers. ResNet-164 training experiment on CIFAR10 using PyTorch, see the paper: Identity Mappings in Deep Residual Networks - model. Project was made for educational purposes and can be used as comprehensive example of PyTorch C++ frontend API.
