Pytorch validation
WebPyTorch uses torch.tensor, rather than numpy arrays, so we need to convert our data. import torch x_train, y_train, x_valid, y_valid = map( torch.tensor, (x_train, y_train, x_valid, y_valid) ) n, c = x_train.shape print(x_train, y_train) print(x_train.shape) print(y_train.min(), y_train.max()) WebAug 19, 2024 · There are 2 ways we can create neural networks in PyTorch i.e. using the Sequential () method or using the class method. We’ll use the class method to create our …
