WebMar 21, 2024 · We load the images and target variables from the validation set (line 2). Remember, the target variables are tensors of dimension 2. We get the second element for each of the tensors (line 4). This means we will now have a binary target variable — 1 for STOP and 0 for GO. WebJan 7, 2024 · PyTorch implementation for sequence classification using RNNs. def train (model, train_data_gen, criterion, optimizer, device): # Set the model to training mode. This will turn on layers that would # otherwise behave differently during evaluation, such as dropout. model. train # Store the number of sequences that were classified correctly …
