$NeRF: Neural Radiance Fields implementation in PyTorch with 100 lines of code | NeRF#5 “`python import torch import torch.nn as nn import torch.nn.functional as F class NeRF(nn.Module): def __init__(self): super(NeRF, self).__init__() # Define neural network layers here def forward(self, input): # Implement forward pass logic here return output model = NeRF() optimizer = torch.optim.Adam(model.parameters(), lr=0.001) # Training loop for epoch in range(num_epochs): for i, data in enumerate(train_loader): inputs, targets = data optimizer.zero_grad() outputs = model(inputs) loss = F.mse_loss(outputs, targets) loss.backward() optimizer.step() if i % 10 == 0: print(f”Epoch {epoch}, Iteration {i}, Loss: {loss.item()}”) “` This code snippet outlines the basic structure of a Neural Radiance Fields (NeRF) implementation in PyTorch. The `NeRF` class represents the neural network model, with customizable layers and a forward pass method. The code also includes an optimizer setup using Adam and a training loop that iterates through batches of training data, calculates the loss, performs backpropagation, and updates the model parameters. The model can be further customized with additional layers, activation functions, and training parameters to fit specific use cases.$
