word-break:break-all是自动换行。当一个单词到达边界时,下个字母会自动到下一行。

word-break:break-work也是自动换行。将整个单词看成一个整体,如果该行末端宽度不够显示整个单词时,会自动把整个单词放到下一行,而不会把单词截断。

work-wrap:break-work应用效果和word-break:break-work一样。

### Backward Function Context and Usage In the programming context, particularly within frameworks like PyTorch used for deep learning applications, `backward()` plays a crucial role in computing gradients of tensors with respect to leaf variables. This function facilitates backpropagation through computational graphs defined during forward passes. The primary purpose is to calculate partial derivatives that enable optimization algorithms such as Stochastic Gradient Descent (SGD) or Adam optimizer to update model parameters effectively[^1]. When invoking this method on a tensor object representing loss value at the end of each training iteration cycle, it accumulates gradient information into `.grad` attributes associated with all trainable weights involved directly or indirectly via operations performed earlier while constructing graph nodes leading up until current point where backward pass starts executing from terminal node backwards towards initial inputs layer by layer recursively traversing entire structure built so far since last zero_grad call was made before starting new epoch round again after previous one finished processing mini-batch samples completely without any leftovers remaining unprocessed yet still pending inside pipeline buffer queues waiting their turn next time around when another batch comes along soon enough ready for consumption once more. ```python import torch # Example setup model = ... # Define neural network architecture here loss_fn = torch.nn.CrossEntropyLoss() optimizer = torch.optim.SGD(model.parameters(), lr=0.01) # Forward pass: compute predicted outputs outputs = model(inputs) loss = loss_fn(outputs, labels) # Backward pass: compute gradients loss.backward() # Update weights using computed gradients optimizer.step() ``` Common issues encountered include: - **Accumulation of Gradients**: If not properly managed, repeated calls can lead to incorrect updates due to accumulated gradients over multiple iterations. - **Non-scalar Loss Tensors**: The `backward()` expects input tensor to be scalar unless otherwise specified explicitly which might cause errors
