Witryna14 mar 2024 · 还有个问题，可否帮助我解释这个问题：RuntimeError: torch.nn.functional.binary_cross_entropy and torch.nn.BCELoss are unsafe to autocast. Many models use a sigmoid layer right before the binary cross entropy layer. ... 举个例子，你可以将如下代码： ``` import torch.nn as nn # Compute the loss using … WitrynaThe add_loss() API. Loss functions applied to the output of a model aren't the only way to create losses. When writing the call method of a custom layer or a subclassed model, you may want to compute scalar quantities that you want to minimize during training (e.g. regularization losses). You can use the add_loss() layer method to keep track of such …
