CrossEntropyLoss¶ class torch.nn. CrossEntropyLoss (weight = None, size_average = None, ignore_index =-100, reduce = None, reduction = 'mean', label_smoothing = 0.0) [source] ¶ This criterion computes the cross entropy loss between input and target. It is useful when training a classification problem with C classes.

08.06.2020 · 一、问题描述 编写自己的loss 函数时， loss.backward() 在反向传播一会后，就报错：'float' object has no attribute 'backward'二、原因： 报错的原因是output，也就是损失函数这里输出了int值。但是在实验过程中，梯度确实是下下降了。只是总是在下降过程中出现了这种报错。
