If reduction is NONE , this has shape [batch_size, d0, .. dN-1] ; otherwise, it is scalar. (Note dN-1 because all loss functions reduce by 1 ...

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.

May 02, 2017 · Just recently I have upgraded my Torch build from 0.1.11 to 0.1.12. Since I have done so, however, I can’t perform a backward pass on a loss object. I get the error: AttributeError: ‘BCELoss’ object has no attribute ‘backward’. Below is the code I use.

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。
