This would make BCELoss’s backward method nonlinear with respect to x_n xn , and using it for things like linear regression would not be straight-forward. Our solution is that BCELoss clamps its log function outputs to be greater than or equal to -100. This way, we can always have a finite loss value and a linear backward method. Parameters

''AttributeError: 'float' object has no attribute 'backward''. 的错. ***. 我现在的做法是:把newloss数值加到原来的MSE类型loss上: ```. criterion = nn.

Hi, I've tried the sigmoid cross entropy to compute the loss. Now I have the loss but it says error: AttributeError: 'tuple' object has no attribute ...

25.02.2020 · 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。

Also, ensure that your network output is in the range 0 to 1 in case you use NLLLoss or BCELoss (then you require softmax or sigmoid activation respectively).

Issue resolved. My mistake, I was missing the parenthesis criterion = nn.CrossEntropyLoss().
