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

02.05.2017 · 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 'bac…

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

Backward is the function of PyTorch Tensor. When you called the loss.tolist(), you broke each computation graph and you can't backward from ...

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).

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。

''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.
