我正在尝试在CIFAR10 数据集上训练一个非常基本的CNN 并收到以下错误: AttributeError: 'CrossEntropyLoss' 对象没有属性'backward' criterion =nn.

25.11.2020 · 'BCEWithLogitsLoss' object has no attribute 'backward' nlp. svss (Venkata Sai Sukesh Settipalli) November 25, 2020, 5:12pm #1. Hello guys, I’m trying to fine-tune the Bert model i.e., bert-base-uncased for a text classification task. I’m getting a ...

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

'none': no reduction will be applied, 'mean': the sum of the output will be divided by the number of elements in the output, 'sum': the output will be summed. Note: size_average and reduce are in the process of being deprecated, and in the meantime, specifying either of those two args will override reduction.

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.

这个问题我亲身经历，搞了好久，才发现错误，根本原因就是对代码，pytorch等的原理理解不够深入。my_loss(my_y, y)函数忘记给返回值(loss)了， ...

Jun 20, 2020 · if I delete the backward it will involves many variables. my purpose is that the graph retain two output, one is produced image ,the other is real ,they come from same graph i have to use retain_graph=True to make sure grad value will not be cleared by system.

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 ...

x x x and y y y are tensors of arbitrary shapes with a total of n n n elements each.. The mean operation still operates over all the elements, and divides by n n n.. The division by n n n can be avoided if one sets reduction = 'sum'.. Parameters. size_average (bool, optional) – Deprecated (see reduction).By default, the losses are averaged over each loss element in the batch.
