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.

'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.
